Description

Protection device for movable sewage pump of tunnel inclined shaft face

Technical Field

The utility model relates to a sewage pump protection device, in particular to a mobile sewage pump protection device for a tunnel inclined shaft face.

Background

In tunnel construction, in order to facilitate the construction, auxiliary tunnels are often arranged, and some auxiliary tunnels are large-gradient inclined shafts, so that ultra-long distance large-gradient reverse slope drainage is often required in the construction process. When the reverse slope drainage height difference is large (for example, the reverse slope drainage height difference is hundreds of meters), and the water inflow in the tunnel is large, the difficulty of the large-gradient and ultra-long-distance reverse slope drainage is extremely large, and the whole process of reverse slope drainage operation is needed during the construction period of the inclined shaft.

In the construction process, the tunnel face is required to be pumped and drained in the whole process. Because the face is carrying out blasting construction, slag tap construction, guniting and supporting the construction, often be accompanied with a large amount of blasting rubble, slag tap rubble and guniting rebound material, rubble, guniting rebound material can damage, jam the water pump of drainage, consequently every time blasting, slag tap, guniting all need to pause the water pump and draw water in the time of constructing to need artifical cooperation mechanical equipment to remove drainage equipment many times, waste time and energy influences the construction progress, influences face drainage efficiency moreover, brings the hidden danger for the construction safety.

Disclosure of Invention

Aiming at the defects in the prior art, the utility model provides the mobile sewage pump protection device for the tunnel inclined shaft face of the sewage pump, which has a simple structure and can effectively protect the sewage pump.

The utility model is realized by the following technical scheme: a tunnel inclined shaft face mobile sewage pump protection device is characterized in that: including the steel box of rectangle, the bottom and the preceding tip of steel box are open structure, and the roof upper portion of steel box is fixed to be provided with rings, all is provided with a plurality of hole of permeating water on the three lateral wall of steel box, and the diameter of hole of permeating water is 10mm, and the centre-to-centre spacing of adjacent hole of permeating water is 30mm.

When the utility model is used, the utility model is placed in a water collecting pit at the water collecting position of the tunnel face, the top surface of the steel box body is upward, the front end part of the steel box body faces away from the tunnel face, the sewage pump for pumping and draining water is placed in the steel box body, and the drain pipe extends out from the front end of the steel box body. The water in the water collecting pit flows into the steel box through the water permeable holes on the side wall of the steel box, broken stone and guniting material are blocked outside the steel box, and the sewage pump can pump water normally. Because the top of steel box is not opened the hole of permeating water, and the sewage pump is established in the steel box by the complete cover, consequently can effectively keep apart debris such as rubble, guniting material get into the box, prevent that the sewage pump from blockking up, effectively avoided blasting rubble, slag tap rubble to damage the sewage pump simultaneously, slag tap, the construction period of guniting does not influence sewage pump drainage operation, does not influence the drainage effect of face. Through setting up rings, the removal of the device of being convenient for.

Further, in order to ensure the drainage effect, each side wall is provided with four rows of holes that permeate water at uniform intervals, the interval between every two adjacent rows of holes that permeate water is 80mm, wherein four rows of holes that permeate water on the side wall of steel box rear end all with steel box bottom surface parallel arrangement, four rows of holes that permeate water on two side walls of steel box length direction all are certain contained angle with steel box bottom surface and arrange, and the low end of every row of holes that permeate water is located the front end side of steel box. Four rows of water permeable holes on two side walls of the length direction of the steel box body adopt a mode of being arranged at a certain included angle with the bottom surface of the steel box body, so that the structural strength of the steel box body can be ensured, the steel box body can adapt to the gradient of an inclined shaft, the water permeable effect is ensured, and the water drainage efficiency is ensured.

Further, in order to ensure the structural strength of the steel box body, the steel box body is made of a steel plate with the thickness of 10 mm.

The beneficial effects of the utility model are as follows: the utility model has simple structure, can ensure the water pumping and draining effect, can protect the sewage pump from being influenced by broken stone and guniting material, can protect the sewage pump from being damaged by blasting and slag and broken stone, can prevent the sewage pump from being blocked by guniting material, reduces the loss of the water pump, reduces the maintenance cost of equipment and lightens the labor intensity of personnel.
