Problems solved by technology

[0003] 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 Pipe frame and pipeline arrangement; ③. For integral circular cross-section pipes, there are difficulties in transportation, and the pipe diameter will exceed 3.5 meters; It is an arc-shaped structure. When stacking and transporting, the higher the stack, the more the plates will be stressed during the transportation process, which will easily cause inestimable arc deformation of the plates. In severe cases, they cannot be docked and assembled when transported to the site, and need to be reworked; ⑤. Compared with straight plates, arc-shaped plates are difficult to process and control such as arc length and arc length, and the processing costs are high; ⑥. The cross-section of rectangular pipes can simply change the aspect ratio to meet different floor height requirements; ⑦. Compared with circular cross-section pipes, rectangular cross-section pipes are less difficult to construct; ⑧. The flexibility of curved unit plates is greater than that of straight unit plates; However, for the urban underground comprehensive pipe gallery, when the deformation of the pipe is too large, it may cause deformation or damage to the pipe rack and pipeline inside the pipe gallery; ⑩, according to the standard of the Ministry of Housing and Urban- According to the 2015 standard of Technical Specifications for Corridor Engineering, the circular pipe gallery has a low space utilization rate compared with the box-shaped pipe gallery, and the circular pipe gallery only uses the rectangular clearance space inside the circular pipe gallery; The height of the circular pipe gallery is higher than that of the box-shaped pipe gallery, and it needs to be buried deeper, which increases the excavation depth and engineering volume of the foundation
[0004] The applicant has applied for an invention patent with the application number 2016102374785 "Integrated Pipe Gallery of Frame-type Composite Structure". Poured concrete, the price advantage is relatively weak in some areas where the use requirements are not high

Embodiment 1

[0050] Such as figure 1 As shown, a high-strength urban underground comprehensive pipe gallery of the present invention includes a box-shaped pipe joint 104 assembled from a top plate 101, a bottom plate 102, and two side plates 103. Specifically, welding, flange connection or hidden bolt connection can be used. connection method. The box-shaped pipe joint 104 is rectangular. At the same time, the box-shaped pipe joint 104 can be as long as 15 to 25 meters. As long as the transportation conditions permit, the length can be longer, so that the joints of the entire pipe gallery are reduced and the sealing performance is better; the obtained box The pipe joints 104 are assembled in the axial direction to form a high-strength urban underground comprehensive pipe gallery 100, and adjacent box-shaped pipe joints 104 are connected by welding, flange connection or hidden bolts.

Embodiment 2

[0060] Such as figure 2 As shown, the structure of embodiment 2 is basically the same as that of embodiment 1, the difference is that: the side plate 103 is a straight corrugated plate, and the direction of the arched pattern is consistent with the extending direction of the column. The corrugated steel web bridge principle is used for the side panels whose pattern direction is consistent with the direction of the column in the comprehensive pipe corridor. The pressure has been greatly increased.

Embodiment 3

[0062] Such as image 3 As shown, the structure of embodiment 3 is basically the same as that of embodiment 1, the difference is that the side plate 103 is a straight corrugated plate, and the direction of its arching pattern is consistent with the extending direction of the pipe gallery. The plate with protrusions adopts the principle of large moment of inertia. The principle of large moment of inertia is to form a straight plate into a plate with a raised structure in section, so that its section moment of inertia is greatly improved, and it is resistant to bending, torsion and deformation. The capacity is significantly improved, and then the load-carrying capacity of the plate is greatly improved compared with the flat plate, and the degree of performance improvement depends on the shape and size of the protrusions.

Abstract

The invention discloses a high-strength urban underground comprehensive pipe gallery. The high-strength urban underground comprehensive pipe gallery is characterized in that a top plate, a base plate and two side plates consisting of corrugated plates of which the outer sides and / or the inner sides are provided with protrusions are spliced to form a box-type pipe joint; the box-type pipe joints are spliced in the axial direction to form the comprehensive pipe gallery, wherein longitudinal beams are arranged at edges of the box-type pipe joints; cross beams are arranged at two ends of the top plates and / or the base plates in the axial direction of the box-type pipe joints; upright posts are arranged at two ends of the side plates; the cross beams and the upright posts are connected end to end to form a frame type framework; the top plates are arched; the direction of arched grains on the top plates are consistent with the extending direction of the pipe gallery; the top plates and the cross beams at two ends are combined to form a structure; the top plates apply the principles of joint stress of pipe and soil and a continuous arch bridge, and sheets of the top plates and backfill soil are collaboratively stressed; in addition, the direction of the arched grains on the sheets is consistent with the extending direction of the pipe gallery; in addition, the cross beams are arranged between adjacent top plates side by side in the extending direction of the pipe gallery; and except the cross beams at two ends of the pipe gallery, horizontal components of the top plates on the cross beams are offset leftwards and rightwards, so the bearing capacity of an overall structure is higher.
