Abstract
The invention relates to a graded mounting construction method for a super-long protective cylinder of a rotatably excavated cast-in-situ bored pile. The method comprises the following steps: vibrating and infiltrating a relatively short first stage steel protective cylinder by using a plate inserting machine modified by a vibrating hammer of an excavator; then borrowing earth by using a rotary drilling rig to the bottom of the first stage steel protective cylinder; then hoisting a super-long second stage steel protective cylinder to the first stage steel protective cylinder by using a truck-mounted crane; and then replacing the truck-mounted crane by a plate infiltrating machine to infiltrate the second stage steel protective cylinder underground in a vibrating manner to be aligned to the elevation of the top of the first stage steel protective cylinder to accomplish super-long steel protective cylinder mounting work. According to the graded mounting construction method for the super-long protective cylinder of the rotatably excavated cast-in-situ bored pile provided by the invention, operation is carried out by using the plate inserting machine, so that the method is simple and convenient to operate in construction, the work efficiency is improved, the quality control is ensured, and the construction cost is also lowered. The method can solve the technical problems that the requirement on construction space is relatively high as the super-long protective cylinder is buried by adopting a large carterpillar crane equipped with the vibrating hammer when the conventional rotatably excavated cast-in-situ bored pile carries out construction on relatively thick adverse stratum, and the large equipment operation is low in work efficiency and high in cost and the like.
Description
Technical field
The present invention relates to a kind of rotary digging drilling hole bored concrete pile overlength casing is classified construction method of installation, especially one kind is to routine
Rotary digging drilling hole bored concrete pile overlength casing installs the construction method being optimized.
Background technology
With economic development, artificial marine reclamation land becomes a big way of the new production of coastal area acquisition and construction land
Footpath, associated ground foundation engineering project is more and more.Compared with conventional land-based area is constructed, reclaimation area geographical environment is special,
Complex geologic conditions.Often there is the unfavorable soil layers such as loose artificial earth fill and current-formed silt layer in artificial reclaimation area, if here
Pore-forming operation under geological conditions, is only likely to collapse hole or necking down quality accident on a large scale by mud off.In order to overcome
This unfavorable factor affects, and the steel pile casting that overlength can be installed during construction passes through poor strata, then the work for carrying out rotary digging drilling hole construction
Industry method.When overlength casing is installed, because overlength casing inherently there are 15 ~ 20 m high, vibration hammer and operation height are added, often
Large caterpillar is needed to meet demand.Large caterpillar construction cost is high, also has extra bearing capacity to want to construction site
Ask；In addition, crawler crane build is huge, the highly desirable bigger construction space of higher barre, in some land areas and height
The inadequate construction area of degree just cannot flexibly put to good use；Additionally, the slow motion of giant caterpillar loop wheel machine, work efficiency is relatively low.
The content of the invention
The present invention is to provide for a kind of rotary digging drilling hole bored concrete pile overlength casing classification construction method of installation, and the method can be realized
Overlength casing high efficiency, low cost are embedded, when solving conventional rotary digging drilling hole bored concrete pile overlength casing installation, it is necessary to using big
The technical problem of type crawler crane, with relatively higher economic implications and social value.
For achieving the above object, the present invention is achieved by the following technical solutions：
A kind of rotary digging drilling hole bored concrete pile overlength casing is classified construction method of installation, and its step is：
1）The board-plugging device of vibration hammer repacking is equipped with using excavator, vibration on excellent stake position is put first order steel shield is squeezed into
Cylinder, high 30 cm above ground level of first order steel pile casting top mark, aperture arranges extravasating hole, and first order steel pile casting internal diameter is protected than the second level
Big 10 cm of external diameter of cylinder；
2）Soil taking hole forming is dug in first order steel pile casting inward turning using Spiral digging machine, until first order steel pile casting bottom；
3）Second level overlength steel pile casting is hung to first order steel pile casting using truck crane, is hung and reveal after first order steel pile casting
Go out hole position about half height；
4）Second level overlength steel pile casting vibration is driven underground using board-plugging device, until second level overlength casing top and first order steel
Casing top mark height is flushed, and is completed long casing classification and is installed.
The second level overlength steel pile casting external diameter is identical with cast-in-situ bored pile design stake footpath, and length is first order steel pile casting 2
Times.
Beneficial effects of the present invention：
1st, steel pile casting is longer, and perpendicularity is more difficult to control to.Overlength casing is disposably buried using giant caterpillar loop wheel machine with vibration hammer
During installation, degree control difficulty is larger, often has occurred having pulled out and bury again phenomenon.If overlength casing, first order steel shield are installed in classification
Cylinder is halved due to length, and degree control difficulty is reduced；Second level overlength steel pile casting hangs down under first order steel pile casting guide-localization
Straight degree control ratio is more accurate, so as to improve pouring pile hole perpendicularity quality.
2nd, crawler crane build is huge, and mobility is poor in construction area, and work efficiency is relatively low.The present invention adopts excavator
Being equipped with the piling machine of vibration hammer repacking carries out operation, and constructing operation is easy, efficiency of construction is high.
3rd, excavator is equipped with the piling machine replacement main equipment crawler crane outfit vibration hammer of vibration hammer repacking, has saved work
Cheng Chengben.
4th, the long casing of rotary digging drilling hole bored concrete pile is classified mounting technique construction method, supplements domestic overlength casing and installs skill
Art, improves operating efficiency, reduces engineering cost, and job site arrangement is more flexible, possesses certain social effect.

Specific embodiment
Below in conjunction with the accompanying drawings the invention will be further described with embodiment.
The rotary digging drilling hole bored concrete pile overlength casing of the present invention is classified construction method of installation, and its step is：
Step one, as shown in figure 1, with excavator be equipped with vibration hammer repacking board-plugging device 1, beat having put well to be vibrated on sample stake position
Enter first order steel pile casting 3, the top of first order steel pile casting 3 preferably 30 cm above ground level.
Step 2, as shown in Fig. 2 the drilling construction in place of rotary drilling rig 4, fetch earth until the bottom of first order steel pile casting 3.
Step 3, as shown in Figure 3, Figure 4, is hung second level overlength steel pile casting 6 to first order steel pile casting using truck crane 5
In 3, second level overlength steel pile casting 6 exposes the half height of stake holes one.
Step 4, as shown in Figure 5, Figure 6, the board-plugging device 1 of vibration hammer repacking is equipped with by second level overlength steel shield with excavator
Cylinder vibration is squeezed into, until second level overlength steel pile casting is concordant with stake holes mouth, that is, is completed the classification of overlength casing and is installed, then using rotation
Digging rig can complete follow-up routine rotary digging drilling hole bore forming.
