Modular ecological drainage ditch blocks and ecological drainage ditch formed

technical field

The invention relates to the improvement of civil engineering technology, in particular to a modular ecological drainage ditch block and a drainage ditch formed by the block, and belongs to the technical field of civil engineering.

Background technique

In many civil engineering projects, it is often necessary to build standardized drainage ditches, such as drainage ditches in rural land. At present, the materials for building drainage ditches are mainly various stones or concrete blocks, and special tools and various auxiliary materials are also needed during actual construction. The existing drainage ditch mainly forms a U-shaped structure with a bottom surface and two sides through stone or concrete blocks. The stone or concrete blocks forming the bottom surface and two sides are connected end to end to form the required length, so the workload It is very large, inefficient, and has certain technical requirements for craftsmen, which cannot be done by ordinary workers, otherwise the built drainage ditches may not meet the quality requirements.

In addition, the existing drainage ditch only considers the drainage needs, but does not consider ecological factors. For example, some small animals or insects originally wanted to reach the other side from one side of the drainage ditch during the migration process, but due to their own capabilities and the design of the drainage ditch The reason is that they often fall to the bottom of the ditch and cannot climb out by themselves. In the absence of food, they may starve to death or be roasted to death by the sun, which will have an impact on the ecology.

Contents of the invention

In view of the above-mentioned deficiencies in the prior art, the object of the present invention is to provide a modular ecological drainage ditch block with fast construction speed, no technical requirements, scientific and reasonable design and ecological effect, and a drainage ditch composed of the block.

In order to achieve the above object, the technical scheme adopted in the present invention is as follows:

Modular ecological drainage block, the main body of the block is rectangular, and a vertical drainage groove is provided on the upper surface of the main body of the block. The upper surface of one end of the main body of the block forms a downward step I, and a horizontal through-hole is provided on the step I. The lock groove Ⅰ, the lock groove Ⅰ forms the lock Ⅰ by the groove wall of the end;

The lower surface of the other end of the main body of the block forms an upward step II corresponding to the step I. The height of the step II from the lower surface is the same as the height of the lock groove I in the step I from the lower surface. The step II is provided with a horizontally penetrating lock groove II. , the depth of lock groove II is the same as that of lock groove I, and the wall of lock groove II near the end forms lock II; the size of lock groove II and lock I match so that the lock groove II of one block can connect the other The catch I of a building block is covered.

Further, there are two parallel longitudinal biological passages vertically interpenetrating inside the block and below the drainage groove, and a transverse biological passage is provided horizontally through and simultaneously connected with the two longitudinal biological passages inside the block below the drainage groove . Creatures can transfer and pass through the vertical and horizontal biological channels inside the block.

Furthermore, horizontal sand-blocking partitions are provided on the bottom of the drainage ditch on the main body of the block, and vertical steps at different heights are provided on the two side walls of the drainage ditch to facilitate the crawling of organisms up and down.

The modular ecological drainage ditch proposed by the present invention is formed by buckling the modular ecological drainage ditch blocks end to end. When buckling, the lock II of one of the blocks is located in the lock groove I of the other block. The lock groove II of the block covers the lock catch I of the other block, and after fastening, the upper and lower surfaces of the two adjacent blocks are respectively flush.

Compared with the prior art, the present invention has the following beneficial effects:

1. The block is easy and fast to install. It only needs to be buckled from the end to the end. The efficiency is greatly improved, and there is no requirement for installation technology. Ordinary people can construct it after simple training. Due to the modular design, the fastening parts are very well combined, and its function is to drain water. Appropriate leakage is allowed, so there is no need for additional work such as seam filling after fastening.

2. The block has a good ecology, and organisms can transfer and pass through the vertical and horizontal biological channels inside the block, providing a good living environment for it. Simultaneously, organisms can also pass through the drainage ditch laterally through the steps on the two side walls of the drainage ditch easily, and the situation of being unable to pass and being trapped at the bottom of the ditch will not occur.

3. The present invention is equipped with a sand blocking partition on the main body of the block. After the water overflows the partition, it can continue to flow forward, while the sediment is effectively intercepted. After a large amount of sediment deposition, it can be cleaned and backfilled nearby, which can avoid mud The sand will be lost along the drainage ditch under the washing of rainwater, and the amount of loss will be large after a long time. Therefore, this block can effectively avoid water and soil loss.

Detailed ways

The present invention will be described in further detail below in conjunction with the accompanying drawings.

Referring to Fig. 1, as can be seen from the figure, the modular ecological drainage ditch block of the present invention, the main body 1 of the block is rectangular, and the upper surface of the main body 1 of the block is provided with a vertical drainage groove 2, and the drainage groove 2 The cross section is arc-shaped. A downward step I is formed on the upper surface of one end of the main body of the block, and the step I is provided with a horizontally penetrating lock groove I3, and the lock groove I3 forms a lock buckle I4 near the groove wall at the end.

The lower surface of the other end of the main body of the block forms an upward step II corresponding to the step I. The step I and the step II have the same size and dimension, and the height of the step II from the lower surface is consistent with the height of the lock groove I in the step I from the lower surface. . On the step II, there is a lock groove II5 that runs through horizontally and matches the lock buckle I. The depth of the lock groove II5 is the same as that of the lock groove I3. The size of the buckle I4 is matched so that the lock slot II5 of one block can cover the lock buckle I4 of the other block.

After the block adopts the modular design, it can be directly processed by the building material manufacturer in the factory like a brick and then transported to the construction site. First, the trench is manually dug on the ground along the direction of the proposed drainage ditch, and then the block Put it in the trench and buckle it end to end to form a drainage ditch of the required length, and finally fill the two sides of the block with soil and compact it. The installation is convenient and fast, the efficiency is greatly improved, and there is no requirement for installation technology, ordinary people can construct after simple training. Due to the modular design, the fastening parts are very well combined, and its function is to drain water, and proper leakage is also allowed, so there is no need for additional seam repairs after fastening.

Inside the block, there are two parallel longitudinal biological passages 7 (the cross-section is circular in actual design) that are vertically connected under the drainage groove 2. The horizontal biological channel 8 (the cross section is rectangular in actual design) connects the two longitudinal biological channels 7 . Creatures can transfer and pass through the vertical and horizontal biological channels inside the blocks. In addition to considering the passage of organisms from the ground, the present invention also considers that the organisms may pass through the drainage ditch laterally from the ground. In fact, because the drainage ditch has a certain depth and the wall surface is relatively smooth, it is often difficult for weak organisms to pass through, and may be trapped to death in the end. The bottom of the ditch is not conducive to ecological stability. In view of this, the present invention is provided with longitudinal steps 9 at different heights on both sides of the drainage ditch 2, which are convenient for organisms to crawl up and down, which simply solves the problem of organisms passing through the drainage ditch on the ground.

Furthermore, in the present invention, a horizontal sand-blocking partition 10 is provided on the block main body 1 at the bottom of the drainage ditch, which actually plays the role of Shigu Fang intercepting the sediment, so that the water can continue to move forward after passing through the partition, and the mud The sand is effectively intercepted. After a large amount of sediment deposition, it can be cleaned and backfilled nearby, which can avoid the loss of sediment along the drainage ditch under the erosion of rainwater. Over time, the loss will be large. Therefore, this block can Effectively avoid soil erosion. The height of the sand-blocking partition is just right, too high is not conducive to drainage, and too low is not conducive to sediment interception, so the actual design needs to be considered comprehensively. In another sense, the sand-blocking partition becomes the reinforcing rib of the block, which can improve the strength of the block and has a double effect.

The modular ecological drainage ditch proposed by the present invention is formed by buckling the modular ecological drainage ditch blocks end to end. During fastening, the lock II of one of the blocks is located in the lock slot I of the other block, and at the same time the lock slot II of the block covers the lock I of the other block. After fastening, the upper and lower surfaces of two adjacent blocks are respectively flush, and the longitudinal biological channels are connected to each other.

Finally, it is noted that the above embodiments are only used to illustrate the technical solutions of the present invention without limitation. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be carried out Modifications or equivalent replacements without departing from the spirit and scope of the technical solution of the present invention shall be covered by the claims of the present invention.
