Problems solved by technology

[0002] The engineering volume of the cast-in-place wall of the culvert is relatively large, and the construction of the wall is carried out by using the combination of conventional steel pipe supports and plane formwork. There are irregularities around the tie rod holes, dew sand and water leakage in the tie rod holes. It takes a lot of manual work to polish the wrong platform, block the tie rod holes, waterproof the tie rod holes and apply waterproof asphalt coating on the back of the wall.

Abstract

The invention discloses an electric slip-form pull-rod-free integral through-culvert wall body pouring formwork trolley, which comprises a trolley and formworks symmetrically distributed on two sidesof the trolley, wherein each formwork comprises an outer formwork, an inner formwork and an end formwork; a first pull rod is arranged between the outer formwork and the inner formwork; and the trolley comprises a walking device, a reinforcing device, a supporting device and a lifting device. The formwork system of the electric pull-rod-free formwork trolley is assembled and formed at one time andis recycled, the turnover is convenient and fast, the formwork trolley is less in manual investment during operation, the construction efficiency is high, the appearance quality is good, the safety factor is high, the installation amount of steel pipe brackets is greatly reduced, the safety standardization is higher, and the construction progress can reach one cycle per day; and the formwork trolley effectively avoids the problem of water seepage of wall body pull rod holes caused by the construction of culverts by using prior equipment, solves the quality defects of obvious formwork splicingjoints, staggered construction, color difference of concrete and the like, and ensures the flatness of large wall bodies of the culverts and engineering solid quality.

Description

technical field [0001] The invention relates to a formwork trolley for pouring culvert walls, in particular to an electric sliding form trolley for integral culvert wall pouring formwork without tie rods. Background technique [0002] The engineering volume of the cast-in-place wall of the culvert is relatively large, and the construction of the wall is carried out by using the combination of conventional steel pipe supports and plane formwork. There are irregularities around the tie rod holes, dew sand, and water leakage in the tie rod holes. It takes a lot of manual work to polish the wrong platform, block the tie rod holes, waterproof the tie rod holes, and apply waterproof asphalt coating on the back of the wall. Contents of the invention [0003] The object of the present invention is to provide an electric sliding form trolley for integral culvert wall pouring formwork without tie rods. The trolley is hoisted and fixed on the outer mold and the inner mold through the...
