Background technique
In geotechnical engineering field, steel pile casting is widely used, and can be used for cast-in-situ bored pile, column construction.But in water rich strata
In, easily there are the defects such as recycling is difficult, pile vertical precision is low in the use of steel pile casting.This is because water rich strata is protected using steel
Tin, it is difficult to create dry work space in cylinder, when placing steel reinforcement cage and steel pipe column, staff can not assist making down toward cylinder bottom
Industry, and verticality calibration can not be carried out, therefore the error of perpendicularity often occur.Stake, column verticality to safety of structure shadow
It rings greatly, for pilework, usual verticality tolerance is less than 1%；For rod structure, usual verticality tolerance is small
In 0.1%, when perpendicularity deviation value is more than that limit value requires, need to take other reinforcement measures or do over again to reform by regulation.It presses
Traditional construction technology, when water rich strata uses steel pile casting, because of casing internal water accumulation, staff can not assist down toward cylinder bottom
Operation, stake, column verticality require to be difficult to reach, and bring larger hidden danger to the safety of structure.

The inner wall upper end of portion's casing is equipped with lower connecting flange, and the inner wall of the top casing is equipped with the upper company connecting with lower connecting flange
Acting flange；The lower part casing, which is extend between the outer wall in the casing inner wall of top and the inner wall of top casing, is equipped with sealing knot
Structure.
Preferably, the water sealing structure includes two fixed rings and the seal ring that is arranged between two fixed rings, institute
It states seal ring to be fitted between lower part casing upper end outer wall and top casing lower end inner wall, plays sealing effect.
Preferably, the top casing and lower part casing are hollow circular ring structure.
Preferably, the lower part casing height is 2~3m.
Preferably, the lower part casing outer diameter is 15~25mm smaller than top casing internal diameter.
Preferably, lower part casing bottom is equipped with back cover concrete, the back cover concrete is with a thickness of 1m.
A kind of construction method of slotting formula drilled pile steel pile casting, comprising the following steps:
A, using flange bolt assembly top casing and lower part casing, the steel pile casting after assembly is constructed into stratum；
B, Rock And Soil in cylinder is excavated, back cover is carried out using Cast-in-place concrete after drawing water, to create dry work space, cableway
Cage or steel pipe column；
C, staff is down toward the less important work of cylinder bottom, and checks the verticality of pile, after check, opens flange, complete
The construction of pile, column；
D, top casing is recycled.
The beneficial effect that the present invention obtains is: the upper end of lower part casing of the invention is nested into the lower end of top casing,
Top casing is fixedly connected with lower part casing by flange, and structure is simple, easy to use.Lower part casing is extend into the casing of top
Water sealing structure is equipped between outer wall in wall and the inner wall of top casing, the seal ring in water sealing structure can effectively prevent external water
Into in casing, guarantee construction safety.
Construction stake, column can be facilitated in water rich strata using the present invention, especially in sheltered reverse excavation steel structural upright column,
Working space can be created for artificial less important work, guarantee the verticality requirement of structure, guarantee the safety of pile structure.Scene
When construction, the advantages of remaining traditional construction mode, is easy to construction personnel's receiving.Operation of the present invention is simple, flexible, use cost
It is low, it is practical.
