Abstract

The utility model discloses a kind of prose style free from parallelism grouting behind shaft or drift lining strength core composite pile, it is characterized in that: comprise first, first is bulk solid stake, is sand, rubble, cobble, gangue, slag, broken concrete block, slag, brickbat watt or mixture; In first, arrange core stake, core stake is cast-in-place plain concrete pile, cast-in-situ steel reinforced concrete stake or preformed pile; Certain distance is had bottom the discrete plastochondria stake in core stake bottom; Establish in core stake and carry out grouting behind shaft or drift lining Grouting Pipe and injected hole.The utility model is rational in infrastructure, easy construction, only needs to carry out grouting operation by Grouting Pipe and injected hole to peripheral pile.Peripheral granular pile/cement earth pile can play eliminates liquefaction, the effect of consolidation draining.

Description

Prose style free from parallelism grouting behind shaft or drift lining strength core composite pile
Technical field
The utility model relates to a kind of composite pile.
Background technology
Existing pile body, is generally common composite pile or monomer stake form, carry out grouting behind shaft or drift lining construction and extremely bother, and effect is bad in the soil properties such as clay to stake; The side frictional resistance running into common stake during liquefaction soil layers is difficult to play a role; The soil compaction effect of common stake easily causes the phenomenons such as neighboring buildings destruction, upfloat.These problems are difficult problems that this area is thirsted for solving for a long time.
Summary of the invention
The purpose of this utility model is to provide a kind of rational in infrastructure, can realize the prose style free from parallelism grouting behind shaft or drift lining strength core composite pile of grouting behind shaft or drift lining operation.
Technical solution of the present utility model is:
A kind of prose style free from parallelism grouting behind shaft or drift lining strength core composite pile, it is characterized in that: comprise first, first is bulk solid stake, is sand, rubble, cobble, gangue, slag, broken concrete block, slag, brickbat watt or mixture; In first, arrange core stake, core stake is cast-in-place plain concrete pile, cast-in-situ steel reinforced concrete stake or preformed pile; Certain distance is had bottom the discrete plastochondria stake in core stake bottom; Establish in core stake and carry out grouting behind shaft or drift lining Grouting Pipe and injected hole.
First bottom adds one section of cast-in-place plain concrete, when core stake is squeezed into, forms enlarged footing at this interface.
The distance in two times of stake footpaths is had bottom the discrete plastochondria stake in described core stake bottom.
In first, pile tube is set, have certain distance bottom the discrete plastochondria stake in pile tube bottom, the bottom of pile tube arranges the hush panel sealed by bottom opening, and hush panel offers injected hole, Grouting Pipe in grouting port fills with pipe is connected, and the bottom of grouting port arranges clapper.
The utility model is rational in infrastructure, easy construction, only needs to carry out grouting operation by Grouting Pipe, injected hole to peripheral pile.Peripheral granular pile/cement earth pile can play eliminates liquefaction, the effect of consolidation draining.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is described in further detail.
Fig. 1 is the structural representation of the utility model embodiment 1.
Fig. 2 is the structural representation of embodiment 2.
Detailed description of the invention
Embodiment 1:
A kind of prose style free from parallelism grouting behind shaft or drift lining strength core composite pile, comprises first 1, and first is bulk solid stake (for sand, rubble, cobble, gangue, slag, broken concrete block, slag, brickbat watt or mixture), and first bottom can add one section of cast-in-place plain concrete 2; In first, arrange the stake of core stake 3(core is cast-in-place plain concrete pile, cast-in-situ steel reinforced concrete stake or preformed pile), there is certain distance bottom the discrete plastochondria stake of described core stake bottom.Grouting Pipe and injected hole 4 is established in core stake; After grouting behind shaft or drift lining, peripheral pile becomes cement earth pile; Enlarged footing 5 can be formed on first bottom.
Embodiment 2:
A kind of prose style free from parallelism grouting behind shaft or drift lining strength core composite pile, certain distance is had bottom the discrete plastochondria stake in pile tube bottom, comprise first 11, first is bulk solid stake, in first, arrange pile tube 12, the bottom of pile tube arranges the hush panel 13 sealed by bottom opening, hush panel offers injected hole 14, Grouting Pipe 15 in grouting port fills with pipe is connected, and the bottom of grouting port arranges clapper 16.
