Control.
In order to achieve the above technical purposes, the utility model adopts the following technical solution: a kind of pile for prestressed pipe and steel pipe
Stake built pile supporting construction is alternately connected to become a built pile knot by least one steel-pipe pile and at least one pile for prestressed pipe
Structure, wherein the two of steel-pipe pile end face is welded with steel-pipe pile connection end respectively, and prefabricated pile for prestressed pipe also stays respectively at both ends
There is pile for prestressed pipe connection end, steel-pipe pile connection end and pile for prestressed pipe connection end bolt can be existed by connection bolt
Together.
Preferably, the steel-pipe pile connection end is identical with pile for prestressed pipe connection end structure, specific structure are as follows: whole
In lantern ring shape, as steel pipe grommet for being plugged into inside steel-pipe pile or pile for prestressed pipe, the other end is equipped with flange ring for one end,
Bolt hole is circumferentially formed on flange ring.
Preferably, the reinforcement structure being made of deep floor and circular reinforcing rib is connected on flange ring, wherein
Circular reinforcing rib is arranged concentrically with flange ring, using several deep floors it is equidistant be connected to vertically circular reinforcing rib with
Between flange ring.
Supporting construction provided by the utility model not only meets permanent, gib requirement, but also has following technology effect
Fruit: 1, pile for prestressed pipe and steel-pipe pile built pile support form belong to prefabricated assembled support form, than traditional supporting shape
Formula speed of application is fast, eliminates the curing time of concrete, the duration is greatly saved；2, pile for prestressed pipe and steel-pipe pile built pile
After support form is as gib, the steel-pipe pile of top half can be recycled, to reduce project cost.

Fig. 1 is the perspective view of the utility model supporting construction.
Fig. 2 is the plan view of the utility model supporting construction.
Fig. 3 is the perspective view of the utility model steel-pipe pile connection end or pile for prestressed pipe connection end.
Fig. 4 is the flat body figure of the utility model steel-pipe pile connection end or pile for prestressed pipe connection end.
Specific embodiment
With reference to the accompanying drawing, the utility model is described further.
A kind of pile for prestressed pipe as depicted in figs. 1 and 2 and steel-pipe pile built pile supporting construction, by 1 He of steel-pipe pile
One pile for prestressed pipe 4 is alternately connected to become a combination pilework, and wherein the two of steel-pipe pile 1 end face is welded with steel-pipe pile respectively
Connection end 2, prefabricated pile for prestressed pipe 4 are also respectively kept with pile for prestressed pipe connection end 3 at both ends, by connecting bolt 5
Steel-pipe pile connection end 2 and pile for prestressed pipe connection end 3 can be bolted together.
As shown in Figure 3 and Figure 4, the steel-pipe pile connection end 2 is identical with 3 structure of pile for prestressed pipe connection end, specifically
Structure are as follows: whole is in lantern ring shape, and one end is used to be plugged into inside steel-pipe pile 1 or pile for prestressed pipe 4 as steel pipe grommet 14, separately
One end is equipped with flange ring 11, is circumferentially formed with bolt hole 13 on flange ring 11.It is connected on flange ring 11 by deep floor
12 reinforcement structures constituted with circular reinforcing rib 15, wherein circular reinforcing rib 15 is arranged concentrically with flange ring 11, if using
Dry deep floor 12 is equidistant is connected between circular reinforcing rib 15 and flange ring 11 vertically.
The construction procedure of the utility model is as follows:
(1) firstly, 1 interface position of steel-pipe pile should carry out necessary derusting cleaning, welded steel pipe pile connecting pin after groove is beaten
First 2, it checks the quality of weld seam, guarantees the intensity requirement of connection；
(2) pile for prestressed pipe 4 will also install pile for prestressed pipe connection end 3 in prefabrication process, guarantee its installation
Firmness makes the two form an overall structure, and pile for prestressed pipe connection end 3 can be simultaneously as the anchor pad of presstressed reinforcing steel
Plate；
(3) when pile for prestressed pipe 4 is connect with steel-pipe pile 1, it is ensured that the firmness of connecting end surface, not due to sinking to construction
It causes to deform excessive, influences to remove.
Surveying setting-out work is carried out before formal construction according to the position of supporting construction, determines the point of each support pile,
It is in place to adjust drilling machine, after progress pilot hole pore-forming operation meets pile sinking requirement, is first inserted into pile for prestressed pipe 4 and meets the vertical of specification
Degree require, when sink to need pile extension when, according to Fig. 1 connection type carry out pile extension operation, it is ensured that connection it is sufficiently tight
Rear can proceed with pile sinking operation until reaching the supporting depth of design.It, can after constructing as temporary support structures
The bolt 5 of connecting node is unclamped, steel-pipe pile 1 can be recycled, project cost can be reduced.
A kind of pile for prestressed pipe and steel-pipe pile built pile supporting construction provided by the utility model, the built pile supporting knot
Structure type can have " pile for prestressed pipe+steel-pipe pile ", " steel-pipe pile+pile for prestressed pipe ", " steel-pipe pile+answer in advance to structure from bottom to top
Solenoid stake+steel-pipe pile " and " pile for prestressed pipe+steel-pipe pile+pile for prestressed pipe " etc., the built pile form of selection should be according to geology
Condition, soil layer situation, supporting depth, structure type in hole etc. are because usually considering.1 built pile of pile for prestressed pipe 4 and steel-pipe pile
Difficult point be connectivity problem between the two, in order to guarantee the simple of type of attachment, bolt of the proposed adoption similar to form of flanges
Connection type.
The pile for prestressed pipe 4 and 1 built pile support form of steel-pipe pile compare traditional campshed, ground-connecting-wall support form tool
There are short time limit, quality to be easy to many advantages such as guarantee, cheap；It, can be whole if upper part is using steel-pipe pile 1
It recycles and is used in turn, to reduce project cost.
Above embodiment is the preferred embodiment of the utility model, is not the implementation for limiting the utility model
