Embodiment Construction

[0039] The present invention will be further described below in conjunction with accompanying drawing, and the structure and principle of this device are very clear to those skilled in the art. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0040] This method uses a multi-pole lining trolley to control the overall rigidity of the frame, drives the trolley to travel with a motor-driven traveling mechanism, and uses hydraulic cylinders and screw jacks to adjust the formwork in place and form the tunnel concrete forming when the mold is closed. Multi-pole lining The trolley adopts the construction method of pouring the side wall and the arch part together or pouring the arch wall separately according to the size of the tunnel section, the construction period and the supply of concrete. The bottom of the multi-pole type trolley is driven by a motor, and the trolley is easy to...

Abstract

The invention relates to the technical field of construction, in particular to a reinforced concrete modelling construction method which is applicable to a large section chamber. According to the super-large section chamber reinforced concrete modelling construction method, a multi-vertical-rod type lining trolley is adopted to control the integral rigidity of a rack, a motor drives a walking mechanism to drive the trolley to move, formwork in place and tunnel reinforced concrete forming of closing mold are adjusted through a hydraulic oil cylinder and a screw jack, the multi-rod type lining trolley adopts a method of pouring the side wall and the arc portion together or separately pouring the arc wall according to the size, the construction period and the concrete supply conditions of the tunnel section. According to the reinforced concrete modelling construction method, the multi-rod type lining trolley is adopted, the side wall and the arc portion can be poured separately and simultaneously, the construction period and costs are saved, the splicing time and material reshipment are reduced, the trolley movement and positioning speed is rapid, and personnel operation is facilitated; the multi-rod trolley adopts full-hydraulic vertical closing mold, the motor driving is matched with walking of the rail, accurate positioning is easy, braking is convenient, movement safety risks are small, and the structure is reasonable.

Description

[technical field] [0001] The invention relates to the technical field of construction, in particular to a reinforced concrete mold construction method suitable for large-section chambers and extra-large-section railway and highway tunnels. [Background technique] [0002] The general engineering command hall is a typical large-section chamber with a maximum excavation section of 300 square meters. As the command hall is the core of the project and its structural and functional requirements, the requirements for the smoothness of the lining concrete surface, lining construction joints, and staggered platforms are very high. , due to its large cross-section, large concrete volume, and large lateral pressure during concrete pouring, the overall strength and stiffness of the lining platform are very high, and it is difficult to move and manufacture the lining platform, and it is difficult to ensure the stability of the platform. The flatness of the concrete surface High standard....
