Problems solved by technology

Therefore, bolts are widely used in underground foundation treatment and slope reinforcement and support, which are characterized by a large number, dense arrangement, and cumbersome detection, which adds a lot of difficulty to the construction
[0003] After the construction of the anti-floating anchor, the anti-floating anchor needs to be tested for the pull-out bearing capacity of the steel bars in the anchor. The traditional testing process is to cut off the 90-degree hook steel bar at the upper end of the anchor bar for testing. After completion, it is necessary to use a new steel bar of the same specification and type for welding with the anchor rod. This method requires a lot of work, requires high quality welding hooks, and takes up a long construction time for inspection. How to speed up the inspection time has become an urgent problem for those skilled in the art. key issues

Embodiment Construction

[0044] The following is attached Figure 1-2 The application is described in further detail.

[0045] The embodiment of the present application discloses a non-destructive testing device for an anti-floating anchor. refer to figure 1 , a kind of non-destructive testing equipment for anti-floating anchors, including the main reinforcement 1 of the anchor rod to be tested installed on the ground, and the upper end of the main reinforcement 1 of the anchor rod has a 90-degree hook steel bar 11; the main reinforcement 1 of the anchor rod is provided with a The supporting detection mechanism 2 for the detection of the pull-out bearing capacity of the main reinforcement 1.

[0046] refer to figure 1 The jacking detection mechanism 2 includes a jack 21 arranged on the upper side of the main reinforcement of the anchor rod 1. The jack 21 is vertically arranged with the horizontal plane. Pressure gauge (not shown in the figure); a support assembly 22 for supporting the jack 21 is arr...

Abstract

The invention relates to nondestructive testing equipment for an anti-floating anchor rod and a construction method. The equipment comprises a to-be-tested anchor rod main rib, the anchor rod main ribis sleeved with a load steel plate, the load steel plate is fixed to the anchor rod main rib through an anchor bolt, force transmission steel bars are arranged on the two sides of the load steel plate, and a jacking detection mechanism used for jacking the force transmission steel bars is arranged on the upper sides of the force transmission steel bars. The method has the effects of shortening the detection time of the anti-floating anchor rod and reducing the detection damage of the anti-floating anchor rod.

Description

technical field [0001] The application relates to the field of building engineering construction, in particular to a non-destructive testing device and construction method for an anti-floating anchor rod. Background technique [0002] At present, one end of the anti-floating anchor tension member is anchored on the building floor, and the other end is anchored in the bearing layer of the foundation. The force process is firstly to transmit the uplift force to the On the grouting body; then through the friction between the grouting body and the surrounding soil layer, the force received by the grouting body is transmitted to the surrounding stable soil, thereby forming an anti-floating anchor rod with a certain pull-out resistance, which acts as an anti-floating bolt. To the anti-floating effect of the anti-floating anchor rod. Therefore, bolts are widely used in underground foundation treatment and slope reinforcement and support, which are characterized by a large number, ...
