Description

Technical Field

[0001] The invention relates to the field of highway safety structures, and in particular to an ultra-high performance rubber concrete anti-collision guardrail. Background Art

[0002] Highway guardrails are guardrails installed on both sides or in the middle of the highway. When a vehicle collides with it, the guardrail can absorb the collision energy and prevent the vehicle from rushing into other lanes. While making it less likely for the vehicle to be destroyed, it can also provide better protection for the vehicle and the driver and passengers.

[0003] Existing guardrails are mostly metal guardrails and concrete guardrails. Metal guardrails deform when facing a vehicle collision. Severe collisions will cause the guardrails to break at the connection, making it impossible to stop the vehicle. The vehicle will fly off the road and cause secondary falling injuries to the driver and passengers. Concrete guardrails have two extremes. One is that the thickness is too large and the vehicle impact cannot absorb the energy, causing greater impact injuries to the driver and passengers. The other is that the thickness is too small and has no stopping effect at all.

[0004] To this end, we propose an ultra-high performance rubber concrete anti-collision guardrail. Summary of the invention

[0005] In view of the above-mentioned deficiencies in the prior art, the present invention provides an ultra-high performance rubber concrete anti-collision guardrail.

[0006] In order to achieve the above-mentioned object of the invention, the technical solution adopted by the present invention is:

[0007] An ultra-high performance rubber concrete anti-collision guardrail, comprising:

[0008] The guardrail body is provided with a plurality of guardrail bodies, each of which includes an outer cylinder and an inner cylinder arranged inside the outer cylinder. The plurality of guardrail bodies are fixedly connected, a rubber concrete layer is filled between the inner cylinder and the outer cylinder, and the bottoms of the inner cylinder and the outer cylinder are fixed to the ground;

[0009] The pulling component is arranged in the inner tube, and is used to pull the inside of the guardrail body and between adjacent guardrail bodies to prevent the guardrail body from being disconnected.

[0010] By configuring the guardrail body to be an outer tube and an inner tube, and filling a rubber concrete layer between the outer tube and the inner tube, and arranging a pulling component in the inner tube, pulling is achieved on the guardrail body itself and between adjacent guardrail bodies. When the guardrail body is hit by a vehicle, the outer tube and the rubber concrete will form a preliminary energy absorption, and when the guardrail body is deformed toward the outside of the highway, due to the action of the internal pulling component, the guardrail body will not break, the pulling component will have a stopping effect on the vehicle, and the pulling component in the guardrail body that has been hit will stop the vehicle, and the pulling component in the adjacent guardrail body will also achieve a reaction force on the pulling component in the guardrail body that has been hit, thereby improving the stopping effect, effectively preventing the vehicle from rushing out of the highway and causing secondary falling injuries to the driver and passengers, and being safer.

[0011] It is further defined that each guardrail body includes an upper cross bar, a lower cross bar and two vertical poles, and the upper cross bar, the lower cross bar and the vertical poles all include an inner tube and an outer tube; the vertical poles are inserted into the ground and fixed, and the upper cross bar and the lower cross bar are horizontally arranged between the two vertical poles and are connected to the vertical poles.

[0012] It is further defined that the pulling assembly includes a middle pull rope, side pull ropes, adjacent pull ropes and force springs; the middle pull rope is arranged in the inner tube of the upper cross bar and the lower cross bar, the inner ends of the two force springs are fixedly connected to the two ends of the middle pull rope, the side pull ropes are arranged in the inner tube of the vertical pole, and the two ends are respectively fixedly connected to the outer ends of the force springs in the upper cross bar and the lower cross bar, and the two ends of the adjacent pull ropes are respectively connected to the outer ends of two force springs at the same height in two adjacent guardrail bodies; when the impact position is on the lower cross bar, the middle pull rope, side pull ropes and adjacent pull ropes in the upper cross bar will form a pulling reaction force on the middle pull rope in the lower cross bar, and when the impact position covers the upper cross bar and the lower cross bar at the same time, the middle pull rope in the upper cross bar and the middle pull rope in the lower cross bar will form a pulling reaction force with each other, and at the same time, the adjacent pull ropes on both sides will also form a pulling reaction force on the middle pull rope.

[0013] A middle pull rope is set in the upper cross bar and the lower cross bar of the guardrail body. When a vehicle with a lower front end only hits the lower cross bar, the lower cross bar is bent and deformed outward, and the middle pull rope in the lower cross bar is bent outward due to the impact force. At this time, the middle pull rope and the side pull rope in the upper cross bar are not subjected to the impact force, so they will give a reaction force to prevent them from bending and deforming. The adjacent pull rope will also give a reaction force to the hit middle pull rope, thereby improving the stopping effect. When the upper cross bar and the lower cross bar are installed on the front of the vehicle at the same time, the middle pull ropes in the upper cross bar and the lower cross bar are bent outward due to the impact force, and the forces of the two will conflict with each other, forming a stopping force for the vehicle. The force spring is deformed when it is hit or pulled to achieve energy absorption, which avoids the excessive rigidity of the pull rope interception, thereby improving the safety of stopping and preventing the driver and passengers from causing excessive impact injuries in the vehicle.

[0014] It is further defined that guide rods are provided on the vertical poles corresponding to the upper and lower corners of each side pull rope, and both ends of the guide rods are provided on the inner tube and outer tube of the vertical pole; guide rods are provided at the corners of the side pull rope, and the side pull rope is sleeved on the guide rods at the corners. This arrangement makes the side pull rope smoother when pulled at the corners.

[0015] It is further defined that the road side of the pole is covered with a buffer pad with a deformation function, the inner surface of the buffer pad matches the surface of the pole, and the outer surface is a cylindrical surface, and the end of the guide rod on the road side located at the lower part of the pole passes through the outer cylinder of the pole and is inserted into the buffer pad to fix the buffer pad; covering the buffer pad on the road side of the pole can enable the vehicle to absorb energy when it hits the pole, and the buffer pad on the cylindrical surface can also realize a function of forcing the vehicle to turn obliquely. The buffer pad is fixed by the end of a guide rod, which can not only ensure that the buffer pad will not fall off under normal circumstances, but also absorb energy and fall off very easily during collision, playing the same role as a rotating drum.

[0016] It is further defined that an "X"-shaped reinforcement frame is provided in the rectangular frame formed by the upper horizontal bar, the lower horizontal bar and the two vertical bars, and the four ends of the reinforcement frame are respectively fixedly connected to the four corners of the rectangular frame; providing a reinforcement frame can prevent the tensile force caused by the impact from causing the rectangular frame to collapse directly in the middle when it is impacted, thereby improving stability.

[0017] It is further defined that the outer diameter of the force tension spring matches the inner diameter of the inner tube, pull rings are provided at both ends of the force tension spring, pull hooks are provided at both ends of the middle pull rope, pull hooks are also provided at both ends of the side pull rope and the adjacent pull rope, and the ends of the side pull rope and the adjacent pull rope on the same side are jointly arranged on one pull hook; such an arrangement of the force tension spring can fix and unify the height of the internal pull rope, and the connection and fixing structure through the pull hook and the pull ring is simple and convenient.

[0018] It is further defined that grouting holes and overflow holes are respectively provided on both sides of the outer tube of the upper cross bar; an overflow exhaust valve is provided in the overflow hole; the grouting hole is arranged in the middle part of the upper cross bar, which is more convenient for grouting, and each guardrail body is grouted separately for easy maintenance, and an overflow exhaust valve is provided for exhaust during grouting.

[0019] It is further defined that the overflow exhaust valve comprises an upper shell, a lower shell, a valve plate, a valve stem, a clamping plate and a return spring; the lower shell is a cylindrical tube with a closed top, and the bottom is fixed to the outer tube of the upper cross bar, the valve plate is fixedly connected to the bottom of the valve stem, the top end of the valve stem is arranged through the top of the lower shell, the clamping plate is fixedly connected to the top end of the valve stem, the return spring is passed through the valve stem and is located in the lower shell, and when the clamping plate contacts the top surface of the lower shell and the bottom surface of the valve plate is flush with the inner wall of the outer tube of the upper cross bar, the return spring is in an uncompressed state;

[0020] The upper shell is a rectangular box with a closed top. The bottom of the upper shell is fixed to the top of the lower shell. The outer diameter of the card plate matches the inner diameter of the upper shell. Exhaust holes are correspondingly opened in the valve plate, the valve stem and the card plate. The gas outlet of the exhaust hole is arranged on one side wall of the card plate. An exhaust port is opened on the side wall of the upper shell at the position corresponding to the exhaust hole, and the position of the exhaust port is higher than the position of the exhaust hole.

[0021] Exhaust holes are arranged in the valve plate, valve stem and clamping plate, and an exhaust port is opened on the side wall of the upper shell body. During the grouting process, the slurry will squeeze out the internal gas, and the gas will form pressure on the valve plate, causing the return spring to compress, and the valve plate and the clamping plate to rise until the exhaust hole and the exhaust port are aligned to implement exhaust. After the exhaust is completed, the slurry is continuously injected, and the pressure increases, forcing the return spring to further compress, and the exhaust hole and the exhaust port are offset to achieve internal closure. This arrangement can improve the density of the internal slurry and prevent the occurrence of unfilled cavities.

[0022] It is further defined that an observation window extending to the lower shell is vertically opened on the upper shell, the observation window and the exhaust port are opened on different side walls, and the spring coefficient k of the return spring must satisfy:

[0023]

[0024] Among them, l 气 F is the vertical distance between the exhaust hole and the exhaust port when the return spring is not compressed. 气 is the gas pressure inside the upper crossbar on the valve plate, f is the friction between the valve plate and the upper shell; and

[0025]

[0026] Among them, l 排 F is the diameter length of the exhaust hole, 浆 is the rubber concrete slurry pressure on the valve plate; where:

[0027] F 浆 =P 浆 s;

[0028]

[0029] Among them, P 注 is the grouting pressure at the grouting port, s is the pressure area of ​​the valve plate, f 浆 is the friction coefficient between the rubber concrete slurry and the outer tube of the upper cross bar, L is the horizontal distance between the grouting port and the valve plate, D is the equivalent inner diameter of the outer tube of the upper cross bar, ρ is the density of the rubber concrete slurry, and v is the flow rate of the rubber concrete slurry.

[0030] Such setting of the return spring can ensure that the internal exhaust and sealing functions after exhaust are completed during the grouting process under the grouting pressure, so as to prevent the appearance of gaps inside the guardrail body that are not filled with slurry.

[0031] The beneficial effects of the present invention are as follows: by setting a pulling component, pulling can be achieved inside the guardrail body and adjacent guardrail bodies, which has a better effect of stopping the vehicle when it is hit, and the force tension spring and the rubber concrete layer can absorb energy from the vehicle impact and reduce the impact damage.

When the guardrail body 1 is hit by a vehicle, the outer tube and the rubber concrete will form a preliminary energy absorption. When the guardrail body 1 is deformed toward the outside of the road, due to the action of the internal pulling component 2, the guardrail body 1 will not break.

The adjacent pull rope 23 will also give a reaction force to the hit middle pull rope 21, thereby improving the stopping effect.

A function of forcing a turn is realized; the buffer pad 4 is fixed by the end of a guide rod 3, which can ensure that the buffer pad 4 will not fall off at ordinary times, and can absorb energy and fall off very easily when impacted, playing the same role as the rotating drum; a reinforcing frame 5 is set to prevent the tensile force caused by the impact from causing the enclosed rectangular frame to collapse directly to the middle when impacted, thereby improving stability; the force-applying tension spring 24 is set in this way to fix the height of the internal pull rope, and the connection and fixing structure is simple and convenient to connect through the hook 26 and the pull ring 25; the grouting hole 15 is set in the middle of the upper cross bar 11, which is more convenient for grouting, and each guardrail body 1 is grouted separately for easy maintenance, and an overflow exhaust valve 16 is set to exhaust during grouting;An exhaust hole 167 is provided in the valve plate 163, the valve stem 164 and the card plate 165, and an exhaust port 168 is provided on the side wall of the upper shell 161. During the grouting process, the slurry will squeeze out the internal gas, and the gas will form pressure on the valve plate 163, causing the return spring 166 to compress, and the valve plate 163 and the card plate 165 rise until the exhaust hole 167 and the exhaust port 168 are aligned to perform exhaust. After the exhaust is completed, the slurry is continuously injected, and the pressure increases, forcing the return spring 166 to further pressurize, and the exhaust hole 167 and the exhaust port 168 are staggered to achieve sealing inside. This setting can improve the density of the internal slurry and prevent the occurrence of unfilled cavities; the return spring 166 is set in this way to ensure that the exhaust and sealing functions after exhaust are completed during the grouting process under the grouting pressure, so as to prevent the appearance of gaps not filled with slurry inside the guardrail body 1. ;
