Description
Technical field
The present invention relates to gas drainage holes hole-sealing groutings in a kind of tunnel to pump improved equipment, belongs to well gas drainage technology neck
Domain.
Background technique
Highly gassy mine now mostly use gas drilling in advance in advance take out, CO2The controlling measurements lanes such as gas phase pressure break, gas relief hole
Gas emission in road tunneling process.The sealing quality of gas drilling directly affects watt during gas drilling is taken out in advance in advance
The effect of this extraction, gas sealing of hole mostly uses the grouting pump of 2ZBQ150/6 model at this stage, this grouting pump quality 83kg, maximum
Grouting pressure is 0.6mpa.Since gas drilling construction place is more during highly gassy mine roadway construction, grouting pump is made
For small-sized extraction equipment it is that save the cost tends not to meet every bench drill machine and is equipped with a grouting pump, but by shared nearby
Mode uses.
The grouting pump of 2ZBQ150/6 model is time-consuming and laborious in the handling process due to heavier mass.
Summary of the invention
Innovation transformation is carried out to grouting equipment for site operation situation, the labour reduced in grouting pump handling process is strong
Degree provides stable grouting pressure, improves slip casting efficiency, increases economic efficiency, and realizes cost efficiency.
The present invention is realized by following technical scheme:
Gas drainage holes hole-sealing grouting pumps improved equipment, including BQG200/0.2 coal mine pneumatic diaphragm pump in a kind of tunnel；It should
BQG200/0.2 coal mine is with the pulp-absorbing pipe in pneumatic diaphragm pump to carry out pumping to slip casting liquid；By inciting somebody to action diaphragm pump air feed
Slurries extraction；The BQG200/0.2 coal mine is equipped with pressure port with pneumatic diaphragm pump, by connection pressure gauge come real-time monitoring note
Starch pressure value.
Further, grouting pressure is stablized in 1.3mpa.
Gas drainage holes hole-sealing grouting pumps modification method in a kind of tunnel, and grouting pump uses BQG200/0.2 coal mine pneumatic
Diaphragm pump carries out pumping to slip casting liquid, mixes injecting paste material in fixed container by grouting pump and adds water adjustment certain viscous
Slurries are infused by grout outlet by extracting slurries out to diaphragm pump air feed and realize slip casting operation in Grouting Pipe by the liquid of consistency.
Further, the BQG200/0.2 coal mine is equipped with pressure port with pneumatic diaphragm pump, by connection pressure gauge come in real time
Monitor grouting pressure value.
Further, grouting pressure is stablized in 1.3mpa.
The invention has the advantages that:
Slip casting operation is carried out with pneumatic diaphragm pump using BQG200/0.2 coal mine, grouting pressure is stablized in 1.3mpa.By test
Hole-sealing grouting operation is carried out using starting diaphragm pump, gas drilling sealing of hole effect is good, realizes efficient sealing of hole.

As label indicate same or similar element or element with the same or similar functions.Described embodiment is the present invention
A part of the embodiment, instead of all the embodiments.The embodiments described below with reference to the accompanying drawings are exemplary, it is intended to use
It is of the invention in explaining, and be not considered as limiting the invention.Based on the embodiments of the present invention, ordinary skill people
Member's every other embodiment obtained without making creative work, shall fall within the protection scope of the present invention.Under
Face is described in detail the embodiment of the present invention in conjunction with attached drawing.
As shown in Figure 1 and Figure 2, gas drainage holes hole-sealing grouting pumps improved equipment, including BQG200/0.2 coal in a kind of tunnel
Mine pneumatic diaphragm pump 1；The BQG200/0.2 coal mine is with the pulp-absorbing pipe 2 in pneumatic diaphragm pump 1 to take out to slip casting liquid 3
Note；By the way that slurries are extracted out to diaphragm pump air feed；The BQG200/0.2 coal mine is equipped with pressure port with pneumatic diaphragm pump 1, passes through
Connection pressure gauge 4 carrys out real-time monitoring grouting pressure value.
Grouting pressure is stablized in 1.3mpa.
Gas drainage holes hole-sealing grouting pumps modification method in a kind of tunnel, and grouting pump uses BQG200/0.2 coal mine pneumatic
Diaphragm pump carries out pumping to slip casting liquid, mixes injecting paste material in fixed container by grouting pump and adds water adjustment certain viscous
Slurries are infused by grout outlet by extracting slurries out to diaphragm pump air feed and realize slip casting operation in Grouting Pipe by the liquid of consistency.
The BQG200/0.2 coal mine is equipped with pressure port with pneumatic diaphragm pump, by connection pressure gauge come real-time monitoring slip casting
Pressure value.
Grouting pressure is stablized in 1.3mpa.
The grouting pump quality that slip casting in the past uses is heavy, easily blocking, grouting pressure is unstable, ZBQ150/6 type grouting pump quality
