Recoverable side slope temporary protection structure and construction method thereof

Abstract

The invention discloses a recoverable side slope temporary protection structure which comprises a grid panel laid along the surface of a side slope. Concrete pressing tops are poured to the top part and the bottom part of the grid panel; preformed holes are uniformly distributed in a side slope soil body; hollow steel pipes with sharp anchor-shaped head parts are arranged in the preformed holes; cement pastes are fully pressure-injected into inner cavities of the hollow steel pipes; the cement pastes are fully injected into clearances of the preformed holes through through holes formed in hollow steel pipe walls; the tail parts of the hollow steel pipes extend to penetrate through the grid panel and are then connected with a pressure welding steel plate in a sleeving way; the pressure welding steel plate is fixed through screwing nuts; a steel wire rope net covering the grid panel is arranged under the pressure welding steel plate; and steel wire ropes forming the steel wire rope net are connected with the hollow steel pipes in a winding way. The invention discloses a construction method of the recoverable side slope temporary protection structure at the same time. According to therecoverable side slope temporary protection structure and construction method thereof provided by the invention, the construction speed can be effectively improved, the construction quality is improved, and the construction cost is reduced.

Description

technical field [0001] The invention relates to the technical field of soil road cutting excavation slope protection, in particular to a recyclable temporary slope protection structure and a construction method thereof. Background technique [0002] In order to ensure construction safety, during the process of grading and excavating foundation pits during the construction of the subway, it is necessary to implement temporary protection on the slope to ensure the stability of the slope. The traditional temporary protection of slopes generally adopts the method of spraying concrete, using mixing equipment and high-pressure conveying devices for pouring. Due to the large construction scope and the use of more concrete materials, it is often impossible to invest more manpower and material resources. Meet the requirements of the construction schedule. Secondly, the process of spraying concrete is more polluting to the environment, and the concrete material cannot be recycled and...

AI Technical Summary

Problems solved by technology

The traditional temporary protection of slopes generally adopts the method of spraying concrete, using mixing equipment and high-pressure conveying devices for pouring. Due to the large construction scope and the use of more concrete materials, it is often impossible to invest more manpower and material resources. Meet the requirements of the construction progress

Secondly, the process of spraying concrete is more polluting to the environment, and the concrete materials cannot be recycled and reused after use, so a large amount of construction waste will be generated, which is not conducive to environmental protection
