Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of foundation treatment, in particular to a shallow silt foundation drainage device. BACKGROUND

[0002] As a special type of geological structure, the shallow silt foundation is widely present in rivers, lakes and coastal areas, and its high water content and low strength characteristics pose significant challenges to engineering construction. In the foundation treatment of infrastructure construction such as roads, bridges and buildings, effective drainage is crucial to improve the bearing capacity and stability of the foundation. The vacuum preloading method is the most widely used treatment method, which involves laying a sealing membrane on the surface of the foundation, using a special vacuum equipment to extract vacuum, laying drainage boards and drainage channels on the foundation, continuously pumping air and water, forming negative pressure in the sand cushion under the sealing membrane and the vertical drainage channels in the soil, accelerating the drainage of pore water, and thus causing the foundation to settle, the foundation soil to gradually consolidate, and the foundation strength to be improved.

[0003] The existing drainage device generally uses a drainage pipe of fixed length for the drainage treatment of the shallow silt foundation. The drainage position is fixed and cannot be adjusted according to the position changes of the silt layer. Reinstalling the long pipe is relatively cumbersome, and as the drainage operation continues, the water in the silt layer is extracted, and the geological structure also changes. These changes are often accompanied by redistribution of soil stress, and the installed pipe is prone to deformation under pressure, resulting in pipe damage and deformation, affecting the drainage effect.

[0043] Working principle of the present application:

[0044] Step one, by rotating the control valve 14 through external force, rotating the control valve 14 drives the rotating of the movable pipe 21, and makes the movable pipe 21 rotate along the inner wall of the positioning pipe 22, because the outer side of the movable pipe 21 is provided with threads, and the inner wall of the positioning pipe 22 is provided with thread grooves matched with the threads of the outer side of the movable pipe 21, so that by controlling the rotating direction of the movable pipe 21, it can move downward along the inner wall of the positioning pipe 22, because the overall length of the water suction pipe 2 is lengthened, and the position of the movable pipe 21 is moved, so as to adjust the water pumping position of the water suction pipe 2, at the same time, as the movable pipe 21 moves downward, the supporting mechanism 25 moves away from the inner wall of the positioning pipe 22, and because the second magnetic ring 256 is attracted to the first magnetic ring 221 arranged on the inner wall of the positioning pipe 22, so that when the movable pipe 21 moves downward, the second magnetic ring 256 is fixed in position under the attraction of the first magnetic ring 221, so that the rack 255 is fixed in position, and because the rack 255 is engaged with the limiting ring 254, when the movable pipe 21 moves downward, the limiting ring 254 rotates, when the limiting ring 254 rotates, the position of the clamping block 2541 changes, when it corresponds to the clamping groove 2531 opened on the outer side of the push plate 253, the spring 257 loses pressure and rebounds, so that under the elastic force of the spring 257, the push plate 253 passes through the limiting ring 254, and the support frame 252 is pushed forward, and under the elastic force of the spring 257, the support frame 252 is fixed in the underground pipe wall where the movable pipe 21 is installed;
