This kind of installation is suitable for the completed bridge or strict requirements should not be carried out in the body of the abutment for any operation of the bridge, such as
This type of installation is suitable for complete bridges or bridges that strictly require that no operation should be carried out on the body of the abutment, such as railroad bridges. Outsourcing steel plate bottom appropriate to the abutment, on the unprotected parts of the bridge from the
For unprotected parts of the bridge from the abutment, distance is not economical.
Tie bolt hole fixing steel plate I-applicable to bridge construction is completed after the existence of pier template
Tie holes in the pier, and steel band (steel hoop) rely on fastening screws, fastening screws to take advantage of the original pier body template tensile holes, to avoid punching holes in other parts of the pier body.
Use the original pier body template trolley holes, to avoid punching holes in other parts of the pier body.
This installation method saves steel but affects the aesthetics of the bridge body, the steel belt is exposed, and later maintenance is more
Exposed, later maintenance is also more troublesome.
Pre-embedded steel plate
The inner surface of the pre-embedded steel plate is inserted into the steel cage of the abutment by planting reinforcement.
By pouring concrete to make it a whole, the outer surface of the steel plate and the surface of the abutment in a
The outer surface of the steel plate and the surface of the abutment are on a plane, not forming a bulge, which does not affect the aesthetic appearance of the abutment body. Later maintenance and replacement of fenders
and replacement of fenders are only carried out on the surface of the steel plate, and will not affect the structure of the abutment.
Fixed guarding facilities
Composite material anti-collision facilities have been successfully applied on many large bridges in China. In Anhui Province
In Anhui Province, the application cases are Maanshan Yangtze River Bridge, and Wuxuan Expressway Qingshuihe Bridge, which have stable performance, safe and reliable, with many advantages, mainly including
Stable performance, safety, and reliability, many advantages, mainly include: 1.
1. High efficiency of buffer energy absorption.
2. Strong corrosion resistance, durability, impact resistance, fatigue resistance, excellent performance, and small maintenance costs.
3. Lightweight, easy transportation, install, and replacement.
4. Self-floating, rotatable bow, minimizing damage to the ship.
5. Doesn't take up the net width of the waterway.
6. Beautiful modeling, green environmental protection, smooth and flat appearance.
7 non-metallic materials, anti-theft.
The main body of this collision avoidance facility is a water structure, and the construction process refers to the fiberglass/composite material boat specification.
The construction process refers to the specification of the fiberglass/composite material boat.
1. The corrosion resistance of the composite material should be by the national standard GB/T 3857 "Test Method for Chemical Resistance of Glass Fiber Reinforced Thermosetting Plastics".
Reinforced thermosetting plastics chemical media resistance test method".
2. The water absorption property of composite material shall conform to GB/T 14207-93 national standards "Test Method for Water Absorption of Interlayer Structure or Core".
The water absorption of composite material should be in accordance with GB/T 14207-93 National Standard "Test Method for Water Absorption of Sandwich Structure or Core" to ensure that the water absorption rate is less than 2%.
3. The color of the bumper is suggested to be orange-red (to be selected by the owner), and the outer surface should be coated with reflective paint.
Reflective paint should be applied.
Indicators of steel plate binder
The material of steel plate adhesive is according to the relevant provisions of Technical Specification for Reinforcement of Concrete Structures (CECS 25:90).
The binder used for reinforcement must have high bond strength, good durability, and a certain degree of rationality.
Good, with a certain rationality. Its strength index can be used in accordance with the following table.
