Problems solved by technology

[0005] However, when the construction soil is soft sandstone or contains a lot of water, it is very inconvenient to use artificial or mechanical excavation and sinking. In addition, if the water pump is used to drain the caisson, it is possible when the depth is shallow , but when the caisson reaches a certain depth, not only the drainage is inconvenient, but also the strong water pressure around the caisson will easily crush the caisson

Embodiment 1

[0029] Such as figure 1 , 2 , Shown in 3, a kind of vertical mud-water balance construction device, it comprises caisson, caisson is rectangular, and caisson has double well wall. A water tank with a sealed bottom is formed between the inner well wall 3 and the outer well wall 4, that is, the bottom of the inner well wall and the outer well wall are connected together, and the gap between the inner well wall and the outer well wall in each direction is Two water tanks are isolated, a working well is isolated between the two water tanks, and a working well is also isolated at each corner of the rectangular caisson.

[0030] There is a blade foot 5 under the sealed bottom, and an independent blade foot is provided at the lower end of the well wall in each direction. The blade foot is a hollow triangular blade foot made of steel plate. A high-pressure water pump is installed inside each blade foot hollow. Of course, it can also be The pump is installed outside, and the high-pre...

Embodiment 2

[0035] Such as Figure 6 As shown, the difference from Embodiment 1 is that the blade foot is a triangular blade foot made of steel plate, one edge of the triangle bottom of the blade foot is connected to the bottom of the outer well wall through a hinge shaft 11, and the other edge is connected to the inner well wall. A hydraulic cylinder 12 that controls the rotation of the blade foot around the hinge shaft is arranged between them. In order to control the movement of the blade foot through the expansion and contraction of the hydraulic cylinder when the blade foot is stuck, and accelerate the downward movement of the caisson.

Abstract

The present invention provides a vertical slurry balance construction device, belongs to the technical field of architectural engineering devices, and relates to an open caisson construction device. The problems that in the prior art, when an open caisson reaches a certain depth, drainage is inconvenient, and the open caisson is easily crushed due to high water pressure around the open caisson are solved. The vertical slurry balance construction device comprises an open caisson; the open caisson has double-layer caisson walls; water tanks with sealed bottoms are formed between the inner-layer caisson wall and the outer-layer caisson wall; blade feet are disposed below the sealed bottoms; each blade foot is provided with a water spray nozzle; drill pipes capable of rotating relative to the open caisson are disposed at the bottom port of the inner-layer caisson wall; and the drill pipes are provided with helical blades. According to the vertical slurry balance construction device, the open caisson can be adapted to the water environment soil property, sink of the open caisson is achieved by using water, water pressure balance inside and outside the open caisson is maintained, and buckling failure of the open caisson is prevented.

Description

technical field [0001] The invention belongs to the technical field of construction engineering equipment, and relates to caisson construction equipment, in particular to a caisson device with mud-water balance. Background technique [0002] In underground construction, it is generally used in the construction of foundation pits of large bridge piers, sewage pumping stations, large equipment foundations, civil air defense shelters, shield assembly wells, underground lanes and station hydraulic foundation construction enclosures. The caisson construction method has higher construction efficiency. [0003] The caisson is mainly composed of the blade foot and the well wall. Shaft wall: The outer wall of the caisson is the main part of the caisson. It should have sufficient strength to withstand the load during the sinking process and use of the caisson; It can sink smoothly. Blade foot: The lower end of the well wall is generally made into a blade-shaped "blade foot", whose ...
