Description

A fine aggregate pervious concrete layer is arranged below the ceramic pervious particle surface layer, and a coarse aggregate pervious concrete layer is arranged below the fine aggregate pervious concrete layer. A construction method of a colored ceramic particle pervious pavement structure with rail edging includes the following steps: Step S1, within the greenway range, after surface cleaning, the soil base is shaped and compacted. This method uses fired through-colored ceramic particle materials as the surface layer, effectively avoiding the discoloration of the greenway caused by outdoor conditions. At the same time, the material fineness gradually becomes coarser from top to bottom, which can prevent the problem of the reduction of the pervious rate caused by the blockage of structural holes by sediment particles. A drainage pipe is arranged at the base to effectively drain the pervious water in the greenway. However, on-site, the method of directly covering with thermal insulation black heart cotton manually is mostly adopted, which not only incurs costs, but also easily causes the problems of particle detachment, cracking, and hollowing of the pervious concrete.

[0041] In order to make the objectives, technical solutions and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0042] In order to solve the technical problem in the prior art that when constructing permeable concrete, the maintenance method of directly covering heat-insulating black heart cotton manually is adopted, resulting in problems such as particle detachment, cracking and hollowing of the permeable concrete, the present utility model provides a concrete film covering device, which can realize that when the traveling wheel 21 travels along the guide of the railway track, the plastic film roller can rotate relative to the clamping member 31, and the plastic film is laid on the surface of the permeable concrete.

[0043] It should be noted that the concrete film covering device described in the present utility model is used in but not limited to the technical field of construction equipment. For the convenience of description, in the present utility model, only the case where the concrete film covering device is applied to the technical field of construction equipment is taken as an example for description, and the principle of the concrete film covering device applied to other types of equipment is substantially the same as that applied to the technical field of construction equipment, which will not be elaborated here one by one.

[0044] See also Figures 1 to 3 , Figure 1 This is a structural schematic diagram of a concrete covering device in an embodiment of the present invention. The concrete covering device is used to connect a plastic film roller, including: a bracket 1, a walking assembly 2 and a clamping assembly 3. The walking assembly 2 includes two walking wheels 21, which are arranged on both sides of the bracket 1 and are respectively rotatably connected to the bracket 1, and the walking wheels 21 are used to cooperate with the rails and roll along the guide of the rails. The clamping assembly 3 includes two clamping members 31, which are arranged opposite to each other and are respectively slidably connected to both sides of the bracket 1, and the two clamping members 31 can slide towards or away from each other to clamp the two ends of the plastic film roller, and the plastic film roller can rotate relative to the two clamping members 31 and the bracket 1 to lay the plastic film.

[0045] In this device, a walking component 2 and a clamping component 3 are provided on the bracket 1, wherein the walking component 2 includes two walking wheels 21 respectively provided on both sides of the bracket 1, which are used to cooperate with the rails and walk along the guide of the rails, and the clamping component 3 includes two clamping members 31 relatively provided on both sides of the bracket 1, and the two clamping members 31 can slide towards or away from each other, and are used to clamp the two ends of the plastic film roller, and the plastic film roller can rotate relative to the two clamping members 31 for laying the plastic film.

[0046] Compared with the existing technology, by setting two walking wheels 21 that can cooperate with the rails for running, and two clamping parts 31 for clamping the two ends of the plastic film roller, when the driving wheel 21 is guided along the rails, the plastic film roller can rotate relative to the clamping parts 31 and lay the plastic film on the surface of the permeable concrete. This can solve the technical problem in the existing technology that the permeable concrete is prone to threshing, cracking and hollowing due to the maintenance method of manually directly covering the thermal insulation black cotton during the construction of the permeable concrete.

[0047] Furthermore, the plastic film is usually wrapped around a plastic film roller. By fixing one end of the plastic film and driving the plastic film roller to rotate at the same time, the automatic laying and winding of the plastic film can be achieved. The plastic film and plastic film roller here are common and easy-to-purchase equipment on the market. This is a conventional setting known to technicians in this field and will not be elaborated on.

[0048] Specifically, the walking wheel 21 in this application is a stepped roller, which can cooperate with the rail with an "I"-shaped cross-section and run along the guide of the rail. The walking wheel 21 here belongs to a conventional setting known to technical personnel in this field and will not be described in detail.

[0049] In this embodiment, Figure 2As shown in the figure, the bracket 1 includes a first main beam 11, a second main beam 12 and at least one connecting beam 13.

The connecting beam 13 is arranged between the first main beam 11 and the second main beam 12, and both ends of the connecting beam 13 are respectively connected to the first main beam 11 and the second main beam 12. Two clamping members 31 are respectively slidably connected to both ends of the first main beam 11, and two traveling wheels 21 are respectively rotatably connected to both ends of the second main beam 12.

[0050] The bracket 1 is composed of a first main beam 11, a second main beam 12 and at least one connecting beam 13 to form a weight-reducing structure, which can be pushed by a single person, facilitating operation and use.

[0051] Among them, the first main beam 11 plays a role in supporting and connecting the two clamping members 31, and the second main beam 12 plays a role in supporting and connecting the two traveling wheels 21.

[0052] In one embodiment, please refer to Figures 1 to 3 , in the bracket 1, the number of connecting beams 13 is two. The two connecting beams 13 are parallel to each other and arranged at intervals between the first main beam 11 and the second main beam 12, and are respectively connected to the first main beam 11 and the second main beam 12.

[0053] The two connecting beams 13 are parallel to each other and arranged at intervals, which can increase the connection strength between the first main beam 11 and the second main beam 12 and ensure the stability of the device.

[0054] In this embodiment, the clamping assembly 3 further includes two first sliding rods 32 and a first clamping portion 33.

[0055] Among them, the clamping member 31 includes a clamping cone 311 and a connecting plate 312. The two clamping cones 311 are arranged oppositely, and the cross-sectional areas of the two clamping cones 311 gradually decrease in the direction of approaching each other. The two clamping cones 311 can be respectively inserted into the ends of both ends of the plastic film roller, and the ends of the plastic film roller can rotate relative to the clamping cones 311. The connecting plate 312 is arranged perpendicular to the first sliding rod 32, and one end of the connecting plate 312 is connected to the clamping cone 311 and the other end is connected to one end of the first sliding rod 32.

[0056] The clamping member 31 is composed of two oppositely arranged clamping cones 311, and the two clamping cones 311 are respectively connected to the first sliding rod 32 through the connecting plate 312. After the two clamping cones 311 approach each other, they can not only clamp the ends of both ends of the plastic film roller, but also enable the plastic film roller to rotate relative to the two clamping cones 311.

[0057] Specifically, in this device, the clamping cone 311 is in the shape of a frustum of a cone, and the small-diameter sections of the two clamping cones 311 can be inserted into the ends of both ends of the plastic film roller.

[0058] In one embodiment, please refer toFigures 1 to 3 At both ends of the first main beam 11, first sliding grooves are respectively formed. One end of the first sliding rod 32 is connected to the clamping member 31, and the other end is slidably inserted into the first sliding groove. The first clamping portion 33 is connected to the first main beam 11 and can be clamped with the first sliding rod 32 to limit the relative sliding of the first sliding rod 32 with respect to the first main beam 11.

[0059] Through the clamping of the first clamping portion 33 and the first sliding rod 32, the relative sliding of the first sliding rod 32 and the clamping cone 311 with respect to the first main beam 11 can be limited, so as to adjust the distance between the two clamping cones 311, and thus the width dimension of the plastic film can be selected according to different usage scenarios.

[0060] As one implementation, as Figures 1 to 3 shown, at both ends of the first main beam 11, first sliding grooves are respectively formed. The clamping assembly 3 further includes two first sliding rods 32 and a first clamping portion 33. One end of the first sliding rod 32 is connected to the clamping member 31, and the other end is slidably inserted into the first sliding groove. The first clamping portion 33 is connected to the first main beam 11 and can be clamped with the first sliding rod 32 to limit the relative sliding of the first sliding rod 32 with respect to the first main beam 11.

[0061] The first clamping portion 33 is connected to the first main beam 11 by means of threaded connection and limits the sliding of the first sliding rod 32 by means of abutment, which is not only simple in structure but also convenient to operate.

[0062] Furthermore, the first clamping portion 33 here is a common and easily purchasable wing bolt, screw or bolt in the market, which belongs to the conventional settings well-known to those skilled in the art and will not be elaborated too much here.

[0063] In this embodiment, the traveling assembly 2 further includes a sliding member 22. One end of the sliding member 22 is rotatably connected to the traveling wheel 21, and the other end can slide relative to the second main beam 12.

[0064] The traveling wheel 21 is connected to the second main beam 12 through the sliding member 22, so that the distance between the two traveling wheels 21 can also be adjusted according to different usage situations, improving the adaptability of the device.

[0065] In one of the embodiments, please refer to Figures 1 to 3 , at both ends of the second main beam 12, second sliding grooves are respectively formed. The sliding member 22 includes a second sliding rod 221 and a second clamping portion 222. One end of the second sliding rod 221 is rotatably connected to the traveling wheel 21, and the other end is slidably inserted into the second sliding groove. The second clamping portion 222 is connected to the second main beam 12 and can be clamped with the second sliding rod 221 to limit the relative sliding of the second sliding rod 221 and the traveling wheel 21 with respect to the second main beam 12.

[0066] By engaging the second engaging portion 222 with the second sliding rod 221, the sliding of the second sliding rod 221 relative to the second main beam 12 can be restricted.

[0067] As one implementation, for example, Figure 2 As shown, the second main beam 12 is further provided with two second threaded holes, which are arranged in one-to-one correspondence with the second sliding grooves and communicate with the second sliding grooves. The second engaging portion 222 has a large-diameter section and a threaded section. The threaded section of the second engaging portion 222 is threadedly connected to the second threaded hole and abuts against the second sliding rod 221.

[0068] Specifically, in this application, the detachable connection between the second engaging portion 222 and the second main beam 12 is realized by means of threaded connection, and by means of abutting, the function of restricting sliding can be achieved.

[0069] In one embodiment, please refer to Figures 1 to 3 , the device further includes two handrails 4. The two handrails 4 are parallel to each other and arranged at intervals, and one end of the handrail 4 is connected to the first main beam 11, and the other end extends in a direction away from the first main beam 11.

[0070] With the two handrails 4 arranged at intervals, the user can push the device to walk along the guide of the railway track alone, achieving the purpose of automatic film covering. It is not only simple in structure but also convenient to operate.

[0071] To better understand the present utility model, the technical solutions of the present utility model will be described in detail below in conjunction with Figures 1 to 3 :

The clamping assembly 3 includes two clamping members 31 oppositely arranged on both sides of the bracket 1. The two clamping members 31 can slide closer to or away from each other, and are used to clamp both ends of the plastic film roller. The plastic film roller can rotate relative to the two clamping members 31 for laying the plastic film. Compared with the prior art, by providing two traveling wheels 21 that can cooperate with the railway track to travel, and two clamping members 31 for clamping both ends of the plastic film roller, when driving the traveling wheels 21 to travel along the guide of the railway track, the plastic film roller can rotate relative to the clamping members 31, and the plastic film can be laid on the surface of the permeable concrete.

[0073] In use, the user first loosens the second clamping part 222, drives the second sliding rod 221 to slide relative to the second main beam 12, and adjusts the distance between the two traveling wheels 21 according to the distance between the two rails. Then, the user loosens the first clamping part 33, drives the first sliding rod 32 to slide relative to the first main beam 11, and adjusts the distance between the two clamping cones 311 according to the width of the pervious concrete to be constructed. Then, the plastic film roller is placed between the two clamping cones 311, and the two clamping cones 311 are respectively inserted into the ends of both ends of the plastic film roller. Finally, the user holds the handrail 4 and pushes the bracket 1 along the guide of the rail. While the traveling wheels 21 travel along the guide of the rail, the plastic film roller rotates relative to the clamping cones 311, and automatic film covering is completed.

[0074] Further, in this application, both the first main beam 11 and the second main beam 12 are hollow steel pipes with a diameter of 30 mm and a length of 1000 mm; the first sliding rod 32 is arc-shaped, and it is a hollow steel pipe with a diameter of 25 mm, a transverse length of 500 mm, and a vertical length of 100 mm; the second sliding rod 221 is a hollow steel pipe with a diameter of 25 mm and a length of 500 mm; the traveling wheels 21 are composed of a tread and a wheel rim.
