Specific implementation mode
The invention will be further described in the following with reference to the drawings and specific embodiments.
Refering to fig. 1, it is shown that the sectional view of the Construction State of the construction method of the anti-collapse hole of rotary digging stake of the present invention.Fig. 2 is Fig. 1
Vertical view.As depicted in figs. 1 and 2, the construction method of the anti-collapse hole of rotary digging stake of the present invention includes the following steps：
In setting position construction rotary digging stake 10；
When the construction of rotary digging stake 10 to the easy region that collapse hole occurs, a setpoint distance is excavated to the easy region that collapse hole occurs；
The cylinder 20 that one outer diameter is less than 10 bore of rotary digging stake is provided；
Cylinder 20 is put into rotary digging stake 10, and the bottom of cylinder 20 is placed in the region that collapse hole easily occurs, cylinder 20
An annular gap is formed between periphery and the side wall of rotary digging stake 10；
Into annular gap, casting concrete is in one section of dado structure of formation on the side wall of rotary digging stake 10；
Cylinder 20 is taken out out of rotary digging stake 10, continues to excavate 10 to one setpoint distance of rotary digging stake downwards, by 20 weight of cylinder
Newly be put into rotary digging stake 10, and pour and to form one section of new dado structure, repeat the step until rotary digging stake 10 by easy hair
The region of raw collapse hole；
Rotary digging stake 10 is excavated until the construction of rotary digging stake 10 is completed.
The present invention is poured by cylinder being positioned in rotary digging stake and is placed in the region that collapse hole easily occurs using concrete
It builds in the annular gap stayed and set between rotary digging stake and cylinder, forms one section of dado structure to prevent collapse hole, i.e., in rotary digging stake
Four Mondays enclosed a small range and form concrete guard wall structure, prevented collapse hole, cylinder from being occupied during casting concrete centainly
Space saved resource the problem of avoiding entire anti-collapse hole all casting concretes and form waste and improved construction effect
Rate.Dado structure can be taken off cylinder after being formed, continue to excavate rotary digging stake downwards, cylinder can reuse, easy for installation.
One better embodiment of the construction method as the anti-collapse hole of rotary digging stake of the present invention easily occurs in the present embodiment
Mainly there are water-rich sand layer geologic province and backfill region in the region of collapse hole.The sand grain content of water-rich sand layer is up to 30% or more, hole
For gap than big, water content is big, has the characteristics that mobility is big, bearing capacity is small, self-stability is poor.Water-rich sand layer is easy to generate soil because excavating
Position is moved and is settled.Backfill refers in engineering construction, after completing the below grounds engineerings such as basis, then returns the soil tamped,
Therefore equally also has the characteristics that the problems such as bearing capacity is small, self-stability is poor, is easy to happen collapse hole.Easily occur collapse hole region not with
This is limited, and further includes the soil layer of other self-stabilities difference.
One better embodiment of the construction method as the anti-collapse hole of rotary digging stake of the present invention, rotary digging stake is inserted in by cylinder 20
During in 10, by the center overlapping of axles of the central shaft of cylinder 20 and rotary digging stake 10, the side of such cylinder 20 and rotary digging stake 10
The even width set everywhere in an annular gap is stayed between wall, prevent the uneven thickness for subsequently pouring the dado structure 30 to be formed and
Cause the effect of anti-collapse hole bad.
Specifically, cylinder 20 is steadily hung to the surface of rotary digging stake 10, cylinder 20 is slowly put into the need of rotary digging stake 10
The position to be backfilled, and the distance between the side wall of cylinder 20 and rotary digging stake 10 is strictly controlled, avoid the decline in cylinder 20
The problem of cylinder 20 collides the side wall of rotary digging stake 10 and damages rotary digging stake 10 occurs in journey.
One better embodiment of the construction method as the anti-collapse hole of rotary digging stake of the present invention, top to the bottom of cylinder 20
Lateral cross-sectional area is gradually reduced, and cylinder is subsequently lifted to taking-up upwards to facilitate.Cylinder 20 is inserted in the mistake in rotary digging stake 10
Cheng Zhong, the top of cylinder 20 are less than the top of rotary digging stake 10.The length of cylinder 20 is less than the depth of rotary digging stake 10, makes cylinder in this way
The material cost of body 20 is few, is moved easily and installs cylinder 20.
One better embodiment of the construction method as the anti-collapse hole of rotary digging stake of the present invention, pours mixed in an annular gap
During solidifying soil, casting concrete to the top of cylinder 20.Pour to form one section of dado structure in the bottom of rotary digging stake 10
30, it is supported with being reinforced to the bottom of rotary digging stake 10, prevents collapse hole.The depth of the length and dado structure 30 of certain specific cylinder 20
Degree is depending on the needs of practical rotary digging stake 10.
One better embodiment of the construction method as the anti-collapse hole of rotary digging stake of the present invention, refering to Fig. 3, it is shown that the present invention
The schematic diagram of anti-collapse aperture apparatus.In conjunction with shown in Fig. 1 to Fig. 3, the top of cylinder 20 is equipped with sealing cover 21.In the present embodiment, close
Capping 21 is pyramid type lid.
The top of cylinder 20 is equipped with connection ring 22, for being connected with tower crane, for lifting and moving cylinder 20.In this implementation
In example, connection ring 22 has 4, and 4 connection rings 22 are symmetrical arranged, and ensures the balance of cylinder 20 during facilitating lifting cylinder 20
Property.
Specifically, it is using steel wire rope, tower crane that cylinder 20 is steady after manufactured cylinder 20 is transported to scene by lorry
It slings, when wire rope handling should determine that the center of gravity of cylinder 20, lifting rope are hitched securely, then by 20 slow raising of cylinder, it is necessary to keep cylinder 20
Balance.Recycle tower crane that cylinder 20 is steadily hung to the surface of rotary digging stake 10, cylinder 20, which is slowly put into rotary digging stake 10, needs
Position is backfilled, and strictly control cylinder 20 avoids the generation cylinder 20 during declining from touching at a distance from the side wall of rotary digging stake 10
The problem of hitting rotary digging stake 10.
After the completion of cylinder 20 is placed, the casting concrete between cylinder 20 and rotary digging stake 10 waits for concrete initial set, reaches shape
After effect at anti-collapse hole, cylinder 20 is slowly sling, then puts to designated position and waits reusing.
The present invention also provides a kind of anti-collapse aperture apparatus of the construction method for the anti-collapse hole of rotary digging stake, including outer diameter to be less than
10 bore of rotary digging stake and the cylinder 20 for being inserted in rotary digging stake 10 and being located at the region that collapse hole easily occurs, cylinder 20 and rotary digging
It is stayed between the side wall of stake 10 and sets an annular gap；And pour one section of dado structure 30 in an annular gap.
Cylinder 20 is made using steel plate, steel plate thickness 3.6mm.Top surrounding draw ring is processed into 20mm thickness radiuses 100mm
Semicircle shape connection ring 22, the link as steel wire rope.According to the size of live rotary digging stake, process in advance various sizes of
Cylinder 20.
The top of one better embodiment of the construction method as the anti-collapse hole of rotary digging stake of the present invention, cylinder 20 is equipped with sealing
Lid 21.The top of cylinder 20 is equipped with connection ring 22.
