Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of civil engineering, and in particular to a construction shed for foundation pit box culverts. Background Technology
[0002] A box culvert is a foundation pit excavated in civil engineering for the construction of a box culvert (a type of pipe structure). A box culvert is a pipe structure used to cross roads, rivers, or other obstacles, typically composed of precast concrete boxes. The construction of a box culvert involves first excavating a suitable foundation pit underground, then placing the box culvert within the pit and securing and connecting it to meet subsequent drainage requirements.
[0003] Currently, the main way to avoid the heat during outdoor construction in the engineering field in summer is to adjust the working hours and avoid working at noon. However, workers still face the scorching sun at other times. Most drainage culvert construction projects are linear projects with narrow and long construction sites. Traditional construction sunshades are prone to being blown away or overturned in windy weather. Utility Model Content
[0004] To address the risks of traditional construction sunshades being blown away or overturned in strong winds, this invention provides a construction shed for foundation pit box culverts.
[0005] This utility model provides a construction shed for foundation pit box culverts, adopting the following technical solution:
[0006] A construction shed for a foundation pit box culvert includes a foundation pit. Both the front and rear ends of the top of the foundation pit are equipped with foundation pit guardrails. Steel wires are intersecting between the two sets of foundation pit guardrails. The ends of the steel wires are magnetically connected to the foundation pit guardrails through steel wire end magnets. The bottom of the steel wires is connected to a dense mesh net.
[0007] By adopting the above technical solution, two intersecting steel wires are installed diagonally across the existing foundation pit guardrail. The two steel wires are attached to the foundation pit guardrail by magnets at their four ends, thus fixing the two steel wires in place. At the same time, the bottoms of the two steel wires are fixed to the four corners of the dense mesh netting, so that the dense mesh netting covers the intersecting steel wires. The dense mesh netting provides shade and rain protection for the workers working below, solving the problem of construction being impossible in the open air during rainy days for foundation pit box culvert construction. This greatly reduces the impact of rain on the construction progress and avoids economic losses caused by idle personnel and machinery. When it is necessary to change the position of the dense mesh netting, simply remove the magnets at the ends of the steel wires and move the device to the area requiring shade and rain protection for reuse, making the overall assembly and disassembly of the dense mesh netting more convenient.
[0008] Optionally, two steel wires are provided, and the two ends of the two steel wires are respectively fixedly connected to the four corners of the dense mesh.
[0009] By adopting the above technical solution, the dense mesh is ensured to be higher in the middle and lower around the edges, preventing water accumulation and making the structure safer and more reliable.
[0010] Optionally, the pit guardrail includes four horizontal posts, which are symmetrically distributed in pairs about the center of the pit. Each of the four horizontal posts has several vertical posts inserted inside it, and the four vertical posts are magnetically connected to the ends of two steel wires respectively.
[0011] By adopting the above technical solution, the device can be directly attached to the post of the foundation pit guardrail at the edge of the foundation pit using the magnet at the end of the steel wire. When moving, the magnet at the end of the steel wire can be pulled off the post to move to the next construction area.
[0012] Optionally, all four wire end magnets are neodymium iron boron magnets.
[0013] By adopting the above technical solution, the attraction force of the wire end magnets is strengthened, thereby ensuring a more secure connection between the four wire end magnets and the column.
[0014] Optionally, the surface of the dense mesh is coated with an oil-based waterproofing agent.
[0015] By adopting the above technical solution, oil-based waterproofing agents can effectively prevent water from penetrating into the foundation pit, which can greatly avoid the impact of rainy weather on the construction progress.
[0016] Optionally, the surfaces of the steel wire and the wire-end magnet are coated with a paint layer.
[0017] By adopting the above technical solution, the steel wire and the steel wire end magnet are effectively isolated from water and oxygen, thereby preventing the steel wire and the steel wire end magnet from rusting and corroding, and thus extending the service life of the steel wire and the steel wire end magnet.
[0018] In summary, this utility model has at least one of the following beneficial effects:
[0019] By combining the foundation pit guardrail, steel wire, and dense mesh netting, the dense mesh netting can provide shade and shelter from rain for the workers working below during the hot summer. Because the dense mesh netting has a porous structure, the construction shed still has good stability in windy weather and will not be damaged or blown away by strong winds.
[0020] By using the four wire end magnets in conjunction, the mesh can be directly attached to the posts along the edge of the foundation pit. When moving, the wire end magnets can be removed from the posts to move to the next construction area, making the mesh easy to assemble and disassemble. At the same time, by using neodymium iron boron magnets, the attraction force of the wire end magnets is stronger, thus ensuring a more secure connection between the four wire end magnets and the posts.
[0021] By using two steel wires in a crisscross pattern, ensuring that the middle of the wires is higher than the surrounding area, the dense mesh will not accumulate water, making the structure safer and more reliable.
[0022] By spanning the foundation pit with dense mesh netting and coating the surface of the mesh with an oil-based waterproofing agent, rainwater can be prevented from entering the foundation pit, and the slope of the foundation pit can be prevented from being eroded by rainwater, thus greatly enhancing the safety of the foundation pit.

[0028] The following is in conjunction with the appendix Figures 1-3 The present invention will be described in further detail below.
[0029] Please refer to the attached diagram in the instruction manual. Figure 1 and Figure 2 This utility model provides an embodiment of a foundation pit box culvert construction shed, comprising a foundation pit 1. Foundation pit guardrails 2 are installed at both the front and rear ends of the top of the foundation pit 1. Steel wires 3 are intersecting between the two sets of foundation pit guardrails 2. The ends of the steel wires 3 are magnetically connected to the foundation pit guardrails 2 via steel wire end magnets 4. The foundation pit guardrails 2 include four horizontal posts 202, symmetrically distributed in pairs around the center of the foundation pit 1. Several vertical posts 201 are inserted inside each of the four horizontal posts 202, and each of the four vertical posts 201 is magnetically connected to the ends of two steel wires 3. The device can be directly attached to the vertical posts 201 of the foundation pit guardrail 2 along the edge of the foundation pit 1 using the steel wire end magnets 4. When moving, the steel wire end magnets 4 can be removed from the vertical posts 201 to move to the next construction area.
[0030] Please refer to the attached diagram in the instruction manual. Figure 1 and Figure 2 All four wire end magnets 4 are neodymium iron boron magnets. This makes the attraction force of the wire end magnets 4 stronger, thus ensuring a more secure connection between the four wire end magnets 4 and the column 201.
[0031] Please refer to the attached diagram in the instruction manual. Figure 1 , Figure 2 and Figure 3 The bottom of the steel wire 3 is connected to a dense mesh net 5. There are two steel wires 3, and the two ends of the two steel wires 3 are fixedly connected to the four corners of the dense mesh net 5. This ensures that the dense mesh net 5 is higher in the middle and lower around the edges, preventing water accumulation and making the structure safer and more reliable.
[0032] Please refer to the attached diagram in the instruction manual. Figure 1 and Figure 3 Both the steel wire 3 and the magnet at the end of the wire 4 are coated with a layer of paint. This effectively isolates the steel wire 3 and the magnet at the end of the wire 4 from contact with water and oxygen, thus preventing rust and corrosion and extending their service life. The surface of the dense mesh 5 is coated with an oil-based waterproofing agent. This oil-based waterproofing agent effectively prevents moisture from penetrating into the foundation pit, greatly minimizing the impact of rain on the construction progress.
[0033] Working principle: In use, two intersecting steel wires 3 are installed diagonally across the existing pit guardrail 2 of pit 1. The two steel wires 3 are attached to the posts 201 of the pit guardrail 2 via magnets 4 at their four ends, thus fixing the two steel wires 3 in place. Simultaneously, the bottoms of the two steel wires 3 are fixed to the four corners of the dense mesh netting 5, ensuring the dense mesh netting 5 covers the intersecting steel wires 3. By applying an oil-based waterproofing agent to the surface of the dense mesh netting 5, it achieves waterproofing and rainproofing, providing shade and protection from rain for workers constructing below during hot summers, while also preventing rainwater from entering the pit 1. To prevent the slope of foundation pit 1 from being eroded by rainwater, the safety of foundation pit 1 is greatly enhanced. Due to the porous structure of the dense mesh, the construction shed still has good stability in windy weather and will not be damaged or blown away by strong winds. When it is necessary to change the position of the dense mesh 5, simply remove the wire end magnet 4 and move the device to an area that needs shade and rain protection for reuse. This makes the overall disassembly and assembly of the dense mesh 5 more convenient. In addition, the wire end magnet 4 is made of neodymium iron boron magnet, which makes the attraction force of the wire end magnet 4 stronger, thereby ensuring that the connection between the four wire end magnets 4 and the column 201 is more secure.
[0034] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
