Embodiment Construction

[0026] The present invention will be further explained below in conjunction with the drawings.

[0027] Such as figure 1 As shown, the present invention includes an upper metal positioning plate 2, a lower metal isolation plate 3, a rubber body 10, an air bag exhaust pipe 11, a drilled exhaust pipe 12, and a grouting pipe 13, wherein the upper metal positioning plate 2, the lower metal isolation The central area of ​​the plate 3 and the rubber body 10 is provided with an anchor rod (anchor cable) hole 14, an upper metal positioning plate 2, a lower metal isolation plate 3, an airbag exhaust pipe 11, a drilled exhaust pipe 12, a grouting pipe 13 and The positional relationship of the anchor rod (anchor cable) hole 14 is as follows Figure 4 , Figure 5 .

[0028] Such as figure 1 , figure 2 As shown, the main part of the stop grout plug has a rubber body 10 as a whole. There is an airbag 4 inside the rubber body 10, and a rubber sleeve 8 used to prevent the grout from overflowing a...

Abstract

The invention discloses a grouting-stopping plug for an anchor rod (anchor cable), which mainly comprises an upper metal positioning plate (2), a lower metal isolating plate (3), a rubber body (10), an air bag exhaust pipe (11), a drilling exhaust pipe (12) and an injection pipe (13), wherein core regions of the upper metal positioning plate (2), the lower metal isolating plate (3) and the rubberbody (10) are provided with anchor rod (anchor cable) holes (14), an air bag (4) is arranged inside the rubber body (10), and the bottom of the rubber body (10) is provided with a rubber jacket (8) used for preventing grouting-stopping liquid from overflowing along the anchor rod (anchor cable). The grouting-stopping plug and system has the advantage that the defect of poor grouting-stopping effect or even complete ineffectiveness caused by connection degumming among all parts, cover shedding, abrasion, air bag eversion and the like in the traditional grouting-stopping plug is fundamentally overcome due to the integral rubber body (10) which is used as the main body of the grouting-stopping plug, the design is reasonable and economic, the structure is simple, the installation and operation is convenient, the leakproofness is reliable and the grouting-stopping effect is good.

Description

Technical field [0001] The invention relates to a grout stopper for an anchor rod (anchor cable), which is used for rock and soil anchoring projects such as mines and side slopes. It is fixed in a borehole during grouting to prevent slurry from overflowing. It is an anchor rod (anchor cable) The grouting device used in grouting operation. Background technique [0002] The application of anchor rod (anchor cable) in geotechnical engineering has a history of nearly a hundred years, and its engineering practice experience and corresponding theoretical research are also becoming mature and perfect. In recent years, prestressed anchorage has become increasingly popular in rock mass reinforcement, but it also brings some urgent problems to be solved. From the structure of rock and soil reinforcement anchor (anchor cable), it can be seen that: ) Consists of three parts: inner anchor section, working section and tension end. It can be seen from the force state that the inner anchor sec...
