Abstract
The utility model relates to a steel pile tube with a closed conical end. The object of the utility model is to provide a steel pile tube with a closed conical end, which is simple in structure, and easy and rapid for manufacturing. The steel pile tube can rapidly penetrate a hard soil layer or can be effectively hammered into a hard soil layer to increase supporting force and increase the bearing capacity of a pile tube body. Moreover, the objects of the utility model also include reducing the number of steel pile tubes, saving steel and lowing construction cost. The steel pile tube with a closed conical end comprises a pile tube body and pile tube head and is characterized in that the pile tube body is a circular steel pipe, the pile tube head is an integrally structure which is made by welding together a conical hollow cover, reinforcing ribs and central pillars, and the peripheral cylindrical portion of the conical hollow cover is welded together with the pile tube body. The steel pile tube can be used as a temporary pile in building construction.
Description
Technical field
The utility model relates to a kind of steel pipe pile, especially a kind of closed cone-shaped end steel pipe pile.Be applicable to the provisional pile foundation of using in the engineering construction.
Background technology
In recent years, along with the rapid development various places of the economy dynamics of investment to infrastructure construction strengthens, object of construction production is also more and more.In many Engineering Project Construction, owing to receive the restriction of execution conditions or duration, just seem extremely important as the temporary works trestle of auxiliary construction.For example, Ningbo Construction of Hangzhou Bay Cross-sea Bridge south bank construction bridge, 9444 meters of total lengths 633 are striden totally, are unique passages that marine main bridge construction material supply and traffic are come in and gone out, and also are the basic engineering and the controlled engineerings of bed rearrangement bridge spanning the sea construction.
Temporary steel pipe pile foundation or prestressed concrete steel pipe stake can be adopted at present interim trestle basis, and steel pipe pile is compared with prestressed concrete pile, and steel pipe pile has the intensity height; Rigidity is big, and the discreteness of material is little, and extensibility is high; Shock-resistant, piling injection performance is good, adapts to characteristics such as all kinds of soil properties.Steel pipe pile can penetrate hardpan or squeeze into hardpan effectively, obtains higher bearing capacity, helps the settlement Control of temporary structure engineering; And can bear bigger horizontal force; Flexible design, also can vertically, laterally put down to join through welding increases resistance to overturning, thereby is used widely.But because the steel tube surface smoother can descend its bearing capacity to some extent, can influence workmanship when serious, jeopardize construction safety, just become extremely important so improve the steel pipe pile bearing capacity.
Summary of the invention
The technical problem that the utility model will solve is: according to the problem of above-mentioned existence; A kind of simple in structure, convenient for production, closed efficiently cone-shaped end steel pipe pile of manufacturing is provided; Can penetrate hardpan or squeeze into hardpan effectively and increase support force; Improve pile body bearing capacity, reduce piling quantity, practice thrift steel and reduce construction cost.
The technical scheme that the utility model adopted is: closed cone-shaped end steel pipe pile; Comprise body and pile crown; It is characterized in that: said body is a round steel pipe; Pile crown is welded into overall structure by hollow taper skull, deep floor and intermediolateral column, and wherein the outer rim circle ring column portion and the body of taper skull are welded.
Said deep floor is triangular in shape, and quantity is 3 ~ 4 and is uniformly distributed with.
Said intermediolateral column is hollow circular-tube or solid cylinder.
Said taper skull forms smooth outer surface by the whole spinning of an iron plate.
The beneficial effect of the utility model is: the sealing pyramidal structure is adopted in the utility model steel pipe pile termination, and the termination sealing has bigger contact area than the open-type stake at tip position and soil, significantly promotes bearing capacity; Seal because of its termination, in construction, increased soil compaction effect, the compactness shear strength of the soil body increases, thereby the side skin friction of stake is increased greatly, and the bearing capacity of stake improves, and can reduce the piling number.The design of taper reduces pile body construction resistance, meets hardpan and also more is prone to penetrate, and construction speed is accelerated.The utility model is manufactured convenient and swift, and production efficiency is high, can effectively practice thrift steel in the use, reduces construction cost.
Description of drawings
Fig. 1 is the sectional drawing of the utility model.
Fig. 2 is the stereogram of the utility model pile crown.
Fig. 3 is the vertical view of the utility model.
The specific embodiment
Like Fig. 1, shown in Figure 2, present embodiment is a kind of closed cone-shaped end steel pipe pile, and its body 1 is formed with pile crown 2 two parts, and pile crown is connected an end (see figure 1) of body.Body is a round steel pipe, and described pile crown comprises deep floor 3, intermediolateral column 4 and taper skull 5, and the taper skull is the integral body that whole block material is processed, and does not have to connect seam, and the lower end is shaped as taper shape, and the upper end is provided with one section straight flange that matches with body; Intermediolateral column is arranged on the center of taper skull, it can be hollow also can be solid; Deep floor can be 3 or 4, is uniformly distributed in the taper skull, is connected (seeing Fig. 2, Fig. 3) with the taper skull with intermediolateral column.
Described reinforcing rib is a thick iron plate, but the cold punching mode is produced dimensionally stable, production efficiency height; But also simple machine after the blanking.Intermediolateral column can with after round steel or the direct blanking of seamless steel pipe again with end face a little the worker polish and get final product, production process is simple, efficient is high, and does not have waste material and produce.The taper skull is the integral body that whole block material is processed, and can adopt spin-on process processing, and its equipment and mold is all fairly simple, does not need too many input, can produce with lower cost, and the product quality performance is all stablized.
At first confirm the convenient lifting of putting position of steel pipe pile during construction according to order about the use successively of steel pipe pile, steel pipe pile adopts outstanding play construction, with pedrail crane vibrating hammer injection steel pipe pile.Utilize the cantilever guiding trestle accurately to squeeze into basic steel pipe pile, after definite verticality with stake of measurement group meets the demands, start vibrating hammer and sink to putting in place, weld next joint more on request, the continuation sinking construction is so repeatedly to the designing requirement degree of depth.Single pile is heavy to be put after construction finishes, and immediately it is put with heavy that the steel pipe pile that finishes is flat to be joined construction and be linked to be integral body, prevents that single pile from deflection taking place under flow action.After stake top laid distribution beam, Bei Leiliang and bridge floor, the crawler crane reach was inserted and is laid one and stride steel pipe pile, according to said method, constructs by easy stages.
