Note pilework.
Utility model content
The purpose of this utility model is to provide a kind of piles set into rock structure, and construction technology is simple, filling pile structure letter
It is single, short construction period.
Above-mentioned purpose of the present utility model technical scheme is that：A kind of piles set into rock structure,
Including prefabricated pile, in addition to stake reaming, stake reaming is located in rock stratum, and prefabricated pile is arranged in a reaming and diameter is more straight than stake reaming
Footpath is small, and provided with some pieces of fixation steel plates in stake reaming, fixation steel plate is uniformly connected to around prefabricated pile, is cast with stake reaming
Wrap up above the concrete basis of prefabricated pile and fixation steel plate, rock stratum covered with soil layer.
By using above-mentioned technical proposal, because rock stratum hardness is high, common piles set into rock construction technology is difficult, the duration
It is long, and the reliability of bored concrete pile is not good, and stake reaming is bored in rock stratum, the diameter range of stake reaming is big, reduces to pore size
Requirement；Overlying soil can reduce the depth of a reaming above rock stratum, so as to reduce boring work amount；Prefabricated pile expands with stake
Fixation steel plate and pour concrete basis are set between hole, the stability of prefabricated pile is further increased.
It is preferred that, prefabricated pile bottom is provided with circumferentially distributed neck, and one end of fixation steel plate is goed deep into neck, the other end
It is resisted against a reaming inwall.
By using above-mentioned technical proposal, fixation steel plate is connected on prefabricated pile, on the one hand easy to connect and firm, another
Aspect makes prefabricated pile have simple structure, and technique is simpler during stake processed.
It is preferred that, prefabricated pile is reserved slip casting passage and extended at the top of prefabricated pile provided with least two reserved slip casting passages
To neck bottom, the through hole of reserved slip casting passage is communicated with fixation steel plate.
By using above-mentioned technical proposal, when pour concrete is basic, it might have some solid impurities and infiltrate in concrete,
Or concrete is filled up completely with a reaming and produces defect, causes to connect unreliable between rock stratum, prefabricated pile and soil layer, toward in advance
Stay the connection of cast grouting further between reinforcement prefabricated pile, concrete basis, fixation steel plate in slip casting passage so that bored concrete pile is more steady
Gu, improve the bearing capacity and quality of stake.
It is preferred that, reserve and slip casting steel pipe is provided with slip casting passage.
By using above-mentioned technical proposal, the quality for setting slip casting steel pipe to improve prefabricated pile in slip casting passage is reserved, is reduced
The defect that prefabricated pile is produced when manufacturing, reinforcement structure intensity, so that bored concrete pile has firm, reliable bearing capacity.
It is preferred that, the depth of stake reaming is between 0.5d ~ 1.5d of prefabricated pile, d is prefabricated pile diameter.
By using above-mentioned technical proposal, on the one hand the depth of stake reaming can reduce drilling in above-mentioned number range
Difficulty, on the other hand can ensure the steadiness of bored concrete pile again.
It is preferred that, between 1.5d ~ 2d of a diameter of prefabricated pile of stake reaming, d is prefabricated pile diameter.
By using above-mentioned technical proposal, the diameter of stake reaming is arranged in above-mentioned number range, on the one hand can be reduced
The difficulty that requirement during drilling to bore dia is caused, on the other hand can pour into a mould appropriate concrete so that concrete it is basic with it is prefabricated
Strong bonded between stake, rock stratum, soil layer.
It is preferred that, concrete basis is slag concrete.
By using above-mentioned technical proposal, slag concrete has good heat endurance, water stability, it is possible to increase concrete basis
Durability, reduce construction costs, save natural resources.
To sum up, a kind of piles set into rock structure described in the utility model, manufacturing process is simple, construction technology is easy, apply
The work cycle is short；Cost is low, quality is high, and load-carrying properties are excellent.
