High water level soft foundation drainage construction device and method

Abstract

The application relates to a high water level soft foundation drainage construction device, which belongs to the field of water conservancy engineering construction, and includes a plurality of tube wells. A plurality of water seepage holes are opened, and a suction pipe is installed in each tube well. The high water level soft foundation drainage construction device also includes a water pump. The input end of the water pump is provided with a drainage pipe, and each water suction pipe is connected to the drainage pipe. Set, the end of the suction pipe located in the tube well is provided with a filter element, the filter element includes a first filter cartridge coaxially arranged with the tube well, the end of the suction pipe penetrates and extends into the first filter cartridge, and the first filter cartridge A plurality of first filter holes are provided, and the first filter holes re-filter the infiltrated water entering the tube well, thereby preventing impurities in the infiltrated water from affecting the suction pipe and the drain pipe, thereby preventing damage to the water pump.

Description

technical field [0001] The present application relates to the field of water conservancy engineering construction, in particular to a high water level soft foundation drainage construction device and method thereof. Background technique [0002] Weak foundation is composed of layers of soft soil such as sediment, peat and silty soil. It has low porosity, poor bearing capacity, and difficult drainage and consolidation. It is a typical problem that is often encountered and difficult to deal with in foundation construction, especially in water conservancy. It is quite common during the construction of engineering facilities. When carrying out pile foundation construction on the soft foundation, need to extract the water in the weak foundation to ensure the strength and stability of the pile foundation after construction. [0003] The Chinese patent application publication number CN108691310A discloses a drainage consolidation system and method for soft soil foundation. Vacuum ...

AI Technical Summary

Problems solved by technology

[0004] The above-mentioned related technologies have the following technical defects: the accumulated water in the ground can be filtered through the geotextile and then enter the vacuum well point tube through the through hole on the vacuum well point tube, and the water will be drained by the submersible pump and the drainage pipe in the vacuum well point tube. However, when actually installing the geotextile-coated vacuum wellpoint tube, it is necessary to use a pile driver to drive the geotextile-coated vacuum wellpoint tube into the ground. When entering the ground, impurities such as gravel in the ground will scratch the geotextile, making the geotextile lose its filtering effect, resulting in a large amount of impurities in the water entering the vacuum well point pipe through the through hole, and the impurities in the water will be on the drainage pipe. Cause blockage, and even cause damage to the submersible pump in severe cases
