Description

A split and combined pouch sealing device

technical field

The utility model relates to a grouting and sealing device, in particular to a grouting and sealing device which is suitable for drilling and sealing holes in underground gas drainage in coal mines.

Background technique

At present, the sealing technologies commonly used in China mainly include mechanical sealing, polyurethane-based organic material sealing and cement-based inorganic material sealing, but the sealing success rate and gas drainage efficiency are low. In recent years, European and American countries have carried out technical research on the "injection pipe sealing method", which has significantly improved the success rate of hole sealing and the efficiency of gas drainage, but the cost is very high. Therefore, there is a need for a sealing device with low cost, easy operation and good sealing effect.

Contents of the invention

The purpose of the utility model is to overcome the deficiencies in the prior art and provide a sealing device with low cost, easy operation and good sealing effect.

In order to achieve the above purpose, the utility model's split combined bag sealing device includes a grouting pipe, a grouting pipe and a PVC pipe arranged in the borehole, and the two sides of the PVC pipe are respectively set with cotton hemp bags Bag B and cotton burlap bag A, the grouting pipe passes through the cotton burlap bag B and enters the cotton burlap bag A, and the grouting pipe is respectively provided with three-way one-way on the pipe section at the position of the two cotton burlap bags The valve, the grouting pipe is located on the pipe section between the two cotton sacks and is provided with a blast valve for injecting high water expansion material into the borehole. The grout return pipe is fixed and sealed with the cotton sack B through the sealing ring. The grouting pipe is fixed and sealed with the cotton sack bag A through the sealing ring.

The grouting pipe is provided with a plurality of quick connectors on the pipe section between the two cotton burlap bags.

The front portion of the PVC pipe is connected with a flower pipe.

Beneficial effects: the hole sealing device of the utility model is simple in structure and easy to operate. It can prevent the hole from collapsing by sending the pipe first, prevent a large amount of gas from gushing out in the hole, and effectively decompose the device to facilitate the operation of the workers. Pneumatic stirring and grouting integrated pump is used for grouting, which improves work efficiency, reduces labor intensity, is convenient for connection and disassembly, and can adjust the length of the sealing hole according to the actual drilling situation, which is very practical.

detailed description

An embodiment of the present utility model is further described below in conjunction with accompanying drawing:

As shown in Figure 1, the split combined bladder bag sealing device of the present utility model is mainly composed of a grouting pipe 1, a grout return pipe 2, a PVC pipe 4 and a cotton hemp bag arranged in the borehole 3; The front portion of the PVC pipe 4 is connected with a flower pipe 5. Both sides of the PVC pipe 4 are respectively fitted with cotton burlap bags B9 and cotton burlap bags A10, the grouting pipe 1 passes through the cotton burlap bag B9 and enters the cotton burlap bag A10, and the grouting pipe 1 is located at the two sides. A three-way check valve 6 is respectively provided on the pipe section at the position of the two cotton burlap bags, and a blast valve 7 for injecting high water-swellable material into the borehole is provided on the pipe section between the two cotton burlap bags. , the grout return pipe 2 is fixed and sealed with the cotton bag B9 through the sealing ring 11, and the grouting pipe 1 is fixed and sealed with the cotton bag A10 through the sealing ring 11. The grouting pipe 1 is provided with a plurality of quick connectors 8 on the pipe section between the two cotton burlap bags.

As shown in Figure 2, there are five parts at the B9 position of the cotton bag, namely the grouting pipe 1, the bag, the sealing ring 11, and the three-way check valve 6, and the grouting pipe 1 and the grouting pipe 2 adopt the sealing ring 11 is fixed and sealed with the pouch.

As shown in Figure 3, the position of the cotton pouch A10 includes four parts, namely the grouting pipe 1, the pouch, the sealing ring 11, and the three-way check valve 6, and the grouting pipe 1 is fixed with the pouch by the sealing ring 11 seal.
