Abstract

The invention discloses a grouting pipe which comprises a grouting pipe body. A plurality of inwards-concave parts are formed in the pipe wall of the front portion of the grouting pipe body, and at least one grout injecting hole is formed in each inwards-concave part. By means of the manner, the grouting pipe is simple and reasonable in structure and suitable for a pipe driving grouting method, the grouting holes are not liable to be blocked, grouting is smooth, and effects are good.

Description

technical field

[0001] The invention relates to the technical field of grouting construction, in particular to a grouting pipe. Background technique

[0002] In the process of building construction and road maintenance, soft soil and road subgrade are often reinforced. As a relatively mature engineering technology, grouting technology has been widely used. The basic principle of grouting is that grout is compressed under pressure. Into the cracks, pores or cavities of formations or structures to improve their integrity and compactness.

[0003] Grouting pipes are generally used in the grouting process. Based on the advantages of low cost and the fact that the grout will not rise along the borehole, the pipe-piercing grouting method (directly driving the grouting pipe into the soil) is widely used. The existing The grouting hole on the grouting pipe used for pipe grouting is easy to be blocked, and the soil and sand are not easy to discharge after entering the grouting pipe,...
