What is flange connection pile?
Classification of pilesWith the development of engineering technology, new steel pile and reinforced concrete pile are more and more widely used in engineering construction. Different pile types have different characteristics.Classification according to force condition:Friction piles - most of the load is carried by the friction of the soil around the pile, while the pile at the end of the pile can be neglectedPileEnd bearing friction pile -- the pile whose load is mainly borne by the friction force of the pile bodyEnd bearing piles - most of the load is carried by the supporting force of the pile tip, while the resistance at the side of the pile is negligibleFriction end bearing pile -- the pile whose load is mainly loaded by the end of pileClassification by construction method:Mechanical hole pileBored pileImmersed tube cast-in-place pileReinforced concrete pilePile foundation, precast pile, prestressed concrete pileSteel pileCement soil mixing pileMixing pileOther chemical material mixing pilesAccording to the overall size of the pile classificationLong pilePileShort pileMiddle long stakeVariable cross-section pileAccording to the method of pile driving, prefabricated piles can be divided into driven piles, pressed piles, vibrating sinking piles, rotary piles and so on.
Because of the length of a pile does not reach the depth prescribed by the design, the pile should be connected to the bottom of the pile until the depth of the design is reached. The process of connecting the top of the previous pile with the lower end of the last pile.The pile connection includes welding method, flange bolt connection method and sulfur clay anchor method.Flange bolt connection method is the two piles, first fixed on a flange, two flanges, plus flange pad, bolted together, completed the connection.The flange shall be used to meet the following requirements1, flange joints, pad can be asphalt paper and other materials, such as flange not tight, application of thin steel sheet plugged.2, the flange bolts should be tightened one by one, and add spring washers or welding, to prevent hammer when the bolt loose.3. The connection of the pile shall be carried out according to the design requirements or the relevant regulations.
Flange connection pile, as the name suggests, is to use flange to meet the pile. The main reason of the pile connection is that the long pile is needed in the construction, but the length of the pile is limited in actual production, so it must be long enough to meet the requirement, so the method that can be used in the construction is the flange connection pile.Flange pile - - in the upper and lower two piles on the flange plate, flange is processing pile foundation is installed in advance, when the connection is directly good to tighten it
