Below in conjunction with the accompanying drawing in the embodiment of the invention, the technical scheme in the embodiment of the invention is clearly and completely described, obviously, described embodiment only is the present invention's part embodiment, rather than whole embodiment.Based on the embodiment among the present invention, those of ordinary skills belong to the scope of protection of the invention not making the every other embodiment that is obtained under the creative work prerequisite.
Referring to Fig. 1, what wherein show is the schematic perspective view of the space enclosing structures such as diaphragm wall that constituted of a kind of U type concrete sheet-piling A according to a specific embodiment of the present invention, this sheet pile is made by concrete and is had the cross section that is substantially U-shaped (cross-sectional view can referring to Fig. 2-13), certainly, shown in Fig. 2-13, this shape of cross section also can be described as Chinese character " several " shape, described symbol only for convenience of description, concrete structure is described in detail with reference to Fig. 2-13.
In a specific embodiment of the present invention, the material that constitutes U type concrete sheet-piling A can be high performance concrete, RPC or fibrous concrete.What should emphasize is, what the present invention adopted is the sheet pile that concrete is made, and can not be equal to steel pile, because concrete has sizable difference with steel plate on mechanical strength and post-production, thus its structure that can adopt, shape just the present invention be different from one of difference that has steel pile now.For instance, because armor plate strength, pliability all are better than concrete greatly, therefore, the steel pile that adopts steel plate to make can be connected by the mode of mutual buckle, but adopting the shortcoming of steel plate maximum is that cost is too high, for reducing cost, steel plate can only be done more and more thinlyyer, but so therefore the side direction flexural strength of steel pile can reduce greatly; And if the cross sectional shape that adopts bending improves the flexural strength of side direction, increased the consumption of steel equally, processing cost also can uprise relatively.
At the above-mentioned defective of steel pile, the invention provides a kind of concrete sheet-piling of ad hoc structure form, its cross section can be referring to Fig. 2-13.
As shown in Figure 2, Fig. 2 shows is cross sectional representation according to a kind of U type concrete sheet-piling A of a specific embodiment of the present invention, wherein, described U-shaped cross-section has the bending segment 1 that is positioned at described U-shaped bottom, and first linkage section 2 and second linkage section 3 that are positioned at described U-shaped both sides, described first linkage section 2 and described second linkage section 3 have first connecting portion 21 and second connecting portion 31 that shape leans and cooperates respectively.Further, first linkage section 2 is outwardly open with the opening in second linkage section, 3 relative described U-shaped cross sections, form the bottom width of the A/F in described U-shaped cross section greater than described U-shaped cross section, the structure of this further qualification is to consider the convenience of concrete moulding, for example, after adopting mould molding, be convenient to the demoulding.
What Fig. 3 showed is first connecting portion 21 of U type concrete sheet-piling shown in Figure 2 and the enlarged diagram of second connecting portion 31, can know from figure and find out that first connecting portion 21 is substantially a groove shape, and second connecting portion 31 is substantially a convex.Certainly, it will be appreciated by those skilled in the art that first connecting portion 21 and second connecting portion 31 also can exchange mutually, that is, first connecting portion 21 is substantially convex, and second connecting portion 31 is substantially the groove shape.
Specifically, first connecting portion 21 and second connecting portion 31 lay respectively at the end of the opening 4 (referring to Fig. 2) in U-shaped cross section, first connecting portion 21 and second connecting portion 31 are the straightway that is formed at opening 4 ends in U-shaped cross section, this structure can be so that two location of adjacent sheet pile when connecting, because first connecting portion 21 and second connecting portion 31 all are straightways, therefore be convenient to control first connecting portion 21 of sheet pile both sides and the position of second connecting portion 31.Preferably, first connecting portion 21 and second connecting portion 31 are located along the same line, and extend to both sides along the opening 4 in described U-shaped cross section respectively.
First connecting portion, 21 middle parts have a groove 211, groove 211 both sides be the outstanding shoulder 212,212 of symmetry ', wherein, shoulder 212,212 ' be flat, and in the same plane.Groove 211 bottoms can be plane (shown in Fig. 3,4), also can be cambered surface (shown in Fig. 6,7), and still, shoulder 212,212 ' must guarantee it is flat will further specify this below.Corresponding to first connecting portion 21, second connecting portion, 31 middle parts have a projection 311 corresponding with above-mentioned groove 211, protruding 311 both sides be the shoulder 312,312 that sinks of symmetry ', wherein, shoulder 312,312 ' be flat, and in the same plane, wherein, shoulder 312,312 ' with above-mentioned shoulder 212,212 ' position on mutually corresponding.Projection 311 tops can be plane (shown in Fig. 3,4), also can be cambered surface (shown in Fig. 6,7), and still, shoulder 312,312 ' must guarantee it is flat will further specify this below.
As noted earlier, because sheet pile of the present invention employing is concrete, therefore, its structure can not adopt the form identical with steel pile.Consider that concrete corner intensity is little, the corner is damaged easily, if adopt the buckle mode to connect, in the process of piling, even if having slightly between two piles collide with or frictional force slightly big city the connecting portion of mutual buckle is damaged, be difficult to reach the effect of sealing.Therefore, in the present invention, a kind of specific connected mode against cooperation has been proposed, especially referring to Fig. 4 and Fig. 7, when two piles are interconnected to constitute pattern foundation pit supporting structure or space enclosing structure, wherein first connecting portion 21 of second connecting portion 31 of a pile (for example diagram left side) and adjacent another pile (for example illustrating the right side) is mutually against cooperating, but not is clasped.
When first connecting portion 21 and second connecting portion 31 mutually when cooperating, the projection 311 at second connecting portion, 31 middle parts is resisted against in the groove 211 at first connecting portion, 21 middle parts, makes the shoulder 212,212 of first connecting portion, 21 both sides ' be resisted against the respectively shoulder 312 of second connecting portion, 31 both sides simultaneously, 312 ' on, at this moment, because shoulder 212,212 ', 312,312 ' all is flat, and in the same plane, therefore can be by reach the effect of sealing against the mode that cooperates.Certainly, consider that concrete structure is difficult to reach very high precision, only depend on above-mentioned plane against still not enough, therefore, the present invention has further proposed other seal form.
Equally referring to Fig. 4,7, shoulder 212 in order to ensure first connecting portion, 21 both sides, 212 ' can be resisted against the shoulder 312 of second connecting portion, 31 both sides, 312 ' on, the shoulder 312 of projection 311 relative second connecting portions 31 at second connecting portion, 31 middle parts, 312 ' height h must be equal to or less than the shoulder 212,212 of groove 211 relative first connecting portions 21 at first connecting portion, 21 middle parts ' depth H.Same because the problem of the accuracy of manufacture, the height h that guarantees the projection 311 at second connecting portion, 31 middle parts is relatively easy things less than the depth H of the groove 211 at first connecting portion, 21 middle parts, therefore, when when first connecting portion 21 and second connecting portion 31 mutually when cooperating, first connecting portion 21 and second connecting portion, 31 shapes lean and will form a space 5 between the fitting face that cooperates, but watertight rubber bar or other encapsulants are starched or filled to concrete perfusion in the described space 5.
In according to a preferred embodiment of the present invention, described other encapsulants can be the pvc pipe (shown in Figure 11,12) of hollow, but the filler of concrete perfusion slurry and so in the described pvc pipe 6, comprise cement paste, mortar and other high fluidity waterproof and sealing materials etc., and the concrete grout of perfusion can be filled described space 5 by the aperture 61 that distributes on the described pvc pipe wall.This structure can prevent in the piling process, owing to causing space 5, reasons such as the sheet pile edge collides with have part to stop up, if do not adopt pvc pipe, form the cavity in the process that probably causes concrete perfusion to be starched, can't reach the effect of sealing, for example, when adopting concrete sheet-piling of the present invention as space enclosing structure, these cavities probably cause infiltration.
In addition, in each figure of the present invention, the corner angle part can be a circular shape so that eliminate stress concentrated.Shape can be dome shape (as Fig. 8, shown in 9,10) in the middle of it.
Figure 13-15 shows respectively is arrangement of reinforcement section according to the various U type concrete sheet-pilings of other specific embodiment of the present invention, as shown in the figure, vertically is distributed with many steel master muscle 7 along the U type concrete sheet-piling perpendicular to described U-shaped cross section.Described many main muscle 7 are each other by stirrup 8 colligations, and described stirrup can be netted colligation on the main muscle 7 or direct take-up strap on main muscle 7.
