Description
Technical field
The present invention relates to architectural engineering construction technique field, in particular, it is related to a kind of underground pipe gallery drainage construction side
Method.
Background technology
Underground pipe gallery is exactly that underground urban duct integrates corridor.I.e. Urban Underground build a tunnel space, by electric power,
Communicate, the various utilities pipelines such as combustion gas, heat supply, draining are integrated in one, provided with special access hole, hoisting port and monitoring system,
Implement unified planning, Uniting, the unified important infrastructure and " lifeline " built and managed, be guarantee city operations.
Underground pipe gallery will have high requirement in work progress, due to underground at position, so drainage problem just exists as underground pipe gallery
A highly important link in work progress, in the prior art, uses general draining in the work progress of underground pipe gallery
Method, by excavating a gutter, makes water be flowed out along gutter, and this method completely can not arrange the ponding in foundation ditch
Go out, when monitoring drainage situation, conventional method needs artificial real-time monitored drainage situation, and efficiency is low, and to draining result without
The high-quality monitoring of method.
The content of the invention
The purpose of the present invention is to be directed to above particular problem, in order to overcome the defect of prior art, so as to provide a kind of row
A kind of underground pipe gallery drainage and construction method that water efficiency high and drainage situation can be monitored efficiently.
A kind of underground pipe gallery drainage and construction method proposed by the present invention：
Step one：First row ditch is excavated outside along excavation of foundation pit upper limb line, surface smears one layer of M10 cement mortar, uses coagulation
Earth mulch plate covers the first gutter；
Step 2：Lay dewatering well outside along the foundation ditch upper limb line at 0.3~0.6m in a ring, well depth is Xm, and X's takes
The first wireless senser carried when value passes through excavation and precipitation well on drill bit is determined；
Step 3：The groundwater mining in dewatering well is discharged into the first gutter with water pump；
Step 4：Excavation pit, at Foundation Pit bottom, surrounding sets the second gutter and periphery catch pit, periphery catch pit hole
Inside set simple filtration cage；Set in the middle of foundation ditch in central catch pit, central catch pit hole and set simple filtration cage, periphery catch pit
Set aqueduct to central catch pit, central catch pit hole bottom sets the second wireless senser.
Further, the first gutter in described step one is away from 1.5~2.5m outside excavation of foundation pit upper limb line.
Further, the first wireless senser in described step one is liquid level wireless sensor, passes through radio communication
Network sends hydraulic pressure information and gives signal receiving terminal.
Further, the well spacing of the dewatering well in described step two is 20~25m.
Further, after the dewatering well in described step three draws water 5~9 days, foundation pit construction is carried out.
Further, the bottom surface of the central catch pit in described step four is than the low 3~6m in periphery catch pit bottom surface.
Further, the bottom surface in the second gutter in described step four 0.5~0.6m lower the Foundation Pit bottom of than, second row
Ditch bottom surface is than the low 0.1~0.2m in periphery catch pit bottom surface.
Further, the second wireless senser in described step four is liquid level wireless sensor, passes through radio communication
The hydraulic pressure information that network is sent in central catch pit gives signal receiving terminal.
Further, the filtrate of periphery 3~6mm of catch pit filling diameter in described step four.
Further, the wide 1~1.5m in the first described gutter, deep 1~1.5m, thickness is 0.1~0.15m.
Further, first wireless senser is acquired analysis to the water pressures of underground environment around, if
Hydraulic pressure then sends hydraulic pressure information to signal receiving end continuously less than predetermined value by cordless communication network, signal receiving end according to
Hydraulic pressure information determines the working condition of drill bit；Signal receiving end is received after hydraulic pressure information, is sent and is received to the first wireless senser
Success confirmation, the first wireless senser can not have successfully received the feedback information of signal receiving end, then the first wireless senser
The follow-up information transmit power of increase simultaneously sends abnormal alarm sound.
Due to area and the difference of environment, the height of its underground water is different, will during underground pipe gallery drainage construction
A variety of situations just occur, during excavation and precipitation well, the first wireless senser is set on drill bit, it is anti-according to the first wireless senser
The information of feedback, can accurately monitor the situation of underground water very much, while the really depth X of well.
Further, second wireless senser is tested the water in central catch pit, and by hydraulic pressure information
Signal receiving end is fed back to by cordless communication network, signal receiving end determines the intensity of drawing water of water pump according to hydraulic pressure information, and
Determine the need for being adjusted water pump quantity；When hydraulic pressure information is more than predetermined value, the second wireless senser is anti-by information
Feed the signal receiving end；Signal receiving end is received after hydraulic pressure information, is received and is successfully confirmed to the transmission of the second wireless senser
Information, if the second wireless senser, which can not have successfully received, receives successfully confirmation, the increase of the second wireless senser is follow-up
Information transmit power and send abnormal alarm sound.
Beneficial effect：A kind of drainage and construction method that the present invention is provided, devises the first gutter, dewatering well, foundation ditch,
Two gutters, periphery catch pit and central catch pit, underground water and underground ponding can pass through drainage and construction method of the present invention
It is rationally efficient to exclude, construction quality is improved, the engineering time is saved, by introducing the first wireless senser and the second wireless sensing
Device monitors construction quality, and the drainage problem occurred during building use is notified into draining unit in time.
Other features and advantages of the present invention will be illustrated in the following description, also, partly becomes from specification
Obtain it is clear that or being understood by implementing the present invention.The purpose of the present invention and other advantages can be by the explanations write
Specifically noted structure is realized and obtained in book, claims.
