Is pipe shed construction a construction technique used in tunneling? During the construction process, it is necessary to master the key points of construction techniques to better carry out the construction. The specific key points are as follows:

1. It is necessary to clarify the characteristics of pipe shed support.

Pipe sheds are generally arranged along the entire or partial perimeter of underground engineering sections, with a uniform spacing along the circumference to form a steel pipe shed. They come in cap-shaped, square, linear, and arched designs.

2. Master the pipe shed support construction technique

The construction process of pipe shed advance support mainly includes: measuring and marking hole positions; positioning the drilling machine; performing horizontal drilling; and pushing the steel pipe into the steel pipe.

3. Mastering pipe shed support methods

The circumferential spacing of the pipe shed steel tubes greatly influences the prevention of soil collapse and relaxation above. During the construction of pipe sheds, it is necessary to select a reasonable spacing based on the structural burial depth, stratum conditions, and surrounding structures. Generally, the spacing adopted is 2.0 to 2.5 times the diameter of the steel tube. The longitudinal overlap length of two pipe sheds should be greater than 3 meters. When construction is below the railway or highway, high-stiffness steel tubes should be used for continuous arrangement.
