Abstract
The utility model relates to a screwing-in type large bearing steel pipe pile and aims at providing the screwing-in type large bearing steel pipe pile which is simple in structure, convenient and quick to fabricate, high in production efficiency and convenient to construct so as to improve bearing force of pipe piles or reduce the number of piles to be piled and reduce vibration and noise generated in construction simultaneously. The technical scheme is that the screwing-in type large bearing steel pipe pile comprises a pipe-shaped pile body and is characterized in that spiral blades are coaxially arranged on the outer cylindrical surface of the pile body. The screwing-in type large bearing steel pipe pile is suitable for foundations of buildings.
Description
Technical field
The utility model relates to a kind of steel pipe pile, and the big carrying steel pipe pile of particularly a kind of screw-in is mainly as the building foundation.
Background technology
The load that is arranged on generations such as ground building and building structure is supported by ground usually.In case therefore the weight of structure surpasses the support force of ground; Will begin to occur the anomalies such as sinking of different shape; Sink to tilting to enlarge after after a while, structure becomes and can't continue to use, so when building the structure of constant weight; At first to make geological test, use foundation pile if the support force deficiency then need be strengthened support force in the place of building.For example need to strengthen support force and can use steel pipe system or concrete system pile body for building.Can adopt is driven underground pile body utilizes the method for the frictional force between pile body surface and the stratum, also can adopt the method for pile body being buried underground the stratum with required support force.The kind of used pile body is along with height, weight and the distance of building, and the degree of depth with support force stratum is different and change.The method of piling is generally adopted in the construction of foundation pile in the prior art, and this method can be accompanied by the fierceness vibration and the noise of ground.Therefore can make peripheral resident and constructor suffer from the influence of noise and vibration.
Summary of the invention
The technical problem that the utility model will solve is: to the problem of above-mentioned existence provide a kind of simple in structure, manufacturing is convenient, production efficiency is high, the big carrying steel pipe pile of the screw-in of easy construction; To increase the pile tube support force or to reduce piling number, the vibrations and the noise that produce when reducing to construct simultaneously.
The technical scheme that the utility model adopted is: the big carrying steel pipe pile of screw-in, comprise the tubulose pile body, and it is characterized in that: the coaxial spiral vane that is shaped on the external cylindrical surface of said pile body.
The hand of spiral of said blade is left-handed or dextrorotation.
Said blade is that integral body is processed or is spliced by plurality of sections.
Said blade arrangement is in pile body wherein on one section the external cylindrical surface or be arranged on the external cylindrical surface of whole pile body.
Adopt welding fixing between said pile body and the blade.
The beneficial effect of the utility model is: the utility model is the coaxial spiral vane that is shaped on the external cylindrical surface of pile body; The effective cross section of having strengthened the pile body front end is long-pending; Thereby obviously strengthened the load of pile body, made it can bear bigger down force in vertical direction; Because the existence of helical blade under the prerequisite of same load bearing requirements, has reduced the piling number, has accelerated construction speed; With regard to the steel pipe pile of same bearer power, it is underground that the draw of the utility model when construction helical blade capable of using is imbedded pile body, thereby required external force when having reduced construction has reduced the construction power consumption; Adopt screw-in during construction, the vibration and the noise that when job practicess such as hammering commonly used have reduced construction greatly, have produced have improved the working environment and the living environment of constructor and surrounding resident, more apparent modern civilized construction theory greatly.

The specific embodiment
Embodiment 1: like Fig. 1, shown in Figure 2, present embodiment comprises the tubulose pile body 1 that steel pipe is processed, and coaxial welding has spiral vane 2 (steel) on its external cylindrical surface.Blade 2 can be that directly integral solder also can be by being welded in pile body 1 surface after the plurality of sections splicing in pile body 1 surface behind the global formation in this example, and this blade arrangement is on the external cylindrical surface of whole pile body 1, and its hand of spiral is dextrorotation.
The manufacturing process of present embodiment is following: wherein the technological process of production of pile body 1 is: open flat-sanction plate-edging-pipe crimping-welding-full circle-aligning-flush-detection-packing warehouse-in etc.; Helical blade 2 adopts the continuous cold rolling mode to produce, the product size stable performance, and production efficiency is high; At last blade 2 is welded on the external cylindrical surface of pile body 1 and gets final product.
In practical application, excavate a little at first on the ground, this routine steel pipe pile is installed on the building machinery, stand on assigned position, apply revolving force and screw in.When being threaded to prescribed depth the second joint steel pipe pile is welded on the first segment steel pipe pile, notes during welding and should the helical blade 2 of two joint steel pipe piles be aligned mutually.Repeat above operation and reach the regulation requirement up to stake is dark, then the final section steel pipe pile is screwed into the head portion that makes steel pipe pile and exposes the face of land, promptly accomplish piling work at specified altitude.
With regard to as with regard to the steel pipe of foundation pile, if external diameter is bigger, when just burying underground, acting on resistance on the steel pipe part, can to draw the power of steel pipe than spiral part bigger, makes pile body be difficult in ground, bury underground swimmingly.Therefore the required external force of the utility model is less relatively, can select the motor of less power, more shows advantage energy-saving and cost-reducing today for vigorously advocating.
The said steel pipe pile of present embodiment not only can be used for bases such as building structure, middle high constructure, road markings, bridge, also can be widely used on all similar foundation piles.Its helical blade part especially has the effect of tangible increase bearing load for subgrade.
Embodiment 2: as shown in Figure 3, present embodiment structure and embodiment 1 are basic identical, and its difference only is that the hand of spiral of blade 2 is left-handed.
Embodiment 3: as shown in Figure 4, present embodiment structure and embodiment 2 are basic identical, and its difference is that blade 2 only is arranged in pile body 1 wherein on one section the external cylindrical surface, and promptly certain part of pile body 1 external cylindrical surface is welded with blade 2.
