Description
Technical field
The utility model is related to the technical field of radical filling pile construction, and in particular to a kind of root key of radical bored concrete pile is applied
Frock is put.
Background technology
In building field, pile foundation generally contributes to pressure-bearing, and pile foundation passes through pile side resistance and the common work of end resistance
With carrying out pressure-bearing.The drag size that the size of bearing capacity of pile foundation and stake side, stake end are provided is relevant, by increase pile foundation diameter or
The length of pile foundation, i.e., can improve the pile side resistance or end resistance of pile foundation, and then improve pile foundation by increasing the area of stress
Bearing capacity.But in actually building, the length of pile foundation is longer, and the difficulty of construction is bigger；The diameter of pile foundation it is bigger, it is necessary to
Building materials it is more, the construction cost of pile foundation is higher；The lifting of final pile foundation pressure-bearing effect compared to pile foundation construction difficulty and
It is disproportionate for construction cost.The diameter of this simple increase pile foundation or the method for length are, it is necessary to consume substantial amounts of coagulation
Soil, the difficulty of construction is larger, not economical enough.
Applied before the applicant one it is entitled《Radical pressure-bearing bored concrete pile and its construction method》Patent, solve
Above-mentioned technical problem.But in actual production work progress, it is relatively complicated for the construction of the root key of radical stake.Mesh
Typically it can be all applied in preceding work progress《Tech enterprises in China》The root key machine published in the 34th phase in 2013 carries out root
The construction of key, but there is Railway Project in above-mentioned key machine.
Firstth, in whole work progress, hanging apparatus is required for, causes construction cost very high.
Secondth, constructed under lifting state, although instead of lifting rope with suspension rod, improve certain rigidity,
But still suffer from rocking generation, this is a great potential safety hazard in work progress.
3rd, it is slope structure by the part of root key jacked pile hole side wall, slope structure is when acting on root key, together
Food can produce the active force of a vertical direction, when cheating side wall to root key jacked pile, root key can be caused can not to ensure level
Head into, it is impossible to ensure the construction quality of root key.
4th, same layer root key top enters the quantity of root key is influenceed larger by the domatic quantity of each angle, and domatic shared
Volume it is larger, causing the upper limit of domatic quantity is restricted.
5th, because domatic refers to larger, and need to bear certain pressure, so domatic weight is larger, increase
The load of lifting is added, the weight capacity of loop wheel machine needed for causing requires higher, further increases construction cost.
The content of the invention
