Abstract

The utility model provides a reinforced cement composite pile, which comprises a deep mixing pile body. The utility model is characterized in that a longitudinal framework is arranged in the pile body. The utility model can enhance the bearing capacity of the deep mixing pile 2 to 5 times; because the pile body can not generate compression deformation, any extrusion of underground facilities, such as surrounding buildings, pipe networks, etc. can not be generated in construction, the increase of the pore water pressure of foundation soil can be prevented, and the cost of unit load can be reduced 30 percent to 70 percent. Additionally, in the progress of the construction, the composite mixing pile has the advantages of no noise, no vibration, no pollution and no soil extrusion. The utility model in favor of environmental protection is a reinforced composite pile which is worth to be popularized and operated.

Description

The stiffened soil-cement composite pile

Technical field

The utility model relates to a kind of deep-mixed pile, belongs to building field.

Background technology

The various performances of ground are directly connected to the reliability and the safety of above ground structure, how to improve and improve the performance of ground, and crucial problem depends on the quality of the stake that son is driven underground.And the conventional deep-mixed pile that uses, its intensity is lower, and vertical ultimate bearing capacity generally between thousand Ns of 100-250, is easy to be damaged by pressure in underground generation distortion.Not only influence the reinforcing of ground, but also directly influence the safety of building, therefore, be necessary prior art is improved.

Summary of the invention

The purpose of this utility model is to overcome the deficiency of prior art, and provide a kind of and can effectively improve the agitation pile vertical bearing capacity, and easy construction, the stiffened soil-cement composite pile that cost is low.

The utility model is realized by following technical proposal: it comprises the deep-mixed pile pile body, it is characterized in that being provided with in the pile body vertical skeleton.The section of described vertical skeleton is one or more in cross or I-shaped or herringbone or T-shaped or the star.The section of described vertical skeleton also can be one or more in hollow, solid side's body or hollow, solid cylinder or hollow, solid triangle body or the hollow gengon, be used to improve the vertical bearing capacity of stake, simultaneously to underground building or pipeline etc. have no effect on every side.

The utility model compared with prior art has following advantage and effect: owing to be provided with vertical skeleton in stake; the bearing capacity 2-5 that can not only improve deep-mixed pile doubly; and because pile body does not produce compressive strain; in the construction underground installations such as surrounding buildings or pipe network are not produced any extruding; can not cause that the foundation soil pore water pressure raises; also can make the unit load cost reduce 30-70%; this compound agitation pile no dry sound in work progress in addition; friction; pollution-free; soil compaction not; very favourable to environmental protection, be a kind of reinforcement composite pile that is worthy of promotion and application therefore.
