Description

TECHNICAL FIELD

[0001] The present application relates to dam seepage prevention treatment technical field, specifically to a kind of for pumped storage power station lower reservoir dam seepage prevention treatment spraying device. BACKGROUND

[0002] It is known that spraying treatment in dam seepage prevention treatment is a method of forming seepage prevention coating on dam surface using spraying technology, mainly suitable for seepage prevention treatment of dam surface of concrete dam, mortar stone dam, etc. It can also be used for seepage prevention of slope surface of earth-rock dam. For dam with defects such as cracks and honeycomb surface, spraying treatment can effectively seal these defects to prevent water seepage. Commonly used spraying materials include polymer cement-based waterproof coating, polyurethane waterproof coating and epoxy asphalt coating. Polymer cement-based waterproof coating has good adhesion and impermeability, can be closely combined with concrete surface. Polyurethane waterproof coating has high elasticity and crack resistance, can adapt to certain deformation of dam. Epoxy asphalt coating has excellent water resistance and corrosion resistance, suitable for dam seepage prevention in harsh environment.

[0003] The dam of pumped storage power station lower reservoir needs to cooperate with the operation of pumped storage power station, so the water storage and water release will be more frequent. The spraying maintenance for dam seepage prevention needs to be more frequent. The existing technology has the following problems: although the top of the dam can be conveniently sprayed and laid, on the side wall of the dam with large slope, the personnel can work at the bottom of the dam, but the personnel at high position usually need to move the hoisting equipment together with the spraying device and the personnel to the working position for spraying. This not only needs to be improved in efficiency, but also has the risk of falling of personnel, and the labor consumption is large.

[0004] Based on the above-mentioned situation, we find that the existing spraying device for pumped storage power station lower reservoir dam seepage prevention treatment can hardly avoid the above problems at the same time. Therefore, we propose a spraying device for pumped storage power station lower reservoir dam seepage prevention treatment, which can avoid personnel working on the side wall of the dam, improve safety, quickly spray horizontally or parallel to the side wall of the dam to improve efficiency, can be towed by carrier to reduce labor consumption.
