Step 4, anchor position is demarcated in the plane that step 3 is formed, demarcated with the plane vertical direction Anchor position on drill, mortar is poured into the drilling, and the anchor is fixed in the drilling.
Wherein, the anchor includes the hollow body of rod 1, chock 2 and pressure ram 3, and one end of the body of rod 1 is point End, another end opening, and by it is described drilling stretch into it is described it is domatic in, internal thread, the bar are provided with the inwall of the body of rod 1 First opening is set in the side wall of body 1, and the chock 2 is arranged to first end as tip, and the second end has outwardly cambered surface Cone, and be arranged in a manner of tip is towards the outer wall of the body of rod 1 in the described first opening, and the chock 2 Length is not more than the 1/2 of the external diameter of the body of rod 1, has space between the outer wall of the chock 2 and the described first inwall being open;Institute State and the second opening 4 is provided with around the first opening;The outer wall of the pressure ram 3 is provided with the outer spiral shell with the screw-internal thread fit Line, the first end of the pressure ram 3 is tip, and the external diameter of the pressure ram 3 is engaged with the internal diameter of the body of rod 1, so that When the pressure ram 3 screws in the body of rod 1, the chock 2 is extruded, and the tip of the chock 2 is protruded the body of rod 1 Outer wall.
Step 5, stake holes is drilled out by design requirement, and steel pile casting is installed in stake holes, the steel pile casting is both ends open Hollow cylinder structure, and the diameter of the steel pile casting is gradually increased by stake holes bottom to stake holes surface, the side wall of the steel pile casting On open up multiple slurry leakage holes.
Step 6, steel reinforcement cage with its minor diameter fit is put into the steel pile casting, and coagulation is irrigated in the steel reinforcement cage Soil, form pile body.
Step 7, cushion cap is made above pile body, forms pile foundation.
In such scheme, by installing steel pile casting in stake holes, and steel reinforcement cage is installed in steel pile casting, steel pile casting is to stake Hole surface plays a part of fixed and supported, and steel reinforcement cage can reinforce the pile body that follow-up concrete is formed, by setting steel to protect Cylinder is to have stake holes bottom to stake holes surface gradually to increase so that the simpler convenience of installing of steel pile casting, so as to reduce construction Difficulty, speed of application is improved, by opening up multiple slurry leakage holes in the side wall of steel pile casting so that by the coagulation irrigated in steel reinforcement cage Soil can enter steel pile casting through steel reinforcement cage, and be entered by the slurry leakage hole of steel pile casting in stake holes so that stake holes, steel pile casting and reinforcing bar Cage closely bonds together, and then further increases the steadiness of pile foundation construction, avoids the leakage of pile foundation summit portion Or to face slope country rock thickness excessively thin, cause effective length insufficient, the hidden danger of quality such as bearing capacity weakens.
As shown in Fig. 2 in a preferred scheme, the linked network includes outer net 5 and the Intranet 6 being set in the outer net 5, The wirerope that the grid of the outer net 5 is interlocked by transverse and longitudinal is worked out, and horizontal wirerope and longitudinal wirerope are respectively set to two, and institute The position for stating horizontal wirerope and the contact of longitudinal wirerope is mutually overlapped, and the Intranet 6 is made up of the steel wire being arranged in the grid, And the mesh of the Intranet 6 is 2-5 mesh.
In such scheme, by setting the linked network collectively constituted by outer net and Intranet, outer net is worked out by the wirerope of two-wire Form, can significantly strengthen the intensity of linked network, and by setting the Intranet of steel wire composition, Intranet mesh inside the grid of outer net Only 2-5 mesh, can effectively fix abrupt slope it is domatic on rubble etc., and the setting for passing through linked network so that cement sand bed with Domatic is completely embedded.
In one preferred scheme, the position that the horizontal wirerope and longitudinal wirerope are in contact is articulated in.
In such scheme, the position that horizontal wirerope and longitudinal wirerope are in contact is articulated in, does not interfere with linked network Structural strength, and make it that the mounting of anchor pole and linked network is firmer, so as to play good fixed effect to linked network.
In one preferred scheme, the mortar amount poured into the drilling is to the 1/3-1/2 of the drilling depth.
In such scheme, by limiting 1/3-1/2 of the mortar amount poured into drilling as drilling depth so that the body of rod is stretched Enter in drilling, will not to emit outside mortar, so as to influence normal construction, and the mortar amount of 1/3-1/2 drilling depths is also enough to make Obtain mortar and how domatic inside is penetrated into by each second opening on the body of rod.
In one preferred scheme, the pressure ram 3 pours into after cement mortar in the opening by the body of rod 1 and screws in the bar Body 1.
In such scheme, cement mortar is poured into the body of rod, it is identical with pouring into cement mortar effect in anchor pole, it can make The body of rod is obtained preferably to link together with domatic by the sticky of cement mortar.Meanwhile by setting pressure ram and the body of rod to pass through The mode of screw thread rotation is in contact so that pressure ram stretches into more laborsaving convenience in the body of rod, so as to effectively reduce constructor The working strength of member, improves efficiency of construction, that is, reduces construction cost.
In one preferred scheme, the pressure ram 3 is after the body of rod 1 is completely screwed into, then reversely screws out the body of rod 1, To reuse.
In such scheme, by the way that pressure ram is screwed in the body of rod, chock can be extruded and cement mortar is stretched into outside the body of rod Portion it is domatic in, so as to improve anchor to domatic fixed effect, and after pressure rod is screwed out, pressure ram can be made repeatedly Use, so as to reduce cost, in addition, cement mortar can be poured into the body of rod after pressure ram back-out, will be filled out inside the body of rod It is full, so as to further increase the deadweight of the body of rod, also just improve anchoring effect.
In one preferred scheme, the second end of the pressure ram 3 is the cambered surface to the concave end of pressure ram 3 first, institute State the groove 19 that right-angled intersection is offered in cambered surface.
In such scheme, by the second end of pressure ram set concave surface, and above set right-angled intersection groove, By specific purpose tool or other instruments pressure ram can be more easy to inside the convenient and strength-saving screw-in body of rod, and then reduce construction The work difficulty of personnel.
Although embodiment of the present invention is disclosed as above, it is not restricted in specification and embodiment listed With it can be applied to various suitable the field of the invention completely, can be easily for those skilled in the art Other modification is realized, therefore under the universal limited without departing substantially from claim and equivalency range, it is of the invention and unlimited In specific details and the legend herein shown with description.
