Self-propelled movable formwork for construction of double-rectangle water conservancy aqueduct

Abstract

Provided is a self-propelled movable formwork for construction of a double-rectangle water conservancy aqueduct. The self-propelled movable formwork for construction of the double-rectangle water conservancy aqueduct comprises an outer beam system (1), an outer mould system (2), inner beam systems (3), inner mould systems (4), an electronic control system (5), a hydraulic system (6) and the like. The outer beam system (1) is a main load bearing system of the self-propelled movable formwork, and mainly comprises an outer beam (1a), a first outer beam leg (1b), a second outer beam leg (1c), a third outer beam leg (1d), a fourth outer beam leg (1e) and a rear outer beam walking portion (1f), wherein a box-shaped composite beam mode is adopted by the outer beam (1a), the outer beam (1a) is of a double-beam form, the center distance between the double beams is 9.5m, and the double beams are combined into a whole through two end-connecting beams, eight middle-connecting beams and sixteen outriggers which are symmetrical in a left-and-right mode. An outer girder serves as a main bearing structure of an aqueduct construction machine, the load of the pouring state is transmitted to the top of a poured pier through the third outer beam leg and the fourth outer beam leg, and the poured pier straddles the front portion and the rear portion.

Description

technical field [0001] The invention relates to a self-propelled mobile formwork used for the in-situ cast-in-place construction of a rectangular water conservancy aqueduct, in particular to the construction of a rectangular double-groove aqueduct. Background technique [0002] With the deepening of the construction of the middle line of my country's South-to-North Water Diversion, more and more artificial above-ground river sections have appeared. Usually, above-ground rivers use aqueducts as water channels. These large-tonnage hydraulic aqueducts are all made of reinforced concrete. Aqueduct loads. [0003] Although the existing commonly used full house bracket method is mature and widely used, its shortcomings are unavoidable: [0004] 1. The initial cost investment is relatively large. If the construction progress similar to that of the present invention is achieved, at least two half-span and half-full hall supports and two sets of formwork need to be invested; [0005...

Problems solved by technology

[0003]Although the existing and commonly used full house bracket method is mature and widely used, its shortcomings are unavoidable:

[0004]1. The initial cost investment is relatively large. If the progress similar to the construction of the present invention is achieved, at least two half-span and half-full hall supports and two sets of formwork need to be invested;

[0005]2. The construction period is long, and each hole requires preloading inspection, which
