High-water-pressure soil layer anchor cable supporting construction method

Abstract

The invention discloses a high-water-pressure soil layer anchor cable supporting construction method. The high-water-pressure soil layer anchor cable supporting construction method comprises the following steps that S1, site investigation is conducted, specifically, the site investigation is conducted on a site, site construction safety is guaranteed, gas pipelines and optical cable lines in a wall are removed, a water supply and power supply site capable of meeting construction requirements is established, a clean and barrier-free construction road is cleaned out, and safety signs are arranged around the site; and S2, drilling operation is conducted, specifically, a drilling machine enters the site and stays at the flat position, if the position is uneven, leveling is conducted, the operation stability of the drilling machine is ensured, a pile casing is buried at the drilling position, and drilling is conducted. The manual labor intensity is effectively reduced, the construction convenience is improved, and the process level is high, so that the installation method of an anchor cable is quick and convenient, has the advantages of stability and high strength, is high in safety and reliability, can be widely popularized, has the effects of high sealing performance and long service life, and effectively improves the adaptability of the anchor cable.

Description

technical field [0001] The invention belongs to the technical field of foundation engineering, and in particular relates to a construction method for anchor cable support in high water pressure soil layers. Background technique [0002] Bolt support refers to a reinforcement and support method used in surface engineering such as slopes and deep foundation pits, as well as underground chambers such as tunnels and stopes. The rod column is made of metal parts, wood parts, polymer parts or other materials, and is driven into the pre-drilled holes in the surface rock mass or the rock mass around the chamber. optional), or rely on the bonding effect to combine the surrounding rock and the stable rock mass to produce suspension effects, composite beam effects, and reinforcement effects, so as to achieve the purpose of support. It has the advantages of low cost, good support effect, simple operation, flexible use, and less construction clearance. [0003] At present, anchor cable...

Problems solved by technology

[0003] At present, anchor cable support is a support method that uses anchor cables and metal mesh for joint support. It is a relatively new support technology. In terms of bearing capacity, support for large-span sections and For the support of the roof fall area, compared with the conventional support, the anchor cable support technology has great advantages. However, the existing construction process is relatively complicated when the anchor cable support construction is carried out on the site. Many, slow work efficiency, unable to meet the needs of enterprises
