A kind of construction method that Dense Broken Stone Peg shaping is carried out using the present embodiment as shown in Figure 3, this method include with
Lower step：
Step 1: preparation of construction：Behind smooth construction site, city's roads are carried out to the stake position of constructed Dense Broken Stone Peg 5,
Rotary rig is moved at the stake position present position of Dense Broken Stone Peg 5 again, makes brill door 2 positioned at 5 positions of Dense Broken Stone Peg of constructing
Surface, while the drilling rod 1 is laid in vertical, refers to Fig. 4；
Step 2: drilled as holes under drilling rod：Start the drive device, the drive device drives the drilling rod 1 counterclockwise
Rotation, and by controlling the drive device drilling rod 1 is at the uniform velocity crept into straight down, now the brill door 2 is closed form
State, until at brill door 2 drilling to the stake bottom absolute altitude for Dense Broken Stone Peg of constructing, the drive device is closed, makes the brill
Bar 1 stops the rotation and crept into, and forms the stake holes for Dense Broken Stone Peg 5 of constructing, refers to Fig. 5；
Step 3: tentatively pour into metaling：Metaling is poured into the porch of the drilling rod 1, fills up the metaling
During the inside of the hollow drill, stop pouring into for metaling；
Step 4: lift drilling rod and pour into metaling again：Start the drive device, described in the drive device drives
Drilling rod 1 turns clockwise, and by controlling the drive device drilling rod 1 is at the uniform velocity lifted straight up, in the drilling rod 1
During lifting, the brill door 2 is opened, and makes the metaling continuously into the stake holes formed in step 2；
During the metaling enters the stake holes, when the height of metaling in the hollow drill is less than described
Hollow drill height 1/2~2/3 when, pour into metaling in the porch of the drilling rod 1, the metaling is filled up the sky
The inside of heart drilling rod, refers to Fig. 6；
Step 5: pile body is molded：Repeat step three, until Dense Broken Stone Peg 5 of constructing is molded, refers to Fig. 7 to step 4.
During practice of construction, the drilling rod 1 when being drilled down into and being lifted up the drilling rod 1 be vertical direction, downward
It is the process of pore-forming during drilling, it is ensured that the Dense Broken Stone Peg of shaping is vertical, first has to ensure that formed hole is vertical.
Traditional Dense Broken Stone Peg needs the vibration for being subject to high frequency to drilling rod 1 in pile, and dither can be to stake periphery
Soil produces liquefaction phenomenon, destroys the prototype structure that original-state soil has consolidated, declines bearing capacity of soil, and the present embodiment
In, the drive device drives the drilling rod 1 to be even drilled down into and continuously rotated during being lifted up, without to the brill
Bar 1, which carries out vibration, is drilled down into the drilling rod 1, therefore the disturbance when the drilling rod 1 is drilled down into pile peripheral earth is small, has
Protect, avoided because vibration causes the depression of bearing force of pile peripheral earth beneficial to the prototype structure to pile peripheral earth.
Meanwhile traditional Dense Broken Stone Peg is in formation of pile, because the vibration of high frequency, impact can produce sizable make an uproar
Sound pollutes, and is unfavorable for the protection of ecological environment.
During practice of construction, formation of pile is constructed for soil compaction type, and after pile body shaping, soil around pile compactness is high, and in step 2
Described 1 time drilled as holes of drilling rod is a construction molding, is saved the duration, and without being unearthed in pore forming process, saving construction cost,
The work progress is Jing Yin construction simultaneously, noiseless pollution.
During practice of construction, the external diameter of the drilling rod 1 is determined according to the pile body diameter of construction requirement, in the present embodiment,
The a diameter of φ 300mm~φ 1200mm of pile body after the constructed shaping of Dense Broken Stone Peg 5, the external diameter of the drilling rod 1 is φ 100mm
~φ 800mm.
In the present embodiment, the speed that drilling rod 1 described in step 2 is at the uniform velocity crept into straight down is 0.2m/min~0.5m/
min；
Drilling rod 1 described in step 2 controls the drive device to make the drilling rod 1 per 2m~3m is at the uniform velocity crept into straight down
Stop lower brill, while persistently rotation is not less than 15s to the drilling rod 1；
When being bored described in step 2 at the drilling of door 2 to the stake bottom absolute altitude for Dense Broken Stone Peg 5 of constructing, the driving dress is controlled
Putting makes the drilling rod 1 stop lower brill, while the drilling rod 1 persistently rotates 30s~40s.
In the present embodiment, before the metaling of step 3 pours into, the metaling is processed, the metaling
Particle diameter is not more than the internal diameter of the drilling rod 1.
In the present embodiment, before the metaling of step 3 pours into, the metaling is processed, the metaling
Particle diameter is not more than the internal diameter of the drilling rod 1.
During practice of construction, when the drilling rod 1 is drilled down into, because the soil body of the lower end of drilling rod 1 produces to the brill door 2
Thrust, the brill door 2 closes, and when the drilling rod 1 is lifted up, the brill door 2 is described to open in the presence of metaling gravity
Body 2-1 is closed to open downwards along the mounting rod 2-2, so that metaling can smoothly be fed intake, and without manually entering
Row operation, while when the drilling rod 1 works, the brill door 2 belongs to hidden operation, and people's industry can not operate, therefore use institute
State brill door 2 and effectively solve the problems, such as blanking difficulty.
The speed for controlling the drive device to make the drilling rod 1 at the uniform velocity be lifted straight up in the present embodiment, in step 4
For 0.6m/min~1.2m/min；
After controlling the drive device to make the drilling rod 1 per at the uniform velocity 1m~1.5m is lifted straight up in step 4, control
The drive device makes the at the uniform velocity straight down anti-plug 0.5m~0.8m of drilling rod 1, and after each anti-plug terminates described in control
Drive device makes the drilling rod 1 stop lower brill, while the drilling rod 1 persistently rotates 10s~20s.
During practice of construction, the size for being drilled down into speed, being lifted up speed can be entered respectively according to specific needs
The corresponding adjustment of row.
The drive device is controlled to make the drilling rod 1 is every at the uniform velocity to be lifted straight up during practice of construction, in step 4
After 1m~1.5m, the drive device is controlled to make the at the uniform velocity straight down anti-plug 0.5m~0.8m of drilling rod 1, it is therefore an objective in anti-plug
During, metaling is squeezed again, metaling will be squeezed into inter-pile soil, further improved soil, and by repeatedly being lifted
With squeezing again, metaling is stayed in the hole of shaping, forms the Dense Broken Stone Peg continuously with certain bearing capacity.
It is described above, only it is preferred embodiment of the present utility model, not the utility model is imposed any restrictions, every
Any simple modification, change and the equivalent structure change made according to the utility model technical spirit to above example, still
Belong in the protection domain of technical solutions of the utility model.
