Solidifying soil is fixed together.
Preferably, the prefabricated pile is concrete square pile, concrete circular pile or concrete tubular pile.
Preferably, the prefabricated pile is equipped with the bulb adjacent with pile crown, and bulb is located at pile crown hereinafter, described pre-
The diameter of through-hole is less than the diameter of bulb on cushion cap processed.
It preferably, is identical in pile crown prefabricated pile diameter below.
Preferably, the prefabricated pile is solid concrete stake, constitutes and is embedded with reinforcing bar, steel in the concrete of the prefabricated pile
Muscle beam or steel pipe, the reinforcing bar, tendon or steel pipe expose from the top of prefabricated pile and form the pile crown.
Preferably, shear key is additionally provided on the pile crown.
The invention solves another technical problem be to provide the construction method of above-mentioned connection structure.
This approach includes the following steps：
A, prefabricated pile is installed in place under water first；
B, prefabricated cushion cap is then lifted into prefabricated pile top, matches the through-hole on prefabricated cushion cap with pile crown, and
Toroidal cavity is formed between pile crown and through-hole wall；
C, by subaqueous concreting technique into the toroidal cavity between pile crown and through-hole wall concrete perfusion, will
Prefabricated pile and prefabricated cushion cap are connected and fixed.
Compared with prior art, the invention has the advantages that.
The present invention has carried out reasonable design to the structure of prefabricated pile and the underwater connecting node of prefabricated cushion cap, in prefabricated pile
Toroidal cavity is formed between pile crown and the through-hole wall of prefabricated cushion cap, and passes through the subaqueous concreting into the toroidal cavity
Mode is connected and fixed prefabricated pile and prefabricated cushion cap.This underwater connection type simple structure, easy for construction, low-cost, company
Reliable in quality is connect, and construction period can be greatly shortened, there is huge economic benefit and important realistic meaning.

Specific embodiment
Specific embodiments of the present invention will be described in further detail with reference to the accompanying drawing.These embodiments are only used for
Illustrate the present invention, and not limitation of the present invention.
In the description of the present invention, it should be noted that unless otherwise clearly defined and limited, term " installation ", " phase
Even ", " connection " shall be understood in a broad sense, for example, it may be being fixedly connected, may be a detachable connection, or be integrally connected；It can
To be mechanical connection, it is also possible to be electrically connected；It can be directly connected, can also can be indirectly connected through an intermediary
Connection inside two elements.For the ordinary skill in the art, above-mentioned term can be understood as the case may be
Concrete meaning in the present invention.
In addition, in the description of the present invention, unless otherwise indicated, the meaning of " plurality " is two or more.
As shown in Figure 1, being the first embodiment of the invention, the underwater connection structure packet of the prefabricated pile and prefabricated cushion cap
Prefabricated cushion cap 1 and Duo Gen prefabricated pile 2 are included, the top of prefabricated pile 2 has pile crown 21, and it is below pre- that the diameter of pile crown 21 is less than pile crown
The diameter of stake 2 processed, 2 diameter of prefabricated pile below of pile crown 21 is all identical.It is equipped on prefabricated cushion cap 1 and is connected with pile crown 21
Through-hole 11, the diameter of through-hole 11 is greater than the diameter of pile crown 21, but is less than pile crown 2 diameter of prefabricated pile below, therefore, prefabricated to hold
Platform 1 can be located in the top of prefabricated pile 2, and be formed between the pile crown of prefabricated pile 21 and the through-hole wall of prefabricated cushion cap 1
Toroidal cavity (as shown in Figure 4), by way of subaqueous concreting into the toroidal cavity concrete perfusion 3, make prefabricated
Cushion cap 1 and prefabricated pile 2 are fixed together.2 one side of prefabricated pile can play the role of the prefabricated cushion cap 1 of support, another party
Face can double as the bed die of subaqueous concreting.Above-mentioned prefabricated pile 2 can be concrete square pile, concrete circular pile or concrete
Tubular pole etc., for square pile, above-mentioned diameter should be understood as the circumscribed circle diameter of square-section.
As shown in Fig. 2, be second of embodiment of the invention, unlike the first embodiment, pile crown 21 with
Under the diameter of prefabricated pile 2 be not impartial.The bulb 22 adjacent with pile crown 21, bulb are equipped on prefabricated pile 2
22 be located at pile crown 21 hereinafter, and the diameter of bulb 22 be greater than the diameter at the other positions of prefabricated pile 2, and through-hole on prefabricated cushion cap
11 diameter is less than the diameter of bulb 22.In this way, bulb 22 can support prefabricated cushion cap 1, and double as underwater grouting coagulation
The bed die of soil., can be identical as the diameter of pile crown 21 as the diameter of the prefabricated pile 2 below of bulb 22, pile crown can also be compared
21 diameter is big.
In above-mentioned two embodiment, the partial structurtes such as shear key can also be increased, on pile crown 21 further to mention
The reliability that high prefabricated cushion cap 1 is bonded with pile crown 21.
As shown in figure 3, be the third embodiment of the invention, unlike above two embodiment, pile crown 21
It is not concrete structure.Prefabricated pile 2 is solid concrete stake, constitutes in the concrete of prefabricated pile 2 and is embedded with reinforcing bar, tendon
Or steel pipe 23, the reinforcing bar, tendon or steel pipe 23 expose from the concrete on 2 top of prefabricated pile, and form the pile crown 21.
That is, pile crown 21 is made of the reinforcing bar, tendon or steel pipe upwardly extended from concrete.Work as subaqueous concreting
After the completion of 3 constructions, these exposed reinforcing bar, tendon or steel pipes are just integrated in concrete, and by prefabricated cushion cap 1 and prefabricated pile
2 are linked together.
Above-mentioned connection structure can construct according to the following steps.
A, each prefabricated pile 2 is installed in place under water first；
B, then prefabricated cushion cap 1 is lifted into 2 top of prefabricated pile and is covered on pile crown 21, make through-hole on prefabricated cushion cap with
Pile crown 21 matches, and forms toroidal cavity between pile crown 21 and the inner wall of through-hole 11；
C, coagulation is perfused into the toroidal cavity between 11 inner wall of pile crown 21 and through-hole by subaqueous concreting technique
Prefabricated pile 2 and prefabricated cushion cap 1 are connected and fixed by soil.
The invention avoids traditional cofferdam construction methods, realize precast construction with mature subaqueous concreting technique
Underwater connection, simple structure, easy for construction, low-cost, quality of connection is reliable, there is huge economic benefit.
The above is only a preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, without departing from the technical principles of the invention, several improvement and replacement can also be made, these are improved and replacement
Also it should be regarded as protection scope of the present invention.
