Embodiment Construction

[0028] The present invention will be further described below in combination with specific embodiments.

[0029] The invention is a self-sealing device for a drainage board, which consists of two parts: a sealing body 1 on the top of the drainage board and a water and air suction pipe 2 . Drain board board body 3 adopts conventional drain board, can be plastic drain board, also can be papery or other materials.

[0030] The length of the sealing body of the self-sealing device is about 50-500mm, and its specific size is determined by the properties of the surface soil in the reinforcement area. There is a connecting hole on the top or side of the self-sealing device. The diameter of the hole is about 16mm. The specific size can be determined comprehensively according to the pipe diameter of the suction and drainage connecting pipe system. The drain board can be directly connected to the drainage system through the suction pipe.

[0031] The sealing forming method of the self-...

Abstract

The invention relates to a drainage plate self-sealing device, which consists of a sealing body coated or stuck on the upper part of the drainage plate and a water and air suction pipe; the underside of the drainage plate is open; the superface of the drainage plate is also open and positioned in the sealing body of the self-sealing device; the periphery of the upper part of the drainage plate body is sealed; and the sealing body is coated or stuck on the periphery of the upper part of the drainage plate body. The sealing body of the upper part of the drainage plate is a box-shaped cylinder. The water and air suction pipe of the self-sealing device is a right-angle and bended-angle pipe. The device is used in the vacuum prepressing and can save a plastic sealed film for reinforcing the surface layer, a film outgoing device and a film pressing sealed ditch, a horizontal drainage undercourse and total filter pipes. The device is used in the load prepressing and can save the horizontal drainage undercourse. The device is used in the well point precipitation prepressing and can use the drainage plate and the self-sealing device to replace a lightweight well point with expensive price, shorten the construction period and improve the precipitation speed; and the device is used in the prepressing and reinforcing technology and can save manpower, engineering material and engineering investment, simplifies the construction procedure, shortens the construction period and improves the precipitation speed. The vacuum degree can reach between 80 and 95 kilopascals below zero.

Description

technical field [0001] The invention relates to a drainage plate self-sealing device used in the drainage consolidation reinforcement of the civil engineering foundation or the precipitation preloading reinforcement. Background technique [0002] As a vertical drainage body for drainage consolidation, the drainage board is widely used in the drainage consolidation method of foundation soil. According to its material, there are mainly paper drainage boards and plastic drainage boards, and plastic drainage boards are the most widely used in engineering. [0003] Plastic drainage board is a new vertical drainage material proposed by O. Weger (1971) after Kjellman (1934) invented paper drainage board. Made of cloth. my country began to develop plastic drainage boards in the 1980s. In the early 1980s, our institute, together with Hohai University and Tianjin Port Authority, successfully conducted a field test in Tianjin Port for the first time and applied it to large-scale soft...
