Become 15 ° of angles between said gathering sill and the gripper shoe, this angle adapts to the occasion of most of construction.
The method of soil nailing wall hole-forming device pore-forming of the present invention may further comprise the steps:
1) mechanical equivalent of light excavation 0.8-1m foundation ditch;
2) base for supporting is placed on the foundation ditch bottom, and supporting leg is squeezed into the foundation ditch bottom, the bottom of supporting bable tops and foundation ditch bottom surface are fitted, and keep the supporting bable tops level;
3) gripper shoe with bracing frame is connected with supporting bable tops with bolt, and the height of the position adjustments stay pipe of pore-forming makes the position height of gathering sill exceed 0.1-0.15m than pore-forming point position height as required;
4) the shovel bar with luoyang spade is placed in the gathering sill, and the operation of beginning pore-forming when luoyang spade driving soil layer 1.9-2m, is extracted luoyang spade, and the speed that luoyang spade is extracted is 1.5-2m/min, after luoyang spade is extracted, removes base for supporting and bracing frame and moves to next setting;
5) on the basis of the foundation ditch of step 1) excavation (be benchmark with former foundation ditch bottom promptly, excavation pit once more also promptly increases the degree of depth of former foundation ditch), repeating step 1)-4), until accomplishing all pore-formings.
Device of the present invention has made things convenient for drilling construction at the unapproachable local location of machinery, has improved the efficient of drilling construction, has guaranteed the quality of pore-forming.
Description of drawings
Below in conjunction with the accompanying drawing and the specific embodiment the present invention is done further detailed explanation.
Accompanying drawing is the structural scheme of mechanism of apparatus of the present invention.
The specific embodiment
Shown in accompanying drawing, soil nailing wall hole-forming device, it comprises:
Luoyang spade 1, said luoyang spade 1 comprise that semi-cylindrical shaped shovel 111 shovels a shovel bar 112 of 111 with being connected.Luoyang spade 1 is the critical component of this device pore-forming.
Base for supporting 2, it comprises the supporting leg 212 that supporting bable tops 211 and supporting bable tops are provided with for 211 times;
Become 10-30 ° of angle between said gathering sill 313 and the gripper shoe 311, the shovel bar 112 of said luoyang spade 1 is placed in the gathering sill 313 and punches.Angle is typically provided to 15 ° between said gathering sill 313 and the gripper shoe 311, and this angle adapts to the occasion of most of construction.
The method step of above-mentioned soil nailing wall hole-forming device pore-forming is following:
1) mechanical equivalent of light excavation 0.8-1m foundation ditch.
The present invention adopts limit pore-forming limit excavation method to carry out successively, until design elevation.Hang down sequential analysis according to the high back of elder generation during operation.
2) base for supporting 2 is placed on the foundation ditch bottom, and supporting leg 212 is squeezed into the foundation ditch bottom, the bottom of supporting bable tops 211 and foundation ditch bottom surface are fitted, and keep supporting bable tops 211 levels.When supporting bable tops 211 was weighed with the error employing angle between the two of horizontal plane, angle between the two should be less than 10 °.
3) the gripper shoe 311 usefulness bolts with bracing frame 3 are connected with supporting bable tops 211, and gripper shoe 311 can be designed to one with supporting bable tops 211, and the purpose of split design is to operate for ease.
The height of the position adjustments stay pipe 312 of pore-forming makes the position height of gathering sill 313 exceed 0.1-0.15m than pore-forming point position height as required.Supporting bable tops 211 can produce error when being placed on the foundation ditch bottom surface, and the 0.1-0.15m that exceeds is in order to eliminate this error.For example, when luoyang spade was worked, base for supporting 2 will inevitably receive the influence of power; This influence can make it break away from original position; Down deeper be absorbed in the foundation ditch bottom, thereby cause the position height of gathering sill 313 and pore-forming point position height to change, cause luoyang spade 1 pore-forming site error.
4) the shovel bar 112 with luoyang spade 1 is placed in the gathering sill 313, and the operation of beginning pore-forming is when luoyang spade 1 driving soil layer 1.9-2m; Extract luoyang spade 1; The speed that luoyang spade 1 is extracted is 1.5-2m/min, after luoyang spade 1 is extracted, removes base for supporting 2 and moves to next setting with bracing frame 3.The speed that luoyang spade 1 is extracted has guaranteed that the Kong Buhui that is become caves in, and can smoothly soil zone be gone out.
5) the inventive method is taked layering, section construction, after accomplishing above-mentioned steps, on the basis of the foundation ditch that step 1) is excavated, (is benchmark with former foundation ditch bottom promptly therefore; Excavation pit once more; Also promptly increase the degree of depth of former foundation ditch), repeating step 1)-4), until accomplishing all pore-formings.
The method is applicable to the position of mechanical hole building inconvenience, and anchor pole and grouting will be synchronized with the mechanical hole building position, so need construction in time, guarantees to accomplish smoothly with the one side work layer.
The foregoing description does not limit the present invention in any way, and every employing is equal to the technical scheme that replacement or the mode of equivalent transformation obtain and all drops in protection scope of the present invention.
