One is by the way of single pile cap, another kind is by the way of being inserted into pile crown in steel column, and pile is required for first transferring steel
Casing.
1, by the way of single pile cap
Using the way of single pile cap, it is that steel pile casting is first descended to drill, steel pile casting is extracted after pile, then excavate around cushion cap
The soil body, formwork pour cushion cap.2.5D must be reached since specification regulation steel column is inserted into cushion cap depth, D is steel column diameter or long side
The length of side, cushion cap height are generally higher.Method of the verticality of steel column adjustment mode mainly by embedded column bolt below cushion cap at this time
It is adjusted, cushion cap will pour at twice.The shortcomings that way, has：
1) cushion cap is higher, and cutting depth is deeper, and generally 2 to 3m.Excavation is deeper, larger to periphery soil disturbance；
2) be to meet the requirement of stake back gauge, cushion cap sectional dimension is larger, by taking 1m diameter stakes as an example, sectional dimension be 2m ×
2m.It is larger to excavate range, it is larger to periphery soil disturbance；
3) it needs to cut larger pile crown, speed of application is slower；
4) it needs to extract steel pile casting, withdrawal process is big to soil disturbance.
2, the mode of pile crown is inserted into steel column
It is equally that steel pile casting, stake top is first descended to be poured using retarded concrete that the way of pile crown is inserted into steel column, then will weldering
The shortcomings that steel column for connecing peg is inserted into stake top and adjusts verticality, this method has：
1) it needs stake diameter at least bigger 400mm than steel column long side, when steel column sectional dimension is larger, is not suitable for；
2) the larger requirement for causing to be not easy to meet 3 times of stake diameters as defined in specification with existing pile centre-to-centre spacing of stake diameter；
3) verticality of steel column Adjustment precision is poor, needs the measure of additional fixation steel column, such as ground fixed frame；
4) foundation pile concrete is not up to prescribed strength, and steel column must be just installed when being unsatisfactory for testing conditions, if pile detection
Unqualified, steel column and foundation pile cancel together.
In conclusion needing construction to be protected for closing on Important building, historical relic's protection building, railway line, subway line etc.
For building the newly-built reconstruction and extension project of object, there is disadvantage in currently used two kinds of pile base construction methods, use cushion cap when cushion cap
It is unacceptable when protecting more demanding to excavate the disturbance to the soil body, needs stake enlarged-diameter when being inserted into pile crown in steel column,
It is also unacceptable when distance is unsatisfactory for 3 times of stake diameters.
So needing construction of structures to be protected for closing on Important building, historical relic's protection building, railway line, subway line etc.
Newly-built reconstruction and extension project for, find a kind of to periphery soil disturbance very little, of less demanding to stake diameter, column verticality being capable of essence
The pile foundation construction and steel kind design way really adjusted is engineering problem to be solved in practice.
