Embodiment Construction

[0014] The present invention will be described in detail below in conjunction with accompanying drawing:

[0015] Such as figure 1 , figure 2 As shown, the sprayed reinforced concrete lattice beams in slope treatment mainly include longitudinal lattice beams 1, transverse lattice beams 2, anchor rods anchored into lattice beams 3, and anchor rods 4

[0016] The specific implementation steps are as follows:

[0017] a. Leveling of the side slope: According to the design requirements, level the slope surface that needs to be treated;

[0018] b. Construction of lattice beam anchors: the construction of anchors can be done manually or mechanically. After the anchors are implanted and grouted, the anchors need to be anchored into the transverse lattice beams (2) and longitudinal lattice beams (1) );

[0019] c. Lattice beam construction: Bind the steel bars of the transverse lattice beam (2) and the longitudinal lattice beam (1) according to the design requirements, and suppo...

Abstract

The invention discloses a concrete pouring method for reinforced concrete lattice beams in slope treatment. The concrete pouring method comprises the following steps: a. leveling of a slope surface: leveling the surface of a slope required to be treated; b. construction of a lattice beam anchor rod: carrying out anchor rod construction in a manual or mechanical hole making manner, and carrying out grouting after the anchor rod is implanted, wherein the anchor rod is required to be anchored into a transverse lattice beam (2) and a longitudinal lattice beam (1); c. construction of the lattice beams: binding reinforcing steel bars of the transverse lattice beam (2) and the longitudinal lattice beam (1), and erecting molding boards; and d. concrete construction of the lattice beams: uniformly mixing cobbles, cement, graded sand and other building materials drily according to a certain proportion to obtain a dry mixture, conveying the dry mixture to nozzles via compressed air, mixing the dry mixture with pressure water, and carrying out spray irrigation. The concrete pouring method has the advantages of low requirement on construction site conditions, simple mechanical equipment, low construction cost, high construction efficiency and reliable quality, and is applicable to slopes of various side angles.

Description

technical field [0001] The invention relates to a construction method of lattice beams in slope treatment, which can effectively improve the construction speed and quality of lattice beams, save labor and mechanical workload, and is suitable for large slope angles slope. Background technique [0002] Lattice protection is a commonly used slope treatment method. This method can be combined with biological slope protection method, so that it can not only overcome the serious soil erosion, landslide, debris flow and other disasters caused by the slope, but also maintain ecological balance. At present, in lattice protection, masonry masonry lattice and reinforced concrete lattice are mostly used, but in the construction of reinforced concrete lattice, concrete pouring has always been a difficult problem in the construction of this project. Generally, the amount of concrete that can be poured in a short period of time is small, and most of the concrete pouring locations are far ...
