Supporting and pressing type caulking machine for concrete face rockfill dam panels

Abstract

The invention provides a supporting and pressing type caulking machine for panel joint caulking construction of concrete face rockfill dams, and the supporting and pressing type caulking machine is used for concrete face rockfill dams. The supporting and pressing type caulking machine is characterized by being provided with a machine body, the machine body is provided with a supporting and pressing device, the supporting and pressing device is provided with a supporting part used for supporting the middle of a cover plate, and a pressing part used for pressing the two sides of the cover plate. The two sides of the pressing part are provided with idler wheels. The heights of the idler wheels on the two sides of the pressing part can be respectively adjusted. The number of the idler wheels on each side of the pressing part is not smaller than two. The relative height between at least two of the idler wheels on the same side of the pressing part can be adjusted. The supporting part can be adjusted and / or replaced according to the sectional form of caulking material to be caulked. The distance between the idler wheels on the two sides of the pressing part can be adjusted. The machine body is provided with a hoop part for hooping the upper surface of the cover plate. The hoop part of the machine body is provided with two or more idler wheels, and the relative height between at least two of the idler wheels of the hoop part of the machine body can be adjusted. The problem that with a current conventional manual caulking method, the compacting efficiency is low, and the quality is poor can be solved with the supporting and pressing type caulking machine.

Description

technical field [0001] The invention relates to a construction machine, in particular to a support press-type caulking machine used for filling construction of concrete face rockfill dam face joints and caulking materials. Background technique [0002] Concrete face rockfill dam is a dam form widely used in the construction of hydropower stations at home and abroad, and has become the main comparison or preferred dam type in my country. In the next 10 years, with technological progress, my country will promote the construction of more face rockfill dams. [0003] The concrete face rockfill dam uses the rockfill body as the main force-bearing structure to bear the reservoir water pressure, and the reinforced concrete face plate poured from bottom to top on the facing surface of the rockfill body is the anti-seepage structure. Due to factors such as the settlement and deformation of the dam body, the concrete panels need to be poured in blocks, so that dozens of joints are fo...

AI Technical Summary

Problems solved by technology

Since the caulking materials sold in the domestic and foreign markets are inherently viscous and elastic-plastic, and are constructed on the steep slope of the dam, manual compaction is not strong enough and compaction is extremely difficult

Therefore, the manual compaction of the caulking material is inefficient and the compaction quality is not very satisfactory

[0007] To sum up, in order to solve the problems of low compaction efficiency and poor quality of conventional manual caulking methods, the present invention proposes a brace-type caulking machine for filling construction of concrete face rockfill dam face joint caulking materials
