The advantage of the invention is that：
(1) carbon fiber arrangement of reinforcement using synthetic resin as base-material, and is added auxiliary using carbon fiber as reinforcing material in the present invention
A kind of composite material that auxiliary agent is formed through pultrude process and surface treatment, its advantage is that it is corrosion-resistant, intensity is high, light-weight, as
The arrangement of reinforcement of support pile substantially increases the anti-crack ability of support pile.
The contact area that concrete support pile and soil layer are increased on the basis of reducing material is arranged in concrete support pile shape,
And the anti-crack ability of concrete support pile can be enhanced in the present invention using the setting of carbon fiber arrangement of reinforcement and position.
(2) since the top pile crown connection top Guan Liang of concrete support pile forms the foundation pit supporting system being closed, top pile crown
Carbon fiber reinforced concrete is used so that pile crown intensity is reinforced, conducive to whole stress.
(3) setting of the altitude range and mix ratio of carbon fiber reinforced concrete is after test of many times most in the present invention
Save the optimal result in the case of resource.
(4) outer edge of concrete support pile is smooth shape, makes so more convenient, is also prevented from corner's stress concentration.
(5) setting of reinforcement density can ensure the cracking resistance of concrete support pile in the case where saving resource in concrete support pile
Ability.
(6) arrangement of reinforcement in the present invention is replaced using carbon fiber arrangement of reinforcement and steel arrangement of reinforcement, can save carbon fiber arrangement of reinforcement in this way,
To cost-effective.
