Embodiment Construction
[0039] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific illustrations.
[0040] In order to fully illustrate the working principle of this new type of pressurized drainage system, we will make a structural section of a pressurized vacuum flexible tube well as shown in figure 1 Compared with the traditional vacuum tube well profile such as figure 2 List them together. from figure 2 It can be seen that the traditional vacuum tube well is composed of a steel pipe 12, a porous steel pipe wrapped around a filter pipe 14, a granular filter material 15 and a sealing clay sphere 13 at the drainage part, and a vacuum tube 11 and a drain pipe 17 are arranged in the well pipe. When it is a tube well with a larger diameter, a submersible pump is directly provided inside for drainage. The bottom of the tube well is provided ...

The invention discloses a pressurized vacuum flexible tubular well dewatering and drainage system and a construction method thereof. The vacuum flexible tubular well comprises a tube shoe, a filteringtype flexible tube, a sealing tube, an air pumping and water draining tube and a connecting joint, wherein the tube shoe is positioned at the lower part of the vacuum flexible tubular well; the upperpart of the tube shoe is in shape of a hollow tube, and the lower part of the tube shoe is in shape of a tube cone; and the bottom part of the tube shoe is sealed; the filtering type flexible tube isa hollow circular tube; a tube body is prepared by coiling an elastic framework with porous filtering cloth; the sealing tube is a hollow hard tube and is positioned at the upper part of the filtering type flexible tube; and the air pumping and water draining tube is a hollow hard tube and is positioned in the filtering type flexible tube. The dewatering and drainage system comprises a pluralityof pressurized vacuum tubes, a tubular well connecting tube, an air and liquid separating tank, a one-way overflowing valve, a main water draining tube, a vacuum pump and an air compressor. The systemachieves the purpose of quickly dewatering and draining water.
Description
technical field [0001] The invention relates to the fields of foundation reinforcement, deep foundation pit reinforcement and soft soil excavation, in particular to a method for rapid drainage and consolidation from silt soft soil. Background technique [0002] When constructing roads and buildings in soft soil areas, it is necessary to strengthen the silt soft soil. The most common method is to quickly increase the strength or bearing capacity of the silt soft soil through drainage and consolidation. However, the current Both the sand well treatment method and the vacuum drainage method have problems such as long drainage time, difficult drainage and silting of the drainage plate, which are difficult to meet the engineering needs. [0003] During the development of underground space, a large number of deep foundation pits appear continuously. Due to the existence of groundwater, the construction of foundation pit engineering often faces the problem of dewatering and draina...
