Description
Technical field
The utility model relates to the Construction Technology field, particularly flush type construction construction of prefabricated piles technology, specifically a kind of flush type construction preformed pile pile feeding device.
Background technology
Engineering pile uses in engineering, finally build, stressed stake of working in the structure.Engineering pile is the stake that is used on the engineering entity, bear certain load.
At present, existing foundation pile construction mainly contains three kinds of modes: paddle type mill, static pressure type and flush type.Hammering and static pressure are the construction technologies of preformed pile of generally constructing, and flush type generally is job site fluid concrete stake.When hammering or static pressure construction preformed pile pile follower, adopt the steel bushing of making directly with hammering or static pressure preformed pile to be delivered to the predetermined degree of depth.Hammering or static pressure construction preformed pile pile follower need to not dig the pile anchoring hole in advance in the pile anchoring district, but this pile follower is smashed pile crown easily, owing to do not dig the pile anchoring hole, so works area subsurface geology situation also can't be accomplished very careful understanding, if stake is got on the stone of bulk, stake occurs to jump easily, and pile body and pile crown all can be broken, cause danger and waste.
Adopt the concrete pile of flush type job site cast then not need pile follower.The concrete pile of cast-in-site is that the pile anchoring hole has been dug in the pile anchoring district in advance, and the reinforcing cage of finishing is put into the pile anchoring hole, pours into concrete again, directly forms stake with reinforcing cage as skeleton in the pile anchoring hole.The defective of this construction technology be the concrete that pours into this as liquid, produce easily bubble when building, cause stake interior hollow, simultaneously, can be stuck on the reinforcing cage when concrete is pressed on the reinforcing cage sometimes, do not fall down, perhaps the soil block of bulk drops on the hole wall of pile anchoring hole, has tied up concrete position, causes necking down, disconnected neck, have a strong impact on the bearing capacity of stake, and this bad stake is difficult for being found.
Addressing these problems reasonable method is that paddle type mill, static pressure type and flush type are respectively got the chief, namely uses flush type construction preformed pile.
When adopting flush type construction preformed pile, the Pile feeder that then can't adopt hammering or static pressure to use, but the bolt apertures that screws on the pile end plate by screw is fixed stake and clip.This method constructional difficulties, clip is difficult to separate with stake.
Summary of the invention
