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

Abstract

A self-propelled mobile formwork for the construction of a double rectangular water conservancy aqueduct, including an outer beam system (1), an outer formwork system (2), an inner beam system (3), an outer formwork system (4), and an electric control system (5 ) and the hydraulic system (6); the outer beam system (1) is the main bearing system of this equipment, mainly composed of the outer beam (1a), the No. 1 leg of the outer beam (1b), and the No. 2 leg of the outer beam (1c), outer girder No. 3 leg (1d), outer girder No. 4 leg (1e), and outer girder rear travel (1f); the outer girder (1a) is in the form of a box-shaped composite girder, which is in the form of double girders. The beam center distance is 9.5 meters, and the two beams are formed as a whole by two sets of end connecting beams, 8 sets of intermediate connecting beams, and 16 sets of left and right symmetrical cantilever beams; the outer main beam is the main load-bearing structure of the slot machine, and the pouring state is passed The No. 3 and No. 4 outriggers transmit the load to the top of the pier before and after the pouring span respectively.

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...

AI Technical Summary

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 wastes a lot of time;

[0006]3. The full house support method has high requirements on the bearing capacity of the foundation, and is not suitable for high groove piers. It is difficult to construct when crossing ditches, rivers and other landforms;

[0007]4. The treatment of the weak foundation and the re-cultivation after construction also need to consume a lot of labor and materials;

[0008]5. The construction loss of the full hall support is relatively large
