Description

Technical Field

[0001] This utility model relates to the field of pipe culvert bridge technology, specifically to a modular pipe culvert bridge. Background Technology

[0002] A pipe culvert bridge is a type of bridge laid in the middle of a canal or river, primarily suitable for small to medium-sized waterways. The construction process typically involves first cutting off the waterway, then placing a pipe at the appropriate location within the waterway, filling the area around the pipe with sand or concrete, and finally constructing a road over the fill. The pipes used in pipe culverts are generally concrete pipes or corrugated metal pipes. Currently, pipe joint connections often use two flanges, a gasket, and multiple sets of bolts for assembly, resulting in high connection costs and time-consuming processes, leading to a poor user experience.

[0031] Construction precautions for culvert bridge projects

[0032] (1) First, clear the site and implement the necessary infrastructure (water, electricity, road access, and leveling). Any old or dilapidated buildings that need to be demolished must be removed in advance, and construction waste must be transported to designated locations. The site should be rationally laid out to ensure smooth construction.

[0033] (2) If there is water in the river or canal, a dam must be built to drain it. If the depth of the foundation pit exceeds 3 meters, a well must be arranged. If the foundation is shallow, a deep ditch can be used for drainage.

[0034] (3) Strictly control the quality of building materials. The quality of building materials such as sand, stone, steel, and cement should meet the requirements of engineering specifications. Mix proportion tests should be conducted on mortar and concrete in advance.

[0035] (4) Construction layout must be precise and meet the requirements of construction specifications. Positioning stakes and elevation stakes must be protected and must not be bumped or moved.

[0036] (5) The excavated soil from the foundation pit should be stockpiled according to the plan. For soil that needs to be backfilled, suitable soil should be selected and stockpiled in a concentrated manner.

[0037] (6) Strict quality monitoring must be carried out during construction, including monitoring construction elevation and design dimensions, to ensure that the project is carried out according to the design drawings.

[0038] The working principle and process of this utility model are as follows: During use, after dam drainage and site leveling, dry-field operations are carried out. On-site construction is conducted according to the design drawings. Four retaining walls 160 are hoisted to the designated positions. Pipe bases 110 are placed on the toothed feet of the retaining walls 160. Flat-end socket reinforced concrete pipes 120 are hoisted onto the pipe bases 110. Four adjusting modules 150 are reinforced and connected to the four retaining walls 160 respectively. Four wing-shaped modules 140 are connected to the four retaining walls 160. Finally, two wedge-shaped modules 130 are inserted between the four wing-shaped modules 140 respectively. After the culvert bridge is assembled, the middle section is covered with soil and compacted to a compaction degree of not less than 0.93. The bridge deck is paved with plain soil, gravel, or a 5-10cm cast-in-place concrete road. When it is necessary to adjust the flat-end socket reinforced concrete pipe... When connecting the 120mm pipe sections, hot asphalt-impregnated hemp fiber 170 is filled into the joint, half inside and half outside the pipe. It should not be filled completely from the outside at once. Finally, hot first fully coated asphalt felt 180 is wrapped around the joint, and second fully coated asphalt felt 190 is wrapped around the first fully coated asphalt felt 180. After the asphalt-impregnated hemp fiber 170, the first fully coated asphalt felt 180, and the second fully coated asphalt felt 190 have cooled, the connection between the plain-end socket reinforced concrete pipes 120 is achieved. This prefabricated pipe culvert bridge uses asphalt-impregnated hemp fiber 170, the first fully coated asphalt felt 180, and the second fully coated asphalt felt 190 to achieve the connection between the plain-end socket reinforced concrete pipes 120. It is low-cost and saves time in connection, bringing a better user experience.

[0039] The embodiments of this utility model have been described in detail above, but the content described is only a preferred embodiment of this utility model and should not be considered as limiting the scope of implementation of this utility model. All equivalent changes and improvements made within the scope of this utility model should still fall within the scope of this patent.
