Description

Technical Field

[0001] The present invention relates to the field related to municipal engineering, in particular to a municipal road, a casting template for its construction and a construction method thereof. Background Art

[0002] Municipal roads in municipal engineering refer to roads that are built, managed, and maintained by the city government or relevant municipal departments. They are mainly used to serve the city's internal system. They are also called municipal roads. Municipal roads usually allow free passage to the public. They not only serve local residents but also serve as transportation connections between cities. During the pouring construction of municipal roads, casting formwork is required to facilitate the pouring and shaping of municipal roads. The prior art publication number is CN110924257B, which is a municipal road, a casting template for its construction, and a construction method thereof. The key points of its technical solution are: it includes a soil layer, a road cushion layer, a waterproof layer, and a concrete layer arranged in sequence from bottom to top, and also includes sidewalks arranged on both sides; the concrete layer includes a permeable part and a reinforcement part distributed at staggered intervals, the width of the permeable part is 65mm-80mm, the permeable part is formed by pouring permeable concrete, the reinforcement part is formed by pouring ordinary concrete, the concrete layer also includes a spacer layer, the spacer layer is arranged between the permeable part and the reinforcement part, the spacer layer is formed by pouring permeable concrete; rainwater collection troughs are respectively provided on both sides of the waterproof layer, and the rainwater collection troughs are connected to the city sewer system. The effect of the present invention is that it solves the problem of road surface waterlogging and is applicable to most road surfaces; However, the above-mentioned technical solution still has the following deficiencies: the casting formwork is assembled and combined to form, and the connection between adjacent casting formworks is not firm enough. During the pouring process of the concrete layer of the municipal road, flow pressure is applied to the inner side of the casting formwork, which makes it easy for the concrete to flow out from the gap between adjacent casting formworks, reducing the stability of the casting and forming of the municipal road concrete layer. Moreover, the poured concrete consists of a reinforced part and a permeable part. The casting formwork cannot adjust the pouring volume of the two according to the drainage requirements of the municipal road, thereby reducing the drainage requirements of the municipal road after pouring.

[0016] See also Figure 1-7A municipal road of the present invention comprises a clay layer 1, a stone filling layer 2, and a waterproof layer 3, wherein the stone filling layer 2 is filled on the upper surface layer of the clay layer 1, and the waterproof layer 3 is provided on the upper layer of the stone filling layer 2; further comprising a reinforcement portion 5, a permeable portion 6, and a stone strip 7, wherein the reinforcement portion 5 and the permeable portion 6 are cast by a construction casting template to form a concrete layer, the reinforcement portion 5 and the permeable portion 6 are cast on the upper surface of the waterproof layer 3, the stone strip 7 is installed on both sides of the concrete layer formed by casting the reinforcement portion 5 and the permeable portion 6, and a permeable layer 71 is further installed at the lower end of the stone strip 7, wherein a drainage pipe 73 parallel to the permeable layer 71 is provided inside the permeable layer 71, and a prefabricated hole 72 vertically connected to the drainage pipe 73 is provided inside the permeable layer 71, and the prefabricated hole 72 is connected to the drainage pipe 73 through-connected; The casting formwork for construction includes: a combined casting formwork 4, which is vertically mounted on the upper surface of the waterproof layer 3, and a locking mechanism 42 is provided on the edge of the combined casting formwork 4. The locking mechanism 42 consists of a locking plate 421, a rotating frame 422, a linkage support plate 423 and a buckle tube 424. The locking plate 421 is fixed to the upper surface of the combined casting formwork 4, and the lower end of the rotating frame 422 is connected to the inner axis of the left end of the locking plate 421, the inner side of the rotating frame 422 is connected to the right end axis of the linkage support plate 423, and the left end of the linkage support plate 423 is welded with a buckle tube 424. A positioning rod 425 is also welded on the combined casting formwork 4, and adjacent combined casting formworks 4 are fixedly connected by buckling the positioning rod 425 with the buckle tube 424; It should be explained that a locking mechanism 42 and a positioning rod 425 are provided at the upper and lower ends between each two adjacent combined casting templates 4. The inner diameter of the fastening tube 424 matches the diameter of the positioning rod 425. The pressing of the locking mechanism 42 causes the fastening tube 424 to fasten the positioning rod 425, effectively improving the tight fit between the two adjacent combined casting templates 4, avoiding the flow pressure generated when the concrete layer is poured inside and causing the concrete to flow out from the gap between the adjacent combined casting templates 4, thereby improving the stability of the concrete layer casting and forming, and the fastening tube 424 and the positioning rod 425 can be quickly separated, which is convenient for later disassembly. A reinforcing rib 41 is welded to the middle part of the outer side of the combined casting formwork 4, and a supporting mechanism 43 is also provided on the outer side of the combined casting formwork 4. The supporting mechanism 43 is composed of a vertical rod 431, a rotating tube 432, a connecting rod 433, a positioning tube 434 and a fixing nail 435. The vertical rod 431 is welded to the outer side of the combined casting formwork 4, and the vertical rod 431 is passed through the interior of the rotating tube 432 with a clearance fit. The front end of the rotating tube 432 is welded to the rear end of the connecting rod 433, and a positioning tube 434 is welded to the front end of the connecting rod 433. A fixing nail 435 is provided inside the positioning tube 434. A placement hole 436 is also passed through the interior of the combined casting formwork 4, and the diameter of the placement hole 436 is larger than that of the fixing nail 435. It should be explained that there are two rotating tubes 432, and the rotating tube 432 at the upper end is also welded to the connecting rod 433 through an inclined support rod to form a triangular structure, which is relatively stable. The two rotating tubes 432 are rotated on the vertical rod 431 to rotate and adjust the positioning tube 434, thereby adjusting the position of the fixing nail 435 fixed on the upper surface of the waterproof layer 3, thereby improving the effect of the support mechanism 43 on supporting the combined casting formwork 4, and during the transportation of the combined casting formwork 4, the positioning tube 434 is rotated to the placement hole 436, and the lower end of the fixing nail 435 is extended into the placement hole 436, so that the supporting mechanism 43 can be stored as a whole on the outer surface of the combined casting formwork 4, thereby avoiding the support mechanism 43 from swinging randomly during transportation and causing inconvenience during transportation.

[0017] The inner side of the composite casting template 4 is also fixed with a partition 44, and the upper end of the composite casting template 4 is provided with a sliding groove 426. The front and rear ends of the partition 44 are slidably adjusted in the sliding grooves 426 of the front and rear composite casting templates 4, and the partition 44 and the composite casting template 4 are at a vertical angle. The front and rear ends of the composite casting template 4 are both provided with clamps 441 to clamp and fix the front and rear ends of the partition 44; the clamp 441 includes a positioning frame 4411, a knob 4412, a screw 4413, a sliding block 4414, and an extrusion rod 4415. The positioning frame 4411 is slidably installed inside the sliding groove 426, and the front and rear ends of the partition 44 are inserted into the corresponding front and rear positioning frames 4411. A knob 4412 is provided on the front surface of the positioning frame 4411, and the knob 4412 drives the screw 4413 to rotate synchronously. The screw 4413 is inserted into the sliding block 4414 with a clearance fit and is threadedly connected. The sliding block 4414 slides inside the positioning frame 4411. The sliding block 4414 is fixed to the extrusion rod 4415, and the extrusion rod 4415 squeezes and clamps the front and rear ends of the partition 44; It should be explained that the number of partitions 44 is selected according to the reinforcement part 5 and the permeable part 6 that need to be cast. In areas with less precipitation, the volume of the reinforcement part 5 is larger, while the volume of the permeable part 6 is smaller. The reinforcement part 5 is cast between two adjacent partitions 44 with a longer spacing, and the permeable part 6 is cast between two adjacent partitions 44 with a shorter spacing. In areas with more precipitation, the proportion of the permeable part 6 can be selected between 40%-50%, which is determined according to actual construction needs.

[0018] An inner partition 442 is installed on the inner side of the partition 44, and a hook plate 4421 is provided at one end of the inner partition 442. The hook plate 4421 is suspended on the upper end of the partition 44, and the hook plate 4421 is slidably installed in the guide groove 4401 provided inside the upper end of the partition 44; a partition plate 4422 is also installed on the partition 44, and a prefabricated drainage block 4423 is laid at the lower end of the partition plate 4422, and the prefabricated drainage block 4423 is located on the upper surface of the waterproof layer 3, a support rod 4231 is inserted and installed inside the drainage port of the upper end of the prefabricated drainage block 4423, and a support plate 4232 is provided at the upper end of the support rod 4231, and the support plate 4232 is located at the upper end of the prefabricated drainage block 4423, and a filter screen 4233 is further provided above the prefabricated drainage block 4423, and the filter screen 4233 is lower than the horizontal height of the reinforcement part 5 and the permeable part 6, and the prefabricated drainage block 4423 is connected with the prefabricated hole 72; It should be explained that a plurality of prefabricated drainage blocks 4423 are connected side by side to form a long strip structure. The modular prefabricated drainage blocks 4423 are used so that the number of prefabricated drainage blocks 4423 used can be selected according to the casting length of the permeable portion 6, ensuring that the laid prefabricated drainage blocks 4423 can be relatively matched with the casting length of the permeable portion 6, avoiding the prefabricated drainage blocks 4423 being too long or too short, and ensuring that the prefabricated drainage blocks 4423 can be installed on both sides of the permeable portion 6, thereby improving the drainage efficiency of the permeable portion 6; The number of support rods 4231 used is consistent with the number of prefabricated drainage blocks 4423 used. The support plate 4232 is supported by multiple support rods 4231 to ensure that when the gap is opened after the inner partition 442 is removed during casting, the cast permeable part 6 will not flow onto the prefabricated drainage block 4423, thereby avoiding the reserved drainage holes inside the prefabricated drainage block 4423 being blocked by the cast permeable part 6.

[0019] A municipal road construction method comprises the following specific steps: S1: After filling the upper surface of the clay layer 1 with a stone filling layer 2 and preparing a waterproof layer 3 on the upper surface of the stone filling layer 2, the combined casting formwork 4 is installed on the upper surface of the waterproof layer 3. The combined casting formwork 4 on both sides is placed symmetrically according to the width of the concrete layer to be poured for municipal road construction; S2: Multiple combined casting templates 4 on the same side are installed adjacent to each other. By pressing down the rotating frame 422 provided on the next combined casting template 4, the linked support plate 423 is pulled backward, and the linked support plate 423 moves downward and backward to drive the fastening tube 424 to fasten and fix the positioning rod 425 provided on the previous combined casting template 4, so that the two adjacent combined casting templates 4 are firmly installed. S3: Then, by moving the positioning tube 434, under the connection of the connecting rod 433 and the rotating tube 432, the positioning tube 434 is rotated around the vertical rod 431. After adjusting to a suitable angle, the fixing nail 435 is passed through the positioning tube 434 and nailed to the inside of the waterproof layer 3, providing support for the combined casting template 4 standing on the upper surface of the waterproof layer 3, preventing the combined casting template 4 from tilting during the casting process, and ensuring stability during the casting process; S4: After the combined casting formwork 4 on both sides is installed, according to the volume of the reinforcement part 5 and the permeable part 6 to be cast, the front and rear ends of the partitions 44 are inserted into the sliding grooves 426 and the positioning frames 4411 provided on the upper end of the combined casting formwork 4, and the spacing between the multiple partitions 44 is moved and adjusted to adjust the volume of the cast reinforcement part 5 and the permeable part 6. During the adjustment, the positioning frames 4411 move in the sliding grooves 426 following the movement and adjustment direction of the partitions 44. After adjusting to the determined position, the knob 4412 is turned to drive the screw 4413 to rotate, so that the sliding block 4414 is displaced, and the extrusion rod 4415 is brought out to squeeze and clamp the front and rear ends of the partitions 44, thereby improving the stability of the partitions 44, ensuring the separation of the cast reinforcement part 5 and the permeable part 6, and avoiding the mixing of the two during the casting process; S5: Install two inner partitions 442 at the front and rear ends of the partition 44, lay a prefabricated drainage block 4423 between the inner partition 442 and the combined casting formwork 4, and install two partition plates 4422 on both sides of the upper end of the prefabricated drainage block 4423. Do not cast the reinforcement part 5 and the permeable part 6 above the prefabricated drainage block 4423 to reserve drainage space, and cast the reinforcement part 5 between the two partition plates 4422 and the two partitions 44; S6: After pouring the reinforcement part 5 and the permeable part 6, the partition 44, the inner partition 442, and the partition plate 4422 are removed, and the support rod 4231 is tilted and placed inside the drainage hole at the upper end of the prefabricated drainage block 4423. The upper end of the support rod 4231 supports the support plate 4232. Then, the reinforcement part 5 is poured into the gap formed after the partition 44 is removed, and the permeable part 6 is poured into the gap formed after the inner partition 442 is removed. After the pouring is completed, the municipal road is formed, and the support rod 4231, the support plate 4232 and the combined pouring formwork 4 are removed; S7: After the concrete is poured, the upper permeable layer 71 is filled on both sides. The prefabricated holes 72 set inside the permeable layer 71 are aligned with the drainage holes inside the prefabricated drainage block 4423, and the drainage pipe 73 is installed inside the permeable layer 71. Then, the stone strips 7 are laid on the surface of the permeable layer 71, and the filter screen 4233 is installed on the upper end of the drainage space reserved above the prefabricated drainage block 4423. The filter screen 4233 can filter impurities on the road surface to prevent impurities from entering the prefabricated drainage block 4423 and causing blockage, thereby reducing the drainage effect in the later stage.
