Embodiment

[0016] like figure 2 As shown, a cutting, soil taking and grouting integrated casing, the construction steps are as follows:

[0017] A. When the construction is turned down, the tooth mouth 3 cuts the soil,

[0018] B. After reaching the drilling depth, the grab bucket 4 is put away,

[0019] C. Lift the inner casing 2, take out the soil,

[0020] D. Carry out operations such as lowering the core material, pouring concrete, etc., or carry out spraying reinforcement through the spraying pipe hole 5,

[0021] E. After the initial setting, lift the outer layer pipe 1 to complete the construction. After the outer layer pipe 1 and the inner layer pipe 2 are locked and connected, move to the next place for construction.

Abstract

The invention relates to a cutting, soil taking and grouting integrated sleeve pipe which is composed of an outer layer pipe and an inner layer pipe. The lower portion of the outer layer pipe is provided with a tooth port which can cut soil when rotated downwards, different types of tooth ports such as cutting teeth and grinding teeth can be selected according to geological conditions, the outer layer pipe and the inner layer pipe are connected in a buckled mode and can be separated, the lower portion of the inner layer pipe is provided with a grabbing hopper which can be closed in a grabbingmode, and the inner side of the outer layer pipe is provided with grout (liquid) jet holes capable of jetting grout or water. Soil can be cut when the sleeve pipe is rotated downwards, soil can also be taken out at the same time, slag removal is not needed, then, a series of operations of grout (liquid) jetting are carried out, the construction efficiency is improved, and the integrated sleeve pipe is novel and efficient.

Description

technical field [0001] The invention relates to underground construction machinery, in particular to a casing. Background technique [0002] Casing is generally used in underground engineering construction, and is usually used to protect pipe pile construction or to help hole forming process to prevent hole collapse. This technique is often used to take soil from hard soil layers for pipe pile construction or muddy soil layers to prevent hole collapse. Now, with the increase of building density, the protection effect of casing construction on the surrounding environment is gradually being paid attention to. The latest casing construction machinery has entered the field of underground construction. The traditional casing is mainly used for hole forming and protection, and has a single function. Therefore, the present invention provides an integrated casing for cutting, soil extraction and grouting. It can be quickly grouted, which speeds up the construction efficiency. It i...
