Technical field
The utility model relates to that civil engineering, bridge room are built, self-balancing root key castinplace pile thrustor in the hydro-structure.
Background technology
Traditional pile foundation mainly contains placing stake on the spot, sinks to stake, bores (digging) hole stake, preformed pile base form.So that placing stake application is comparatively general on the spot, still, part comes with some shortcomings in engineering.Hand excavated pile is the castinplace pile that carries out the supporting while excavating for better stratum.Because can the hand excavation and that underground geological conditions is better held its pile is reliable, but for soft stratum or the stratum of easily collapsing, the stake that the degree of depth is bigger be inadvisable.
Tube-sinking cast-in-situ pile is to use minor diameter immersed tube machinery to sink to predetermined back, stratum and carries the piling method that the tube edge cast is vibrated.Bored pile and tube-sinking cast-in-situ pile mechanism are similar, current, and bored pile is often made major diameter (above 3 meters) for reaching requirement for bearing capacity, and super long pile (greater than 50 meters) is used less economical on the engineering.Root key castinplace pile is a kind of bionical basis that forms at prefabricated key of castinplace pile sidewall jacking clocklike, can improve the bearer properties and the stock utilization on basis preferably.
Summary of the invention
In order to solve the incremental launching construction problem of the less root key castinplace pile of diameter, the utility model provides a kind of minor diameter self-balancing root key castinplace pile root key thrustor.
Concrete structural design scheme is as follows:
Minor diameter self-balancing root key castinplace pile root key thrustor comprises horizontally disposed roof pressure reaction frame, the roof pressure reaction frame is provided with jack in the middle of the bottom, the uniform connecting rod that is connecting more than two of its bottom outside, the lower end of connecting rod is connecting to descend reaction plate, be provided with the cross sliding clock groove between the reaction plate under adjacent, be provided with slide block in the cross sliding clock groove; The compression bar of jack is connecting the big end middle part of the squeezed head of back taper, and the small end correspondence of the squeezed head of back taper slide block.
Described roof pressure reaction frame bottom outside is uniform to connect four connecting rods, and the cross section of four connecting rods is matrix pattern and arranges.
The cross section of the squeezed head of described back taper is cross, is positioned at cross section and is four connecting rod spaces that matrix pattern is arranged.
Described slide block slot corresponding both faces is respectively equipped with groove, and described slide block both sides are respectively equipped with projection, and the projection correspondence is positioned at groove.
Useful technique effect of the present utility model is embodied in several aspects:
1, this device is well optimized smaller diameter root key (below 3 meters) bored pile construction, adopts reinforcing cage structure guiding skeleton and utilizes the reliable jacking root of self-balancing jack root key jacking mechanism key, has solved the installation in position problem of root key.
2, the self-balancing type jacking mechanism of this device has been avoided the powerful counterforce device of the required external device (ED) of jacking root key, and horizontal concrete chute has guaranteed the accurate installing and locating of root key simultaneously.
3, this device can be provided with root key box and inner root key lifting appliance in the jacking mechanism lower end, by the jacking efficient that improves the root key that is provided with of " cartridge-type ".
4, the utility model uses the vibration of root key static pressure to put in place, fluid concrete became the anchorage node of root key after the root key of reinforcing bar guiding internal frame put in place, make node reliable and stable, utilize the soil body that the bond stress of root key has been increased stability of structure, alleviate dead load greatly, thereby had better economy.
5, adopting the job practices of these the complete sets of equipment is the root key construction process of bored concrete pile of self-balancing type, root key static pressure operation work efficiency height wherein, good reliability.

The specific embodiment
Below in conjunction with accompanying drawing, the utility model is further described by embodiment.
Embodiment:
Referring to Fig. 1 and Fig. 2, minor diameter self-balancing root key castinplace pile root key thrustor comprises the jacking mechanism reaction frame, the jacking mechanism reaction frame comprises reaction plate 7 and four connecting rods 9, jack 2 is installed in the middle of last reaction plate 7 bottoms, the uniform cross section that is connecting 9, four connecting rods 9 of four connecting rods of its bottom outside is matrix pattern and arranges; The lower end of every connecting rod 9 is connecting to descend reaction plate 8, is provided with cross sliding clock groove 6 between the adjacent following reaction plate 8, is provided with slide block 4 in the cross sliding clock groove 6, sees Fig. 3 and Fig. 4; The compression bar 11 of jack 2 is connecting the big end middle part of squeezed 3 of back taper, and the small end correspondence that back taper is squeezed 3 slide block 4.
The cross section that back taper is squeezed 3 is cross, is positioned at the space that cross section is four connecting rods 9 that matrix pattern arranges, and sees Fig. 5 and Fig. 6.
Concrete use operating procedure of the present utility model is such:
