Problems solved by technology

However, the traditional loading and sinking scheme is difficult to accurately control the stability of the caisson sinking space attitude, the construction risk is high, the production cost is high, the operability is poor, and it is very easy to cause the caisson to sink, suddenly sink, and shift. And other issues

Embodiment Construction

[0035] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0036] sinking device

[0037] see figure 2 , figure 2 It is a schematic diagram of the three-dimensional structure of the caisson with the sinking device according to the first embodiment of the present invention. The sinking device of the caisson in the figure includes: a prefabricated pile 2 used to support the caisson structure body 1, a two-way receiving pile between the caisson structure body 1 and the prefabricated pile 2, which is firmly connected with the caisson structure body 1 Force jack 3, the two-way force jack 3 is used to support and drag the caisson structure body 1; it is used to fasten the axial connector 4 connecting the two-way force jack 3 and the precast pile 2. The present invention utilizes the two-way stress jack 3 fastened to the caisson structure body 1 and the prefabricated pile 2, which can support the caisson structur...

Abstract

The invention discloses a sinking device of an open caisson, comprising a precast pile used for supporting an open caisson structure main body. The sinking device of the open caisson is characterized by comprising a bidirectional stress jack and an axial connector, wherein the bidirectional stress jack is tightly and fixedly connected with the open caisson structure main body and positioned between the open caisson structure main body and the precast pile, and the bidirectional stress jack is used for upwards supporting and downwards drawing the open caisson structure main body; and the axial connector is used for tightly and fixedly connecting the bidirectional stress jack with the precast pile. Because the invention utilizes the bidirectional stress jack tightly and fixedly connected with the open caisson structure main body and the precast pile, the sinking device of the open caisson can be used for supporting the open caisson structure main body in the sinking process of the open caisson and also can be used for drawing the open caisson structure main body. Therefore, the dead weight of the open caisson is reduced, and the controllable, precise and stable sinking of the open caisson is realized; in addition, the invention further discloses a sinking method of the open caisson with the sinking device.

Description

technical field [0001] The invention relates to a sinking device for a caisson and a sinking method for a caisson with the device, in particular to a sinking device for a caisson that is safe, controllable, precise in displacement movement, and sinks smoothly and has the device. The sinking method of the caisson of the device. Background technique [0002] As a structure for underground space structures or deep foundations of high-rise buildings or deep foundation pit support construction, caissons have their unique scope of engineering application conditions. For example, generally under good hard soil geological conditions, caisson technology may not be used, but it is more convenient and economical to use other foundation pit construction techniques. However, in soft soil areas, due to loose geology, high groundwater level, and poor stability, the foundation pit support structure using general non-caisson technology will lead to high support costs, and at the same time l...
