Embodiment Construction

[0037] The present invention will be further described in detail below with reference to the accompanying drawings.

[0038] The invention discloses a caisson construction method, comprising the following steps:

[0039] S1. Lift the well pipe 2 through the lifting device 3: the lifting device 3 includes a moving frame 31, a roller 32 installed at the bottom of the moving frame 31, and a handrail 33 installed at the top of the moving frame 31; The first winch 34, each first winch 34 includes a first steel strand 341, and the end of the first steel strand 341 away from the first winch 34 is fixed with a lifting lug 342; Then, the lifting lugs 342 are threadedly connected with the threaded holes, and then the first hoist 34 is started, and the well pipe 2 can be lifted at this time;

[0040] S2. Grinding the obstacles by the grinding device 4: a second winch 35 is installed on the top of the moving frame 31, the second winch 35 includes a second steel strand 351, and the grindi...

Abstract

The invention relates to an open caisson construction method. The open caisson construction method comprises the following steps that firstly, an elevating device is used for lifting a well pipe and comprises a movable frame, wheels and a handrail; secondly, a grinding device is used for grinding an obstacle, a second winch is arranged on the top of the movable frame and comprises a second steel strand, the grinding device comprises a rack and a grinding mechanism, when the obstacle in an open caisson needs to be ground, the second winch is started firstly, then, the rack can be placed to thebottom of the open caisson, and then the grinding mechanism is used for grinding the obstacle; thirdly, the grinding device is moved out, the second winch is started, and accordingly the grinding device can be moved out; fourthly, the well pipe is loosened, a lifting lug and the well pipe are separated by rotating the lifting lug, then, a first winch is used for making the lifting lug and the wellpipe separated, and accordingly the well pipe can be loosened; and fifthly, soil excavation continues, and the steps from the first step to the fourth step are repeatedly conducted if the obstacle isencountered in the soil excavation process. By means of the open caisson construction method, the possibility of well pipe damage can be reduced.

Description

technical field [0001] The invention relates to the technical field, in particular to a caisson construction method. Background technique [0002] In mine construction, the caisson construction method is often used. The so-called caisson construction method means that the caisson body is first made on the ground or pit, that is, the caisson member body with openings and made of reinforced concrete is made. Layers of soil are excavated and soil moved. As the soil level in the well gradually decreases, the caisson body overcomes the frictional resistance with the soil wall by virtue of its own weight, and sinks continuously to reach the predetermined construction design position. [0003] However, during the construction of the caisson, because the construction is usually carried out according to the previous geological exploration report, and sometimes the preparation for the possible subsidence difficulties is insufficient, when the caisson body reaches a certain distance b...
