Bridge demolishing construction method and device thereof

Abstract

The invention relates to a bridge demolishing construction method and a device thereof. The bridge demolishing device comprises a main support and hoisting systems, wherein the hoisting systems are arranged on all frame bodies, and each hoisting system comprises a pulley block, a hoist, a leading pulley, a lifting appliance and lifting rods. The hoists are arranged at the tail part of the main support and fixedly mounted to a tail crossbeam, the leading pulleys are mounted above a top crossbeam, the pulley blocks are mounted under the top crossbeam and connected with the lifting appliances, the lifting rods are connected with the lifting appliances, casters are mounted on lower steel beams, the casters which correspond to rails move along the rails, and the casters are driven to roll by motors through driving wheel boxes. The bridge demolishing device adopts the hoists as hoisting power, a to-be-cut bridge is fixed through four points, and then the cutting is performed. The cut bridge parts are integral modules, so that the transportation is convenient, the demolishing efficiency is high, and the demolishing construction is safe and reliable. Construction waste formed after demolishing is also integral modules, so that the transportation is convenient.

Description

technical field [0001] The invention relates to a bridge demolition construction method and equipment thereof, belonging to special equipment for bridge demolition construction. Background technique [0002] Due to the needs of economic development, the relevant infrastructure construction is constantly improving. Road and bridge construction is the foundation of infrastructure construction. Bridges that are outdated in infrastructure construction and are no longer suitable for economic construction need to be demolished. The usual bridge demolition includes blasting demolition or bridges located on land. Or in the water, use direct demolition or set up brackets for demolition, but no matter what kind of demolition is used, it will be a problem to collect and transport away the garbage after demolition. The domestic invention patent with the patent number of 2008100478037 discloses a method for bridge construction , the equipment used in this method is moved by chain hoists,...

[0002] Due to the needs of economic development, the relevant infrastructure construction is constantly improving. Road and bridge construction is the foundation of infrastructure construction. Old bridges in infrastructure construction that are no longer suitable for economic construction need to be demolished. The usual bridge demolition includes blasting demolition or bridges located on land. Or in the water, use direct demolition or set up brackets for demolition, but no matter what kind of demolition is used, it will be a problem to collect and transport away the garbage after demolition. The domestic invention patent with the patent No. 2008100478037 discloses a method for bridge construction , the equipment used in this method is moved by chain hoists, so the efficiency is low, and it is used for construction, not suitable for demolition construction
