Abstract
The invention discloses a pile tip manufacturing technology. The pile tip manufacturing technology comprises the following steps: firstly, welding and fixing four steel plates, cutting and machining the cross section of the connected side of the four steel plates into an isosceles right triangle, fixing the four steel plates of the pile tip into a whole by angle welding; then, welding and fixing the four steel plates on a base plate; and finally, welding and fixing an end plate at the bottom end of a tubular pile, and welding and fixing the base plate on the bottom surface of the end plate. By adopting the cross taper type pile tip, the manufacturing technology is simple, the property of penetrating through deep and thick sand interlayer is enhanced, the successful drilling footage is realized, the total blow count of a single pile is controlled within 2500, and furthermore the fatigue failure of the pile body concrete is avoided effectively.
Description
Technical field
The present invention relates to the stake point.
Background technology
Present widely used stake point is flat cross, and it has the stronger ability that penetrates deep layer of sand.But for alluvium geology, owing to mud, layer of sand alternately deposit and the groundwater table height, its ability of breaking ground just is restricted.
Summary of the invention
Technical problem to be solved by this invention just provides a kind of sharp manufacture craft, and this prong is strengthened the ability of breaking ground to the stake point of alluvium geology.
For solving the problems of the technologies described above, the present invention adopts following technical scheme: a kind of sharp manufacture craft, the stake point comprises substrate, described substrate base vertically is welded with four block plates on the plane, described four block plates are that crossover arrangement is cross with the substrate base planar central, it is characterized in that: described steel plate is triangular structure of right angle, and the sharp manufacture craft of described stake comprises the steps:
At first, the welding of four block plates is fixing, and four block plates connect the side cross section by being cut into isosceles right triangle, are fixed as one by fillet welding between four block plates of stake point;
Then, four block plates are fixedly welded on the substrate;
At last, an end plate is fixed in welding in the pile tube bottom, and substrate is weldingly fixed on the end plate bottom surface.
Preferably, described steel plate is isosceles right triangle.
Preferably, described stake point is the Q235 welded construction.
Preferably, described end plate is the hollow reverse frustoconic, and end plate end face diameter is identical with the pile tube external diameter, and end plate bottom surface diameter is identical with substrate diameter.
The present invention adopts cross cone-shaped pile point, and its manufacture craft is easy, and it has strengthened penetrating the ability of deep skerry, has realized smooth drilling depth, and the total hammering numerical control of single pile has prevented the fatigue failure of pile concrete effectively in 2500 hit.
Description of drawings
Below in conjunction with the drawings and specific embodiments the present invention is further described:
Fig. 1 is the sharp plane structure schematic diagram of stake;
Fig. 2 is A-A sectional view among Fig. 1.
The specific embodiment
Specify the break ground stake point of ability of a kind of reinforcement below in conjunction with Fig. 1 and Fig. 2, this point 1 comprises the substrate 10 that is fixed in pile tube 2 bottoms, described substrate vertically is welded with four block plates 11 on 10 baseplanes, described four block plates 11 are that crossover arrangement is cross with the substrate base planar central, and described steel plate is triangular structure of right angle.
Concrete, described steel plate 11 is isosceles right triangle.Described stake point 1 is Q235 welded construction (comprising substrate and steel plate), fixes by the fillet welding structure between four block plates of described stake point.Be welded with end plate 20 between described pile tube bottom and the substrate.Described end plate is reverse frustoconic, and end plate end face diameter is identical with the pile tube external diameter, and end plate bottom surface diameter is identical with substrate diameter.
This sharp manufacture craft comprises the steps:
At first, 11 welding of four block plates are fixing, and four block plates connect the side cross section by being cut into isosceles right triangle, are fixed as one by fillet welding between four block plates of stake point;
Then, four block plates are fixedly welded on the substrate 10;
At last, an end plate 20 is fixed in welding in pile tube 2 bottoms, and substrate is weldingly fixed on the end plate bottom surface.
Following table is the size relationship table between stake point and the pile tube:
Following table is for using flat cross stake point and cross cone-shaped pile point effect contrast statistical form:
Can be drawn as drawing a conclusion by last table: cross cone-shaped pile point of the present invention has been strengthened the ability of breaking ground, and the total hammering number of single pile is controlled.
