Steel-concrete mixed structure underground box-shaped pipe gallery and its manufacturing method

Abstract

The invention discloses an underground box type pipe gallery of a steel-concrete mixed type structure. The underground box type pipe gallery comprises box type pipe sections, wherein each box type pipe section is formed by splicing a top plate, a bottom plate and two side plates. The box type pipe sections are spliced in the axial direction to form the box type pipe gallery. Concrete longitudinal columns are arranged at axial edges of the box type pipe sections. Concrete transverse columns are arranged at the two ends of the top plates or the bottom plates. Concrete stand columns are arranged at the two ends of the side plates. The concrete transverse columns and the concrete stand columns are in end-to-end connection to form a frame type framework. In the underground box type pipe gallery of the steel-concrete mixed type structure, the longitudinal columns and the frame type framework bear the main loading, and the bearing capacity of the pipe gallery is increased; by means of a bridge steel web plate structure, shearing resistance of the pipe gallery is enhanced; the side plates or sheets in the pipe gallery serve as wall boards of the pipe gallery, also serve as web plates of the anti-shearing bridge steel web plate structure of the pipe gallery and are utilized ingeniously; on the basis of a double reinforcing structure, the bearing capacity of the pipe gallery is greatly increased; and under the circumstance that the filling height remains the same, the structural wallboards are thinner, and materials are saved.

Description

technical field [0001] The invention discloses a box-shaped pipe gallery, in particular to an underground box-shaped pipe gallery with a steel-concrete mixed structure and a manufacturing method thereof.

Problems solved by technology

The patent number applied for is 201510960789.X "Steel Urban Underground Box Pipe Gallery", which is made of pure steel material, and its bearing capacity is limited, so it cannot be applied to large-diameter sections and high fill; the applied patent number is 2015106007884 "Prefabricated assembled steel-concrete composite steel pipe and its manufacturing method", patent number 201510598743.8 "prefabricated assembled steel-concrete composite pipe and its manufacturing method", patent number 201510600759.8 "steel-concrete composite structure pipe with spiral reinforcement ring and Its production method" and the patent number is 201610237478.5 "Integrated Pipe Gallery with Frame Type Combination Structure". , there are the following disadvantages ①. The inner bottom of the pipe gallery is curved, not flat, which is not convenient for maintenance personnel and maintenance equipment to pass through. It is necessary to build a special platform at the inner bottom of the pipe gallery

②. The walls on both sides of the pipe gallery are also curved, which is not conducive to the arrangement of pipe racks and pipelines

③. For integral circular cross-section pipes, there are difficulties in transportation, and the pipe diameter is greater than 3.5 meters and exceeds the limit

④. There are also transportation disadvantages for the segmented circular arc section. Because the plates are arc-shaped structures, when stacked and transported, the higher the stack, the more the plates are stressed during the transportation process, which is easy to cause the plates Unpredictable radian deformation, in severe cases, transported to the site cannot be docked and assembled, and rework is required

⑤. Compared with the straight plate, the circular arc plate is difficult to process and control such as arc degree and arc length, and the processing cost is high

Since the frame-type composite structure comprehensive pipe gallery is made of pure steel structure and then poured with concrete, the price advantage is relatively weak in some areas where the use requirements are not high
