Problems solved by technology

[0002] Because pile foundation is the most commonly used form of foundation in the maintenance pile construction of large bridges, super-large bridges and subway foundation pits, and the number of piles is huge, we usually use small machines or vibrating hammers to clean the pile head concrete manually, which is safe. There are many hidden dangers and high construction costs

Abstract

The invention provides a reinforced concrete pile head shearing and crushing device which comprises pile head scissor crushing arms, scissor arm fixed support large arms, a support working disc, a dynamic and hydraulic jack, a mechanical connecting piece, a dynamic and hydraulic jack fixed column, scissor arm top end fixed bolts and a scissor arm fixed supporting point bolt, wherein one end of the dynamic and hydraulic jack is connected with the dynamic and hydraulic jack fixed column, and the other end of the dynamic and hydraulic jack is connected with the scissor arm top fixed bolts of the pile head scissor crushing arms; the dynamic and hydraulic jack fixed column is fixedly arranged on the support working disc; the mechanical connecting piece is arranged on the center of the support working disc and is connected with the top end of a large arm of an excavating machine; the four pile head scissor crushing arms are respectively arranged on the support working disc and are symmetrically and uniformly arranged; a hydraulic system of the excavating machine is connected with the dynamic and hydraulic jack and is used for supplying power to the dynamic and hydraulic jack. Finished products of materials used in the device can be purchased from the market, and the device is simple in overall structure and free from special structural requirement.

Description

technical field [0001] The invention relates to a reinforced concrete pile head shearing and crushing device, which belongs to the construction field of bridge engineering pile foundations and subway foundation pit maintenance pile foundations. Background technique [0002] Because pile foundation is the most commonly used form of foundation in the maintenance pile construction of large bridges, super-large bridges and subway foundation pits, and the number of piles is huge, we usually use small machines or vibrating hammers to clean the pile head concrete manually, which is safe. There are many hidden dangers and high construction costs. In order to achieve the goal of liberating heavy physical labor and replacing dangerous working parts with machinery, while reducing construction costs and improving construction efficiency, on the basis of summarizing previous construction operations, a reinforced concrete pile head shearing and breaking device was invented, thereby It re...
