A deep reservoir embankment crack maintenance device and method

Abstract

The invention discloses a deep reservoir dam crack overhauling device and method. The deep reservoir dam crack overhauling device comprises a shell, a crack scanning mechanism and a crack repairing mechanism, the crack scanning mechanism is located on the two sides of the top surface of the shell, the crack repairing mechanism comprises a box body, a grouting pipe, a seam breaking mechanism and two supporting columns which are arranged in parallel, a support is arranged on the top surface of the box body, a guide wheel is arranged on the support, the grouting pipe is connected with external equipment through a pulp conveying hose around the guide wheel, connecting rods are arranged at the bottoms of reinforcing rods, a second limiting rod is fixedly connected between the two connecting rods, and the seam breaking mechanism is connected to the second limiting rod and the box body; and the method comprises the steps of the reservoir dam scanning modeling, the crack repairing mechanism installation, the dam cracks, the grouting and the crack overhauling device are recycled. The maintenance method provided by the deep reservoir dam crack overhauling device and method is simple in stepand high in practicability, not only can realize high-precision detection of the dam crack, rapid grouting and sealing can be realized, the labor intensity of manual operation is reduced, and the safety of the reservoir is improved.

Description

technical field [0001] The invention relates to a deep reservoir embankment crack inspection device and method. Background technique [0002] In my country, there are a huge number of reservoir dams, most of which are earth-rock dams. In view of the adverse effects of many external factors, the dams have different degrees of cracks and leakage problems. Once cracks appear, it is very easy to cause leakage problems. , affect the normal use of the reservoir, and will also pose a threat to the production and life downstream of the reservoir. [0003] After the reservoir dam cracks, the impact of the external environment on the concrete, such as weathering, corrosion, dissolution, etc., enters the interior of the dam through the cracks, and continues to destroy it until the dam collapses completely, causing great harm. In some areas, under the action of temperature, The water in the cracks of the embankment repeats the process of freezing, expanding, melting and shrinking, which...

[0003] After the reservoir dam cracks, the impact of the external environment on the concrete, such as weathering, corrosion, and dissolution, enters the interior of the dam through the cracks, and continues to destroy it until the dam collapses completely, causing great harm. In some areas, under the action of temperature, The water in the cracks of the embankment repeats the process of freezing, expanding, melting and shrinking, which will cause cavities at the bottom of the embankment and cause the danger of embankment collapse
