The construction usage method of the utility model is：A kind of novel Prefabricated composite stake, when construction, using stake machine by prefabricated group
It closes stake and slowly squeezes into designed elevation in ground, the verticality of pile body is no more than 0.5% during control is squeezed into；By Prefabricated composite
After Foundation Design absolute altitude is squeezed into stake, a machine is removed, high-pressure slip-casting equipment is connected with the hollow part of stake top carries out slip casting behaviour
Make, slurries is made to enter inside pile body, slurries are full of behind pile body inside is exuded to stake week soft soil layer from injected hole, and fills up top
Gap between pile body and surrounding soil layer is combined as a whole with top pile body and wedge-shaped wing plate after hardening, completes construction.
The operation principle of the utility model is：A kind of novel Prefabricated composite stake, top pile body big section pile body periphery are equipped with
Wedge-shaped wing plate increases the contact area with surrounding soil, is mounted in soil layer, improves pile side friction；Big section up and down
It is equipped with arc floor between pile body, big section pile body is linked together, the stability and bearing capacity of pile body, big section are improved
Pile body and small bore pile body alternate combinations, it is bamboo joint pile to keep stake similar, to improve pile side friction；Small bore pile body is equipped with
Injected hole injects slurries in gap that can be between stake and soil, forms Seed harvest, so that pile body is connect with surrounding soil more firm
Gu to be reinforced to stake week ground, pile body bearing capacity is improved；Lower part pile body pile body cross section by lower gradually
Reduce, be variable cross-section pile body, pile body side wall increases the contact area of pile body and surrounding soil by the way that the edge of a wing is arranged, improves stake
Side friction；The edge of a wing can be closely linked with the soil body, keep pile body stress and earth stress harmonious, to increase stake
The firm performance and compressive property on basis；Top pile body small bore pile body is equipped with injected hole, in gap that can be between stake and soil
Slurries are injected, Seed harvest is formed, so that pile body is connect with surrounding soil more secured, to be reinforced to stake week ground, are carried
High pile body resistance to compression resistance to plucking bearing capacity.
The utility model has the beneficial effects that：A kind of novel Prefabricated composite stake, lower part pile body cross section are gradual from top to bottom
Reduce and the edge of a wing and pile body angle are 30 °, can relatively easily squeeze into ground, top big section pile body periphery is equipped with wedge shape
Wing plate, and arc floor is equipped between big section pile body up and down, wedge-shaped wing plate and arc floor can generate association with the soil layer of surrounding
Same-action can be effectively improved the physico-mechanical properties of pile peripheral earth, to improve pile body bearing capacity；Small bore pile body is equipped with
Slurries are injected in the gap that injected hole can be between stake and soil, are formed Seed harvest, so that pile body is connect with surrounding soil more secured,
