Abstract
The utility model relates to an anchoring-bolt for shaft-lining protection, comprising an anchoring bolt with barbs, fastening pieces at the tail end of the anchoring bolt and an anchor plate. The anchoring-bolt for shaft-lining protection has simple structure and convenient operation, and the anchoring-bolt for shaft-lining protection is suitable for various shaft-lining protection in vertically digging construction under various condition.
Description
The utility model relates to a kind of support technology that Tu Bi caves in that in building operations, when underground vertical cut, prevents.What be particularly related to is a kind of bolt support structure.
At present in building deep foundation or basement construction process, new excavation Foundation Design is to underground when digging under vertical, for the unlikely foundation soil on adjacent building basis that causes collapses, or the soil layer that prevents new work plane vertical plane caves in, the technical measures that tradition is taked are generally and beat steel sheet pile, with prefabricated or cast-in-place soil blocking pile, construction diaphragm wall etc.These measures all require its embedded depth to surpass the enough anchorage depths that require cutting depth following, not only consume great deal of steel, cement, and need with large-scale piling machinery or special-purpose heavy construction equipment, especially in the time of will taking the vertical cut situation to local location, urban architecture engineering place or engineering itself when need not pile driving equipment, the more feasible waste of taking above-mentioned measure to be subjected to the restriction of job site and causing an equipment turnover expense.Bolt support and grappling formula retaining structure that the seventies begins one's study and uses generally all need to adopt the rotary impact rig, by becoming 15 °～45 ° to hole on side slope or Tu Bi with level, and then implant reinforcing bar, grout injection; After reinforced earth or the reinforcement anchored bolt retaining wall built, then be when the heap of constructing retaining wall is filled out construction, the dowel layered arrangement process of banketing to be imbedded in the soil.This reinforced anchor bolt suspension device needs to be equipped with rig boring, and the miscellaneous fill that is not suitable for often running into, plain field soil, sand etc. adopt rig boring, the inconvenient soft formation of pore-forming.
The purpose of this utility model is exactly that the level that designs in order to solve the above-mentioned deficiency of existing in prior technology heads into formula bolt support device.
The utility model is made up of anchor slab, the anchor pole that has hangnail and locking member, and anchor slab is contained in the anchor pole tail end by locking member.
Anchor pole fore-end of the present utility model is pointed, is provided with cavity along the anchor pole axis, is provided with the excessive slurry hole that communicates with the anchor pole cavity at anchor pole and hangnail point of attachment.
But anchor pole merogenesis of the present utility model manufacturing, both can guarantee rigidity requirement to anchor pole, be adapted at again constructing in the narrow work plane foundation trench, the front end of the first segment anchor pole that buries is made pointed, the resistance when reducing to head into, and every joint anchor pole can weld or peg graft at the construction field (site), the final section anchor pole can be decided according to the Len req that heads into the soil body, in the end the end of a joint anchor pole is provided with securing member, anchor slab is positioned on the anchor pole and with Tu Bi is adjacent to, and reaches a protective function.Securing member can adopt the weldable steel screw rod, with nut anchor slab is contained on the anchor pole to compress toward native wall direction; Also can be on anchor pole at interval certain distance be provided with and insert Xiao hole, with insert Xiao with on the anchor slab at anchor pole first-class (referring to Fig. 1,3).
Hangnail on the anchor pole can be made into articulated form or is welded on the anchor pole, and its spacing distance is decided on the native wall situation of its supporting.Radial type hangnail anchor pole, behind the precalculated position, pull out a segment distance more outward heading into soil layer with jack, hangnail is opened embed in the soil layer, play the tight effect of anchor, also hangnail can be welded on the hollow anchor bar, and in its connecting portion perforate, in case of necessity can be by hollow anchor bar to soil layer cement injection mortar, cement mortar is infiltrated in the anchor pole soil layer on every side,, strengthen anchored force (referring to Fig. 3) with consolidated earth mass.Anchor pole also can select for use steel concrete to form together with hangnail is prefabricated according to project situation, or selects material such as plastic pipe, bamboo and wood for use.
Anchor slab of the present utility model is one to have the hard plate in hole.Can adopt reinforced concrete prefabricated board to make, perhaps directly utilize the reinforcing bar template on the building site, also can constitute anchor slab at the anchor pole back cast-in-situ steel reinforced concrete on the vertical plane of supporting soil layer that puts in place.Also can adopt the form of an anchor slab of several anchor pole bands during construction.
The utility model is simple in structure, easy to manufacture, easy to use, do not require big job site,, only just anchor pole can be headed in the soil layer yet with simple hydraulic jack without any need for heavy construction equipment and complicated horizontal pore-forming drill, the segment type anchor pole is fit to operate in the foundation trench, also can satisfy the provisional requirement of hole, building site wall supporting, the supporting phase is intact, and anchor pole can be extracted with jack again and use.Particularly when those borings, the soft formation of pore-forming difficulty and foundation ditch dig boulder bed, soil blocking pile is not owing to squeeze into the boulder bed certain depth, and stake does not also possess under the situation such as fixation, just more shows superiority of the present utility model and reliability.
Describe embodiment of the present utility model in detail below in conjunction with accompanying drawing:
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is that the A of Fig. 1 is to partial view.
Fig. 3 is an another kind of structural representation of the present utility model.
Embodiment 1:
As shown in Figure 1, anchor pole 1 usefulness steel pipe merogenesis of the present utility model is made, front end is processed into pointed, suitable distance has groove 2 at interval vertically, the pawl 3 slightly longer than groove 2 is positioned on by bolt 4 and is radial type on the anchor pole, the tail end weldable steel screw rod 5 of anchor pole, anchor slab 6 usefulness precast reinforced concrete plates are made, with on the nut 7 on screw rod.Each saves anchor pole and heads into one weld one again when using.
Embodiment 2:
As shown in Figure 3, anchor pole 8 usefulness steel pipe merogenesis are made, front end is processed into pointed, welding one grout pipe 9 on the tail end section, and keeping at a certain distance away has several slotting Xiao holes 10, the little steel pipe manufacturing of hangnail 11, be welded on the anchor pole, have the slurry hole 12 of overflowing at the position of anchor pole welding hangnail, anchor slab 13 usefulness steel plates are made, on have the hole that matches with anchor pole, with slotting Xiao 14 anchor slab is contained on the anchor pole during use.
Claims (2)
1, a kind of bolt support device of Stabilized Soil wall is characterized in that described bolt support device comprises anchor slab, has the anchor pole and the locking member of hangnail, and anchor slab is contained in the anchor pole tail end by locking member.
2, bolt support device as claimed in claim 1 is characterized in that described anchor pole fore-end is pointed, is provided with cavity along the anchor pole axis, is provided with the excessive slurry hole that communicates with the anchor pole cavity at anchor pole and hangnail point of attachment.
