Description

Technical Field

[0001] The present invention relates to the technical field of sponge city permeable ground pouring, and particularly relates to a sponge city permeable ground pouring device and a pouring method thereof. Background Art

[0002] A sponge city permeable ground refers to a city ground that uses materials with good water permeability and adopts a special construction method to make the ground have a certain water permeability, so that rainwater and surface runoff can quickly penetrate into the ground, achieving effects such as reducing urban rainwater accumulation and waterlogging and improving the urban ecological environment; generally, permeable concrete is used for the sponge city permeable ground. Permeable concrete has good water permeability and can reduce the impact of rainfall runoff on the urban drainage system under rainfall conditions.

[0003] Permeable concrete is usually a mixture of mineral self-curing cement and ordinary concrete admixtures. During its preparation process, large particle aggregates and a smaller amount of cement are required. Its cement dosage is reduced by 20% to 50% compared with traditional concrete, which can increase the porosity of the concrete, thereby enhancing the water permeability and air permeability of the concrete. The water permeability of permeable concrete can not only quickly penetrate surface water into the soil after rainfall, but also provide sufficient water for the growth of plants.

[0004] Currently, before pouring permeable concrete, the roadbed must be wetted with water first. Otherwise, the rapid loss of water in the permeable floor will weaken the bonding strength between the aggregates. During the pouring process, strong vibration or ramming is also required. The flat vibrator is used to gently vibrate and level the permeable concrete mixture, and high-frequency vibrators cannot be used, otherwise the concrete will be too dense, reducing the porosity and affecting the water permeability effect. In the above construction process, a variety of machines and tools are required to meet the construction requirements, and the equipment used is complicated, the construction process is numerous, and it is time-consuming and laborious.

The rectangular connecting plate 811 drives the scraping plate 812 through the fourth compression spring 813 to make reciprocating scraping action on the roadbed. The road pressing plate 101 intermittently makes light vibration and paving on the concrete, avoiding the problem of excessive densification reducing the porosity and affecting the water permeability effect. At the same time, cooperating with the scraping plate 812 can avoid the concrete being extruded out of the road surface during the feeding process.

[0046] Refer to Figure 1 、 Figure 2 and Figure 4 , the paving unit 9 includes a transmission shaft 91 rotatably connected through the front and rear side plates 4. Symmetrically arranged on the outer ends of the transmission shaft 91 are support arms 92. The ends of the front and rear support arms 92 far from the transmission shaft 91 are jointly rotatably connected with a rotating shaft 93. A roller 94 is sleeved between the rotating shaft 93 and the support arms 92. Side mudguards 95 are rotatably connected to both sides of the rotating shaft 93 and the roller 94. The upper ends of the left and right side mudguards 95 are jointly fixedly connected with an arc-shaped mudguard 96. An L-shaped connecting rod 97 is arranged at the end of the side mudguard 95 close to the support arm 92 and fixedly connected to the support arm 92. A cover plate 98 is arranged at the left end of the arc-shaped mudguard 96. A scraping plate 99 close to the roller 94 is arranged under the cover plate 98. A detachable baffle 102 is arranged at the left end of the cover plate 98.

[0047] Refer to Figure 1 、 Figure 2 and Figure 4During specific operation, the transmission shaft 91 is driven by an external motor (not shown in the figure) to control the support arm 92 to be lowered or retracted. The roller 94 can roll the road surface when it contacts the roadbed surface where concrete is poured. The concrete scraped by the scraper 99 is collected in the collection tank formed by the cover plate 98 and the scraper 99. After a period of time, the detachable baffle 102 is opened to discharge the scraped concrete in a centralized manner to prevent the uneven surface of the roller 94 from affecting the rolling flatness of the road surface.

[0048] The present invention also provides a method for pouring permeable ground in a sponge city, which specifically includes the following steps: S1: first, the vehicle body 1 is advanced at a uniform speed, and then an appropriate amount of concrete is added from the feeding port 7 at the upper end of the top plate 3, and at the same time, the inverted concave water tank 51 is filled with clean water that meets the construction requirements, and then the No. 2 water spray pipe 57 is stretched to the required width, and the water pump 52 is turned on to transport the clean water to the No. 1 water spray pipe 54 to evenly wet the roadbed surface.

[0049] S2: Start the micro motor 117, the micro motor 117 drives two ball screws 115 with different rotation directions to rotate simultaneously through the coupling 116, and the screw sleeves 119 on both sides drive the No. 1 slider 111 to slide back and forth above the slide rail 121 at the same time, and the No. 1 slider 111 drives the rectangular slide bar 65 to slide back and forth inside the No. 1 rectangular slide groove 63 through the No. 1 connecting rod 64, and the rectangular slide bar 65 drives the detachable cylindrical material lever 67 to do reciprocating motion through the rectangular connecting block 66, and the concrete is moved back and forth so that it falls to the foundation evenly through the discharge holes 79 on the front and rear sides. At the same time, the No. 1 connecting rod 64 drives the No. 2 connecting rod 71 to slide back and forth inside the No. 1 rectangular groove 68, and the No. 2 connecting rod 71 drives the inverted concave slider 72 to slide back and forth inside the No. 2 rectangular slide groove 70 on the left side. The concave sliding blocks 72 on the left and right sides simultaneously drive the material-dispensing plate 73 to reciprocate. During the reciprocating motion of the material-dispensing plate 73, the No. 1 semicircular top block 77 is intermittently in contact with the No. 2 semicircular top block 80. The rectangular sliding plate 76 lifts the No. 1 semicircular top block 77 through the No. 1 compression spring 75 to make an up and down reciprocating motion. The No. 1 semicircular top block 77 drives the rectangular scraper 78 to make an up and down reciprocating motion. When the multiple material-dispensing plates 73 on both sides reciprocate, they can flatten the uneven concrete dropped from the discharge hole 79; the rectangular scraper 78 makes an up and down reciprocating motion, which can scrape off the concrete attached to the two sides of the material-dispensing plate 73. In addition, by cooperating with the width-limiting plate 601 and the detachable material-dispensing rod 67, the material-dropping width can be freely controlled for roadbeds of different widths.

[0050] S3: Start the motor 81. The motor 81 controls the rotation of the cam 82 to drive the roller 83 to move up and down reciprocally. The roller 83 drives the first support column 85 to move up and down reciprocally through the concave support frame 84. The first support column 85 moves up and down reciprocally inside the cylindrical sliding sleeve 86, and drives the connecting disc 90 to move up and down reciprocally through the second support column 89. The connecting disc 90 drives the road pressing plate 101 to move up and down reciprocally. At the same time, the concave support frame 84 drives the first rotating cylinder 802 to move up and down reciprocally through the second support plate 801. The first rotating cylinder 802 drives the third connecting rod 807 to move up and down reciprocally. The third connecting rod 807 drives the third support plate 805 inside the side plate 4 to move back and forth reciprocally through the second rotating cylinder 806 inside the side plate 4. The third support plate 805 inside the side plate 4 drives the second rectangular slider 804 to slide back and forth inside the fifth rectangular sliding groove 803. The second rectangular slider 804 drives the second rotating cylinder 806 outside the side plate 4 to slide along through the third support plate 805 outside the side plate 4. The second rotating cylinder 806 outside the side plate 4 drives the fourth connecting rod 810 to swing reciprocally through the restriction of the third rotating cylinder 809. The fourth connecting rod 810 drives the rectangular connecting plate 811 to swing reciprocally through the third rotating cylinder 809. The rectangular connecting plate 811 drives the scraping plate 812 to perform a reciprocating scraping action on the roadbed through the fourth compression spring 813. The road pressing plate 101 intermittently vibrates and levels the concrete gently. The reciprocating swing of the scraping plate 812 can prevent the concrete from being extruded out of the road surface during the feeding process.

[0051] S4: Drive the support arm 92 to lower through the external motor driving the transmission shaft 91. When the roller 94 contacts the surface of the roadbed where the concrete is poured, it can roll the road surface. The concrete scraped by the mud scraping plate 99 is concentrated and collected inside the collection groove formed by the cover plate 98 and the mud scraping plate 99, and can be discharged centrally through the detachable baffle 102 to avoid the unevenness of the surface of the roller 94 affecting the rolling flatness of the road surface.
