Description
Technical field
The present invention relates to a kind of construction methods.
Background technology
When existing pile driving construction, Grouting Pipe is provided in the inner cavity or outside of pile pile, has a single function, performance is not highly desirable；
And the construction methods such as common static pressed pile, construction is complicated, and construction effect is bad, needs further to be improved.
Invention content
The purpose of the present invention is to provide a kind of easy for construction, construction methods of the good stake of effect.
Technical solution of the invention is：
The construction method of slip casting pipe pile in a kind of wall, it is characterized in that：
（1）When concrete tubular pile is prefabricated, it is embedded to slip casting steel pipe in pipe of concrete pile lining, is not only used as Grouting Pipe, but also as coagulation
The arrangement of reinforcement of native pile pile, a diameter of 1-5cm of slip casting steel pipe, quantity are 2-8, rounded equidistantly distributed；Slip casting steel pipe is mixed
There is screw thread injected hole at solidifying soil pile pile side and stake end, and the spacing in slip casting around pile hole is 50-500cm；At stake bottom, setting diameter is more than
The expansion end plate of pile pile outer diameter 1-30cm, end plate in the position box out of screw thread injected hole, end plate welded with pile body or with embedded pile body
Interior steel strand wires flexible connection, steel strand wires length are 5-30cm；Wireless pressure sensor is set in end plate；
（2）It, will by the way that spindle hollow steel tube is arranged between adjacent double section tube stake when single pile length needs more piece pile pile to connect
Slip casting fastener for connection, it is close that the upper and lower ends microcephaly of connecting tube is respectively embedded into blend rubber pad in the slip casting steel pipe of adjacent double section tube stake
Envelope, embedded length 3-10cm, for intermediate enlargement between adjacent double section tube stake, length is identical as pile pile connection length.
Static pressure method or hammer-impact construction can be used in construction pile pile：When using static pressure method, stake top screw thread injected hole and outside
Slip casting hose thread connects；When using hammering method, most upper stake side screw thread injected hole is connect with external slip casting hose thread；
External grouting equipment high pressure injects concrete and/or soil cement to pile sinking simultaneously, since bellend board diameter is more than pile pile outer diameter 1-
30cm generates gap between pile pile outer wall and the soil body, cutting soil also may be used when slurry injects gap by slip casting around pile hole high pressure
Increase gap, which can reduce the frictional force in construction, facilitate pile sinking；Concrete and/or soil-cement body in gap simultaneously
Intensity is higher after solidification, forms concrete and/or soil cement and pile pile composite pile, increases the bearing capacity and stability of stake.
When using static pressure construction and single pile is single-unit pile pile, the setting of stake bottom expands end plate and the steel in embedded pile body
Twisted wire is flexibly connected, and since there are Static pressure pile drivers after the completion of pile sinking can embrace tube drawing stake easily for stake side clearance, that is pulled out on pile pile is same
When end plate and pile body between detached due to pulling force, only connected by steel strand wires, can be pulled out at this time on pile pile by pile pile center cavity
Concrete and/or soil cement are injected in the gap of formation, seal stake top cavity with steel plate after pulling out on pile pile is part or all of
Extremely, pile sinking operation densification concrete and/or soil cement are carried out again, and it is compound with pile pile to form squeezed concrete and/or soil cement
Stake, increases the bearing capacity and stability of stake.
The present invention is easy for construction, and construction effect is excellent.
With reference to embodiment, the invention will be further described.
Specific implementation mode

The arrangement of reinforcement of native pile pile（Both have the function of slip casting, in turn ensure the intensity of pile pile, play the role of anti-folding, bending resistance, measuring body）, slip casting
A diameter of 1-5cm of steel pipe, quantity are 2-8, rounded equidistantly distributed；Slip casting steel pipe is equal in concrete tubular pile side and stake end
There is screw thread injected hole（Not only can downward punching press, but also can to side punching press, carry out antifriction）；The spacing in slip casting around pile hole is 50-
500cm；At stake bottom, setting diameter is more than the expansion end plate of pile pile outer diameter 1-30cm（Can be the abnormity such as cross, X-shaped, Y shape）,
In the position box out of screw thread injected hole, end plate is welded with pile body or is flexibly connected with the steel strand wires in embedded pile body, steel strand wires end plate
Length is 5-30cm；Wireless pressure sensor is set in end plate；
（2）It, will by the way that spindle hollow steel tube is arranged between adjacent double section tube stake when single pile length needs more piece pile pile to connect
Slip casting fastener for connection, it is close that the upper and lower ends microcephaly of connecting tube is respectively embedded into blend rubber pad in the slip casting steel pipe of adjacent double section tube stake
Envelope, embedded length 3-10cm, for intermediate enlargement between adjacent double section tube stake, length is identical as pile pile connection length.
Static pressure method or hammer-impact construction can be used in construction pile pile：When using static pressure method, stake top screw thread injected hole and outside
Slip casting hose thread connects；When using hammering method, most upper stake side screw thread injected hole is connect with external slip casting hose thread；
External grouting equipment high pressure injects concrete and/or soil cement to pile sinking simultaneously, since bellend board diameter is more than pile pile outer diameter 1-
30cm generates gap between pile pile outer wall and the soil body, cutting soil also may be used when slurry injects gap by slip casting around pile hole high pressure
Increase gap, which can reduce the frictional force in construction, facilitate pile sinking；Concrete and/or soil-cement body in gap simultaneously
Intensity is higher after solidification, forms concrete and/or soil cement and pile pile composite pile, increases the bearing capacity and stability of stake.
When using static pressure construction and single pile is single-unit pile pile, the setting of stake bottom expands end plate and the steel in embedded pile body
Twisted wire is flexibly connected, and since there are Static pressure pile drivers after the completion of pile sinking can embrace tube drawing stake easily for stake side clearance, that is pulled out on pile pile is same
