Description

Technical Field

[0001] The utility model relates to the technical field of guardrails, in particular to a temporary guardrail for highway construction. Background Technique

[0002] When a highway is under construction, a guardrail is needed for maintenance to prevent pedestrians and motor vehicles from straying in and causing danger. At present, in order to maintain the stability of the guardrail, the common guardrails are those with support feet on both sides of the guardrail. Such support will occupy the ground space on both sides. Therefore, the support feet of the guardrail will protrude on one side outside the construction guardrail, which will trip pedestrians and non-motor vehicles. For this reason, we propose a temporary guardrail for highway construction. Content of the Utility Model

[0003] The main purpose of the utility model is to provide a temporary guardrail for highway construction, which can effectively solve the problems in the background technique.

[0004] To achieve the above purpose, the technical solution adopted by the utility model is as follows:

A connection and transmission structure is inserted in the guardrail. Weight-increasing structures are fixedly installed on the upper surfaces of the stable support bottom plates.

[0006] Further, the connection and transmission structure includes a water conduit, a connecting external screw ring, a limiting retaining piece, a plug connector, and a connecting internal screw ring. One end of the water conduit is fixedly connected to the connecting external screw ring. The other end of the water conduit is fixedly connected to the plug connector. A limiting retaining piece is fixedly installed at the connection between the water conduit and the plug connector. A connecting internal screw ring is sleeved and installed at a position near one end of the water conduit surface close to the plug connector.

[0007] Further, the connecting internal screw ring is arranged to match the connecting external screw ring, and a sealing gasket is fixedly installed on the connecting surface of the limiting retaining piece.

[0008] Further, the weight-increasing structure includes a rubber bladder, a discharge port, a screw plug, and a shunt conduit. The discharge port is fixedly installed on the side of the rubber bladder near the lower surface. The discharge port is hermetically sealed with a screw plug. The upper surface of the rubber bladder is connected to the shunt conduit.

[0009] Further, the rubber bladder is communicated with the water conduit through the shunt conduit.

[0010] Compared with the prior art, the utility model has the following beneficial effects:

[0011] In the present utility model, the temporary guardrail for road construction can connect the guardrails, increase the pressure on the inner support feet of the guardrail, lower the center of gravity of the guardrail, ensure its stability, and avoid the problem that pedestrians or non-motor vehicles may trip over the support feet arranged on the outer side of the guardrail, making it safer and more reliable, and also very simple and convenient to install.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0017] In order to make the technical means, creative features, achieved purposes and functions of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0018] As Figures 1-4 shown, the temporary guardrail for road construction includes a guardrail 1. Stable support bottom plates 2 are fixedly installed on both support feet at the lower end of the guardrail 1. A connection and transmission structure 3 is inserted into the guardrail 1. Weight increasing structures 4 are fixedly installed on the upper surfaces of the stable support bottom plates 2;

[0019] The connection and transmission structure 3 includes a water conduit 301, a connecting external screw ring 302, a limit retaining piece 303, a plug connector 304, and a connecting internal screw ring 305. One end of the water conduit 301 is fixedly connected to the connecting external screw ring 302, and the other end of the water conduit 301 is fixedly connected to the plug connector 304. A limit retaining piece 303 is fixedly installed at the connection between the water conduit 301 and the plug connector 304. A connecting internal screw ring 305 is sleeved and installed at a position on the surface of the water conduit 301 near one end of the plug connector 304. The connection and transmission structure 3 connects multiple guardrails, greatly improving the stability of the entire guardrail; the connecting internal screw ring 305 is arranged to match the connecting external screw ring 302, and a sealing gasket is fixedly installed on the connection surface of the limit retaining piece 303; the weight increasing structure 4 includes a rubber bladder 401, a discharge port 402, a screw plug 403, and a shunt conduit 404. A discharge port 402 is fixedly installed on the side surface of the rubber bladder 401 near the lower surface. A screw plug 403 is hermetically screwed in the discharge port 402. The upper surface of the rubber bladder 401 is connected to the shunt conduit 404. Removing the screw plug 403 and opening the discharge port 402 can drain the water in the rubber bladder 401, reducing the gravity during handling when retracted; the rubber bladder 401 is communicated with the water conduit 301 through the shunt conduit 404.

[0020] It should be noted that the present utility model is a temporary guardrail for highway construction. During installation, the connection and transmission structures 3 on multiple guardrails 1 are connected end to end. When connecting, the plug connector 304 on the first guardrail is inserted into the hole of the connecting external screw ring 302 on the second guardrail, and then the connecting internal screw ring 305 on the first guardrail is screwed onto the connecting external screw ring 302 of the second guardrail for fixed connection. In this way, the splicing of multiple guardrails can be completed. After splicing, the end port of the last spliced guardrail is blocked. Then, the port of the connecting external screw ring 302 of the first guardrail is connected to a water injection pump. The water injection pump first rotates in reverse to extract all the air in the rubber bladder 401, the shunt conduit 404, and the water conduit 301, and then rotates forward to inject water into the rubber bladder 401 through the water conduit 301 and the shunt conduit 404. The purpose of extracting the gas is to avoid the situation where the internal air cannot be discharged, resulting in the inability to fill the inside with water. After filling with water in this way, the pressure of the water can firmly press the stable support base plate 2 on the ground, thereby preventing the guardrail 1 from falling down, increasing the stability and also avoiding the disadvantages brought by setting supports outside the guardrail.

[0021] The above shows and describes the basic principles, main features, and advantages of the present utility model. Those skilled in the art should understand that the present utility model is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principles of the present utility model. Without departing from the spirit and scope of the present utility model, the present utility model will have various changes and improvements, and these changes and improvements all fall within the scope of the present utility model claimed. The scope of protection claimed by the present utility model is defined by the appended claims and their equivalents.
