Dismantling tool and method of corrugated tube of foundation bolt preformed hole of equipment foundation

Abstract

The invention relates to dismantling tool and method of a corrugated tube of a foundation bolt preformed hole of an equipment foundation. One end of a galvanized steel pipe of a dismantling tool is connected with a cone through threads and the other end is fixed on a rotating dish at the upper part of the dismantling tool, and the upper part and the lower part of the dismantling tool are providedwith opposed penetrating eyeholes for positioning pins to penetrate through. The dismantling method comprises the following steps: fixing the rotating disk at a proper-height position at the upper part of the galvanized steel pipe through the positioning pin at the upper part, regulating the positioning pin at the lower part to be at a proper-height position above hole depth; placing the dismantling tool into the foundation bolt preformed hole, dismantling steel bars on one section of corrugated tube in advance at the mouth of the corrugated tube by using a wire cutter, winding the steel barson the exposed end of the positioning pin at the lower part; rotating the rotating disk, sequentially winding the corrugated tube on the galvanized steel pipe until the corrugated tube is completely wound; unfastening the steel bars of the corrugated tube on the positioning pin at the lower part, pressing by force, and dismantling the steel bars of the corrugated tube on the galvanized steel pipe.The invention manually rotates the corrugated tube to peel off layer by layer from top to bottom through the dismantling tool, is simple and practical, saves large manpower and material resources, has high dismantling efficiency of the corrugated tube, and ensures the grouting construction quality of the preformed hole.

Description

technical field [0001] The invention relates to a novel and practical method for removing bellows of anchor bolts. Background technique [0002] With the development of metallurgical engineering technology, the application of reserved anchor bolt holes in equipment foundations is becoming more and more common. In order to ensure the bolt grouting strength requirements, it is often necessary to temporarily support the shell (such as bellows or plastic pipes) in the reserved holes in time. Demolition, in the process of dismantling, the traditional method is to use wire cutters to peel and dismantle from the nozzle layer by layer, which often has practical problems such as difficulty in force or limited space, resulting in unsatisfactory demolition effect and time-consuming. [0003] The present invention solves the problem of corrugated pipe removal by analyzing the deficiencies of the traditional demolition method and cleverly uses the working principle of the electric drill,...
