Technical Field

[0001] The utility model relates to the field of building construction, in particular to a segmented road-through box culvert. Background Art

[0002] When a new road is constructed under a railway, highway or urban road, the box culvert jacking construction technology is usually used. The box culvert jacking construction is to prepare the jacking box in the prefabricated work area, lay concrete and lubricating isolation layer at the bottom, remove the existing one, and then tamp and jack it up.

[0003] At present, box culverts are usually 15-18 meters long and are generally made of reinforced concrete or masonry. The required jacking force is too large. At the same time, when constructing in narrow areas, the box culvert cannot be cast due to insufficient space, which needs to be improved. Utility Model Content

[0023] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0024] like Figure 1 , Figure 2 As shown, a segmented road culvert comprises a multi-segment culvert body 1, a plug rod 2, a plug hole 3 and a locking member 4. The cross section of the culvert body 1 is a rectangular tubular arrangement, and the end faces are mutually opposed, forming a long tubular arrangement.

[0025] like Figure 1 , Figure 2 As shown, the insertion rods 2 are evenly arranged around one end of the culvert body 1, and the insertion holes 3 are evenly arranged around the other end of the culvert body 1, and the insertion rods 2 are inserted to achieve the limit of the axial direction of the adjacent culvert bodies 1, so that during the jacking process, multiple sections of the culvert body 1 move on the same straight line to prevent deviation. At the same time, the insertion of the insertion rods 2 and the insertion holes 3 can also achieve the horizontal limit and support of the adjacent culvert bodies 1, and increase the stability between the adjacent culvert bodies 1.

[0026] like Figure 1 , Figure 2 As shown, the locking member 4 is disposed between two adjacent sections of the culvert body 1 and is used to achieve the fixation between adjacent culvert bodies 1. The locking member 4 includes a bone-shaped locking plate 41, and the inner walls at both ends of the culvert body 1 are provided with locking grooves 42 for the locking plate 41 to be embedded, and the locking plate 41 is fixed in the culvert body 1 by bolts 43.

[0027] Therefore, when constructing a box culvert, by using a segmented box culvert, each section of the box culvert can be jacked in separately. The length of each section of the box culvert is relatively short and the weight is relatively light, which reduces the problem of excessive jacking force required. At the same time, it is easy to carry out construction in a small site, making the construction more convenient.

[0028] At the same time, when adjacent culvert bodies 1 are spliced ​​together, the insertion and cooperation of the insertion rod 2 and the insertion hole 3 realizes the limited fixation in the horizontal direction and the axial direction. Then, the locking plate 41 is inserted into the locking groove 42, and the bolt 43 is tightened to realize the fixation of the locking plate 41. The bone-shaped locking plate 41 is used to tighten the adjacent culvert bodies 1 to realize the fixation in the axial direction, and at the same time, the adjacent culverts are tightly connected to ensure the stability and tightness between the culvert bodies 1.

[0029] like Figure 1 , Figure 2 As shown, a wedge-shaped guide block 21 is provided at the end of the insertion rod 2 located below, the opening position of the insertion hole 3 is set in a flared shape, and has a guide slope 31 that fits with the side wall of the guide block 21, and a guide hole 32 for inserting the guide block 21 is provided at the bottom of the insertion hole 3.

[0030] When the box culvert body 1 after the second section is pushed forward, the guide block 21 is located in the front during the movement of the box culvert body 1. At this time, under the guiding action of the wedge-shaped guide block 21 and the guide slope 31, the box culvert body 1 at the rear can be automatically centered and proofread, thereby realizing rapid and precise docking between adjacent box culvert bodies 1, thereby realizing convenient construction of the box culvert.

[0031] like Figure 1 , Figure 2As shown, a sealing ring 5 is provided at one end of the culvert body 1, and a sealing groove 6 for the sealing ring 5 to be embedded is provided at the other end, so as to increase the sealing performance between adjacent culvert bodies 1 and prevent water seepage and leakage.

[0032] like Figure 1 , Figure 2 As shown, a rubber sealing ring 7 is embedded in the end face of the sealing ring 5, which further increases the sealing between adjacent culvert bodies 1. At the same time, it can form a shock-absorbing seal between adjacent culvert bodies 1, reduce the impact force between the culvert bodies 1, and can serve as an expansion joint to provide a certain buffer space for the thermal expansion and contraction of the culvert body 1.

[0033] like Figure 1 , Figure 2 As shown, a pad 8 for the top block to abut is provided at the end of the box culvert body 1, so that the hydraulic jack will not directly act on the surface of the box culvert body 1 during the jacking process, thereby preventing pressure loss on the surface of the box culvert body 1 and ensuring stable construction of the box culvert body 1.

[0034] like Figure 1 , Figure 2 As shown, a groove 9 for the top block to be embedded is provided on the pad 8, so as to fix the top block, prevent deviation or slipping, realize stable jacking of the box culvert body 1, and increase the stability and safety of the construction process.

[0035] The specific embodiments are merely explanations of the present invention and are not limitations of the present invention. After reading this specification, those skilled in the art may make modifications to the embodiments without any creative contribution as needed. However, as long as they are within the scope of the claims of the present invention, they are protected by the patent law.
