Embodiment Construction

[0027] The invention will be described in detail below with reference to the accompanying drawings and specific examples.

[0028] This embodiment proposes a loose formation reinforcement device and its construction method, such as figure 1 As shown, including a plurality of reinforcing assemblies 20 disposed on the slope surface 11 in the loose floor 10, each of the reinforcing assembly 20 includes a hole cavity 21 disposed in the slope surface 11 and is built into the loose formation 10, in the hole cavity 21. A rigid member 22 and a nozzle 23 are provided, and the slurry body is perfuse the slurry in the hole cavity 21 to extrud the soil layer of the loose formation 10, and the reinforcement layer 24 ring is formed to be loose. Floor 10. By taking a reinforcing assembly 20 having a high degree of deformation over the side slope surface 11, a plurality of support members are formed on the loose floor 10 to quickly and safely increase the fixed strength of the side slope surface ...

Abstract

According to the loose stratum reinforcing device and the construction method thereof, the loose stratum reinforcing device comprises a plurality of reinforcing assemblies arranged on the side slope face in a loose stratum, each reinforcing assembly comprises a hole cavity formed in the side slope face and arranged in the loose stratum, and a rigid piece and a spray pipe are arranged in each hole cavity; and slurry is poured into the hole cavity through the spraying pipe so as to extrude the loose stratum, and a reinforcing layer annularly arranged on the rigid piece is formed so as to reinforce the loose stratum. The structure is particularly suitable for loose stratum foundation pit slope supporting operation, a traditional drilling and grouting type rigid piece wall is effectively improved, the using effect under the loose stratum condition can be met, the loose stratum foundation pit slope supporting operation efficiency is improved, the structure is simple, construction is safe and reliable, cost is effectively saved, and the construction period is effectively shortened; the required materials can be obtained locally, waste is avoided, and the green construction concept is met.

Description

Technical field [0001] The present invention belongs to the technical field of civil engineering foundation pit support project, in particular, to a loose formation reinforcement device and a construction method thereof. Background technique [0002] With the continuous development of my country's construction industry, whether it is in the early stages of design or construction implementation, consider the support form of foundation pit, which determines whether the actual construction is safe and reliable and whether it is economically saving resources to achieve economic benefit. In recent years, it has been used in more and more projects that meet the above requirements of the rigid part wall. Its construction is simple and cost, but there is a certain requirement for soil, such as geological conditions, rigid parts walls. The support will not meet the actual support requirements, and the reinforcement device and the construction method of the support form of the rigid parts ...
