Problems solved by technology

[0002] At present, anchor rods are often used for anchoring in various support processes, so as to improve the anchoring force of the overall support, including the use of grouting anchor rods, which are hollow rods with holes at their ends , so that the grout overflows into the soil layer, thereby further improving the overall anchoring force. When configuring the sealing structure of the grouting anchor, it is often impossible to improve the sealing effect and grouting effect due to the relatively simple sealing structure. Monitoring of slurry pressure

Embodiment Construction

[0037] see Figure 1~3 , the invention provides a sealing device for monitoring the grouting pressure of a grouting bolt, comprising:

[0038] The first sealing disc 5 is movably arranged at the orifice position of the grouting hole 1, so that the grouting hole 1 is sealed after the grouting is finished, and in the first sealing disc 5 A plurality of first grouting anchor rods 2 are arranged through the sealing slide;

[0039] The second sealing disk 6 is fixed in the reaming 3, so that the reaming 3 is sealed during the grouting process;

[0040] The reaming hole 3 is arranged at the orifice position of the grouting hole 1, and the diameter of the reaming hole 3 is larger than the diameter of the grouting hole 1;

[0041] The first grouting anchor 2 is pulsed by a pulsed grouting component 8 .

[0042] That is to say, in the implementation process, the second sealing disc 6 can be used to seal the reaming hole 3 during the grouting process, and the first sealing disc 5 is ...

Abstract

The invention discloses a hole sealing device for monitoring the grouting pressure of grouting anchor rods. The hole sealing device comprises a first hole sealing disc and a second hole sealing disc, wherein the first hole sealing disc is movably arranged at the hole opening position of a grouting hole so that the grouting hole can be sealed after grouting is finished, and the multiple first grouting anchor rods are arranged in the first hole sealing disc in a sealed and sliding penetrating mode; the second hole sealing disc is fixed in a reamed hole so that the reamed hole can be sealed in the grouting process; the reamed hole is formed in the hole opening position of the grouting hole, and the diameter of the reamed hole is larger than that of the grouting hole; and the first grouting anchor rods are subjected to pulse slurry supply through a pulse slurry supply assembly.

Description

technical field [0001] The invention relates to the technical field of hole sealing of grouting anchor rods, in particular to a hole sealing device for monitoring the grouting pressure of grouting anchor rods. Background technique [0002] At present, anchor rods are often used for anchoring in various support processes, so as to improve the anchoring force of the overall support, including the use of grouting anchor rods, which are hollow rods with holes at their ends , so that the grout overflows into the soil layer, thereby further improving the overall anchoring force. When configuring the sealing structure of the grouting anchor, it is often impossible to improve the sealing effect and grouting effect due to the relatively simple sealing structure. For the monitoring of slurry pressure. [0003] Therefore, it is necessary to provide a sealing device for monitoring the grouting pressure of the grouting anchor to solve the above problems. Contents of the invention [...
