pile connection and pile cutting: it means that the pile needs to be cut off.
F represents that the reinforcement of the upper section is F-shaped pile (the reinforcement type can be divided into a / B / C / D / E / F / g.
Pile end plate: steel pile tip at the connection between pile foundation and pile foundation: set at the bottom of pile foundation, which is mainly used to make the pipe pile foundation easier to enter the rock and soil layer.
Example: what does “yz700-30-3.5,25 / c-c30” mean when it appears in the construction drawing? Solution: YZ stands for pressure cast-in-place pile, the initial letter of pressure; 700 means the pile diameter is 700mm; 30 represents the pile length of 30m; 3.5 represents the length of stirrup densification area of 3.5m; 25 represents the upper reinforcement length of 25m*/ C where C represents the reinforcement type C-type pile (the reinforcement type can be divided into a / B / C / D / E / F / g.
Example: how to read “phc-700 (125) ab-c80-7, 12, 15” in the construction drawing? Solution: interpret from left to right.
Actual photo of steel pipe pile supporting plate: set at the connection between pile and bearing platform.
20 represents the pile length of 20m.
Pile connection: it refers to the upper and lower mutual connection between steel pipe piles and steel pipe piles, that is, the pile end plates described above are welded and connected with each other.
The section area, height, thickness, single weight and weight per linear meter of U-shaped steel sheet pile can be queried according to the model.
The length of PHC and PC pipe piles is generally between 7-30m.
The wall thickness of PC pipe pile is 90mm, 95mm, 100mm, 110mm, 125mm and 130mm; The theoretical weight varies according to the outer diameter and the amount of reinforcement and concrete contained.
Generally, the weight of U-shaped steel sheet pile is between 95-150kg / m2.
The theoretical weight per meter is about 185-900kg / m.
Pile length = upper section reinforcement + lower section reinforcement + bottom reinforcement; 33.
It is divided into A-type open reinforcement, B-type flat bottom cross closed pile tip, C-type sharp bottom cross closed pile tip, D-type pyramid closed pile tip and E-type steel plate cone concrete closed pile tip.

The outer diameter of pile foundation can be divided into 350, 400, 450, 500, 550, 600, 700, 800 and 1000mm.
22.
10 represents that the reinforcement length of the upper section is 10m.
The construction technology of steel pipe pile mainly includes pile sinking, pile extension, pile cutting, etc.
The specific construction method shall be considered according to the actual situation.
PHC stands for prestressed high-strength concrete pipe pile (PC stands for prestressed concrete pipe pile, with H is high-strength cast-in-place pile, without H is precast pile, not high-strength pile); 700 represents the diameter of pile foundation φ 700 (note that this is not a radius); AB stands for pile foundation model; C80 represents that the concrete strength grade of pile foundation is C80; 7 represents the length of the first section of pile 7m; 12 represents the length of the second section of pile 12m; 15 represents the length of the third section of pile 15m; The tip of steel pipe pile is PHC and PC pipe pile.
The theoretical weight per meter is about 184-889kg / m.
the quantity of longitudinal reinforcement, stirrup model and the size of stiffener can be queried according to the pile diameter, concrete strength grade and reinforcement form); C30 represents the concrete strength grade C30.
the quantity of longitudinal reinforcement, stirrup model and size of stiffener can be queried according to the pile diameter, concrete strength grade and reinforcement form).
Example: what does “crsp-z-835” mean when it appears in the construction drawing? Solution: it represents Z-type cold-formed steel sheet pile, 835 represents model, and others are the same as above.
Pipe pile is mainly composed of pile supporting plate, pile end plate, pile body, steel pile tip, etc.
It is classified according to the section modulus of U-shaped steel sheet pile.
Example: what does “bz600-20-10 / F, c-c30” mean when it appears in the construction drawing? Solution: BZ stands for cast-in-place pile, in which B stands for the initial letter of uplift resistance.
C30 represents the concrete strength grade C30.
The wall thickness of PHC pipe pile is 90mm, 95mm, 100mm, 110mm, 125mm and 130mm; The theoretical weight varies according to the outer diameter and the amount of reinforcement and concrete contained.
Pile length = upper section reinforcement + lower section reinforcement + bottom reinforcement; 44.

According to different load forces, pipe piles can be divided into a, AB, B and C types; According to the concrete strength grade, the PHC Concrete strength grade shall not be lower than C80, and the PC concrete strength grade shall not be lower than C60.
The pile sinking method can be diesel hammer, hydraulic hammer and other hammer driving methods, or top pressure and holding pressure static pressure pile sinking methods.
J.
For example, what does “crsp-u-296” or “crsp-u – * * *” mean when it appears in the construction drawing? Solution: it stands for U-shaped cold-formed steel sheet pile, in which u stands for U-shaped steel sheet pile, and 296 stands for the model of U-shaped steel sheet pile.
