Abstract
The present invention is technological scheme of construction process for prestress concrete pile to pass through a medium coarse sand layer, and the construction process features the static pressure construction with a static hydraulic ram machine in the clay layer and fine sand layer and the application of a HF vibration hammer in the medium coarse sand layer. The present invention combines two kinds of construction methods, and has high construction quality, short construction period, low cost and tidy construction site.
Description
Technical field:
The present invention relates to a kind of job practices of prestressed concrete pile.
Background technology:
Static pile press construction prestressed concrete pipe pile penetrates farinose argillic horizon and fine sand layer ratio and is easier to, and passes or to reach certain depth very difficult for medium-sand seam.
Summary of the invention:
The technical problem to be solved in the present invention provides a kind of job practices of prestressed concrete pile, can effectively pass medium-sand seam during construction.Technical scheme: a kind of job practices of prestressed concrete pile is characterized in that: construct with hydraulic static pile pressing machine, when the stake end arrives medium-sand seam, enable high-frequency vibration device.Beneficial effect: when construction silty clay and fine sand layer, use static pressure construction, when constructing medium-sand seam, start high-frequency vibration device and pass, realize combining of two kinds of worker's methods of static pressure and dither, thereby guarantee construction quality, reduction of erection time reduces cost, and is on-the-spot clean and tidy.
Description of drawings:
The high-frequency vibration device structural representation of Fig. 1 for installing on the hydraulic static pile pressing machine;
Fig. 2 is the vibrating bin structural representation.
The specific embodiment:
With hydraulic static pile pressing machine silty clay and fine sand layer are constructed, when the stake end arrives medium-sand seam, enable high-frequency vibration device, high-frequency vibration device can be high-frequency vibratory hammer, as shown in Figure 1, high-frequency vibration device can also be vibrating bin 2, and pile clamping box 1 below of vibrating bin and hydraulic static pile pressing machine is fixed.As shown in Figure 2, vibrating bin is provided with two motors 7,10, and the gear 8,9 that is provided with in the vibrating bin on 3,6, two motor output shafts of two eccentric shafts is meshing with each other, gear 4,5 is housed respectively on two eccentric shafts, and the gear 8,9 on gear 4,5 and the motor output shaft meshes respectively.Motor can drive two eccentric shaft rotations and keep horizontal reverse sync and vertically synchronous in the same way, and the horizontal centrifugal force of diaxon is cancelled out each other, and vertical centrifugal force mutual superposition drives vibrating bin extensional vibration.
During work, before arriving medium-sand seam, only both can finish with normal pile pressing method.When arriving medium-sand seam, the primer fluid pressure device is to the hydraulic motor fuel feeding of vibrating bin, make vibrating bin produce dither, driving pile body by pile clamping box vibrates together, make between stake and the sand and produce liquefaction phenomenon, side grinding resistance reduces greatly, end support power also along with in, the destruction of original packed structures of coarse sand and reducing greatly.The pile clamping box of dither can form 150 tons exciting force, stake is squeezed into gradually and passes medium-sand seam.
Claims (4)
1. the job practices of a prestressed concrete pile is characterized in that: construct with hydraulic static pile pressing machine, when the stake end arrives medium-sand seam, enable high-frequency vibration device.
2. the job practices of prestressed concrete pile according to claim 1, it is characterized in that: high-frequency vibration device can be arranged in the vibrating bin, and the pile clamping box of vibrating bin and hydraulic static pile pressing machine below is fixing.
3. the job practices of prestressed concrete pile according to claim 2, it is characterized in that: vibrating bin is provided with motor, be provided with two eccentric shafts in the vibrating bin, on two eccentric shafts gear be housed respectively, the gears engaged on aforesaid gear and the motor output shaft.
4. the job practices of prestressed concrete pile according to claim 1, it is characterized in that: high-frequency vibration device can also be high-frequency vibratory hammer.
