The foundation pit refers to a soil pit excavated at a foundation design position according to the base elevation and the base plane size, namely, a foundation space below the ground excavated for the construction of a building (including a structure) foundation and a basement. When the building engineering construction is carried out, a foundation pit mostly needs to be excavated, and because the construction of the building foundation pit generally takes a long time, a drainage system needs to be arranged on the foundation pit during the construction.
With the rapid development of the building industry, under the large background that the country vigorously pushes green and environment-friendly production, the traditional open trench drainage system is difficult to meet the comprehensive requirements of drainage efficiency, civilized construction, green construction, energy recycling and the like in the building construction stage. Before bottom plate concrete pouring, the basis is located the foundation ditch bottom, and whole height fluctuates, and grade beam, cushion cap, elevartor shaft form the sump pit of keeping off each other, and ponding can't collect the drainage, only can drop into a large amount of water pumps and manpower and take out water, and the drainage effect is lower, is difficult to satisfy the job site requirement, especially meets rainstorm, heavy rainstorm, even during super heavy rainstorm, and the drainage can't in time, all discharge foundation ditch to will not satisfy the requirement that the foundation ditch was under construction under dry condition. In order to achieve the purposes of preventing slope instability, pit bottom piping, foundation bearing capacity reduction and the like, foundation pit dewatering, underground diving, construction water consumption and natural rainfall are required to be eliminated.
At present, use the open drain to get rid of the water in the building foundation ditch usually, only lead water in the sump pit that simply dug is made, it clears up it to recycle the water pump, long-term use the water in the foundation ditch collect with lead to in the sump pit the pressure inhomogeneous of soil layer, it is also different to lead to the bearing capacity in the soil layer of different regions when building, easily cause harm to building in the foundation ditch, need timely clearance water in the sump pit simultaneously, waste time and energy, and be difficult for carrying out reutilization to the water in the sump pit, cause the waste of resource.
Patent CN 204298837U discloses a light and dark drainage system, comprising: the dewatering well is arranged beside the foundation pit and used for collecting underground water so as to reduce the water level of the foundation pit; the open drainage ditch is arranged on the ground surface and used for collecting surface water; the water collecting well is communicated with the dewatering well and the open drainage ditch, and water in the dewatering well and the surface water in the open drainage ditch are collected through a water pump; the underground water pipe is arranged underground and communicated with the water collecting well so as to lead out water in the water collecting well; and the sedimentation tank is communicated with the hidden water pipe and is used for settling and filtering the water led out by the hidden water pipe. This patent can collect groundwater through setting up dark drain pipe and bright escape canal, reduces the ground water level of foundation ditch annex, can collect surface water again, prevents that surface water from corroding the foundation ditch and making and leaking around the foundation ditch, has solved the problem of big engineering building foundation ditch dewatering drainage. However, there are disadvantages that, firstly, the automatic drainage function cannot be realized, the purpose of fully utilizing natural resources cannot be realized, and the energy cannot be fully reused. Secondly, the water collected to the precipitation well cannot be collected and discharged, only a large amount of water pumps and manpower can be used for pumping and draining water, the drainage effect is low, and for example, when rainstorm, heavy rainstorm and even extra heavy rainstorm occur, the drainage cannot be timely and completely discharged out of the foundation pit, so that the requirement of the construction of the foundation pit under the dry condition cannot be met.
Furthermore, patent CN 109898532 a discloses a drainage system for a foundation pit of a building, which comprises a water channel, a water pool a, a water pool b and a water valve, wherein the bottom plate of the water pool is designed to be inclined from high to low, at least one guide way and at least one mud pushing plate are arranged on the bottom plate, and at least one rope hole is arranged at the bottom of each of the left and right ends of the water pool. The bottom of the right side of the water tank is provided with a drain hole, and a mud blocking mechanism is arranged in the water tank and close to the bottom plate. The water pool is provided with a cover plate, the cover plate is provided with a fixed pipe and 1 top hole, and the right side of the water pool is provided with a boss for a water supply pump; the automatic structure of the water valve comprises a string, two fixed pulleys, a rotating shaft, a rotating handle, a fixed plate, a spring, a fixed boss, a hook, a rotating buckle and two plastic buckets. Although the above patent uses the mechanical automatic operation system of the water valve to make the waste water flow separately according to the condition of each water pool, the unmanned operation is realized. There are disadvantages, however, such as, firstly, that they do not allow an efficient re-use of energy. Secondly, it cannot intelligently control the diversion, but the machine operates automatically. Thirdly, it needs the manual work to clear up the silt on the mud scraper, takes trouble and laboursome.
