Embodiment Construction

[0060] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments, but these embodiments should not be construed as limiting the present invention.

[0061] refer to Figure 1 to Figure 12 , The multi-layer nested, coaxial sequentially assembled anchor cable structure of the present invention includes an axial core layer 1, a middle frame layer 2 and an outer cladding layer 3 from the inside to the outside.

[0062] The axial layer 1 is located at the core of the overall structure of the anchor cable, including a grouting pipe 4 in the center and six inner ring anchor cable bundles 6 arranged around the grout pipe 4. Support 7 is fixed. The inner isolation bracket 7 is made of hard plastic, and its shape is similar to a ring structure of a gear. For ease of description, the gear term is used to describe below: the outer diameter of the gear is 70mm, the inner diameter of the gear is 27mm, and the tooth width i...

Abstract

The invention discloses a multi-layer nest and coaxial sequencing assembly type anchor cable construction and installation method. The anchor cable construction comprises an axis layer, a middle frame layer and an outsourcing layer from inside to outside. The axis layer concludes an interjection pipe in the center and an inner ring anchor cable ties disposed surround the interjection pipe. The inner ring anchor cable ties are fixed through an inboard isolation frame disposed along the axial direction. The middle frame layer comprises an out ring anchor cable ties arranged surround the axis layer. The out ring anchor cable ties is fixed by the outboard isolation frame disposed along the axial direction. The outsourcing layer comprises a corrugated pipe surround the middle frame. The periphery of the corrugated pipe is provided with an outer middle frame along the axial direction. The outer middle frame is connected with a borehole hall in a locked mode. The multi-layer nest and coaxial sequencing assembly type anchor cable construction and installation method breaks the conventional and inherent mind of whole assembly and molding of the anchor cable and pushing the cable into the hole at one time and divides the anchor cable body into three layers: the axis layer, the middle frame layer and the outsourcing layer by the modular approach. The multi-layer nest and coaxial sequencing assembly type anchor cable construction and installation method carry out a sequencing assembly to the axis layer, the middle frame layer and the outsourcing layer successively from inside to outside for decreasing the number and the weight of the anchor cable components in the construction of each sequence.

Description

technical field [0001] The invention relates to the fields of reinforcement and treatment of water conservancy and hydropower, roads, bridges, and geotechnical engineering, and is mainly applicable to building foundations, slopes and other geotechnical support and reinforcement projects, and specifically refers to a multi-layer nested, coaxial sequential assembly Type anchor cable structure and installation method. Background technique [0002] Since the anchor cable technology was introduced into our country in the 1960s, it has been widely used in many engineering fields, especially in water conservancy and hydropower. At present, anchor cables have become an important technology for the support and reinforcement of dam foundations, slopes, and underground caverns in water conservancy and hydropower projects. [0003] The anchor cable construction for geotechnical reinforcement is generally carried out according to the following construction procedures: measurement and po...
