[0001] This utility model relates to the field of municipal road technology, specifically to a support structure for the construction of box culverts in municipal roads. Background Technology
[0002] Municipal roads are a core component of urban infrastructure, undertaking important functions such as traffic flow, public activities, and urban spatial division. They consist of motor vehicle lanes, non-motor vehicle lanes, sidewalks, green belts, and ancillary facilities such as streetlights, traffic signs, and drainage systems, forming a safe and efficient traffic network. As the lifeblood of urban development, municipal roads not only connect residential and commercial areas and promote economic exchange, but also enhance the city's image through rational planning. Their design must take into account traffic efficiency, flood control and drainage, and ecological environmental protection. For example, permeable pavement can be used to reduce waterlogging, or green belts can be used to reduce noise pollution. With the advancement of smart city construction, some roads have been integrated into intelligent transportation systems to achieve dynamic management and provide citizens with a more convenient travel experience.
[0003] In the existing technology, the construction of box culverts for municipal roads is an important part of urban infrastructure construction. With the acceleration of urbanization, the demand for box culvert construction is increasing. At present, the support technology for box culvert construction mainly adopts the traditional steel sheet pile support, which forms a temporary retaining structure by driving steel sheet piles. It has the advantages of fast construction speed and reusability, but it is prone to displacement in soft soil foundation. Therefore, we need a support structure for the construction of box culverts for municipal roads. Utility Model Content
[0004] The purpose of this utility model is to provide a support structure for the construction of box culverts for municipal roads, so as to solve the existing problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a support structure for the construction of a box culvert for municipal roads, comprising soil, a support component disposed within the soil, a box culvert disposed within the support component, a concrete layer disposed within the box culvert, a reinforcement component disposed within the support component, the support component comprising a concrete foundation, the concrete foundation being poured within the soil, an anchor rod fixedly connected within the concrete foundation, a bolt head fixedly connected to the top of the anchor rod, a nut threadedly connected to the outer wall of the bolt head, a sheet pile disposed on one side of the concrete foundation, a first brick-lined drainage ditch disposed on the top of the soil, and a second brick-lined drainage ditch disposed on the top of the concrete foundation.
[0006] Preferably, the anchor rod is fixed to the box culvert by means of a bolt head, and the bottom of the bolt head is fixed to the top of the anchor rod, and the top of the bolt head passes through the box culvert and is connected to the nut.
[0007] Preferably, the soil is fixed to the concrete foundation by steel sheet piles, and there are two steel sheet piles, which are installed on both sides of the concrete foundation and in contact with the soil.
[0008] Preferably, there are two second brick-built drainage ditches on the concrete foundation, and the two second brick-built drainage ditches are used for drainage inside the pit bottom.
[0009] Preferably, the reinforcement component includes a support rod, one end of which is fixedly connected to a screw, the outer wall of which is threadedly connected to a threaded sleeve, the outer wall of which is provided with a fixing frame, and one side of which is fixedly connected to a support plate.
[0010] Preferably, the fixing frame forms a threaded structure with the screw through a threaded sleeve, and the inner diameter of the threaded sleeve matches the outer diameter of the screw, and the inner wall of the threaded sleeve is fitted to the outer wall of the screw.
[0011] Preferably, the fixing frame and the support plate form a fixing structure, and there are two support plates, which are respectively attached to the steel sheet piles on both sides of the pit bottom for support and fixing.
[0012] Compared with the prior art, the beneficial effects of this utility model are: In the scheme of this application: 1. To address the problems of unstable box culvert fixation, poor drainage of foundation pit, and easy softening of soft soil in existing technologies, this application achieves stable support and overall strength enhancement for the box culvert by setting up a concrete foundation and multiple sets of anchor bolt structures. The box culvert is secured by bolt heads penetrating through the culvert and nuts, and reinforced by pouring a concrete layer, ensuring reliable fixation. At the same time, the first brick-built drainage ditch effectively drains water from both sides of the sheet piles, preventing external water from flowing into the foundation pit. In conjunction with the second brick-built drainage ditch in the foundation pit, accumulated water is drained in a timely manner, reducing the risk of soft soil softening. This design comprehensively improves the stability of the box culvert fixation, the drainage efficiency of the foundation pit, and the durability of the foundation. 2. To address the problems of inconvenient adjustment and insufficient stability of sheet pile support structures in existing foundation pit support technologies, this application utilizes a rotatable support rod in conjunction with a screw, threaded sleeve, and fixing frame structure. This achieves flexible adjustment and stable fixation of the sheet pile support spacing. Rotating the support rod causes the screw to rotate within the threaded sleeve of the fixing frame, thereby adjusting the spacing between the two fixing frames. This ensures the support plate fits tightly against the inner side of the sheet pile, enhancing support stability. This design not only improves the sheet pile's resistance to deformation but also simplifies the construction process through mechanical adjustment, effectively enhancing the safety and operational efficiency of foundation pit support.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0016] This utility model embodiment provides a support structure for the construction of box culverts in municipal roads, such as... Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the structure includes soil 1, a support component 4 inside the soil 1, a box culvert 3 inside the support component 4, a concrete layer 5 inside the box culvert 3, a reinforcement component 2 inside the support component 4, and a concrete foundation 401 poured inside the soil 1. Anchor bolts 402 are fixedly connected inside the concrete foundation 401, bolt heads 403 are fixedly connected to the top of the anchor bolts 402, and nuts 404 are threaded onto the outer wall of the bolt heads 403. Sheet piles 405 are installed on one side of the concrete foundation 401, and a first brick-built drainage ditch 406 is installed on the top of the soil 1. A second brick-lined drainage ditch 407 is provided on the top of the foundation 401. By pouring concrete foundation 401 between two sheet piles 405, the overall strength of the foundation can be improved by relying on multiple sets of anchor rods 402. At the same time, when the box culvert 3 is placed in the foundation, the bolt head 403 can penetrate the box culvert 3 and be fastened with the nut 404. Meanwhile, the concrete layer 5 is poured for reinforcement, thereby completing the fixation of the box culvert 3. In addition, by relying on the first brick-lined drainage ditch 406, drainage can be carried out on both sides of the sheet pile 405 to reduce water entering the foundation pit. At the same time, the second brick-lined drainage ditch 407 in the foundation pit can reduce the further softening of soft soil.
[0017] Further, such as Figure 4 As shown, the anchor rod 402 forms a fixed structure with the box culvert 3 through the bolt head 403, and the bottom of the bolt head 403 is fixed to the top of the anchor rod 402. The top of the bolt head 403 passes through the box culvert 3 and is connected to the nut 404. The anchor rod 402 improves the overall stability of the concrete foundation 401. At the same time, the nut 404 is fastened to the outer wall of the bolt head 403, which improves the fixing effect between the box culvert 3 and the foundation and reduces the occurrence of movement of the box culvert 3.
[0018] Further, such as Figure 2 and Figure 4 As shown, the soil 1 is fixed to the concrete foundation 401 by steel sheet piles 405, and there are two steel sheet piles 405. The two steel sheet piles 405 are installed on both sides of the concrete foundation 401 and are in contact with the soil 1. The two steel sheet piles 405 can be used to support the soil on both sides and form the foundation pit space, which improves the stability of the support.
[0019] Further, such as Figure 2 and Figure 4 As shown, there are two second brick drainage ditches 407 on the concrete foundation 401, and the two second brick drainage ditches 407 are used for drainage inside the pit bottom. The second brick drainage ditches 407 can be used for drainage inside the foundation pit, and the drainage at both locations can reduce the situation of soft soil continuing to soften.
[0020] In a further preferred embodiment of this utility model, such as Figure 1 and Figure 3 As shown, the reinforcement component 2 includes a support rod 201. One end of the support rod 201 is fixedly connected to a screw rod 202. The outer wall of the screw rod 202 is threadedly connected to a threaded sleeve 203. A fixing frame 204 is provided on the outer wall of the threaded sleeve 203. A support plate 205 is fixedly connected to one side of the fixing frame 204. By digging a foundation pit in the soil 1 and placing the sheet piles 405 against one side of the soil 1, the support rod 201 is used to support the sheet piles 405. Rotating the support rod 201 allows the screw rod 202 to rotate, allowing the screw rod 202 to rotate within the threaded sleeve 203 in the fixing frame 204. This allows the spacing between the fixing frames 204 at both ends of the support rod 201 to be adjusted. At the same time, the fixing frames 204 on both sides can be fixed to the inside of the sheet piles 405 by the support plates 205 on both sides, which improves the support stability of the sheet piles 405.
[0021] Further, such as Figure 3As shown, the fixing bracket 204 forms a threaded structure with the screw 202 through the threaded sleeve 203, and the inner diameter of the threaded sleeve 203 matches the outer diameter of the screw 202. The inner wall of the threaded sleeve 203 is fitted to the outer wall of the screw 202, which enhances the connection between the threaded sleeve 203 and the screw 202. This allows the screw 202 to rotate within the threaded sleeve 203, and the distance between the two fixing brackets 204 can be adjusted.
[0022] Further, such as Figure 3 As shown, the fixing frame 204 and the support plate 205 form a fixed structure, and there are two support plates 205. The two support plates 205 are respectively attached to the steel sheet piles 405 on both sides of the pit bottom for support and fixation, which strengthens the connection effect between the fixing frame 204 and the support plate 205. When the spacing of the two fixing frames 204 is adjusted, the support plates 205 on both sides can drive the steel sheet piles 405 on both sides inside the pit to support them. The layer-by-layer excavation and support method can also further improve the overall strength.
[0023] Working principle: In use, a foundation pit is dug into the soil 1, and the sheet piles 405 are placed against one side of the soil 1. Support rods 201 are used to support the sheet piles 405. Rotating the support rods 201 causes the screw rods 202 to rotate, allowing the screw rods 202 to rotate within the threaded sleeves 203 of the fixing frames 204. This allows for adjustment of the spacing between the fixing frames 204 at both ends of the support rods 201. Simultaneously, the fixing frames 204 on both sides are fixed to the inside of the sheet piles 405 by the support plates 205 on both sides. The support stability of the sheet piles 405 is improved. In addition, by pouring a concrete foundation 401 between the two sheet piles 405, the overall strength of the foundation can be improved by relying on the multiple sets of anchor rods 402. At the same time, when the box culvert 3 is placed in the foundation, the bolt head 403 can penetrate the box culvert 3 and be fastened with the nut 404. At the same time, the concrete layer 5 is poured for reinforcement, thereby completing the fixation of the box culvert 3. In addition, by relying on the first brick drainage ditch 406, drainage can be carried out on both sides of the sheet piles 405 to reduce water entering the foundation pit. Meanwhile, the second brick drainage ditch 407 in the foundation pit can reduce the further softening of the soft soil.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
