Specific embodiment
The content of present invention is described in detail with embodiment with reference to the accompanying drawings of the specification:
Embodiment one:
As shown in figures 1-8:A kind of prefabricated assembled pipeline foundation, it include several spaced prefabricated piles 3 and
Cushion cap set on 3 top of prefabricated pile, the cushion cap include the pile cover 2 being connected with prefabricated pile 3 and set on adjacent pile covers 2
Support plate 1 between top;
Prefabricated pile is produced using building industrialization method, has production efficiency height, stable quality, relative inexpensiveness
Etc. advantages.Prefabricated pile with assembling cushion cap is combined and prefabricated assembled pipeline foundation is made by the present invention, not only sends out well
The speed advantage of prefabricated pile basement process is waved, and because cushion cap is split into pile cover 2 and support plate 1 so that each portion
Part is all unlikely to too big or too heavy, is readily transported and constructs.The prefabricated pile of the present invention can be round stake or square pile;Both
Can be hollow pile or solid pile.
The pile cover 2 is a cylinder, and the lower end of cylinder offers the blind hole 6 for being arranged prefabricated pile 3,2 top surface of pile cover
Equipped with fastening structure A;6 aperture of blind hole is slightly larger than 3 contour dimension of prefabricated pile so that docking action is more readily accomplished in construction;
Support plate 1 matches and snapping equipped with fastening structure B, fastening structure A and fastening structure B so that support plate 1 with
Pile cover 2 is connected as one.
The fastening structure A is the convex edge A2- extended along the longitudinal direction that 2 top surface arranged on left and right sides of pile cover is respectively equipped with
1, fastening structure B are the convex edge B1-3 extended along the longitudinal direction that 1 lower surface arranged on left and right sides of support plate is respectively equipped with.
The mutual snapping of the convex edge A2-1 and convex edge B1-3 can realize pile cover and the efficient combination of support plate.Convex edge
The cross section of A2-1 is trapezoidal, and trapezoidal convex edge A still can effectively ensure to support in the case where pipeline foundation has head fall
The correct connection of plate 1 and pile cover 2.Convex edge B1-3 can cause the width of support plate 1 to be more than the width of bolumn cap 2, realize more preferably
Economy.On the other hand the width on same 2 top surface of pile cover between the A2-1 of convex edge can be very good for adjusting pile cover, branch
The matching relationship of fagging, because during practical operation, prefabricated pile can all be deviated there are certain deviation such as prefabricated pile, and 2
The distance between a prefabricated pile will appear deviation, it is possible to when allowing to overlap between convex edge A2-1 and convex edge B1-3, convex edge A2-
There are gap between 1 and convex edge B1-3, for adjusting deviation.
The bar shaped limited block 1-1 extended in left-right direction is respectively equipped on the forward and backward side of 1 upper surface of support plate.
The setting of bar shaped limited block 1-1 so that the cross section of support plate 1 is " U "-shaped, convenient for the limiting to pipeline, prevents pipeline lateral
Displacement.Bar shaped limited block 1-1 can improve the rigidity and bearing capacity of support plate simultaneously, realize more preferably economy.
The cushion cap further includes the closing filler 4 of the seam crossing between adjacent shore plates 1, closing filler here
4 be concrete.On the one hand the setting for closing filler 4 may be such that support plate, pile cover are combined into entirety, form cushion cap, improve
Integral strength;The dimensional discrepancy generated in work progress can be adjusted simultaneously.
The upper surface of the support plate 1 and pile cover 2 is equipped with hanging ring 5.The setting plate easy to support of hanging ring and the fortune of pile cover
Defeated, lifting and installation.
The pile cover 2 is made of armored concrete, framework of steel reinforcement A2-2 is equipped in pile cover 2, for improving the punching of pile cover 2
Bearing capacity.
The support plate 1 is made of armored concrete, and framework of steel reinforcement B is equipped in support plate 1.
Embodiment two:The structure of the embodiment of the present invention two is substantially similar to the structure of embodiment one, and the main distinction is
The difference of fastening structure A, fastening structure B structure, as shown in Figure 9:The fastening structure A is pile cover 2 top surface arranged on left and right sides point
The groove A2-3 extended along the longitudinal direction not opened up, fastening structure B are what 1 lower surface arranged on left and right sides of support plate was respectively equipped with
The convex edge C1-5 to match with groove A2-3.
The width of groove A2-3 is more than the width of convex edge C1-5 so that convex edge C1-5 is empty there are one adjusting in groove A2-3
Between, similar with the relationship of convex edge B1-3 with one convex edge A2-1 of embodiment, such design can be very good for adjusting pile cover, branch
The matching relationship of fagging.But adjusting spaces of the convex edge C1-5 in groove A2-3 be more for embodiment one for embodiment two
Small, more limited, it is advantageous to fastening structure A, the fastening structure B shown in embodiment one.
Embodiment three:The structure of the embodiment of the present invention three is substantially similar to the structure of embodiment one, two, and the main distinction exists
In the difference of fastening structure A, fastening structure B structure, as shown in Figure 10:The fastening structure A is 2 top surface of pile cover left and right two
The convex edge D2-4 that side was respectively equipped with extend along the longitudinal direction, fastening structure B are set respectively for 1 lower surface arranged on left and right sides of support plate
The groove B1-5 that some matches with convex edge D2-4.
Here groove B1-5 width can be more than convex edge D2-4 width so that convex edge D2-4 in groove B1-5 there are one
Adjust space can to avoid prefabricated pile there are certain deviation in the case of, groove B1-5 can be embedded in the D2-4 of convex edge.But
The adjusting space smallers of convex edge D2-4 in groove B1-5 for embodiment one of embodiment three, it is more limited, it is advantageous to
Fastening structure A, fastening structure B shown in embodiment one.
Example IV:The assembly method of prefabricated assembled pipeline foundation of the present invention, it includes the following steps:
A. several intervals of prefabricated pile 3 are squeezed into soil;
B. connecting material is coated on the internal face of 2 blind hole of pile cover, pile cover 2 is then sleeved on prefabricated pile 3 from top to bottom
On top surface;In the fitting interface applying joint material of blind hole 6 and prefabricated pile 3 prefabricated pile 3 is fitted closely with pile cover.It waits to connect
After material hardening, you can completion pile cover 2 is reliably connected with prefabricated pile 3.
C. connecting material is coated on the top surface of pile cover 2, support plate 1 is placed in from up to down on the top surface of adjacent pile cover 2,
The fastening structure B of 1 one end of support plate is placed on 2 top surface of a pile cover, and the fastening structure B of 1 other end of support plate is placed in adjacent pile cover 2
Top surface on, and two fastening structure B are connect respectively with the mutual snappings of fastening structure A between two fastening structure B;
