Main bridge deck shot blasting and composite modified asphalt waterproof bonding layer construction process

Abstract

The invention discloses a main bridge deck shot blasting and composite modified asphalt waterproof bonding layer construction technology. The main bridge deck shot blasting and composite modified asphalt waterproof bonding layer construction technology comprises the following steps that firstly, a bridge deck is preliminarily cleaned; 2, a shot blasting machine is debugged in place; 3, shot blasting operation is conducted; step 4, cleaning steel shots; 5, floating ash cleaning; and 6, a waterproof bonding layer is constructed, preliminary cleaning of the bridge deck in the first step is completed through bridge deck pavement layer shot blasting equipment, and the bridge deck pavement layer shot blasting equipment adopts equipment with synchronous laitance removal and dust collection functions and self-circulation recovery shot blasting equipment with a driving walking system to conduct bridge deck concrete pavement layer treatment. According to the main bridge deck shot blasting and composite modified asphalt waterproof bonding layer construction technology, the construction quality is good, hot asphalt is sprayed uniformly enough, and the integrity of main bridge deck construction can be guaranteed.

Description

Technical field [0001] The present invention relates to the technical field of main bridge bridge surface construction, and is specifically a main bridge bridge surface shot blasting and composite modified asphalt waterproof bonding layer construction process. Background technique [0002] When the main bridge is constructed, it is necessary to take the main bridge bridge surface construction to handle the blasting layer treatment to ensure the quality of the main bridge bridge, but the existing main bridge bridge deck shot and Composite modified asphalt waterproof bonding layer construction process still has certain defects, such as: [0003] Existing main bridge bridge-strippets and composite modified asphalt waterproof bonding layer construction process is often not guaranteed, and the hot asphalt sprinkle is not uniform, so we propose a main bridge scholastic blasting and Composite modified asphalt waterproof bonding layer construction process in order to solve the problems p...
