At present, a foundation pit is excavated in a sand gravel section, and the defects that underground burial is shallow, surface water is rich, the construction period is influenced by precipitation, construction processes and the like, the problems of foundation pit settlement, slope collapse, substrate water seepage and the like frequently occur in construction, and the influence is brought to the construction operation stage. The existing solutions include measures such as water intercepting tanks, impervious walls, sheet piles or grouting curtains, drooping skirts and the like, and although the methods can block underground water, the methods have the disadvantages of large water pumping amount, large construction difficulty and poor economic benefit.
Disclosure of Invention
The utility model aims to solve the problems that the water pumping quantity is relatively small and the construction difficulty is reduced. The technical scheme is as follows:
a sand gravel section leading pipe well dewatering construction structure is characterized by comprising a dewatering well and a rainwater inspection well, wherein the mouth of the dewatering well is provided with a cover of the dewatering well, the mouth of the rainwater inspection well is provided with a cover of the inspection well, a water filter pipe is arranged at the bottom in the dewatering well, and a gravel layer is filled between the water filter pipe and the dewatering well; the top opening of the water filtering pipe is butted with a well pipe, a drainage branch pipe is led out from the well pipe and is connected into a rainwater inspection well, and a construction dewatering drainage pipe and a municipal rainwater main pipe are led and connected onto the rainwater inspection well.
The bottom of the strainer is wrapped with a nylon net.
The submersible pump is installed in the water filtering pipe, and the drainage branch pipe is connected to the drainage end of the submersible pump.
The dewatering well is composed of a concrete pipe with the inner diameter of 300-500 mm.
The strainer is of an annular structure.
Compared with the prior art, the utility model has the beneficial effects that:
1. the construction structure comprises the dewatering well and the rainwater inspection well, the structure is reasonable, the segmental construction is convenient, and the normal excavation of earthwork in the foundation pit can be ensured.
2. The sand gravel section forepoling well precipitation construction structure enables the underground water level to be kept below the bottom of the foundation pit by 2m during foundation pit excavation and underground structure construction, improves the safety of engineering, and enables the total amount of extracted underground water to be minimum and the engineering investment to be most economical on the premise of achieving foundation pit precipitation.
