It is：Pile top is installed with the bottom of the steel-pipe pile, on the side wall of the steel-pipe pile some sand outlets are offered, if
Do the sand outlet to be evenly arranged on the side wall of the steel-pipe pile.
The pile top is connected and composed by back cover steel plate and H profile steel, wherein the H profile steel is weldingly fixed on the back cover steel plate
Bottom surface, the top surface of the back cover steel plate is weldingly fixed on the bottom of the steel-pipe pile seals the bottom of the steel-pipe pile.
Angle bar hangnail is welded with the outside of the sand outlet, the angle bar hangnail is towards on the outside of the steel-pipe pile
Side.
The utility model has the advantages that：The end resistance and side friction when being pressed in sand, silty soil can be reduced；Heavy
Grittiness soil compactness on the outside of sand outlet is reduced during stake, sandy soil is easily flowed into inside steel-pipe pile, while preventing pile sinking mistake
Sand outlet blocking in journey；It is simple and reasonable, it is easy to process, it is easy-to-use, it is suitable to promote.

Specific embodiment
Below in conjunction with accompanying drawing the utility model feature and other correlated characteristics are described in further detail by embodiment,
In order to the understanding of technical staff of the same trade：
As Figure 1-5,1-5 is marked to be expressed as in figure：Steel-pipe pile 1, sand outlet 2, angle bar hangnail 3, back cover steel plate
4th, H profile steel 5.
Embodiment：As shown in figure 1, the structure for reducing penetrating resistance in the present embodiment is applied on steel-pipe pile 1, to reduce it
Resistance during pile sinking is carried out using anchor rod static pressure in sand, silty soil, while the difficulty of pile sinking is reduced, increases applying for pile sinking
Work precision, it is ensured that the state after pile body pile sinking meets requirement.
As shown in figure 1, being provided with the pile top being made up of back cover steel plate 4 and H profile steel 5 at the stake bottom of steel-pipe pile 1.Wherein,
The top surface of back cover steel plate 4 is mutually welded and fixed with the bottom of steel-pipe pile 1, and now back cover steel plate 4 is sealed to the stake bottom of steel-pipe pile 1
Mouthful.As shown in figure 3, H profile steel 5 is weldingly fixed on the bottom surface of back cover steel plate 4, its outer profile size is less than the stake footpath of steel-pipe pile 1, from
And make H profile steel 5 form pile top, it is easy to be pressed into the soil body when steel-pipe pile is in pile sinking, while reducing end resistance.
As shown in figure 1, offering some sand outlets 2 on the side wall of steel-pipe pile 1, sand outlet 2 can make steel-pipe pile 1 heavy
Stake side powder, sandy soil during stake is entered into inside the stake holes of steel-pipe pile 1, so as to reduce pile side friction, and flows into steel-pipe pile 1
The interior sandy soil in hole is constantly piled up with pile driving process in stake holes.Pile body short transverse of some sand outlets 2 along steel-pipe pile 1
Be equally spaced, while and the pile body ring along steel-pipe pile 1 be arranged symmetrically, as shown in Figure 2, it is ensured that powder, sandy soil can be from uniform
Enter at the sand outlet 2 of arrangement among steel-pipe pile 1, it is ensured that the surrounding mean forced of steel-pipe pile 1 during pile sinking.Such as Fig. 1 and Fig. 2 institutes
Show, be respectively welded angle bar hangnail 3 in the outside of each sand outlet 2, angle bar hangnail 3 is sinking towards the outside top of steel-pipe pile 1
During stake, angle bar hangnail 3 can be inserted into it is disturbed among a side sandy soil, so as to reduce a packing for side sandy soil, make
Sandy soil is more readily flowed among steel-pipe pile 1, reduce further pile side friction.Meanwhile, sandy soil is that Jing angle bar falls
Again Jing sand outlets 2 flow into the inside of steel-pipe pile 1 after the disturbance of thorn 3, and now the particle of sandy soil more disperses, therefore can be effective
Sand outlet 2 is prevented to be blocked in pile driving process.
The present embodiment is in the specific implementation：The structure of existing ordinary steel pile tube 1 can be transformed by following steps,
Becoming can reduce the steel-pipe pile of penetrating resistance.
First, as shown in Figure 4 and Figure 5, some sand outlets 2, the position of sand outlet 2, hole are opened up on the side wall of steel-pipe pile 1
Footpath and quantity are explored parametric synthesis and are determined according to sandy soil layer thickness, packing, saturation state etc..After perforate, at each sand is let out
Weld angle bar hangnail 3 in the outside in hole 2.Then, in the bottom welding back cover steel plate 4 of steel-pipe pile 1, after the completion of under back cover steel plate 4
Square welded H section steel 5, the specification and length of H profile steel 5 calculate true according to engineering parameters such as sandy soil layer thickness, packing, pile driving pressures
It is fixed.So, by structure of modification so that existing ordinary steel pile tube can form the steel pipe for reducing penetrating resistance in sandy soil
Stake.
The size of back cover steel plate 4 determines according to the sectional dimension of steel-pipe pile 1.The specification of H profile steel 5 is according to back cover steel plate 4
Size determination, general optional H（150-300）×（150-300）Shaped steel.The aperture of sand outlet 2 is generally 10-20mm, steel-pipe pile 1
Same depth of section in 2-6 is set, the level interval of sand outlet 2 is 100-500mm.The size of angle bar hangnail 3 can set
It is set to its projection on the side wall of steel-pipe pile 1 and covers sand outlet 2, so as to further enhances the protected effect to sand outlet 2, it is to avoid
It is blocked in pile driving process.
Although design and embodiment of the above example referring to the drawings to the utility model purpose is elaborated,
But those skilled in the art will realize that under the precondition that scope is limited without departing from claim, still may be used
To make various modifications and variations to the utility model, such as：The aperture of sand outlet 2, the size of angle bar hangnail 3, the rule of H profile steel 5
Lattice and length etc., therefore here is not repeated one by one.
