Description

Technical Field

[0001] This utility model belongs to the field of road engineering construction technology, and relates to road drainage construction, specifically a permanent and temporary combined construction structure for road drainage. Background Technology

[0002] During road construction, the drainage system needs to be set up in two phases: the first is temporary drainage during the construction period, which needs to quickly drain rainwater and seepage water from the construction area and foundation pit to avoid affecting the quality and schedule of roadbed construction; the second is permanent drainage during the operation period, which needs to meet the drainage needs of long-term road use and ensure the stability of the road surface structure and traffic safety.

[0003] Traditional road drainage construction often uses low-cost materials such as simple PVC pipes and brick-built drainage ditches for temporary drainage, which only meet short-term needs and do not meet the standards for permanent drainage in terms of strength, pipe diameter, and slope. After road completion, these temporary facilities must be completely dismantled and abandoned, generating a large amount of construction waste and requiring the road surface to be excavated and permanent drainage pipes to be laid, resulting in high repeated costs. The laying paths and interface designs of temporary drainage facilities and permanent drainage pipes are completely independent, and the location of temporary pipes may conflict with that of permanent pipes during construction. When dismantling temporary facilities and excavating the road surface to lay permanent pipes after completion, the already formed roadbed or base structure is easily damaged, leading to quality problems such as road surface settlement and cracking in the later stages. Utility Model Content

[0004] This utility model provides a permanent-temporary combined construction structure for road drainage, which has the advantages of reducing resource waste and repeated construction, and solves the problems of high repeated investment costs and easy damage to the construction structure during later demolition of existing construction structures.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A combined permanent and temporary construction structure for road drainage includes a ground surface and a main pipeline trench located in the middle of the ground surface. It also includes a main pipeline assembly, a switchable drainage interface assembly, a temporary drainage assembly, and a temporary reinforcement assembly. Road drainage outlets are located on both sides of the main pipeline trench, and these outlets are connected to the main pipeline trench via pre-embedded concrete pipes. A gravel cushion layer is laid at the bottom of the main pipeline trench. The main pipeline assembly includes several main pipelines connected by a socket-type connection at the pipe ends. The outer side of each main pipeline is wrapped with a polyethylene geomembrane, and a drainage groove is formed at the bottom of the inner wall of each main pipeline. The switchable drainage interface assembly and the temporary drainage assembly are symmetrically arranged on both sides of the main pipeline. The temporary reinforcement assembly is located between the main pipeline and the gravel cushion layer. The switchable drainage interface assembly includes a temporary interface, a permanent interface, and a reserved opening. The reserved opening is located on both sides of the main pipeline. The permanent interface has socket-type interface grooves at both ends, and rubber sealing rings are fitted around the socket-type interface grooves.

[0006] Preferably, one end of the permanent interface is fitted with a reserved opening, and the other end is fitted with a concrete pipe. The temporary interface adopts a PVC flange interface, and one end of the PVC flange interface is pre-embedded and fixed on both sides of the main pipeline.

[0007] Preferably, the temporary drainage assembly includes a sump, a temporary drainage ditch, a branch ditch, a short PVC pipe, and a detachable flange pipe.

[0008] Preferably, the temporary drainage ditch is symmetrically arranged on both sides of the main pipeline ditch and has a certain drainage slope with it, and the water collection well is arranged at both ends of the temporary drainage ditch and is interconnected with it.

[0009] Preferably, the branch trench is located between the water collection well and the main pipeline trench, and the short PVC pipe is located in the branch trench with one end connected to the water collection well and the other end connected to a temporary interface through a detachable flange pipe.

[0010] Preferably, the temporary reinforcement assembly includes an arc-shaped fixing plate, a screw, a rotatable screw cylinder, and an angle steel bracket. The arc-shaped fixing plate is symmetrically attached to both sides of the main pipeline and fixed at both ends by bolts.

[0011] Preferably, the upper end of the screw is welded with an arc-shaped fixing plate located below, and the bottom end is fitted with a rotatable screw cylinder that rotates spirally. The bottom of the rotatable screw cylinder is fitted with an angle steel bracket that rotates, and the angle steel bracket is fixed to the gravel pad layer by expansion bolts.

[0012] Compared with the prior art, the present invention has the following beneficial effects: The main pipeline of this structure can be directly reused from temporary drainage during the construction phase as permanent drainage facilities during the operation phase. Unlike traditional structures, it eliminates the need to dismantle temporary PVC pipes and brick drainage ditches and then excavate and lay permanent pipelines. This reduces the amount of construction waste and saves the dual costs of dismantling temporary facilities and rebuilding permanent facilities. Furthermore, the detachable flange pipes only require removal and sealing of the joints after construction, further reducing waste of temporary facilities and controlling overall construction costs. During the construction phase, the main pipeline is laid according to the permanent drainage slope. During the operation phase, the permanent joints are directly used to connect to the storm drains and municipal pipe network, eliminating the need for secondary road excavation. Additionally, the temporary reinforcement components can be removed later, leaving only the main pipeline and trench. This completely avoids the damage to the existing roadbed caused by the removal of temporary facilities and the excavation and laying of permanent pipelines in traditional structures, fundamentally reducing quality problems such as road surface settlement and cracking in the later stages.

[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. Example 1

[0016] like Figure 1 As shown, a combined permanent and temporary construction structure for road drainage includes a ground surface 1 and a main pipe trench 2 located in the middle of the ground surface 1. It also includes a main pipe assembly 3, a switchable drainage interface assembly 4, a temporary drainage assembly 5, and a temporary reinforcement assembly 6, wherein: like Figure 2 As shown, road drainage outlets 11 are provided on both sides of the main pipeline trench 2. The road drainage outlets 11 are connected to the main pipeline trench 2 through pre-embedded concrete pipes 12. A crushed stone cushion layer 21 is laid at the bottom of the main pipeline trench 2. Main pipe component 3, such as Figure 3 As shown, it includes several main pipes 31, which are connected by pipe end sockets. The outer side of the main pipes 31 is wrapped with a polyethylene geomembrane 32, and a drainage groove 33 is provided at the bottom of the inner wall of the main pipes 31. The polyethylene geomembrane 32 wrapped around the outside of the main pipeline 31 can prevent water from immersing the pipeline in the trench 2 during the construction period, and can prevent rainwater from seeping into the roadbed during the operation period, thus improving the stability of the road structure. The inner diameter of the main pipeline 31 is much larger than that of the drainage main pipe designed under the constraint of cost for temporary drainage facilities. In the event of heavy rain, it can smoothly accelerate drainage, avoid water accumulation in the construction area, and avoid delaying the construction progress.

[0017] Switchable drainage interface assembly 4, such as Figure 4 and Figure 5 As shown, the system includes a temporary interface 41, a permanent interface 42, and a reserved opening 43. The reserved opening 43 is located on both sides of the main pipeline 31. The permanent interface 42 has socket-type interface grooves 421 at both ends, and rubber sealing rings 422 are fitted on the outside of the socket-type interface grooves 421. One end of the permanent interface 42 is fitted into the reserved opening 43, and the other end is fitted into the concrete pipe 12. The temporary interface 41 adopts a PVC flange interface, and one end of the PVC flange interface is pre-embedded and fixed on both sides of the main pipeline 31.

[0018] Temporary drainage component 5, such as Figure 1 and Figure 6 As shown, the system includes a water collection well 51, a temporary drainage ditch 52, a branch ditch 53, a short PVC pipe 54, and a detachable flange pipe 55. The temporary drainage ditch 52 is symmetrically arranged on both sides of the main pipe ditch 2 and has a certain drainage slope with it. The water collection well 51 is located at both ends of the temporary drainage ditch 52 and is interconnected with it. The branch ditch 53 is located between the water collection well 51 and the main pipe ditch 2. The short PVC pipe 54 is located in the branch ditch 53 and one end is connected to the water collection well 51. The other end is connected to the temporary interface 41 through the detachable flange pipe 55.

[0019] During construction, rainwater and seepage from the foundation pit collect in the temporary drainage ditch 52, forming water accumulation. Under the slope of the drainage ditch 52, the water quickly flows into the collection well 51. The water in the collection well 51 is discharged through the short PVC pipe 54, and finally flows into the main pipe 31 through the detachable flange pipe 55. Finally, it is quickly drained through the drainage groove 33, forming a temporary drainage system.

[0020] In this embodiment, the permanent interface 42 is wrapped with a protective sleeve during the construction period and directly connected to the municipal pipe network and road storm drain during the operation period without the need to excavate the interface again. At the same time, the temporary reinforcement component 6 can be removed, leaving only the main pipe 31 and the main pipe trench 2 as permanent facilities for later pipe laying. This avoids the damage to the already formed roadbed structure caused by the removal of temporary facilities and the excavation of the road surface to lay permanent pipes after completion, which could lead to quality problems such as road surface settlement and cracking in the later stage. Example 2

[0021] Based on the above embodiment one, the temporary reinforcement component 6 is set between the main pipeline and the crushed stone cushion layer. The temporary reinforcement component 6, such as... Figure 7 As shown, it includes an arc-shaped fixing plate 61, a screw 62, a rotatable screw barrel 63, and an angle steel bracket 64. The arc-shaped fixing plate 61 is symmetrically attached to both sides of the main pipe 31 and fixed at both ends by bolts.

[0022] The upper end of the screw 62 is welded with an arc-shaped fixing plate 61 located below, and the bottom end is fitted with a rotatable screw cylinder 63 and rotates in a spiral manner. The bottom of the rotatable screw cylinder 63 is fitted with an angle steel bracket 64 and rotates in a spiral manner. The angle steel bracket 64 is fixed to the gravel pad layer 21 by expansion bolts.

[0023] The gravel cushion layer 21 laid at the bottom of the main pipeline trench 2 can prevent the support points of the main pipeline 31 from settling, which would cause changes in the pipeline slope and affect the drainage effect.

[0024] In this embodiment, when the main pipeline 31 is installed in the main pipeline trench 2, the arc-shaped fixing plate 61 is used in conjunction with bolts to limit and fix the main pipeline 31 on the outer periphery. After the angle steel bracket 64 is fixed to the crushed stone pad layer 21, the rotatable screw cylinder 63 and the screw 62 welded on the arc-shaped fixing plate 61 have a spiral action, thereby generating relative displacement to complete the height adjustment of the main pipeline 31 and adjust the laying slope of the pipeline.

[0025] The working principle and usage process of this utility model are as follows: First, during the roadbed construction stage, a trench is excavated to form the main pipeline trench 2 with a permanent drainage slope of 0.4%. When installing the main pipeline 31 in the main pipeline trench 2, the arc-shaped fixing plate 61 is used in conjunction with bolts to limit and fix the main pipeline 31 on the outer periphery. After the angle steel bracket 64 is fixed to the crushed stone cushion layer 21, the rotatable and spindleable screw cylinder 63 and the screw 62 welded on the arc-shaped fixing plate 61 will have a spiral action, thereby generating relative displacement to complete the height adjustment of the main pipeline 31 and adjust the laying slope of the pipeline. The gravel cushion layer 21 laid at the bottom of the main pipeline trench 2 can prevent the support point of the main pipeline 31 from settling, which would cause the pipeline slope to change and affect the drainage effect. The polyethylene geomembrane 32 wrapped around the outside of the main pipeline 31 can prevent the pipeline from being soaked by water accumulation in the main pipeline trench 2 during the construction period, and can prevent rainwater from seeping into the roadbed during the operation period, thus improving the stability of the road structure. During construction, rainwater and seepage from the foundation pit collect in the temporary drainage ditch 52, forming stagnant water. Due to the slope of the drainage ditch 52, the water quickly flows into the collection well 51. The stagnant water in the collection well 51 is discharged through the short PVC pipe 54 and finally flows into the main pipe 31 through the detachable flange pipe 55. Finally, it is quickly drained through the drainage groove 33, forming a temporary drainage system. The inner diameter of the main pipe 31 is much larger than that of the temporary drainage facility, which is designed to be within cost constraints. In case of heavy rain, it can smoothly accelerate drainage, avoid water accumulation in the construction area, and avoid delaying the construction progress. During the construction period, the detachable flange pipe 55 is connected to the PVC flange interface of the temporary interface 41 by bolts to meet the temporary drainage needs. After the road is completed, the detachable flange pipe 55 is removed, and the temporary interface 41 is sealed with a new sealing cap, which reduces the amount of waste generated by the construction of temporary drainage pipes and controls costs. After the road is completed, rainwater from the road surface flows into the road drainage outlet, and then flows into the main pipe 31 through the concrete pipe 12 with the permanent interface 42 to complete the drainage. The joint of the permanent interface 42 adopts a socket-type interface groove 421 that fits into each other and is sealed with a rubber sealing ring 422, which meets the sealing standards of the permanent drainage pipe. During the construction period, it is wrapped with a protective sleeve. During the operation period, it is directly connected to the municipal pipe network and the road rainwater outlet, without the need to excavate the interface again. At the same time, the temporary reinforcement component 6 can be removed, and only the main pipe 31 and the main pipe trench 2 are retained as permanent facilities for later pipe laying. This avoids the damage to the formed roadbed structure caused by the removal of temporary facilities and the excavation of the road surface to lay permanent pipes after completion, which would lead to quality problems such as road surface settlement and cracking in the later stage.
