Abstract
The utility model provides a highway weak soil layer stake composite foundation, highway weak soil layer stake composite foundation includes in the below of highway horizontal plane and along the horizontal a plurality of concrete pile body that sets up of highway extending direction, wherein a plurality of concrete pile lower extreme physically runs through the weak soil layer and the butt is in on the bearing layer of weak soil layer below, all stretch out the upper end of a plurality of concrete pile body the weak soil layer, wherein, serve as reasons and go up the toper of widen gradually down in the lower part of a plurality of concrete pile body, a plurality of concrete pile boards have been laid along highway extending direction, the concrete pile board is connected with the upper end of the horizontal a plurality of concrete pile body that sets up, still be provided with the mattress layer between concrete pile board and the weak soil layer. The utility model discloses a stake composite foundation has greatly reduced engineering cost and has shortened the time limit for a project, has strengthened factor of safety.
Description
Technical field
This utility model relates to expressway construction field, more particularly, to a kind of Freeway Soft layer pile composite foundation.
Background technology
In recent years, quick growth along with China's economy, the traffic flow of highway increases day by day, all oneself meets or exceeds saturation to the Freeway Transport ability of many two-way Four-Lane Roads, causes the raising of waste of time and cost of transportation, the pavement disease that the ratio that simultaneously occurs is more serious, service level and the service life of highway are had a strong impact on, therefore, requiring and improve Assessment of Serviceability of Roads for meeting the traffic of sharp increase, substantial amounts of two-way Four-Lane Road highway needs enlarging with newly-built.
In prior art, in the process of construction of highway, when running into Soft Soil Layer, it it is all form compound foundation by the way of intensive piling, meet the driving requirement of highway improving the bearing capacity of ground, this artificial and Material Cost is the most high, and the construction period is very long.
Utility model content
For the problems referred to above of the prior art, the utility model proposes a kind of Freeway Soft layer pile composite foundation significantly reducing construction costs and shortening the duration, structure of the present utility model greatly improves its safety coefficient and service life compared to existing technology.
The technical solution of the utility model is achieved in that
This utility model provides a kind of Freeway Soft layer, and described Freeway Soft layer pile composite foundation is included in the lower section of highway horizontal plane and along multiple concrete pile body of highway bearing of trend horizontally set,
Wherein, the lower end of the plurality of concrete pile body is run through Soft Soil Layer and is connected on the supporting course below described Soft Soil Layer, described Soft Soil Layer is all stretched out in the upper end of the plurality of concrete pile body, and wherein, the bottom of the plurality of concrete pile body is the taper the most gradually broadened；
Being laid with multiple concrete peg board along highway bearing of trend, described concrete peg board is connected with the upper end of multiple concrete pile body of horizontally set；
It is additionally provided with mattress layer between described concrete peg board and Soft Soil Layer.
Further, the spacing between bottom adjacent two concrete pile body is 10 to 30 centimetres.
Further, it is embedded with many longitudinal reinforcements in described concrete peg board.
Further, in described concrete-pile body, it is embedded with many vertical reinforcing bars, in described many vertical reinforcing bars all stretch into concrete peg board and is connected with longitudinal reinforcement.
Further, a diameter of 20-30 centimetre of the plurality of concrete pile body upper end.
This utility model passes through the design of the tapered concrete pile body in bottom, the contact area with Soft Soil Layer can be increased, therefore safety coefficient and service life are substantially increased, and very simple in Freeway Soft layer pile composite foundation practical operation of the present utility model, significantly reduce construction costs and shorten the duration.
