Embodiment Construction

[0033] see Figure 1-Figure 3 , a kind of air cushion type vacuum tube well layered dewatering device that the present invention relates to, it comprises tube well 5, and the middle part of described tube well 5 is provided with air cushion type vacuum tube well layered dewatering device, and air cushion type vacuum tube well layered dewatering device includes inner ring cover plate 6 and an air gasket 7 made of rubber, the inner ring cover plate 6 is provided with four slideways 6.4 arranged in a cross, and each slideway 6.4 is provided with a slide plate 6.5, and the slide plate only needs to be manually passed through the slideway during use. The main function is to support the cover plate of the inner ring, especially under the condition of vacuuming, when the vacuum negative pressure reaches 60KPa, the sliding plate supports the wall of the tube well, which can prevent the huge suction force from The cover plate of the inner ring is sucked off to destroy the vacuum. When ...

Abstract

The invention discloses an air cushion type layered vacuum tube well. The air cushion type layered vacuum tube well comprises a tube well body; an air cushion type vacuum tube well layered dewatering device is arranged in the middle of the tube well body and comprises an inner ring cover plate and an air cushion ring which is made of rubber materials; four slideways which are arranged in a crossed mode are arranged on the inner ring cover plate; a sliding plate is arrangde on each slideway; a vacuum pump connecting tube hole is upwards connected to a vacuum generating tube; a vacuum meter connecting tube hole is upwards connected to a vacuum meter tube; a cable and sinking pump rope hole is upwards connected to a cable and a sinking pump rope tube; a drainage tube hole is downwards connected to a drainage connecting tube and is upwards connected to a drainage tube; the two sides of the inner ring cover plate are downwards provided with water drain tubes; and the air cushion ring is arranged below the inner ring cover plate. The air cushion type layered vacuum tube well and a soft foundation dewatering and draining method applying the same have the advantages that different dewatering construction can be carried out on different soil, and the double effects of tube well dewatering and vacuum dewatering can be achieved by one tube well.

Description

technical field [0001] The invention relates to an air-cushion type layered vacuum tube well and a method for lowering and draining water on weak ground using the same. The method is used for rapidly lowering the groundwater level on the soft ground, and the method can reduce construction cost, reduce labor intensity, and improve construction efficiency. It belongs to the technical field of foundation treatment. Background technique [0002] At present, the large-area soft soil foundation reinforcement treatment and foundation pit excavation in the construction industry all involve lowering the groundwater level to meet the requirements of reducing the water content of the soil. The method of lowering the groundwater level of the soil is generally realized by the method of well point precipitation and tube well precipitation. In these two processes, the tube well precipitation can reach a depth of less than 20m due to the insertion of the soil, and rely on the principle of ...
