The method of bridge pier, belongs to field of civil engineering.
Background technique
In the stress system of bridge, main structure and main support object of the bridge pier as bridge are subjected to spanning knot
The whole load that structure transmits, but also directly bear a variety of loads such as pressure, water flow impact pressure, ship impact force.In load and
Under the action of external environment, it is easy to appear various diseases for bridge pier, such as the disengaging of bridge pier concrete surface, honeycomb, crack, dew muscle
Deng.The presence of these diseases greatly reduces the durability and stability of bridge pier, serious also to will cause collapsing for bridge, increases
The expenditure of economic cost influences the normal traffic trip of people, and there are biggish security risks.Bridge pier destruction will lead to bridge
The interruption of " lifeline ", will be inestimable to loss caused by economy and casualties, no matter for dilapidated bridge bearing capacity
It reinforces, the insufficient seismic hardening of shock resistance, the reinforcement and repair of the bridge pier still damaged, the bridge pier of armored concrete is reinforced
All there is important practical value and economic significance with recovery technique.
Common bridge pier consolidating method mainly includes Enlargement of Section, external prestressed strengthening method, steel sleeve method for strengthening etc.,
The respective advantage and characteristic of these methods is significant, plays the role of in practical applications and effect is also different.Increasing section
Method widely used technological means as tradition, work progress is relatively easy, but its steel bar meter, template construct with set up
It is time-consuming, and construction site workload is big, the construction period is long；Though external prestressing strengthening technology can effectively prevent the production in crack
It is raw, the force-bearing situation of bridge pier is promoted, but its construction technology is more complex；Major defect existing for steel sleeve reinforcement technique is that it needs to consume
Take more steel, steel pipe processing and assembly complexity, causes operating expenses higher, and be easy to appear the etching problem of material, shadow
Ring the service life of bridge.In addition, mechanical equipment required for traditional bridge pier consolidating method be easy by place around bridge pier,
The limitation of the conditions such as geology, traffic, inconvenience construction.
The flexible nets such as steel wire, fiber establishment net have many advantages, such as lightweight, corrosion-resistant, easily molded, high tenacity, relative to steel
Muscle, steel plate etc. have preferably molding convenience.Bamboo wood has excellent mechanical property, it is considered to be efficiency highest in nature
One of material, tensile strength reaches 140MPa or more, and the excellent mechanical property of bamboo wood is mainly derived from bamboo fibre, and bamboo is fine
Tie up the ratio of strength to weight with higher, fast growing, can natural degradation, cheap, bamboo wood is as structural material in building
Engineering field successful application, such as raw bamboo, Recombined bamboo, bamboo glulam.Using bamboo Composite Shell made of flexible net and bamboo fibre
The combinations of materials such as body are applied to the reinforcing of bridge pier, it is expected to play comprehensive benefit outstanding.
Summary of the invention
The object of the present invention is to provide a kind of methods of bamboo combined housing reinforced bridge pier, utilize flexible net combination bamboo Composite Shell
