The specific embodiment
Below in conjunction with accompanying drawing and embodiment, the specific embodiment of the utility model is described in further detail.Following examples are used to explain the utility model, but are not used for limiting the scope of the utility model.
Like Fig. 1, Fig. 2 and shown in Figure 3, a kind of interlock stake drum type basis of the utility model embodiment comprises: plain concrete pile 1, reinforced concrete pile 2 and cushion cap 3.
As shown in Figure 5, the construction method on the interlock stake drum type basis of the utility model includes following steps:
Step S1; Build according to interlock stake drum type Base Design shape and to lead wall, particularly: lead wall chase along phase embedding drum type basic engineering circumferential position excavation, and be cast in to lead to form in the wall chase with steel concrete and lead wall; Lead the wall degree of depth generally at 1.2m~2.0m; The bottom is dropped on the former soil layer, leads the wall metope and is higher than construction plant 10m~20cm, and the effect of leading wall is that the position that limits plain concrete pile 1 and reinforced concrete pile 2 also provides support for pile machinery;
Step S2 carries out the excavation in plain concrete pile hole: put into sleeve pipe within the walls and use all casing drill to fetch earth at sleeve pipe leading, when fetching earth, press down sleeve pipe, formin concrete pile hole;
Step S3, treat that per two plain concrete pile holes are dug after, in the plain concrete pile hole perfusion ultra retarded concrete;
Step S4 before the ultra retarded concrete initial set of plain concrete pile 1, carries out the excavation in reinforced concrete pile hole between per two plain concrete piles;
Step S5, treat that the reinforced concrete pile hole is dug after, put into reinforcing cage and carry out concrete casting;
Step S6, repeating step S2-S5 carry out the construction of reinforced concrete pile 2 and plain concrete pile 1, and be as shown in Figure 4; The construction sequence of plain concrete pile 1 and reinforced concrete pile 2 is: doing the stake of I type earlier is plain concrete pile 1; After the stake of two I types, doing the stake of II type again is reinforced concrete pile 2 before and after accomplishing, and concrete sequence of construction is I1 → I2 → II1 → I3 → II2 → I4 → II3......I; The stake of II type is spaced apart, forms circulus after construction is accomplished.When constructing at last, the concrete of first plain concrete pile 1 solidifies when building last root reinforced concrete pile 2, and interlock fully possibly influence the globality of mechanism, several kinds of technologies below can adopting this moment:
1, two reinforced concrete piles 2 that increase are positioned at the both sides of last reinforced concrete pile 2 and first plain concrete pile 1 intersection, and with last root reinforced concrete pile 2 embedding mutually.
2, first pile is made sand pile, treat that last root reinforced concrete pile 2 is accomplished after, dig out sand and placing of concrete.
3, add steel sleeve in first pile, treat that last root reinforced concrete pile 2 is accomplished after, penetration concrete in steel sleeve.
Step S7 builds cushion cap 3 on the circulus that reinforced concrete pile 2 and plain concrete pile 1 form, accomplish the construction on interlock stake drum type basis.
Can find out by above embodiment; The utility model embodiment bears the horizontal confined pressure that the suffered load in basis is distributed to surrounding soil through adopting interlock stake drum type basis; Have bigger bending resistance, effectively utilized the restraint forces of soil layer, guarantee that the basis can bear the huge bending moment that is transmitted by tall and slender structure; Have better support effect and bending resistance effect, compare with traditional basis and can save a certain amount of reinforcing bar and concrete.
The above only is the preferred implementation of the utility model; Should be understood that; For those skilled in the art; Under the prerequisite that does not break away from the utility model know-why, can also make some improvement and modification, these improvement and modification also should be regarded as the protection domain of the utility model.
