Abstract
The invention relates to an underground gushing water aggregate addition system and a process thereof. In the invention, aggregate can be smoothly and continuously injected into a borehole under the high-pressure gushing water condition to block up bigger guide water-contained fractures or overflow structures so as to drag the flow rate of gushing water, promote the materials to be settled and solidified and reduce the material loss, thereby achieving the goal of grouting to plug the water. The system comprises a grouting pipe. The grouting pipe is respectively communicated with a grouting casing pipe through a water injection pipeline I and a water injection pipeline II; the grouting casing pipe is provided with a sluice valve I and a sluice valve II; the joints of the water injection pipeline I and the grouting casing pipe are at the front end of the grouting casing pipe and the front part of the sluice valve I, and the joints of the water injection pipeline II and the grouting casing pipe are arranged between the sluice valve I and the sluice valve II, i.e. the water injection pipeline I and the water injection pipeline II are divided into two independent water injection systems through the sluice valve I.

Embodiment:
The top board water yield is big near the auxilliary two main haulage roadway F1 tomographies in the solid colliery of dragon, and the tunnel domestic demand is taken anti-fluid barrier pedestrian, vehicle could pass through.In top board trickle grouting for water blocking engineering construction process, lead to the boring of fault zone in the 3# chamber: the 3-2 hole is at the water yield 130m of 58m place
3/ h, 3-3 hole are at the water yield 70m of 43m place
3/ h; 4# chamber (in the sump) leads to the boring of fault zone: the 4-6 hole is at the water yield 120m of 69m place
3/ h, 4-7 hole are at the water yield 135m of 79m place
3/ h.Cross owing to above-mentioned 4 holes are disclosed aquaporin and water yield big, apart from top board trickle offset from reason such as near, slurries are difficult for fixed, precipitation in the slip casting process, slurries almost all run off, and can not carry out effective shutoff to crossing aquaporin.After adopting this aggregate add-on system and technology thereof subsequently, utilize the aforesaid operations step that these 4 borings are continued to inject aggregate: 3-2 hole 158kg, 3-3 hole 106kg, 4-6 hole 1152kg, 4-7 hole 163kg.Because the injection of a large amount of aggregates, the water yield that cross that aquaporin diminishes, the flow velocity of water slows down, arrives the trickle district obviously diminishes, and has played the effect in temporary transient shutoff major path, big crack, injects slurries subsequently, fully shutoff cross aquaporin, thoroughly solved the water burst in trickle district.
