Movable sealed intelligent maintenance and construction method for cast-in-place beams constructed by cantilever method

Abstract

The invention belongs to the technical field of maintenance and construction of cast-in-place beams constructed by a cantilever method. In order to solve the problems that bottom plates and web platesof continuous beams or continuous rigid beams are not maintained in place, the invention provides a movable sealed intelligent maintenance and construction method for cast-in-place beams constructedby a cantilever method. A maintenance process is completed through a sealed movable maintenance device; an outer slide beam of a cast-in-place beam hanging basket serves as a forward moving slide railof the sealed movable maintenance device; the sealed movable maintenance device comprises a bearing mechanism, a water supply pipeline system as well as left and right sealing plates, a bottom sealing plate and an end plug which are arranged around the outer side of a cast-in-place beam section; and the left and right sealing plates, the bottom sealing plate and the end plug are sealed by rubber.By virtue of the hanging basket structure, the outer slide beam of the hanging basket structure is extended by two sections, a slide base and a temporary fastening device are additionally arranged toserve as main stress components of the sealed maintenance device, intelligent maintenance is performed while realizing forward movement following the construction progress, and individual operation is not needed.

Description

technical field [0001] The invention belongs to the technical field of maintenance construction of cast-in-place beams by cantilever method, and in particular relates to a mobile sealing intelligent maintenance construction method for cast-in-situ beams constructed by cantilever method. Background technique [0002] As large-span cantilever cast-in-place beams are widely used in high-speed railways, highways, municipal projects, etc., the current technology lacks the maintenance technology and tooling equipment for the bottom web of cast-in-place beams, and there is basically no maintenance for the bottom web of continuous beams on site. Covering and sprinkling maintenance on the top surface of the beam body makes the maintenance of the concrete structure of the cast-in-place beam bottom web always a major problem in engineering construction. The cast-in-place beam concrete structure cannot be properly maintained in time, resulting in surface cracks of varying degrees Severe...

AI Technical Summary

Problems solved by technology

[0003] The present invention aims to solve the problems that continuous beams or continuous rigid beam bottom plates and webs cannot be maintained in time after pouring, or cannot be maintained due to construction space conditions, maintenance is not in place, maintenance methods are not intelligent, and maintenance parts are uneven. The purpose of intelligent maintenance of the bottom web of cast-in-place beams by cantilever method is to improve the construction quality of cast-in-place beam concrete structures, promote the improvement of cantilever cast-in-place beam construction technology and construction methods, develop intelligent maintenance tooling and equipment, and improve construction efficiency, etc.
