Continuous beam cantilever casting secondary real-time counterweight system and construction method

Abstract

The invention belongs to the technical field of bridge construction and particularly relates to a continuous beam cantilever casting secondary real-time counterweight system and a construction method. The device solves a problem that the manual uncertainty risk is large due to the fact that the unbalance deviation is kept within an allowable range through a method of manually commanding and controlling the concrete pouring variance in traditional continuous beam concrete pouring, and comprises a central water tank arranged in the center of a 0 # section, poured sections are arranged on the two sides of the 0 # section, and hanging baskets are installed on the poured sections; a hanging basket refitting part capable of moving forwards along with the hanging basket is installed on the hanging basket, to-be-poured section water tanks are installed on the left side and the right side of the hanging basket refitting part correspondingly, and the central water tank supplies water to the to-be-poured section water tanks; an adjustable laser emitting device II and an adjustable laser emitting device I are installed at the end, close to the to-be-poured section, of the poured section, a double-sided photosensitive induction device is arranged in the center of the 0 # section, and pressure sensors are arranged between the bottoms of the hanging basket longitudinal beams on the two sides and the poured beam section.

Description

technical field [0001] The invention belongs to the technical field of bridge construction, in particular to a continuous beam cantilever pouring secondary real-time counterweight system and a construction method. Background technique [0002] When pouring continuous beam concrete, considering the overall cost, a pump pipe is usually used to pour concrete at both ends of the continuous beam T structure. In the process of simultaneous pouring, the concrete at both ends is usually poured alternately, that is, a certain amount of concrete is poured at one end of the continuous beam (defined as I end or left end), and then the concrete pump pipe is transferred to the other end (defined as I end or left end). A certain amount of concrete is poured for the II end or the right end), and then the concrete pump pipe is transferred to the I end for pouring, and the concrete is poured alternately in this cycle to keep the balance between the left and right ends of the continuous beam (...

AI Technical Summary

Problems solved by technology

[0011] In order to solve the problem that the traditional pouring of continuous beam concrete relies on manual command and control of the concrete pouring variance method to keep the unbalanced deviation within the allowable range, the artificial uncertainty risk is large, and the invention provides a continuous beam cantilever pouring two-stage Real-time counterweight system and construction method
