Construction method of high-performance underwater blast-resistant concrete protective layer based on pouring technology

Abstract

The invention provides a high-performance underwater anti-explosion concrete protective layer construction method based on a pouring technology. The method comprises the following steps: step 1, enclosing a to-be-protected surface of a wading building by adopting a water blocking member, so as to isolate an external water body, and reserving a certain distance between the water blocking member andthe to-be-protected surface; step 2, pumping water isolated between the water blocking member and the to-be-protected surface of the wading building by adopting water pumping equipment; and step 3, filling underwater quick-setting concrete containing high-performance hollow glass beads between the water blocking member and the to-be-protected surface by adopting the pouring technology, wherein each cubic meter of the underwater quick-setting concrete contains 58.5 kg-195 kg of high-performance hollow glass beads, and the high-performance hollow glass beads are hollow glass beads subjected tomodified treatment by silane coupling agent G-570. By adopting the method, the anti-explosion performance of the wading building can be effectively improved.

Description

technical field [0001] The invention belongs to the technical field of underwater anti-explosion protection, and in particular relates to a construction method of a high-performance underwater anti-explosion concrete protective layer based on pouring technology. Background technique [0002] In modern engineering, concrete is widely used as an excellent traditional building material, and the construction technology of concrete is also changing with each passing day. At present, the construction methods for wading structures such as bridge piers are mostly used to drain the surrounding river water, and spray anchor technology to the building. However, this method has the disadvantages of heavy workload, long construction period, and high cost, so it is urgent to improve the existing technology. [0003] At present, the traditional concrete used for repairing wading buildings has the characteristics of long solidification time and poor self-flowing properties, and is easily ta...
