Description

Drainage system in foundation ditch

Technical Field

The utility model relates to the technical field of foundation pit construction, in particular to an internal drainage system of a foundation pit.

Background

In the foundation pit construction process, the foundation pit area is big, and independent foundation and pile cap hole are many, and ponding appears in the hole easily, and ponding pump drainage in the hole in time will greatly influence the construction progress. At present, a drainage open ditch is usually arranged in a large foundation pit for foundation pit drainage, and water in a bearing platform pit is drained into the open ditch by adopting pumping equipment and a water hose.

Under the condition that foundation ditch is many, cushion cap hole is many, adopt hosepipe drainage in a large number and can lead to the foundation ditch in the working face very in disorder, foundation ditch water receiving pump drainage one by one, inefficiency and extravagant manpower also can make the construction have certain potential safety hazard simultaneously.

SUMMERY OF THE UTILITY MODEL

In order to overcome the defects of the technology, the utility model aims to provide an in-foundation-pit drainage system.

The technical scheme adopted by the utility model is as follows: a drainage system in a foundation pit comprises a water collecting well, two water pumps, a main drainage pipe and two main drainage pipes which are respectively arranged on one side of a left foundation pit group and one side of a right foundation pit group, the left side foundation pit group and the right side foundation pit group both comprise a plurality of foundation pits, one side of each foundation pit is provided with a diesel self-priming pump, the water inlet of the diesel self-priming pump is connected with a water suction pipe, the water outlet of the diesel self-priming pump is connected with a drainage branch pipe, the water suction pipe extends into the bottom of the corresponding foundation pit, the drainage branch pipe is communicated with the main drainage pipe close to the drainage branch pipe through a three-way pipe, one port of the three-way pipe is closed, the other two ports are respectively connected with the corresponding main drainage pipe and the drainage branch pipe, the water outlet ends of the two main drainage pipes extend into the upper part of the water collecting well, the two water pumps are arranged at the lower part in the water collecting well, and the water outlet ends of the two water pumps are communicated with a main drainage pipe through connecting pipes.

Furthermore, a plurality of supports for supporting the main drainage pipe are arranged below the main drainage pipe.

Furthermore, the two main drainage pipes are arranged in parallel.

Compared with the prior art, the utility model has the following beneficial effects: according to the drainage system in the foundation pit, the water pumps are not needed to be connected with the foundation pit one by one, a large amount of water hoses are not needed to be used for drainage, and the disorder of the working surface in the foundation pit is avoided. Compared with an electric water pump, the diesel self-sucking pump avoids the trouble of long-distance wire arrangement, has better maneuvering advantage, can be arranged more quickly and flexibly, can operate immediately, and large construction machines such as excavators on construction sites adopt diesel power, and fuel is sufficient and easy to obtain. After the foundation construction is completed, the water drainage branch pipe and related accessories are removed, and the main water drainage pipeline can also be used as a construction water supply pipeline in the basement construction stage, so that the material is effectively saved. The utility model eliminates the potential safety hazard of construction electricity utilization, is more rapid to install, can rapidly arrange the water pump to carry out pumping and drainage operation after the foundation bearing platform pit has accumulated water, saves the preparation time for arranging a large amount of water hoses and connecting and wiring, and effectively ensures the construction progress.
