Description

Technical Field

[0001] This application belongs to the field of construction site enclosure technology, specifically a construction site enclosure for road construction. Background Technology

[0002] Construction site fencing is a common method of isolation used at construction sites. Its purpose is to separate the construction area from the outside world, ensure construction safety, and restrict unrelated personnel or vehicles from entering the construction area.

[0003] The construction barriers are temporarily fixed to the ground and need to maintain their structural stability during construction. Road construction can take anywhere from a few days to several months. When the construction period is long, the barriers are usually fixed using expansion bolts or cast-in-place concrete. While this method is sturdy and reliable, it is inconvenient to dismantle, may damage the road surface, and requires additional time and material costs for repairs.

[0004] To install construction barriers without damaging the road surface, existing technologies include water-filled barriers that can be installed without drilling. These barriers have a hollow interior with a water storage cavity. When water is poured into the cavity, the barriers become heavier, making them less prone to movement or wobbling. Even without a connection structure between them and the road surface, they provide stable support. The advantages of these water-filled barriers are easy installation and no damage to the road surface. The disadvantage is that adjacent barriers are not connected, which can lead to relative movement and gaps over time. Utility Model Content

[0023] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains.

[0024] Please refer to the following: Figures 1 to 9 The following describes the road construction fencing provided in the embodiments of this application.

[0025] This application provides a road construction fence, including multiple fence units 10, tension ropes 20, and connecting units 30. The multiple fence units 10 are sequentially connected along a straight line, and each fence unit 10 has a through-hole 111 along the connection direction. The tension ropes 20 are sequentially inserted through the through-holes 111 of the multiple fence units 10, and the tension ropes 20 are configured with prestress extending outwards along their own length. Connecting units 30 are provided at both ends of the tension ropes 20, and the connecting units 30 abut against the fence units 10 located at their respective ends.

[0026] Compared with the prior art, the beneficial effects of the road construction fencing provided in this application embodiment are: The road construction fencing provided in this application includes multiple fencing units 10, tension ropes 20, and connecting units 30. The fencing units 10 are connected end to end in a row, which can separate the construction area from the outside. The fencing units 10 have clearance holes 111 that are connected to each other in a straight line. The tension ropes 20 are passed through the clearance holes 111. The connecting units 30 are respectively connected to both ends of the tension ropes 20. The tension ropes 20 are configured with tensile prestress. Under the combined action of the tensile prestress of the tension ropes 20 and the connecting units 30, the multiple fencing units 10 can be tightly attached to each other and are not easy to move relative to each other during use, thereby improving the connection stability between the multiple fencing units 10. Even if they are not fixed to the ground by drilling holes, the multiple fencing units 10 are not easy to move relative to each other.

[0027] The fencing unit 10 is either a water-filled barrier or a concrete barrier. Its heavy weight makes it difficult to move or sway, providing stable support even without a connection structure to the road surface. The height of the fencing unit 10 is typically greater than 2.5m. There are no specific restrictions on the thickness and length of the fencing unit 10; users can set it according to their actual needs.

[0028] Multiple fencing units 10 are arranged sequentially, end to end. A plug-in structure can be provided between two adjacent fencing units 10 to improve the reliability of the connection and avoid large offsets. For example, one side of the fencing unit 10 has a concave hole and the other side has a protrusion, and the concave hole of the previous fencing unit 10 and the protrusion of the next fencing unit 10 are adapted to each other.

[0029] The tension rope 20 is used to provide prestress that tightly binds multiple enclosure units 10 together. The tension rope 20 should be a rope capable of elastic deformation, and it can be a rubber rope, steel wire rope, or a rope woven from composite materials. Under the action of prestress, the tension rope 20 undergoes elastic deformation and elongates. After the enclosure units 10 are removed, the prestress is eliminated, and the tension rope 20 returns to its original state.

[0030] To prevent the tension rope 20 from returning to its original shape under the action of prestress, a connecting unit 30 is installed at each end of the tension rope 20. The connecting unit 30 is detachably connected to the tension rope 20 and abuts against the enclosure unit 10, so that the prestress of the tension rope 20 can be applied to the enclosure unit 10 through the connecting unit 30.

[0031] There is no limit to the specific number of enclosure units 10. When there are many enclosure units 10 and the enclosure is long, three or four enclosure units 10 can be connected by a tension rope 20. One, two or more clearance holes 111 can be provided on the enclosure unit 10. At least one tension rope 20 is threaded through each clearance hole 111, and each tension rope 20 is connected to a connecting unit 30 at both ends.

[0032] There are no restrictions on the specific structural form of the connecting unit 30. The connecting unit 30 can be directly selected from existing clamping parts, clips, etc. on the market that are suitable for rope connection.

[0033] During installation, multiple enclosure units 10 are first placed side by side in the installation position, with adjacent enclosure units 10 fitting tightly against each other. Tensioning ropes 20 are then threaded through the clearance holes 111 of the multiple enclosure units 10, so that both ends of the tensioning ropes 20 extend out of the clearance holes 111.

[0034] Then, the connecting unit 30 is installed at both ends of the tension rope 20, at which point the connecting unit 30 is in a loose state. Using mechanical equipment such as winches, tension jacks, and hydraulic cylinders, the working ends of these devices are connected to both ends of the tension rope 20. The mechanical equipment simultaneously applies tension to both ends of the tension rope 20. The specific value of the tension force should be less than the ultimate tensile stress that the tension rope 20 can withstand to prevent it from breaking. The structure and usage of the tension jacks and other mechanical equipment are existing technologies and will not be described in detail here.

[0035] Finally, after the tension reaches the preset value, the connecting unit 30 is fixed so that the connecting unit 30 is fixedly connected to the tension rope 20. The connecting unit 30 abuts against the enclosure unit 10 located at the edge. The tension prestress is applied to the enclosure unit 10 through the connecting unit 30, so that the multiple enclosure units 10 fit tightly together and do not move relative to each other.

[0036] Please see Figure 1 When the enclosure unit 10 is a water-filled barrier, the enclosure unit 10 is integrally molded by injection molding. The enclosure unit 10 has a hollow interior forming a water storage cavity. The enclosure unit 10 has a water injection hole at the top and a water discharge hole at the bottom. The water injection hole and the water discharge hole are respectively connected to the water storage cavity. The water injection hole and the water discharge hole are respectively provided with detachable sealing components, such as screw plugs or rubber plugs.

[0037] To prevent deformation after prolonged use, a metal bushing can be installed inside the clearance hole 111 of the enclosure unit 10. The metal bushing can improve the compressive strength of the enclosure unit 10 under prestress.

[0038] Please see Figures 2 to 9 When the enclosure unit 10 is a mechanically assembled structure, the enclosure unit 10 includes a precast concrete base 11, columns 12, and partitions 13. The columns 12 are connected to the concrete base by bolts, and the partitions 13 are connected to the columns 12 by bolts, snap-fit, or other means.

[0039] The precast concrete base 11 extends along the connection direction and has a clearance hole 111, which can be formed by a steel pipe or corrugated pipe pre-embedded in the precast concrete base 11. The cross-sectional shape of the precast concrete base 11 can be square or trapezoidal. The precast concrete base 11 is placed directly on the ground during installation.

[0040] Considering that the precast concrete base 11 is heavy and requires a crane for lifting during installation, lifting rings or other structures can be installed on the precast concrete base 11 to facilitate lifting.

[0041] The posts 12 are installed on the upper surface of the precast concrete base 11. The concrete height is approximately 0.5m, and the height of the posts 12 is typically 2-3m. The overall height of the final fencing unit 10 is 2.5-3.5m. Warning lights, lighting fixtures, and other lighting equipment can be installed on the top of the posts 12. Each precast concrete base 11 has at least one post 12. When there are multiple posts 12, they are spaced apart along the length of the precast concrete base 11. Partitions 13 are installed between adjacent posts 12. The partitions 13 can be made of materials such as steel plates or plastic plates, and can be a single plate or a multi-layer composite plate. The exterior of the partitions 13 can be decorated with artificial turf, posters, etc., to enhance the aesthetics of the fencing.

[0042] Please see Figure 5In some possible embodiments, the column 12 has a receiving groove along the height direction, the receiving groove extends through the top of the column 12, the edge of the partition 13 is accommodated in the receiving groove, the partition 13 is inserted into the receiving groove from the top downwards, the receiving groove can restrict the movement of the partition 13, and when it is to be removed, the partition 13 can be taken out from the receiving groove from bottom to top.

[0043] When the spacing between the columns 12 is large, multiple partitions 13 can be installed, and the multiple partitions 13 can be spliced ​​together to enclose the area between the columns 12.

[0044] Please see Figure 2 and Figure 4 In some possible embodiments, each precast concrete base 11 is provided with a column 12, and the column 12 is located in the middle of the precast concrete base 11. A partition 13 is provided between two adjacent columns 12, and the two sides of the partition 13 are respectively located above the two adjacent columns 12. This can improve the structural stability of the precast concrete base 11, the column 12 and the partition 13, and prevent relative movement between two adjacent columns 12.

[0045] Please see Figures 2 to 4 , Figure 8 In some possible embodiments, a first embedded part 112 is provided on the top of the precast concrete base 11. The first embedded part 112 is a metal part used for detachable connection with the column 12. The specific shape and structure of the first embedded part 112 are not limited. The main body of the first embedded part 112 is located in the precast concrete base 11. The first embedded part 112 has a mounting plate exposed to the precast concrete base 11. The mounting plate and the column 12 are detachably connected by bolts.

[0046] Please see Figure 3 and Figure 6 In some possible embodiments, the enclosure unit 10 further includes a horizontal support rod 14 and a diagonal brace 15. The horizontal support rod 14 is located on the side of the precast concrete base 11 adjacent to the construction area and extends in a horizontal direction perpendicular to the precast concrete base 11. The horizontal support rod 14 is provided in a one-to-one correspondence with the column 12 and is located in the same vertical plane. One end of the diagonal brace 15 is connected to the end of the horizontal support rod 14 away from the precast concrete base 11, and the other end is connected to the column 12.

[0047] The uprights 12, diagonal braces 15, and horizontal support rods 14, as load-bearing components, can all be made of steel. The diagonal brace 15 can be a single rod or a telescopic rod with manually adjustable length. The diagonal brace 15, horizontal support rods 14, and uprights 12 form a triangular stable structure that can prevent the enclosure unit 10 from tipping over.

[0048] like Figure 3As shown, when the diagonal brace 15 is a telescopic rod, it includes a support rod body, a screw rod, and an adjusting nut. The support rod body is located at the bottom, with its bottom end hinged to the horizontal support rod 14. The lower end of the screw rod is slidably engaged with the support rod body, and its upper end is hinged to the column 12. The adjusting nut is threadedly engaged with the screw rod; rotating the adjusting nut locks the screw rod and support rod body in place. When disassembly is required, rotating the adjusting nut in the opposite direction allows relative movement between the screw rod and support rod body.

[0049] Please see Figure 9 In some possible embodiments, a second embedded part 113 is provided on the side of the precast concrete base 11. The second embedded part 113 is used to be detachably connected to the horizontal support rod 14. The second embedded part 113 can adopt a structure similar to the first embedded part 112 described above. The main body of the second embedded part 113 is embedded in the precast concrete base 11.

[0050] Please see Figure 7 and Figure 8 In some possible embodiments, the connecting unit 30 includes an anchoring clamp 31 and a locking sleeve 32. The anchoring clamp 31 has a threading channel for the tension rope 20 to pass through. The anchoring clamp 31 includes a connecting part 311 and a clamping part 312 connected in sequence. The connecting part 311 is used to abut against the enclosure unit 10. The clamping part 312 is located on the side of the connecting part 311 away from the enclosure unit 10. The outer surface of the clamping part 312 is a conical surface, and the diameter of the conical surface gradually decreases in the direction away from the connecting part 311. The end of the clamping part 312 has a plurality of notches 3121 evenly spaced along its circumference. The notches 3121 extend along the axial direction of the clamping part 312 and divide the clamping part 312 into a plurality of clamping claws. The locking sleeve 32 is sleeved on the outer periphery of the anchoring clamp 31. The locking sleeve 32 has a threaded inner hole that is threadedly engaged with the outer surface of the connecting part 311 and a conical inner hole that is slidably engaged with the outer surface of the clamping part 312. The conical inner hole and the threaded inner hole are axially connected.

[0051] The tensioning rope 20 passes through the anchoring clamp 31. When tensioning prestress is applied to the tensioning rope 20 using mechanical equipment such as a tensioning jack, the locking sleeve 32 is in a loose state, and the tensioning rope 20 can move relative to the clamping part 312.

[0052] When it is necessary to fix the anchoring clamp 31 and the tension rope 20, rotate the locking sleeve 32 so that the conical inner hole of the locking sleeve 32 pushes the multiple clamping claws of the clamping part 312 closer to each other, and the clamping claws can clamp and fix the tension rope 20.

[0053] When it is necessary to remove the tension rope, rotate the locking sleeve 32 in the opposite direction to separate the anchoring clamp 31 from the tension rope 20. The prestress of the tension rope 20 is released and it returns to its original length, so that the tension rope 20 can be pulled out from the clearance hole 111.

[0054] It should be noted that the structure and usage of the above-mentioned connecting unit 30 is only one implementation method included in the embodiments of this application. In actual use, the connecting unit 30 can also adopt other clamps and locking components in the prior art that can fix and connect ropes.

[0055] Please see Figure 4 and Figure 5 In some possible embodiments, the road construction enclosure also includes a water spraying dust suppression unit 40 disposed on top of the enclosure unit 10 along the connection direction. The water spraying dust suppression unit 40 includes a water pipe and a nozzle. The water pipe is connected to a water pump, which delivers water and sprays water mist onto the surrounding area through the nozzle to suppress dust.
