Abstract

The utility model discloses a fabricated water-permeating thin-wall tapered pile, which is characterized in that the fabricated water-permeating thin-wall tapered pile adopts the fabricated structure and consists of a pile cap, a pile body and a pile head. The pile body adopts tapered pipe bodies which are arranged in segments, and the adjacent tapered pipe bodies form joggling through tenon bodies nested into the tapered pipe bodies. Water permeating holes are arranged on the side walls of all segments of the tapered pipe bodies, and the pile head is connected with the bottom of the pile body. The front end of the pile head is a tapered tip, and the tail part of the pile head is joggled with the pile body through a convex pile head tenon. The pile cap is a platform fastened at the top part of the pile body. The fabricated water-permeating thin-wall tapered pile has generality and flexibility for various soft foundation soils, is beneficial to standardized manufacturing, has universality for the selection of pile-making machinery and tools, reduces the weight of the pile body, strengths the water draining and consolidation effects of weak soils, improves the combined action of the pile and the soils, can effectively improve the bearing capacity to the foundation, improves the controllability for the foundation settlement, shortens the construction period and lowers the engineering cost.

Description

The permeable thin-walled tapered pile of assembling

Technical field

The utility model relates to a kind of pile body structure, more specifically says so to be applied to build, all kinds of soft foundations in the highway, water conservancy, civil engineering, to reinforce and handle, improve bearing capacity of foundation soil fast, reduce the pile body structure of foundation settlement.

Background technology

In the construction of the civil engineerings such as structure of the construction of building, the build of highway subgrade, hydraulic engineering works, usually running into soft foundation handles and the reinforcing problem, adopt pile foundation form, to satisfy the requirement of structure, structure, building to bearing capacity of foundation soil and sedimentation.Existing all kinds of stake makes that owing to the dependence requirement to construction machinery the stake type is single relatively, the engineering time is long, engineering cost is high, and accommodation is limited, has the pile defective, is difficult to standardization and makes.Current main stake type such as castinplace pile and preformed pile, agitation pile etc.; Castinplace pile requires single-minded to boring machine, pile easily produces the hole of collapsing to pile body segregation, broken pile; Preformed pile to pile sinking machine power, length make, transportation is limited etc.; The agitation pile needs are mechanical specially, bearing capacity is limited.

The utility model content

The utility model is for avoiding above-mentioned existing in prior technology problem, provide a kind of assembling permeable thin-walled tapered pile, so that its application to all kinds of weak foundation soils has versatility and flexibility, being of value to standardization makes, selection for pile machinery and instrument has popularity, has the minimizing pile quality, strengthen the discharging consolidation effect of soft soil, improve the acting in conjunction of stake soil, and then improve supporting capacity, improve controllability, shorten the construction period and reduce engineering cost foundation settlement to ground.

The utility model technical solution problem adopts following technical scheme:

The design feature of the permeable thin-walled tapered pile of the utility model assembling is to adopt fabricated construction, is made up of pile cover, pile body and pile crown;

Described pile body is a conical tube, and described conical tube is the segmentation setting, and adjacent conical tube is to form joggle with the tenon body that is nested in the conical tube; The sidewall of described each section conical tube is provided with permeable hole;

Described pile crown is connected the bottom of pile body, and the front end of pile crown is the awl point, and the afterbody of pile crown is with the pile crown tenon and the pile body joggle of projection;

Described pile cover is one to snap onto the platform of pile body napex.

Compared with the prior art, the utility model beneficial effect is embodied in:

1, the utility model fabricated construction melts basis and stake in one, makes the design of basic engineering and single pile form integrated.

2, the utility model is platform with the pile cover, make the basis promptly under a pile cover, have many group pile bodies to be embedded in a single pile and even a clump of piles, the lotus platform is held in formation, the basis with acting in conjunction combine closely being strengthened of the rigidity of stressed carrying and drag and intensity.

3, the utility model pile body is the conical tube that segmentation is provided with, this makes piling construction method, the long selection of stake more flexible, make that stake changes of section form can be various, with existing single stake footpath and stake appearance ratio, the utility model can extensively adapt to the requirement of different treatment of soft ground and reinforcing; Greatly improve the discharging consolidation of the soil body between single pile bearing capacity, compaction pile, acceleration inter-pile soil; The standardization, finished productization, the seriation that are more conducive to the single pile design and make.

4, the joggle form of the embedded tubulose tenon of the utility model pile body body has been strengthened global configuration and anti-bending strength, make pile body integral body stressed, resistance characteristics is better.

5, the permeable form of the utility model pile body can be quickened the discharging consolidation of soft foundation, reduces the moisture of pile peripheral earth, improves the intensity of the soil body, and bearing capacity of single pile is greatly improved under the acting in conjunction of pile body and soil.

6, the hollow combination of the body cone-shaped body of the utility model king-pile has reduced pile quality, has reduced material consumption and expense, and the part supporting capacity also is provided simultaneously.

Description of drawings

Fig. 1 is the utility model structural representation.

Fig. 2 is the utility model decomposing schematic representation.

Number in the figure: 1 pile cover, 2 pile bodies, 2a permeable hole, 2b rigid connector, 3 pile crowns, 4 tenon bodies,

The specific embodiment

Referring to Fig. 1, Fig. 2, present embodiment adopts fabricated construction, is made up of pile cover 1, pile body 2 and pile crown 3;

Pile body 2 is a conical tube, and the conical tube segmentation is provided with, and adjacent conical tube is to form joggle with the tubulose tenon body 4 that is nested in the conical tube, and tenon body 4 can also can be solid for body; The sidewall of each section conical tube is provided with permeable hole 2a;

Pile crown 3 is connected the bottom of pile body, and the front end of pile crown 3 is the awl point, and the afterbody of pile crown 3 is with the pile crown tenon and the pile body joggle of projection;

Pile cover 1 is one to snap onto the platform of pile body napex.

In concrete the enforcement, each of pile body section conical tube can carry out selection and set each section wall thickness by different cone angle, different inner diameters, different length, the rigid connector 2b that each of combined pile body section conical tube should be provided for strengthening on upper surface and lower surface, such as with steel loop welding or prefabricated jointly, satisfy the requirement of strength of squeezing into, being pressed into of the construction technology of pile sinking.Each section conical tube is a hollow, axially perforation, inwall can be established circumferential reinforcement, to satisfy the requirement of strength of strengthening wall thickness.

Formation of pile can be to squeeze into or be pressed into pile crown and each conical section successively, and the loose tongue body connects pile cover on the top and promptly forms foundation platform, also can many group pile bodies can be set by clump of piles setting under a pile cover, forms a clump of piles.
