Abstract
The utility model discloses a prefabricated reinforced concrete square pile which comprises an upper segment pile and a lower segment pile and further comprises a first injection pipe and a second injection pipe. The first injection pipe is placed on the center of the upper segment pile, the second injection pipe is placed on the center of the lower segment pile, the first injection pipe communicate the upper segment pile, and the second injection pipe communicate the lower segment pile. The upper end of the lower segment pile is connected with the lower end of the upper segment pile, the lower end of the lower segment pile is provided with a pile point which is provided with an injection hole, and the second injection pipe is communicated with the injection hole. Compared with the background art, the prefabricated reinforced concrete square pile not only can improve the bearing capacity of a single pile and save costs, but also can overcome the shortages of large construction noise, low efficiency and serious environmental pollution and the like when a pile is poured by a drill hole.
Description
Technical field
The utility model relates to a kind of Prefabricated Reinforced Concrete Square Pile.
Background technology
Continuous propelling along with China's urban development construction process, gradually reducing of the idle land area in urban district, cause building longitudinally short transverse significantly improve, plane figure is significantly compressed, in the urban district between adjacent building the distance constantly reduce, Design of Foundation and the construction of building are had higher requirement.
East China-Shanghai, Jiangsu, zhejiang and other places Pile Foundations Design adopt more pile foundation type that bored pile, prestressed concrete pipe pile and Prefabricated Reinforced Concrete Square Pile are arranged at present.It is high that bored pile has a bearing capacity of single pile, on the less characteristics of surrounding enviroment impact, the shortcomings such as but it is various to have simultaneously the construction technology link, and efficiency of construction is low, long in time limit, the mechanical execution noise is large, the problems such as mud drilling construction and discharging are also very serious to the pollution of environment.Prestressed concrete pipe pile and Prefabricated Reinforced Concrete Square Pile, technological characteristics of construction are that mechanical execution efficient is higher, and the job site civilized construction is effective, adopt the static pressure construction pollution from environmental noise less.But it is that bearing capacity of single pile is low that these two kinds of techniques have common shortcoming, and the soil extrusion in construction effect is larger, must take into full account the protection to peripheral path pipeline and Nearby Structure during construction.These two kinds of stake types are compared, and prestressed concrete pipe pile Under Lateral Loading ability is very low, the shearing resistance weak effect, and precast square pile also can bear the part horizontal loading simultaneously except bearing vertical load, the soil compaction effect pile tube is more a shade better again than square pile.Several techniques respectively have quality.
Therefore, need a kind of new pile body to address the above problem.
The utility model content
The purpose of this utility model is for problems of the prior art, and a kind of raising bearing capacity of single pile is provided, and saves the Prefabricated Reinforced Concrete Square Pile of cost to address the above problem.
For realizing above-mentioned utility model purpose, Prefabricated Reinforced Concrete Square Pile of the present utility model can adopt following technical scheme:
A kind of Prefabricated Reinforced Concrete Square Pile, comprise joint stake and the stake of lower joint, also comprise the first Grouting Pipe and the second Grouting Pipe, described the first Grouting Pipe is positioned at the center of described upper joint stake, described the second Grouting Pipe is positioned at the center of described lower joint stake, described the first Grouting Pipe connects described upper joint stake, and described the second Grouting Pipe connects described lower joint stake; The upper end of described lower joint stake is connected with the lower end of described upper joint stake, and the lower end of described lower joint stake has pile top, and described pile top is provided with injected hole, and described the second Grouting Pipe is communicated with described injected hole.
Beneficial effect: compare with background technology, Prefabricated Reinforced Concrete Square Pile of the present utility model can either improve bearing capacity of single pile, saves cost, can remedy the deficiencies such as the bored pile construction noise is large, efficient is low, environment pollution is serious again.
