Detailed Description

The present application is described in further detail below with reference to figures 1-3.

The embodiment of the application discloses filling pipeline washs structure.

Referring to fig. 1, a filling pipeline cleaning structure includes a filling pipeline 200, a first filling retaining wall 100, a second filling retaining wall 400 and a three-way valve 300, wherein the first filling retaining wall 100 and the second filling retaining wall 400 are formed by building a plurality of bricks, and adjacent bricks are fixedly connected together by cement mortar. The first filling retaining wall 100 and the second filling retaining wall 400 are arranged in parallel at intervals, the first filling retaining wall 100 and the second filling retaining wall 400 are both arranged perpendicular to the filling roadway 500 and fixedly connected with the roadway bottom and the roadway wall of the filling roadway 500 through cement mortar, and the first filling retaining wall 100 is used for intercepting the filling roadway 500.

Referring to fig. 2, the water outlet end of the filling line 200 passes through the second filling wall 400 and the first filling wall 100 in sequence, and the filling line 200 is disposed at the bottom of the first filling wall 100. The three-way valve 300 is disposed in communication with the filling line 200, and the three-way valve 300 is disposed between the first filling wall 100 and the second filling wall 400. The first filling retaining wall 100, the second filling retaining wall 400 and the filling roadway 500 together form an accident pool 110, and a foundation pit 111 is dug and formed below the pool bottom of the accident pool 110.

When the filling line 200 is cleaned, water is injected into the filling line 200, so that the water cleans the filling line 200, and simultaneously, the water in the filling line 200 flows into the stope along the filling line 200, and the water flowing into the stope is blocked by the first filling retaining wall 100. After the filling pipe 200 is cleaned, the three-way valve 300 is operated to communicate the filling pipe 200 with the outside, so that the water blocked by the first filling retaining wall 100 flows back to the foundation pit 111 through the filling pipe 200 and settles in the foundation pit 111. Since the bottom of the foundation pit 111 is lower than the filling tunnel 500 with respect to the horizontal plane and the filling pipe 200 is disposed at the bottom of the first filling wall 100, the water blocked by the first filling wall 100 can entirely flow into the foundation pit 111. When the foundation pit 111 is full of water, the water continues to flow into the accident pool 110.

Referring to fig. 2 and 3, a water pump 410 is fixed to a side of the second filling retaining wall 400 away from the first filling retaining wall 100 by expansion screws, a water inlet pipe 411 having flexibility is installed in communication with a water inlet of the water pump 410, and a water outlet pipe 412 is installed in communication with a water outlet of the water pump 410. The mouth of the water inlet pipe 411 is fixedly connected with a filter plate 415, and the filter plate 415 is used for filtering water entering the water pump 410. One end of the water inlet pipe 411 close to the water inlet of the water inlet pipe is coaxially and fixedly connected with a balancing weight 414 and a foam board 413, the distance from the balancing weight 414 to the water inlet of the water inlet pipe 411 is smaller than the distance from the foam board 413 to the water inlet of the water inlet pipe 411, and the buoyancy of the foam board 413 is larger than the gravity of the balancing weight 414.

Referring to fig. 2, one end of the water inlet pipe 411, which is far away from the water pump 410, is arranged in the foundation pit 111, one end of the water outlet pipe 412, which is far away from the water pump 410, is arranged to communicate with the filling pipeline 200, and the water outlet pipe 412 is provided with a switch valve 416 in a communicating manner, and the switch valve 416 is used for controlling the water outlet pipe 412 to communicate with and close the filling pipeline 200.

The water inlet pipe 411 is vertically erected in the foundation pit 111 under the action of the counterweight 414 and the foam board 413, and floats up and down along with the change of the water level in the foundation pit 111. When the filling pipeline 200 is cleaned next time, the switch valve 416 is opened, so that the water outlet pipe 412 is communicated with the filling pipeline 200, the water pump 410 is started, the water pump 410 pumps the water in the foundation pit 111 into the filling pipeline 200 through the water inlet pipe 411, the water pump 410 and the water outlet pipe 412, the water in the filling pipeline 200 is pressurized, and the filling pipeline 200 is cleaned more cleanly.

The implementation principle of the filling pipeline cleaning structure in the embodiment of the application is as follows: when the filling line 200 is cleaned, clean water is injected into the filling line 200, so that the clean water cleans the filling line 200, and the water flows into the stope through the filling line 200, so that the first filling retaining wall 100 blocks the water. After the filling pipeline 200 is cleaned, the three-way valve 300 is rotated, the three-way valve 300 simultaneously communicates the filling pipeline 200 with the outside, and then the water blocked by the first filling retaining wall 100 flows back through the filling pipeline 200 and flows into the foundation pit 111 through the filling pipeline 200 and the three-way valve 300, so that the water cleaned through the filling pipeline 200 is settled in the foundation pit 111. When the filling pipeline 200 is cleaned next time, the water pump 410 is started, the water inlet pipe 411 pumps settled water in the foundation pit 111, and then the settled water returns to the filling pipeline 200 again through the water inlet pipe 411, the water pump 410 and the water outlet pipe 412 to clean the filling pipeline 200, so that the cyclic utilization of cleaning water is realized.

The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
