Description

TECHNICAL FIELD

[0001] The present application relates to a system for realizing six-hole alternate grouting under the condition of three grouting pipe lines. BACKGROUND

[0002] The process of grouting hole grouting is generally as follows: constructing a grouting hole, installing a hole device, connecting a grouting pipe line with the hole device, connecting a grouting pump with the grouting pipe line, pumping slurry into the grouting pipe line through the grouting pump, and then delivering the slurry into the grouting hole through the grouting pipe line.

[0003] At present, the grouting mode is generally as follows: one pipe grouts one hole, so when the number of grouting pipe lines is greater than or equal to the number of grouting holes, the alternate grouting of grouting holes can be easily realized. However, when the number of grouting pipe lines is less than the number of grouting holes (for example, only three grouting pipe lines are laid, but six grouting holes need to be alternately grouted), in order to realize the alternate grouting of grouting holes, a soft pipe with good toughness needs to be used as a grouting pipe so that the grouting pipe can be connected back and forth between grouting holes, and a large amount of manpower and mechanical equipment need to be invested for carrying and installation, which is not economical and low in efficiency. Therefore, in order to easily realize the alternate grouting of multiple holes under the condition of limited grouting pipe lines, the system process needs to be reformed. SUMMARY

[0004] The present application aims at improving the above-mentioned problems in the prior art, i.e., the present application discloses a system for realizing six-hole alternate grouting under the condition of three grouting pipe lines.

[0017] Further, the pipe diameter of the branch pipe is 0.5-0.7 times the pipe diameter of the first main grouting pipe.

[0018] Further, the valve is one of a gate valve, a stop valve and a ball valve.

[0042] Further, the branch pipe 8 is a high-pressure rubber pipe, and the pressure-bearing capacity of the branch pipe 8 is greater than the pressure-bearing capacity of the first main grouting pipe 10, the second main grouting pipe 11 and the third main grouting pipe 12.

[0043] Further, the pipe diameters of the first main grouting pipe 10, the second main grouting pipe 11 and the third main grouting pipe 12 are the same.

[0044] Further, the pipe diameter of the branch pipe 8 is 0.5 times the pipe diameter of the first main grouting pipe 10.

[0045] Further, the valve 7 is a gate valve, and the pressure-bearing capacity of the valve 7 is greater than or equal to the pressure-bearing capacity of the branch pipe 8.

[0046] The main functions of the branch pipe are: 1, the flexibility of the branch pipe can adapt to relatively complex terrain conditions; 2, the pipe diameter of the branch pipe is smaller than that of the main pipe, so as to reduce the cross-sectional area of the slurry passing through and increase the flow rate, and the increase of the flow rate can avoid the pipe blockage caused by the precipitation of the transported medium in the slurry.

[0047] The installation and use process of the present application is as follows

[0048] Step 1: two three-way valves, two valves 7 and two branch pipes 8 are respectively prepared for the first grouting hole 1, the second grouting hole 2, the third grouting hole 3, the fourth grouting hole 4, the fifth grouting hole 5 and the sixth grouting hole 6;

[0049] Step 2: at the first grouting hole 1, one three-way valve 9 is installed for the first main grouting pipe 10 and the second main grouting pipe 11 respectively;

[0050] At the second grouting hole 2, one three-way valve 9 is installed for the first main grouting pipe 10 and the third main grouting pipe 12 respectively;

[0051] At the third grouting hole 3, one three-way valve 9 is installed for the second main grouting pipe 11 and the third main grouting pipe 12 respectively;

[0052] At the fourth grouting hole 4, one three-way valve 9 is installed for the first main grouting pipe 10 and the second main grouting pipe 11 respectively;

[0054] At the sixth grouting hole 6, one three-way valve 9 is installed on the second main grouting pipeline 11 and the third main grouting pipeline 12 respectively.

[0055] Step 3: One branch pipe 8 is led at each three-way valve 9 to connect the first grouting hole 1, the second grouting hole 2, the third grouting hole 3, the fourth grouting hole 4, the fifth grouting hole 5 and the sixth grouting hole 6 respectively. In order to prevent the grouting hole from being blocked by the backflow of grouting slurry to the branch pipe 8, a valve 7 needs to be additionally installed at the connection between the branch pipe 8 and the grouting hole.

[0056] After the above operation is completed, any two holes or three holes can be alternately grouted, for example, the first grouting hole 1, the second grouting hole 2 and the sixth grouting hole 6 are simultaneously grouted. The right outlet of the three-way valve 9 of the first main grouting pipeline 10 at the first grouting hole 1 is closed, the valve 7 at the corresponding branch hole is opened, the right outlet of the three-way valve 9 of the third main grouting pipeline 12 at the second grouting hole 2 is closed, the valve 7 at the corresponding branch hole is opened, the right outlet of the three-way valve 9 of the second main grouting pipeline 11 at the sixth grouting hole 6 is closed, and the valve 7 at the corresponding branch hole is opened. Similarly, any grouting hole can be switched in the above six adjacent grouting holes for grouting. Specific embodiment 2

[0063] 1. The diameter of the branch pipe 8 is 0.6 times the diameter of the first main grouting pipeline 10.
