Abstract
A system based on tunnel adverse slope drainage relates to a system based on tunnel adverse slope drainage. The tunnel drainage system is mainly designed for solving the problems of inaccurate moving position and low speed of the existing tunnel drainage system. The concrete prefabricated part lifting trolley comprises a trolley, a submersible pump is installed on the trolley, two hydraulic telescopic rods are arranged at the front end of the trolley, the front ends of the two hydraulic telescopic rods are connected with a counterweight frame, and a concrete prefabricated part is placed in the counterweight frame. The counterweight frame is provided with a travelling wheel, and the two hydraulic telescopic rods are connected with each other through a first hydraulic oil pipe and a second hydraulic oil pipe; vertical steel pipes are arranged on the side surfaces of the counterweight frame and the trolley. The rear end of the submersible pump is connected with a drain pipe through a steel corrugated expansion joint. The first hydraulic oil pipe is connected with a third hydraulic oil pipe, the second hydraulic oil pipe is connected with a fourth hydraulic oil pipe, the third hydraulic oil pipe and the fourth hydraulic oil pipe are connected with a manual reversing valve, and the manual reversing valve is provided with an oil pipe connected with a hydraulic pump and a hydraulic oil tank. The advantage is that can be fast, accurate completion pump drainage system's antedisplacement.
Description
The technical field is as follows:
the invention relates to a tunnel-based adverse slope drainage system.
Background art:
along with the continuous improvement of the infrastructure construction technology in China, the underground engineering construction is rapidly developed, a plurality of long-distance high-burial depth water-rich reverse slope drainage tunnels appear, sudden and large water gushes sometimes happen during construction in unfavorable geological sections, and the existing pumping and drainage system is damaged to cause the flooding. After the tunnel is flooded, the pumping and drainage construction needs to move the pumping and drainage system forward continuously along with the reduction of the water level so as to pump and drain accumulated water in the tunnel quickly.
However, when the pumping drainage system is moved underwater in a small-section tunnel, the situations of inaccurate moving position, low speed, long time consumption, easy damage and the like exist, so that the investment of personnel and mechanical equipment is increased, the pumping drainage efficiency is low, the construction cost is increased, and the construction progress is influenced.
The invention content is as follows:
the invention aims to solve the technical problem of providing a tunnel reverse slope drainage-based system which is accurate in moving position, high in speed, easy to operate and low in personnel and mechanical equipment investment.
The above object is achieved by: it includes the dolly, and the walking wheel passes through the axle to be installed on the dolly, and a plurality of immersible pump is installed on the dolly, and the dolly front end is fixed with first hydraulic telescoping rod and second hydraulic telescoping rod, and two hydraulic telescoping rod's front end all is connected with the counter weight frame, places C25 concrete precast block in the counter weight frame and carries out the counter weight.
The counterweight frame is also provided with traveling wheels, a rod cavity of the first hydraulic telescopic rod is connected with a rodless cavity of the second hydraulic telescopic rod through a first hydraulic oil pipe, and the rodless cavity of the first hydraulic telescopic rod is connected with a rod cavity of the second hydraulic telescopic rod through a second hydraulic oil pipe;
vertical steel pipes are arranged on the side face of the counterweight frame and the side face of the trolley and serve as guide marks. And (4) coating reflective paint on the guide mark.
The rear end of each submersible pump is provided with a steel corrugated expansion joint, and the rear end of each steel corrugated expansion joint is connected with a drain pipe.
The first hydraulic oil pipe is connected with a third hydraulic oil pipe, the second hydraulic oil pipe is connected with a fourth hydraulic oil pipe, the other ends of the third hydraulic oil pipe and the fourth hydraulic oil pipe are connected with a manual reversing valve, the manual reversing valve is provided with an oil pipe which is connected with a hydraulic pump and a hydraulic oil tank, the hydraulic pump is connected with the hydraulic oil tank, and the hydraulic oil tank is welded on the trolley; when the first hydraulic oil pipe is supplied with oil, the first hydraulic telescopic rod can be extended out, the second hydraulic telescopic rod retracts, and steering is completed under the combined action.
The device mainly moves forwards through self weight, adopts a loader with model number ZL50CN to provide power when moving backwards, and realizes movement through the traction of a steel wire rope.
The invention has the advantages that: the steel corrugated expansion energy-saving device can provide certain elastic deformation, avoid the water leakage phenomenon caused by the damage of part of elements due to brittle deformation during steering, and reduce the pumping and drainage efficiency. When the device is used for moving pumping drainage, the forward movement of a pumping drainage system can be quickly and accurately completed, and the pumping drainage efficiency can be greatly improved. In addition, the device has the advantages of accurate movement, simple structure, low cost, simple manufacture and operation and the like.
