Technical field
It the utility model is related to a kind of basic pile pipe, specifically a kind of carbon steel coil stake with rotor.
Background technology
At present, the basic species of engineering field is a lot, mainly there is concrete foundation and prefabricated pile basis.Concrete foundation one
As ground excavated using large area, then make reinforced concrete foundation, spend substantial amounts of man power and material, and construction period and
The concrete curing phase is all longer；Prefabricated pile basis includes concrete-pile and piling bar, is directly hammered onto it using special piling machine
In soil, although this method short construction period, the engineering equipment used is huge, destruction during construction to surrounding environment compared with
Greatly, noise caused by piling is very big, and the current whole society is to environmental requirement more and more higher, the side for prefabricated pile of being constructed using piling machine
Method gradually decreases.
In order to solve the difficult difficulty with cycle length of the foundation construction of engineering field, rotation mode is employed by foundation pile spinning
To soil, ground surface environment is not destroyed, does not produce construction noise, have obvious progress than traditional paddle type mill.In order to meet
The demand of engineering field foundation construction, draws the experience of external rotating basis stake, and we are carried out on the basis of existing foundation pile
Improve, it is preferably satisfied with the form of construction work of rotation.

Upper remaining 1m is more, and now screen display pile body carrying is inadequate.In order to increase the bearing capacity of pile body and uplift force, it is necessary to which straight type is oriented to
Pipe 1 is connected with straight type extension tube 3, increases the total length of carbon steel coil stake.By the straight upper end of type guide pipe 1 and straight type adapter sleeve 5
Bellmouth connects, and is formed a whole with 4 connections of M64 bolts 6, now by the upper end insertion rotating head of straight type extension tube 3
Blending bolt 6 is fixed, then is driven by rotating head, and pile body continues to be spun in soil, until computer shows that torque value meets
Untill fundamental importance, illustrate the requirement for bearing capacity that this branch carbon steel coil stake has reached, now pile body there remains 0.9m on the ground.
The ground remainder of pile body is cut into height 0.3m from the ground with instrument, then welded pile body and sole plate
It is connected together, such lower margin basis completes.
4 lower margin bases are made with same method, complete the basis of a base electricity tower.
Other two bases electric tower foundation is made with same procedure, so far three base electric tower foundations are fully completed.
After after testing, the bearing capacity on the lower margin basis of this three bases electricity tower reaches design requirement.
Electric tower lower margin is installed in carbon steel coil pile foundation, continues to assemble electric tower and stringing.
Finally it should be noted that：Various embodiments above is only to illustrate the technical solution of the utility model, rather than it is limited
System；Although the utility model is described in detail with reference to foregoing embodiments, one of ordinary skill in the art should
Understand：It can still modify to the technical scheme described in foregoing embodiments, either to which part or whole
Technical characteristic carries out equivalent substitution；And these modifications or replacement, the essence of appropriate technical solution is departed from this practicality newly
The scope of each embodiment technical scheme of type.
