Description
Technical Field
The utility model belongs to the technical field of traffic gas appliances, more specifically says, in particular to novel concrete anticollision mound protective film shell.
Background
The anti-collision pier is also called an anti-collision guardrail and is a pavement facility which is arranged at two sides or the center of a highway and used for preventing vehicles from passing through and rushing out of a pavement area. Many anti-collision piers are formed by pouring concrete, and are provided with reinforcing bars for increasing the anti-collision grade. According to investigation, after the concrete anti-collision pier in the northern area is used for several years, the concrete anti-collision pier is often stripped and damaged within 20cm of the root of the anti-collision pier, and in the serious case, reinforcing steel bars are exposed, so that the anti-collision grade is reduced, and the attractiveness is seriously reduced. The reason is that the deicing salt and the snow melting agent sprayed in the snowy days in winter contain a large amount of corrosive ions and chloride ions, and vehicles run by the deicing salt and the snow melting agent to sputter the corrosive ions and the chloride ions onto the anti-collision piers. Because a large number of capillary holes exist on the surface and inside of the concrete, corrosive ions and chloride ions can slowly permeate into the concrete, the chloride ions serving as a catalyst can damage a steel bar passivation film to cause corrosion, and the corroded steel bars can expand and damage a concrete protective layer from the inside. On the other hand, the anti-collision pier also bears the freeze-thaw cycle damage effect, when the environmental temperature is reduced below zero, the adsorbed free water in the capillary pores of the concrete anti-collision pier can be frozen, the volume of the water in the process of converting the water into ice is increased by 11%, the expansion process is an expansion process, and if the water is frozen again after thawing, the expansion is continuously increased, and finally the concrete can be peeled and damaged.
In order to solve the problem, someone adopts the guard plate of outer subsides 3 ~ 5cmm thickness to strengthen the protection to crashproof mound, and the concrete scheme is: the protection plate is of a split structure and consists of an upper plane plate and a lower arc panel. A mortar leveling layer is smeared between the upper plane plate and the anti-collision pier, and then a metal long bolt penetrates through the protection plate and is screwed into a threaded sleeve in the anti-collision pier for fixing; and the lower cambered surface plate is bonded with the cambered surface at the bottom of the anti-collision pier by plastering mortar.
Based on the above, the present inventors found that the following problems exist: firstly, the method comprises the following steps: the bolt is adopted to fix the upper plane plate, the exposed bolt head is gradually reduced due to corrosion, and finally the function of fixing the upper plane plate and the anti-collision pier cannot be borne, so that the upper plane plate falls off to cause great safety threat to road traveling, and the situation occurs; secondly, the method comprises the following steps: the lower cambered plate and the anti-collision pier are not reliably bonded by adopting a mortar bonding mode, the mortar bonding force is weakened and lost due to various reasons along with the prolonging of the service time, and the lower cambered plate can also fall off to cause great threat to road traveling.
Therefore, in view of the above, research and improvement are performed on the existing structure and defects, and a novel concrete anti-collision pier protective membrane shell is provided, so as to achieve the purpose of higher practical value.
SUMMERY OF THE UTILITY MODEL
In order to solve the technical problem, the utility model provides a novel concrete anticollision mound protective film shell to solve present guard plate and receive the problem that easily drops after corroding.
The utility model discloses purpose and efficiency of concrete anticollision mound protective film shell are reached by following concrete technical means:
the utility model provides a novel concrete anticollision mound protective film shell, includes the anticollision mound, the surperficial one side of anticollision mound is opened the chisel and is had a plurality of groups mounting hole, and installs a plurality of expansion bolts in the mounting hole, the protective film shell is installed to one side of anticollision mound, a plurality of groups of pre-buried bolts are installed in one side that is close to the anticollision mound to the protective film shell, all be equipped with the screw thread on pre-buried bolt and expansion bolt's the outer wall, just pre-buried bolt on the protective film shell with the expansion bolt that the anticollision mound surface was equipped with is connected through the grout material.
Further, the shape of the protective film shell is the same as the outline of the working surface of the anti-collision pier.
Furthermore, sealing waterproof materials are filled at the joint of the two sides and the bottom end of the gap between the protective film shell and the anti-collision pier.
Furthermore, the top in gap between protective film shell and the anticollision mound is equipped with the opening, pour the grout material in the opening, and the grout material is any one of cement base grout material and organic resin class grout material.
Furthermore, the surface of the protective film shell is coated with anticorrosive paint.
Compared with the prior art, the utility model discloses following beneficial effect has:
the utility model discloses, through the mechanical anchoring effect with expansion bolts and pre-buried bolt after the grout material sclerosis, can assemble the surface of anticollision mound with the protection mould shell, be different from traditional split type design and bolt fastening's operation mode, make the protective film shell firmly fixed with the anticollision mound, the threat of having avoided the protective film shell to drop to traffic driving safety causes, and pre-buried bolt is in the surperficial bolt-free hole that makes the protective film shell in the protective film shell, reduce external factor and corrode pre-buried bolt, protective film shell and the packing of anticollision mound laminating department have sealing material, further prevent that the hydrone from entering into between protective film shell and the anticollision mound from the gap, thereby corrode expansion bolts and pre-buried bolt, improve the holistic life of protective film shell, reduce the traffic hidden danger.
