Description
Technical Field
The utility model relates to a excavation supporting field, a plastics cement strength core specifically says so, this plastics cement strength core is applicable to the ground work progress, has at soil layer and loose sand bed and is showing technical and economic advantage.
Background
The foundation pit is located in a shallow foundation pit in a soil layer and loose sand layer area, a steel pipe pile is usually adopted as a support pile, but the economical ratio of the steel pipe pile is poor under the condition that the steel pipe pile cannot be recycled due to limited site conditions and peripheral environmental factors; if adopt the utility model discloses replace the steel-pipe pile, then in the aspect of mechanical properties, economic index, the utility model discloses all be superior to the steel-pipe pile.
The bolt typically employs a spin-on-hole process, but requires casing follow-up in unconsolidated formations to prevent collapse of the hole. The casing process is labor-time consuming and high in cost; if adopt the utility model discloses replace, then can easily solve the hole problem of collapsing, can form pulling force type or pressure type anchor rope simultaneously.
For the foundation, for soft soil areas, foundation treatment is usually performed by adopting cement soil mixing piles, discrete piles and the like, but the strength of the treated foundation soil is usually limited by the strength of a pile body; if CFG piles are used for foundation treatment, the cost is too high. The utility model discloses low price just has stronger pile body intensity, can solve above problem.
The utility model discloses possess good axial atress performance, can be used for the anti project of floating of basis reinforcement, building.
Disclosure of Invention
The utility model aims at providing a plastics cement strength core, the utility model discloses in soil layer and loose sand bed, through guide arm hammering steel awl point, can drive thin wall steel pipe, the same entering ground body of plastics french drain pipe, then the dowel steel, can form the higher strength core of intensity after treating the steel pipe inside and outside slip casting, possess better tensile, resistance to compression, shear, bending resistance.
In order to solve the problems in the prior art, the technical scheme is as follows:
a plastic cement strength core body comprises a thin-wall steel pipe, a plastic blind ditch pipe, a circular steel base plate, a steel cone tip and reinforcing steel bars; the outer side of the thin-wall steel pipe is sleeved with a plastic blind groove pipe, the front end of the thin-wall steel pipe is welded with a circular steel base plate, and a steel cone tip is arranged on the circular steel base plate; and the inner wall of the thin-wall steel pipe is provided with a steel bar or steel strand support.
The round steel base plate is internally provided with a reinforced steel base plate for bearing the impact of the steel guide rod.
Compared with the prior art, the utility model has the advantages that:
1. the utility model discloses pore-forming in soil layer and loose sand bed can avoid the hole of collapsing.
2. The utility model discloses possess good mechanical properties.
3. The utility model discloses possess nimble changeable size parameter, make things convenient for the field control.
4. The utility model discloses possess wide application prospect, can be used to among the rock-soil related engineering such as foundation ditch fender pile, ground anchor body, ground processing, foundation engineering.

Detailed Description
In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the orientation words such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" etc. are usually based on the orientation or positional relationship shown in the drawings, and are only for convenience of description and simplification of description, and in the case of not making a contrary explanation, these orientation words do not indicate and imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore, should not be interpreted as limiting the scope of the present invention; the terms "inner and outer" refer to the inner and outer relative to the profile of the respective component itself.
The present invention is described in further detail below with reference to the accompanying figures 1-2 of the specification.
A plastic cement strength core body comprises a thin-wall steel pipe 1, a plastic blind ditch pipe 2, a round steel base plate 3, a steel cone tip 4 and a steel bar 6; the outer side of the thin-wall steel pipe 1 is sleeved with a plastic blind groove pipe 2, the front end of the thin-wall steel pipe 1 is welded with a circular steel backing plate 3, and a steel cone tip 4 is arranged on the circular steel backing plate 3; and the inner wall of the thin-wall steel pipe 1 is provided with a steel bar 6 or a steel strand support.
A reinforced steel backing plate 5 is arranged in the circular steel backing plate 3 and used for bearing the impact of the steel guide rod.
The steel cone 4 is triangular. The steel cone tip 4 is conical.
The pipe body of the thin-wall steel pipe is provided with a plastic blind ditch pipe which is sleeved outside the flower hole. Cement mortar is injected into the interior and exterior of the thin-wall steel pipe.
And a steel guide rod penetrates into the thin-wall steel pipe, the steel conical tip 4 is hammered through the steel guide rod, then the thin-wall steel pipe and the plastic blind ditch pipe are driven to enter the rock-soil body together, the steel bars are inserted, mortar is poured, and a powerful core body with higher strength is formed after the mortar inside and outside the steel pipe is solidified.
The above, only be the concrete implementation of the preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art is in the technical scope of the present invention, according to the technical solution of the present invention and the utility model, the concept of which is equivalent to replace or change, should be covered within the protection scope of the present invention.
