Abstract
Description
Technical Field
[0001] The utility model belongs to the field of box culverts, and in particular relates to a thermal pipeline box culvert structure that resists floating. Background Art
[0002] A box culvert is a culvert constructed with reinforced concrete box sections. It consists of one or more square or rectangular sections, typically made of reinforced concrete or masonry. When thermal pipelines cross rivers, they are often protected by box culverts. To prevent longitudinal instability, the box culverts are filled with sand. However, this sand is easily washed away, causing pipeline instability and compromising system safety. Utility Model Content
[0003] The utility model aims to provide a thermal pipeline box culvert structure that resists floating, so as to solve the problem that the thermal pipeline is prone to longitudinal instability.
[0004] The technical solution of the utility model is: a thermal pipe box culvert structure that resists floating, including a box body enclosed by a bottom plate, side walls and a cover plate, with piers provided on the bottom plate, pipes provided on the piers, and prefabricated beams detachably provided on the top of the pipes, the prefabricated beams abutting against the pipes, and the two sides of the prefabricated beams detachably connected to the side walls.
[0005] As a further improvement of the present invention, the cover plate is movably arranged on the side wall.
[0006] As a further improvement of the present invention, the side walls on both sides are respectively provided with a first card slot and a second card slot, the second card slot is deeper than the first card slot, the two sides of the prefabricated beam are respectively located in the first card slot and the second card slot, and a pin is provided on the prefabricated beam, which abuts against the side wall at the second card slot.
[0007] As a further improvement of the present invention, a placement groove is provided on the upper surface of the pier, and the pipeline is placed in the placement groove.
[0008] As a further improvement of the present invention, a semicircular upper slide plate and a lower slide plate are provided in contact with the outer wall of the pipeline, and the upper slide plate and the lower slide plate are connected by bolts.
[0009] The beneficial effects of this utility model are as follows: The utility model provides a prefabricated beam at the top of the pipeline, clamping the pipeline between the support pier and the prefabricated beam, thereby preventing longitudinal instability of the pipeline. Both the cover plate and the prefabricated beam in this utility model are removable, facilitating subsequent maintenance. This utility model has a simple structure and is easy to install. It does not require sand filling, thus avoiding instability caused by sand filling being washed away, and is highly practical. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] The present invention will be described in detail below with reference to the accompanying drawings.
[0013] like Figure 1 As shown, a thermal pipe box culvert structure that resists uplift includes a box body enclosed by a bottom plate 1, side walls 7 and a cover plate 6. A pier 2 is provided on the bottom plate 1, and a pipe 4 is provided on the pier 2. A prefabricated beam 9 is detachably provided on the top of the pipe 4, and the prefabricated beam 9 is abutted against the pipe 4. The two sides of the prefabricated beam 9 are detachably connected to the side walls 7.
[0014] The cover plate 6 is movably arranged on the side wall 7 .
[0015] The side walls 7 on both sides are respectively provided with a first slot 71 and a second slot 72 , the second slot 72 being deeper than the first slot 71 , and the two sides of the prefabricated beam 9 are respectively located in the first slot 71 and the second slot 72 , and the prefabricated beam 9 is provided with a latch 10 , which rests on the side wall 7 at the second slot 72 .
[0016] A placement groove 21 is provided on the upper surface of the pier 2 , and the pipe 4 is placed in the placement groove 21 .
[0017] A semicircular upper slide 11 and lower slide 12 are provided on the outer wall of the pipe 4 and are connected by bolts. The upper and lower slides 11 and 12 act as lubricants, accommodating axial displacement of the pipe due to thermal expansion and contraction, thus changing the traditional sand filling lubrication method and simplifying the process.
[0018] The unit node of the box is 2.5 meters. Piers 2 are set every 5 meters.
[0019] During construction, a bottom plate 1 is set in the excavated trench, the steel bars of the bottom plate 1 and the steel bars of the side walls 7 are tied together, and the concrete of the bottom plate 1 is poured in blocks; then the concrete of the pier 2 is poured, and the concrete of the side walls 7 is poured in sections; after the concrete reaches the design strength, the pipe 4 is placed in the placement groove 21 of the pier 2, and the precast beam 9 is installed. First, one end of the precast beam 9 is inserted into the second slot 72, and then the other end of the precast beam 9 is aligned with the first slot 71, inserted into the first slot 71 and pressed tightly, and the pin 10 is inserted into the precast beam 9 to prevent it from moving laterally and falling; finally, the cover plate 6 is covered, and the stone slab 5 is constructed on the cover plate 6.
[0020] The precast beam 9 clamps the pipe 4 between the pier 2 and the precast beam 9 to prevent the pipe 4 from longitudinally destabilizing due to thermal stress. The cover plate 6 and the precast beam 9 in the present invention are both detachable, which is convenient for later maintenance.
