Problems solved by technology

[0004] However, during the on-site construction process, the bolt needs to be hammered for positioning. The hammering vibration is likely to cause the mortar segregation and mortar outflow of the bolt, and in many cases, the positioning fails. The secondary positioning makes the initial setting of the mortar and the grip of the anchor Ineffectiveness makes the support system of the entire mortar bolt invalid; moreover, the hammering disturbs the unstable surrounding rock greatly, which is easy to cause the surrounding rock to collapse; in addition, the size of the wooden wedge used to block the hole is not standardized, can't play its due role
Light ones need to be reworked, and serious ones cause engineering accidents

Embodiment Construction

[0021] The specific embodiment of the invention will be further described in conjunction with the accompanying drawings.

[0022] Mortar anchor construction method, the steps are as follows:

[0023] 1. Arrange the hole position of the anchor rod 8 first, and drill the hole according to the designed position and angle, such as figure 1 shown.

[0024] 2. Connect the pipeline of the grouting pump, then wet the pipeline with water and slurry, then insert the grouting pipe 3 to the bottom of the anchor hole, slowly open the valve and start grouting, while grouting slowly according to the amount of grout Pull out the grouting pipe 3 until the grout is full.

[0025] 3. Prepare the positioning plug. The positioning plug is composed of upper and lower parts that can form a truncated cone shape. The upper part 5 of the positioning plug is a hard wedge-shaped structure. The lower part 6 of the positioning plug is made of elastic material. The lower part 6 of the positioning plug Th...

Abstract

The invention belongs to the technical field of mortar anchor construction in tunnel and underground engineering and side slope engineering, in particular to a mortar anchor constructing method. By the method, the problem that the mortar anchor constructing method has difficulty in ensuring engineering quality in the prior art is solved. The method accomplishes mortar anchor construction by usinga frustum-shaped location plug consisting of an upper part and a lower part; the upper part of the location plug has a hard wedge structure; the lower part of the location plug is made of elastic material; and a through hole is formed in the lower part of the location plug along the mortar-injecting direction. The method disclosed by the invention is low in cost, simple and easy in operation and easy in popularization; the economic benefit and social benefit of the method are outstanding in the current large-scale tunnel and underground engineering and side slope engineering; and the popularization value of the method is very high.

Description

technical field [0001] The invention belongs to the technical field of mortar anchor rod construction in tunnels, underground engineering and slope engineering, and in particular relates to a mortar anchor rod construction method. Background technique [0002] With the increasingly tight land resources, more and more traffic route planning can no longer occupy a large amount of cultivated land, so traffic projects often need to be built in mountainous areas, and tunnels or slopes are inevitably used for design and construction in engineering construction , In the field of engineering construction, the proportion of tunnel and underground engineering and slope engineering is increasing. In many tunnel and slope construction projects, it is necessary to use mortar bolts as a support system to stabilize the surrounding rock, so mortar bolt support is currently a commonly used support system in tunnel or slope engineering. [0003] The main construction method of the currently ...
