Cast-in-situ aqueduct maintenance device and construction method

Abstract

The invention discloses a maintenance construction method for a cast-in-situ aqueduct. The main construction steps include: (1) construction preparation; (2) installation of slide rails; (3) hoisting of a spray maintenance device; (4) spray maintenance on the inner wall of the aqueduct; (5) Covering with curing film; (6) Partition water; (7) Welding steel wire mesh. In the present invention, a spray maintenance device is arranged to slide and evenly spray water on the inner wall of the aqueduct, so that the inner wall of the aqueduct is sprayed and maintained evenly, and the curing film is pressed and covered by a shaped press frame, which reduces the influence of the aqueduct film from being blown by the wind. The water end plate partitions the aqueduct to facilitate the maintenance of the aqueduct leakage in the later stage.

Description

technical field [0001] The invention relates to the field of aqueduct maintenance, and more particularly relates to a cast-in-situ aqueduct maintenance device and a construction method. Background technique [0002] Aqueducts are commonly used structures for water conveyance projects across valleys, depressions, and river ditches. Generally, the height of the pier body is 20-33m, and the single-span length of the aqueduct body is 20-30m. When the size of the aqueduct is large, the following problems often exist in the maintenance process of the tank wall: (1) the size of the inner wall of the tank is large, and the artificial water spraying maintenance is uneven; (2) the overall length of the tank is long. , It is difficult to check and repair the leaking location; (3) When the curing film is covered, it is often affected by the wind force, and scattered bricks, steel pipes, etc. are used to press the film manually, and the construction efficiency is low. [0003] To sum up...
