Embodiment 1

[0033] A network grouting device, including a grouting pipeline and a connecting head, the grouting pipeline includes a grouting main pipe 1 and an arc-shaped grouting pipe 2 arranged axially along the roadway 14, and one end of the arc-shaped grouting pipe 2 It is connected with the grouting main pipe 1 through the connecting head, and the arc-shaped grouting pipe 2 is distributed with a plurality of connecting heads in a circle. 8 corresponds and is flexibly connected, the beginning of the grouting main pipe 1 is connected with the grouting pump 3, and the end is sealed.

[0034]The 90° two-way joint 10, the T-shaped three-way joint 9, the four-way joint 11, and the joint use of various joints further optimize the structure of the present invention, reduce unnecessary grouting pipelines, and save costs .

[0035] Specifically, such as Figure 1-2 As shown, the present invention includes a grouting pipeline and a connecting head for pipeline connection. Both the main grouti...

Embodiment 2

[0037] On the basis of the above-mentioned embodiments, a first cut-off valve 4 is provided on the grout supply pipeline between the grouting pump 3 and the grouting main pipe 1, and a plurality of second stop valves are arranged on the grouting main pipe 1 at intervals 5. The second cut-off valve 5 is located between the two arc-shaped grouting pipes 2. A third cut-off valve 6 is provided at the connection between the arc-shaped grouting pipe 2 and the main grouting pipe 1. The arc-shaped grouting pipe 2 and the The pipeline connection of the grouting anchor rod 8 is provided with a fourth cut-off valve 7 .

[0038] Specifically, such as figure 1 As shown, a first cut-off valve 4 is installed on the grout supply pipeline between the grouting pump 3 and the main grouting pipe 1 to control the amount of grout input into the main pipe 1. If there is an abnormality in the grouting pipeline, It can be used to stop the input of grout, and multiple second cut-off valves 5 are insta...

Embodiment 3

[0040] On the basis of the above embodiments, a one-way valve 13 is provided on the connecting pipeline between the fourth cut-off valve 7 and the grouting anchor rod 8 , and the one-way valve 13 is threadedly connected with the grouting anchor rod 8 .

[0041] Specifically, such as figure 2 As shown, a one-way valve 13 is installed on the connecting pipeline between the fourth shut-off valve 7 and the grouting anchor rod 8. The one-way valve 13 can effectively prevent grouting. The one-way valve 13 and the grouting anchor rod 8 Thread matching connection is adopted between them, which is convenient for installation and disassembly, and improves working efficiency. A variable head can also be installed between the one-way valve 13 and the grouting anchor rod 8. The variable head is a joint with different diameters at both ends, so as to facilitate different connections. As for the fittings of diameter, one end of the variable head matches the outlet of the one-way valve 13, a...

Abstract

The invention discloses a network grouting device and a use method thereof. The network grouting device comprises grouting pipelines and connecting junctions. The grouting pipelines comprise a main grouting pipe and arc-shaped grouting pipes which are arranged in the axial direction of a roadway. One end of each arc-shaped grouting pipe is connected with the main grouting pipe through the corresponding connection junction. Multiple connecting junctions are annularly distributed on each arc-shaped grouting pipe. The distribution positions of the connecting junctions on each arc-shaped groutingpipe correspond to grouting anchor rods in the roadway and are detachably connected. The start end of the main grouting pipe is connected with a grouting pump, and the tail end of the main grouting pipe is sealed. The network grouting device is simple in structure and convenient to operate, the grouting pipelines are few, power of the grouting pump can be guaranteed, the number of grouting holes is not limited, and grouting efficiency is greatly improved.

Description

technical field [0001] The invention relates to a mine rock mass grouting device, in particular to a network grouting device and a using method thereof. Background technique [0002] As the mining of mines gets deeper and deeper, the underground pressure is also increasing, which makes it difficult to support the surrounding rock of the roadway. In recent years, the effect of strengthening the surrounding rock by grouting is obvious, but the efficiency of single-hole grouting is basically Low, unable to keep up with the roadway excavation speed, which affects the construction progress; there are also multi-hole grouting, although the number of holes for simultaneous grouting has increased, but there are also many grouting pipes used, which are easy to block the pipeline. Simultaneous grouting The number of holes is also limited, and the grouting process has many influences, and it is inconvenient to use and wastes materials. Contents of the invention [0003] The purpose ...
