Description

Technical Field

[0001] The utility model belongs to the field of traffic safety protection, and particularly relates to a transition section structure without wing walls. Background Technique

[0002] Highway guardrails mainly consist of roadside guardrails, median guardrails, bridge guardrails, and transition sections between guardrails. If the protection ability of any component fails to meet the requirements, it will leave potential safety hazards. Currently, in the design of highway guardrail transition sections in China, the transition section structure between the corrugated beam guardrail on the subgrade and the concrete bridge guardrail has relatively large safety hazards.

[0003] Currently, in practical applications, there are generally two treatment methods for the transition section. The first method is to directly lap the corrugated beam plate with the concrete guardrail. For the corrugated beam directly anchored to the concrete bridge guardrail, since no transition wing wall is designed, the inner side of the bridge guardrail and the corrugated beam are not in the same plane, resulting in violent distortion construction of the corrugated plate and more on-site cutting and trimming, further reducing the protection ability of the guardrail transition section. The second method is to adopt the concrete wing wall transition form recommended in the "Design Rules", but during the construction process of the concrete wing wall transition section, there are problems such as long construction period, difficult control of construction quality, and high risk of high-altitude operations.

[0004] Based on the above situation, a transition section structure without wing walls is proposed. The safety performance of this transition section meets the requirements of the "Highway Guardrail Safety Performance Evaluation Standard" (JTG B05-01—2013). This structure is convenient for construction and installation and can better maintain the operation safety of highways. Content of the Utility Model

[0005] The purpose of the utility model is to provide a transition section structure without wing walls to solve the construction problems of the transition section between the corrugated beam guardrail on the subgrade and the concrete bridge guardrail.

[0006] To achieve the above technical purpose, the technical solution of the utility model is realized as follows:

[0007] A transition section structure without wing walls includes high-strength three-wave plates, transition section cross beams, strengthening columns, and transition section friction beams. The high-strength three-wave plates are welded by three-wave plates and three-wave lap plates. One end of the high-strength three-wave plates is connected to the concrete guardrail by means of planting bolts. The other end of the high-strength three-wave plates is connected to the three-wave corrugated beam guardrail or connected to the two-wave corrugated beam guardrail through a two-three transition plate. The strengthening columns are arranged on the back of the high-strength three-wave plates. The transition section friction beams are arranged below the high-strength three-wave plates and are bolted to the concrete guardrail and the strengthening columns. The transition section cross beams are connected to the concrete guardrail through connectors. The strengthening columns are spaced and anchored in the road surface.

[0008] Further, the cross beam of the transition section is composed of square tubes and connecting pieces welded together. Three rows of square tubes are arranged in the vertical height direction of the strengthening column. When the connecting piece is an integral connecting piece, one side of the cross beam of the transition section is bolted to the concrete guardrail by welding the integral connecting piece, and the other side is bolted to the strengthening column through the oblong holes provided in the square tubes; when the connecting piece is a split connecting piece, the cross beam of the transition section is bolted to the concrete guardrail through the split connecting piece.

[0009] Further, the friction beam of the transition section is formed by welding a welded steel pipe and a friction beam lapping plate. The friction beam of the transition section is provided with oblong holes and is bolted to the concrete guardrail and the strengthening column through bolts.

[0010] Further, the three-wave plate is provided with oblong holes and its top surface is inclined.

[0011] Further, the slope form of the impact-facing surface of the concrete guardrail is a single slope type, or an F type, or a strengthened type, or a New Jersey type.

[0012] Further, the cross-sectional shape of the strengthening column is a rectangular square column or a hollow cylinder, and the strengthening column can be anchored and connected to the road surface by means of pile driving, pile embedding, or flange plate.

[0013] Further, the impact-facing surface of the high-strength three-wave plate is flush with the impact-facing surface of the concrete guardrail.

[0014] After adopting the above technical solution, the utility model has the following beneficial effects:

[0015] (1) Through reasonable structural settings, the two ends are smoothly connected to meet the safety protection performance;

[0016] (2) The structure is simple, the construction is fast, the original guardrail does not need to be changed, and it is assembled on site and anchored by planting steel bars;

[0017] (3) The structure is connected to the bridge guardrail through anchor bolts and is smoothly connected to the corrugated beam. Only the corrugated guardrail can be seen on the impact-facing surface, and the landscape is consistent;

[0018] (4) Compared with the traditional structure, the amount of materials is greatly reduced, the construction personnel and equipment are saved, and the construction efficiency is improved;

[0019] (5) The construction period is short and the impact on road traffic is small. BRIEF DESCRIPTION OF THE DRAWINGS
