DETAILED DESCRIPTION

[0017] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments.

[0018] The road integration construction method of the present invention comprises the following steps: Step 1: Construction of drainage side formwork ground-connected wall 1 After the roadbed is leveled, a trench is excavated below the curbstone 2 or the road side form 19 using a trenching machine, a formwork is set up in the trench, and concrete is poured to form a drainage side formwork ground-connected wall 1. The drainage side formwork ground-connected wall 1 formed by pouring is rectangular in shape as a whole, hollow inside, and the upper surface of the drainage side formwork ground-connected wall 1 is flush with the upper surface of the roadbed, that is, flush with the road ash soil layer, and the drainage side formwork ground-connected wall 1 is used as a road rainwater drainage ditch.

[0019] Step 2: Suspending the curb 2 The curbstone 2 used in the present invention is different from the traditional curbstone 2. The curbstone 2 of the present invention is symmetrically provided with through holes 3 on both sides of the bottom. The through holes 3 penetrate the curbstone 2 along the width direction of the curbstone 2. A lateral water inlet 4 is provided on the side of the curbstone 2 facing the road. A linear drainage groove 5 is provided inside the curbstone 2. The linear drainage groove 5 penetrates the curbstone 2 along the length direction of the curbstone 2. In this embodiment, the linear drainage groove 5 is a rectangular hollow space inside the curbstone 2. The linear drainage groove 5 is connected to the lateral water inlet 4. Rainwater enters the linear drainage groove 5 in the curbstone 2 through the lateral water inlet 4, and then is discharged to the inspection well 22 through the curbstone 2, and finally is discharged to the drainage side mold ground connecting wall 1 through the inspection well 22.

[0020] First, place several lifting devices evenly below the position where the curbstone 2 is to be placed. The lifting devices are placed on the upper surface of the drainage side mold ground-connected wall 1. The lifting devices are used to lift the curbstone 2 to the designed height. The lifting device in this embodiment uses a jack, and other lifting devices can also be used. Any existing device that can lift the curbstone 2 can be used. Unload the curbstone 2 onto the lifting device, and use the lifting device to lift the curbstone 2 to the designed height, so that the curbstone 2 is suspended in the air. At the same time, the horizontal and vertical flatness of adjacent curbstones 2 are adjusted by the leveler 6, that is, the upper surfaces of adjacent curbstones 2 are on the same horizontal plane and the sides are on the same vertical plane. The leveler 6 can be a commonly used stone leveler. The leveler 6 in this embodiment uses a suction cup leveler.

[0021] Step 3: Fix the curb 2 A transverse long screw rod 7 is passed through the through hole 3 of the curb 2, and three-way nuts A8 are threadedly connected at both ends of the transverse long screw rod 7. The horizontal distance between the two three-way nuts A8 is equal to the horizontal distance between the inner backrest and the outer backrest of the curb 2. A hole is drilled downward on the drainage side mold ground connecting wall 1 just below the three-way nut A8, and then the vertical long screw rod 9 is inserted into the drilled hole. A three-way nut B10 is provided in the middle of the vertical long screw rod 9, and the lower part of the vertical long screw rod 9 is threadedly connected to the adjusting nut 11, and the adjusting nut 11 can move up and down on the vertical long screw rod 9. The upper end of the vertical long screw rod 9 is screwed upward into the three-way nut A8, and then the adjusting nut 11 is tightened downward to fix the vertical long screw rod 9. A horizontal transverse push rod 12 is threaded outwardly on the three-way nut B10. The transverse push rod 12 is used to support the inner side of the road side mold template 15, and the direction of the transverse push rod 12 is consistent with the width direction of the curb 2. The curbstone 2 has been supported in the air by the vertical long screw rod 9, and the lifting device under the curbstone 2 is removed at this time.

[0022] In order to make the curb 2 more stable, two nuts 14 are threadedly connected on the transverse long screw rod 7, the two nuts 14 are located between the two three-way nuts A8, and the two nuts 14 are respectively located on both sides of the curb 2. The curb 2 is further stabilized by tightening the nuts 14 to the curb 2. More preferably, a gasket is provided between the nut 14 and the side of the curb 2, and the gasket is a rubber gasket 13, which can prevent the surface of the curb 2 from being damaged and further increase the friction.

[0023] In this embodiment, a top plate 16 is preferably provided at the outer end of the transverse top rod 12. In this embodiment, the top plate 16 is a circular plate, and the top plate 16 increases the area where the force on the road side mold template 15 acts.

[0024] Step 4: Install pipeline 18 A pipeline limiting rod 17 is installed between the vertical long screws 9 on both sides, and several pipeline limiting rods 17 are connected from top to bottom. A pipeline 18 is placed on the pipeline limiting rod 17, and the pipeline 18 is further fixed to the pipeline limiting rod 17 by a pipe clamp. The pipe clamp is not drawn in the attached figure. The pipe clamp is a fixing component commonly used when laying the pipeline 18, and it will not be repeated here. The vertical distance between the upper and lower adjacent pipeline limiting rods 17 is equal to the outer diameter of the pipeline 18. The pipeline 18 is limited by the pipeline limiting rod 17 to prevent the pipeline 18 from drifting up and down during the later concrete pouring. The pipeline limiting rod 17 can be made of various types of components. For example, the pipeline limiting rod 17 can be a steel bar, and the two ends of the steel bar are directly welded to the vertical long screws 9 on both sides. The present invention does not impose special restrictions on this. In this embodiment, the pipeline limiting rod 17 is preferably a basket bolt. By adjusting the length of the basket bolt, the tensioning force on the vertical long screws 9 on both sides can be conveniently adjusted.

[0025] Step 5: Install the road side formwork 15 After the pre-buried pipeline 18 is installed, the road side formwork 15 is supported. The road side formwork 15 is placed according to the designed width of the road side formwork 19, and the road side formwork 15 is supported. The outer side of the road side formwork 15 is supported and fixed according to the conventional method, and the inner side of the road side formwork 15 is tightened by the transverse push rod 12. The transverse push rod 12 is rotated to make it tightly press against the inner side of the road side formwork 15.

[0026] Step 6: Casting road side formwork 19 After the road side formwork 15 is installed, concrete is poured to the designed elevation to form the road side formwork 19, which is formed integrally with the pipeline 18. After the road side formwork 19 reaches the required strength, the road side formwork 15 is removed.

[0027] Step 7: Install the curb back template The curbstone backrest template is installed on the road side form 19. The curbstone backrest template is divided into an outer backrest template 20 and an inner backrest template 21. Here, the outer side refers to the side away from the road, and the inner side refers to the side close to the road. The curbstone backrest template is placed on the road side form 19, and the outer side is supported and fixed according to the conventional method, and the inner side is tightened by the three-way nut A8. The distance between the lower surface of the curbstone 2 and the upper surface of the road side form 19 is the thickness of the curbstone cushion layer.

[0028] Step 8: Cast the curb back After the curbstone backrest formwork is set up, concrete is poured to form the curbstone cushion layer, the curbstone outer backrest and the curbstone inner backrest in one piece.

[0029] Step 9: Curbstone 2, inspection well 22, drainage side mold ground wall 1 connected An inspection well 22 is constructed at intervals, and generally an inspection well 22 is set every 50-100m. The upper side of the inspection well 22 of the present invention is provided with an outwardly extending water inlet 23. The curbstone 2 corresponding to the inspection well 22 is no longer constructed as a curbstone outer backrest, but an opening 24 matching the water inlet 23 of the inspection well 22 is opened on the outer side of the curbstone 2. The opening 24 is connected to the linear drainage groove 5. The water inlet 23 of the inspection well 22 can be inserted into the opening 24 of the curbstone 2 to connect the inspection well 22 with the linear drainage groove 5. The lower part of the inspection well 22 is provided with an outwardly extending water outlet 25, and the water outlet 25 is connected to the drainage side mold ground connecting wall 1. The rainwater in the curbstone 2 is discharged into the drainage side mold ground connecting wall 1 through the inspection well 22, eliminating the construction of traditional road drainage pipes and rainwater grates, and ensuring the integrity of the road surface.

[0030] Preferably, a sedimentation tank 26 is provided at the bottom of the inspection well 22, and the sedimentation tank 26 is located below the water outlet 25. A filter screen frame 27 is provided in the inspection well 22. The shape of the filter screen frame 27 is consistent with the shape of the inspection well 22, and is surrounded by frames. The filter screen is connected between the frames. The filter screen is used to filter out large solids such as leaves to avoid blockage at the connection between the water outlet 25 and the drainage side mold ground connecting wall 1. In this embodiment, the filter screen frame 27 is preferably a metal frame, and stainless steel mesh is provided between the metal frames. The filter screen frame 27 is placed above the sedimentation tank 26. When it needs to be cleaned, the manhole cover 28 of the inspection well 22 above is opened, and the filter screen frame 27 can be lifted out of the inspection well 22.

[0031] The present invention integrates the construction and installation of the drainage side formwork ground-connected wall 1, the road side formwork 19, the curb 2, the curb backrest and the curb cushion layer, without the need to cut grooves to damage other structures, avoiding the back-excavation process and saving the use of backfill materials. It can realize integrated and standardized rapid construction, greatly improving construction efficiency and quality.

[0032] The road side formwork 19 and curbstone 2 constructed in advance of the present invention provide construction boundaries and control points for paving height for the later paving of the road water-stabilizing layer and asphalt surface layer. Later, lines can be drawn on the road side formwork 19, curbstone backrest, and curbstone 2 to control the paving height of each layer of the road without the need to set up other elevation control devices.

[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them. Those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some of the technical features therein with equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
