Description

Technical Field

[0001] This application relates to the field of construction fencing technology, and in particular to a temporary fencing for highway construction. Background Technology

[0002] Municipal roads often require road surface protection. During the road surface protection process, temporary fences need to be erected to separate the normal driving road surface from the construction road surface in order to warn passing vehicles and protect the safety of construction workers.

[0003] Current temporary fencing has the following drawbacks. On the one hand, it usually adopts a unit-type or rod-type assembly structure, which requires the use of expansion bolts to fix it to the normal road surface to ensure stability. This increases the amount of construction work involved in disassembly and assembly, and damages the normal road surface. Repairs are required after disassembly. On the other hand, a large amount of dust is easily generated during construction, and temporary fencing is usually not equipped with dust suppression equipment. The dust generated during construction can easily affect the health of construction workers.

[0004] The prior art disclosed in CN116291025A is an easy-to-install and dismantle automatic sprinkler dust suppression water-saving enclosure, which can increase the counterweight by storing water in the base box at the bottom and provide a water source for the sprinkler dust suppression structure. However, the sprinkler dust suppression water-saving enclosure in this prior art is an integral structure, which is inconvenient to disassemble and transport.

[0005] Therefore, the issues of convenient disassembly, assembly, and transportation need to be addressed in the temporary fencing structures for water storage and sprinkler systems. Utility Model Content

[0037] Example

[0038] This embodiment provides a temporary fence for highway construction, referring to... Figure 1 As shown, it includes a counterweight unit 1, a fence unit 2, and a sprinkler assembly.

[0039] Specifically, the counterweight 1 has a water storage space inside. The counterweight 1 has a water inlet and a water outlet communicating with the water storage space. Water is added to the water storage space through the water inlet to increase the water volume. The fence section 2 is detachably connected to the top of the counterweight 1. When transporting the temporary fence, the counterweight 1 and fence section 2 can be separated and stacked separately for convenient transportation. When installing the temporary fence, the counterweight 1 and fence section 2 are reassembled.

[0040] Specifically, the spray assembly includes a water pump 31 and a spray pipe 32. The water pump 31 is mounted on the counterweight 1 and is connected to the storage space. The spray pipe 32 is mounted on the top of the enclosure 2 and connected to the water pump 31; the spray pipe 32 is equipped with multiple atomizing nozzles 33. By using the spray assembly to reduce dust, the health impact of dust on construction workers can be reduced. Since the spray pipe 32 is mounted on the enclosure 2 and the water pump 31 is mounted on the counterweight 1, there is no need to disassemble the spray pipe 32 and the water pump 31. During on-site construction, only the counterweight 1 and the enclosure 2 need to be assembled, and the water pump 31 needs to be connected to the spray pipe 32, thus reducing the amount of construction work.

[0041] In this embodiment, by storing water in the water storage space of the counterweight 1, the stability of the temporary fence can be enhanced on the one hand, and some of the stored water can also be used as water for spraying on the other hand, achieving multiple benefits.

[0042] Specifically, refer to Figure 2 and Figure 3 As shown, the fence section 2 includes a support rod 21 and multiple fence units 22. Adjacent fence units 22 are movably connected in the vertical direction, forming a vertically telescopic structure. During transportation, the individual fence units 22 can be retracted and stacked, reducing the space occupied and improving transportation convenience. The support rod 21 is connected to the first and last fence units 22 via pins 23, respectively, to support the extension of each fence unit 22. At the construction site, the support rod 21 provides support so that the fence units 22 can be unfolded to form protection.

[0043] Specifically, refer to Figure 2 As shown, the fence unit 22 includes a vertical tube 221 and a horizontal rod 222. The two ends of the horizontal rod 222 are respectively connected to the vertical tube 221. One end of the vertical tube 221 is provided with a first limiting member 223 extending from the inner wall toward the axis, and the other end is provided with a second limiting member 224 extending from the outer wall away from the axis. That is, both ends of the vertical tube 221 are open, with the limiting member at one end extending inward and the limiting member at the other end extending outward. The vertical tubes 221 of adjacent fence units 22 are arranged in a nested configuration, such that the first limiting member 223 and the second limiting member 224 abut and restrict separation. In two adjacent fence units 22, one vertical tube 221 is nested on the other, allowing the two vertical tubes 221 to move relative to each other along the axial direction, i.e., the vertical direction, forming a telescopic shape. The first limiting member 223 and the second limiting member 224 abut against each other to prevent the two adjacent vertical tubes 221 from vertically separating.

[0044] Reference Figure 3 As shown, when multiple fence units 22 are in the unfolded state, support rods 21 are inserted into each vertical tube 221. Since the two ends of the support rods 21 are connected to the vertical tube 221 of the first fence unit 22 and the tail fence unit 22 respectively through pins, under the cooperation of the first limiting member 223 and the second limiting member 224, each fence unit 22 can maintain a stable state.

[0045] Specifically, refer to Figure 4 and Figure 5As shown, mounting plates 11 are provided at both ends of the counterweight 1. Each mounting plate 11 has a through hole; the vertical tube 221 of the rear fence unit 22 abuts against the top of the mounting plate 11; the support rod 21 passes through the through hole and is connected to a nut 12. By abutting the vertical tube 221 against the mounting plate 11, and connecting the nut 12 to the support rod 21 and abutting against the mounting plate 11, the fence unit 2 can be detachably mounted on the counterweight 1. The assembly and disassembly method is relatively simple and convenient. The nut 12 can be connected to the support rod 21 by providing an external thread.

[0046] The temporary fencing for highway construction provided in this embodiment, by storing water in the counterweight part 1 to increase the counterweight and improve stability, and by providing water for the sprinkler assembly, allows the fencing part 2 to be detachably connected to the counterweight part 1. The fencing part 2 is composed of multiple fencing units 22 and support rods 21. The multiple fencing units 22 can be folded or extended, and in the folded state, they are convenient for stacking and transportation. During installation, the support rods 21 can support each fencing unit 22 to unfold and form protection. After inserting the support rods 21 into the through holes on the mounting plate 11, the fencing part 2 can be installed using nuts 12. The installation and disassembly processes are relatively simple and convenient.

[0047] Specifically, the support rod 21 has an axially extending water supply channel 211 inside; one end of the support rod 21 is connected to the spray pipe 32 via a first flexible hose 34, and the other end is connected to the water pump 31 via a second flexible hose 35; thus, the water pump 31 and the spray pipe 32 are connected through the water supply channel 211. By using the water supply channel 211 inside the support rod 21 to connect the spray pipe 32 and the water pump 31, no external water pipe structure is required, reducing additional construction work.

[0048] In this embodiment, the water pump 31 is positioned on the side of the counterweight 1 and below the mounting plate 11. The support rod 21 passes through the mounting plate 11 and is connected to the water pump 31 and the support rod 21 via a flexible hose. This ingenious structural layout reduces additional workload.

[0049] In this embodiment, a quick connector is used to connect the hose to the water pump 31 or the spray pipe 32, or it can be simply fixed with wire.

[0050] Specifically, the support rod 21 has pin holes at both ends to accommodate the pin rod 23, and these pin holes are not connected to the water supply channel 211. The pin hole is a tubular structure, separating it from the water supply channel 211 to prevent water leakage.

[0051] Specifically, refer to Figure 6As shown, the pin rod 23 includes a first rod body and a second rod body; the first rod body and the second rod body are connected and form an angle; the second rod body is provided with a limiting hole; a limiting pin 24 is inserted into the limiting hole. When the second rod body passes through the vertical pipe support rod 21, the limiting pin 24 is inserted into the limiting hole to prevent the pin rod 23 from coming out.

[0052] Specifically, the top of the first fence unit 22 is provided with multiple support frames 25, and each support frame 25 is provided with a locking slot 26; the sprinkler pipe 32 is locked in the locking slot 26. This facilitates the disassembly of the sprinkler pipe 32 from the first fence unit 22.

[0053] Specifically, the spray direction of the atomizing nozzle 33 is obliquely upward, resulting in a larger spray range.

[0054] Specifically, the counterweight 1 is equipped with a transparent water level warning line 13. The water level warning line 13 allows for the observation of the stored water, enabling timely replenishment of water.

[0055] In actual use, the spray volume of a single temporary fence is small, and the spraying rule is generally spraying for ten minutes every hour. Therefore, the water stored in the water storage space can meet the long-term spraying needs and does not require frequent water replenishment.

[0056] Usage process: Stack the counterweight 1 and the fence 2 and transport them to the construction area. Place the counterweight 1 in the designated area and replenish water to each counterweight 1 in sequence. Pass the support rod 21 through each fence unit 22 and use the pin rod 23 to connect the vertical tube 221 of the first fence unit 22 and the vertical tube 221 of the last fence unit 22 to the support rod 21. Then insert the support rod 21 into the through hole of the mounting plate 11 and tighten the nut 12 to complete the assembly of the counterweight 1 and the fence 2. Finally, use the hose to connect the support rod 21 to the water pump 31 and the sprinkler pipe 32 respectively.

[0057] When spraying is required, the water supply pump 31 is started to transport water from the water storage space to the spray pipe 32 for spraying. Water should be replenished promptly when the water level falls below the warning line 13. In actual construction, replenishment can also be carried out at a unified time.

[0058] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0059] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
