Device and method suitable for cover culvert wall body template moving construction

Abstract

The invention discloses a device and method suitable for cover culvert wall body template moving construction. The device comprises stainless steel rods, a prefabricated steel plate, channel steel, prefabricated bearings, fixing rods with U-shaped notches, and the like. Firstly, the stainless steel rods and the prefabricated steel plate are welded to form a stable rail, the prefabricated steel plate and the channel steel are welded to form a whole to serve as a template moving upper rail, and then, the channel steel and wall body bottom later templates are firmly welded; meanwhile, a stable rail formed by welding of the other set of stainless steel rods and the prefabricated steel plate is put into the channel steel to serve as a lower rail, and the lower rail and the upper rail keep in the same vertical plane; the fixing rods with the U-shaped notches are embedded into inner rings of the prefabricated bearings to form an embedded and locked whole and then put into the upper and lowerrails, and the notches of the fixing rods align at groove legs on the outer side of the channel steel; the four corresponding prefabricated bearings are stored in the templates of each side, and the sixteen prefabricated bearings are divided into four sets, wherein the fixing rods with the U-shaped notches are embedded and locked into the prefabricated bearings. The device can conduct template moving on the wall body templates in efficient, quick and damage-free modes on the basis of the cover culvert wall body structure construction characteristics.

Description

technical field [0001] The invention belongs to the technical field of road engineering, and relates to a device and method suitable for formwork transfer construction of a cover plate culvert wall body. Background technique [0002] Culverts are drainage holes (water passages) built under the roadbed and built below the road surface in order to make the road pass through the canal smoothly in the construction of highway engineering. Through this structure, water can flow through the road for use It is an important part of highway engineering to discharge floodwater across natural valleys and depressions, or across large and small roads as overpasses for people, livestock and vehicles, or to irrigate farmland as water channels. Cover culvert construction is divided into base treatment, foundation construction, wall construction, and cover construction. Considering that the foundation will have uneven settlement in the later stage of construction, according to the constructi...

Problems solved by technology

[0005] (1) Low efficiency and low safety factor

In the case of a certain number of workers, in order to ensure the safety of personnel during the process of moving the formwork, it is necessary to move the four formworks on both sides of the wall simultaneously or alternately forward. There are extremely high demands on physical strength, and the speed is slow, so it cannot be operated continuously; if the single formwork moves too fast, it will seriously affect the stability of the one-sided formwork and reduce the safety factor in the construction process

[0006] (2) Destructive

The pry bar needs to use the foundation to form a lever in the process of moving the mold, so there is a certain strength requirement for the culvert foundation. The pry bar will inevitably exert a force on the surface of the foundation during the mold moving process, which will not only damage the smoothness of the foundation surface, affect the appearance, and even It will affect the integrity of the side of the foundation, causing the foundation to appear missing corners

[0007] (3) It is not conducive to precision control

[0008] The track construction method adopted in the existing culvert construction requires the use of large steel pipe support trolleys and a large number of auxiliary equipment and machines. Widely promoted
