Detailed description of the invention
With embodiment, this utility model is described further below in conjunction with the accompanying drawings:
Embodiment 1: as shown in Fig. 1 ~ 3, a kind of core stake guider being applicable to cement slotting built pile, it includes position
In core stake about 1 two ends and the armored concrete guide pad group that is evenly arranged along core stake 1 circumferential exterior surface, armored concrete guides
Block group is fixed together with core stake 1;The maximum outline diameter of core stake 1 of armored concrete guide pad group is installed equal to water
Earth stake diameter.Described armored concrete guide pad group is made up of at least three armored concrete guide pad 2, armored concrete
Guide pad 2 is the block by concrete poured up at a time, and inside is equipped with framework of steel reinforcement increases its globality.Reinforced concrete
Soil guide pad 2 includes bottom surface, end face, interior facade, alien invasion, two side elevations, and interior facade is suitable with core stake outer surface, alien invasion
Including a vertical plane and the inclined-plane that has angle with armored concrete guide pad 2 bottom surface.
As it is shown on figure 3, the width of armored concrete guide pad 2 (the long limit of radial direction of end face) is by cement earth pile stake footpath and core
The relativeness of stake sectional dimension determines, makes the core stake maximum outline diameter being provided with armored concrete guide pad group equal to water
Earth stake diameter;The depth-width ratio of armored concrete guide pad 2 is 2, the width of armored concrete guide pad 2 and thickness
Ratio be 2, i.e. the height of armored concrete guide pad 2 is 4 with the ratio of thickness;Inclined-plane in alien invasion guides with armored concrete
The angle of block 2 bottom surface is 120 °.The size relativeness of armored concrete guide pad 2 is ensureing the same of self enough bulk strength
Time, the resistance making again armored concrete guide pad group importing cement earth pile is less, it is possible to imports in cement earth pile smoothly and ensures to lead
To effect.
Armored concrete guide pad 2 can use multiple connected mode with the connection of core stake 1: (1) is at pouring reinforcement coagulation
During soil guide pad 2, built-in metal pipe in armored concrete guide pad about 2 position, steel wire passes through after built-in metal pipe
Buckle for locking wire, take out compact form wire closure, the mode of U-shape lock realizes end to end and armored concrete guide pad 2 and core stake 1 is fastened on
Together;(2) when pouring reinforcement concrete guide pad 2, prepared screw-bolt hole on armored concrete guide pad 2, simultaneously in core stake 1
Upper boring, is fixed on armored concrete guide pad 2 in core stake 1 by expansion bolt.
Embodiment 2: the present embodiment part same as in Example 1 repeats no more, difference is that it is that a kind of core stake is led
To method, it uses the core stake guider being applicable to cement slotting built pile of 1 in embodiment, and it comprises the steps:
Before core stake 1 is inserted after cement earth pile has been constructed, armored concrete guide pad 2 is fixed on core stake 1 lower end;Treat core stake
Before the 1 fully-inserted cement earth pile in upper end, by another group armored concrete guide pad 2 be fixed near core stake 1 upper end, after by core
Stake 1 is sent to designed elevation, realizes the core stake 1 guide effect in soil cement with this.
Embodiment 3: as shown in figs. 4-7, a kind of core stake guider being applicable to cement slotting built pile, it includes position
In core stake about 1 two ends and along core stake circumferential exterior surface arrange slip casting rubber bag tank, slip casting rubber bag tank is fixedly connected on core stake 1
Together;The maximum outline diameter of core stake 1 of slip casting rubber bag tank is installed equal to cement earth pile diameter.Described slip casting rubber bag tank is permissible
Pressed from both sides the materials such as screen cloth with PVC terylene composite, rubber with TPU by rubber be made with high strength fibre cloth, rubber, be city
Matured product in Chang, concrete size can customize according to requirement of engineering.
Rubber bag tank 4 that slip casting rubber bag tank includes circular hollow and the Grouting Pipe 5 connected with rubber bag tank;Rubber bag tank 4 is near core
Stake 1 side has twice to pierce one's ears 6 for wear steel wire 3;After slip casting, rubber bag tank 4 is ring-type, is fixed on by steel wire 6 colligations of piercing one's ears
Core stake 1 two ends.
Embodiment 4: the present embodiment part same as in Example 3 repeats no more, difference is that it is that a kind of core stake is led
To method, it uses the core stake guider being applicable to cement slotting built pile of 3 in embodiment, and it comprises the steps:
Before core stake 1 is inserted after cement earth pile has been constructed, by rubber bag tank 4 by steel wire rope colligation at core stake 1 lower end, treat core stake
Before the 1 fully-inserted cement earth pile in upper end, another rubber bag tank 4 is fixed near core stake upper end by steel wire 3 colligation, by core
After stake is completely forced in cement earth pile, injects cement mortar by Grouting Pipe and make the increase of rubber bag tank 4 volume be close to undisturbed soil hole wall,
The core stake 1 guide effect in soil cement is realized with this.
It addition, core stake 2 can include hollow preformed pile, solid prefabricated pile, shaped steel etc., it is only necessary to follow change armored concrete and lead
To block 2, the size of slip casting rubber bag tank 4, the principle of number, this device just can be applied to realize the guiding in different cement earth piles.
