Abstract
The utility model relates to a repeatedly usable expansion type soil nailed wall. The utility model comprises an expansion sleeve (2) which is provided with an expansion seam (1), and the inner diameters of straight pipe sections (3) of the expansion sleeve are the same. The inner diameters with inner screw threads at the anchoring section of the front end of the expansion sleeve are gradually reduced, and after a rod body (7) passes through a tie wall (4), outer screw threads of the rod body (7) are matched with the inner screw threads of the expansion sleeve. A cushion block (5) outside the tie wall and a nut (6) are matched with the rod body, and all structural components of the soil nailed wall can be retracted and used repeatedly. Large funds can be saved, the construction cost is reduced, the supporting effect is ideal and the utility model is suitable for use of temporary support for rocks and soil at the perimeter of a foundation pit during the foundation construction time.
Description
Technical field
The utility model relates to a kind of repeatedly used expansion type soil nailing wall of ground temporary lining engineering.
Background technology
Behind the excavation of building foundation,, need carry out temporary supporting with the soil nailing wall to the ground of foundation ditch periphery in order to prevent the landslide of part or large tracts of land.Most of now method that adopts is to punch in ground, puts into reinforcing bar again and inject cement paste the soil body and reinforcing bar are combined closely.Steel bar end that will stretch out and the steel mesh reinforcement welding that is provided with along metope are filled mud again and are coagulated soil and become the soil nailing wall on steel mesh reinforcement then.These facilities are underground with regard to forever staying behind pit backfill, both caused significant wastage, strengthened construction costs, and efficiency of construction are low, and labor strength is big, also can destroy the facility of periphery sometimes because of punching slip casting, and the environment that pollutes periphery.
The content of utility model
The technical problems to be solved in the utility model is in order to overcome deficiency of the prior art, a kind of construction simple in structure, easy to be provided, to reduce engineering cost and repeatedly used expansion type soil nailing wall.
Technical solution of the present utility model is:
It has an expansion sleeve that has dilatation joint this repeatedly used expansion type soil nailing wall, the inside diameter of straight pipe section of this expansion sleeve is identical, dwindle gradually and expansion sleeve front end anchoring section has the internal diameter of internal thread, the body of rod passes the screw-internal thread fit of its external screw thread and expansion sleeve behind the tie wall.
Further technological improvement of the present utility model is:
Outside tie wall, also have cushion block and nut to cooperate with the body of rod.The said body of rod is a hollow tubular body.
The good effect that the utility model produced is: because the structure that has adopted expansion sleeve to cooperate with body of rod spiral, when the body of rod screws in, the expansion sleeve external diameter expands outwardly gradually, form a back taper wedge-like attitude until closely pushing with ground hole inwall, add the fixing of tie wall and nut, can satisfy the needs of foundation ditch temporary lining all around fully, have suitable supporting intensity, guarantee that ground can not cave in.The expansion sleeve of being made by plastics or nylon is embedded in the ground also not can corrosion, more can not contact for a long time with the body of rod and becomes rusty deadly, uses so can pull out after support engineering is finished again.Use repeatedly after the used expansion sleeve of this soil nailing wall structure, the body of rod, tie wall, cushion block, nut are all detachable, can reduce construction costs greatly.Because of this structure need not to pour in the Xiang Tukong slurry, so there are not any pollution in the soil body and body of groundwater.Do not influence the exploitation and the use on peripheral stratum, economic benefit is fairly obvious.
Description of drawings
Fig. 1: structural representation of the present utility model.
Fig. 2: the view of combining closely with native hole.
The specific embodiment
As shown in Figure 1, the utlity model has an expansion sleeve 2 of making by plastics or nylon material, this expansion sleeve 2 is divided into anchoring section and straight length 3, and its longitudinal length has dilatation joint 1 in the anchoring section upper edge, and straight length 3 is the identical tubular structure of interior external diameter.The internal diameter of anchoring section is dwindled gradually by 3 terminations to anchoring section of straight length, be provided with internal thread at the inner surface of anchoring section, and straight length 3 surfaces externally and internallies is not all established screw thread.Tie wall 4 is the tabular pre-member that concrete or composite material are made, and has the hole that penetrates the body of rod 7 on it.The said body of rod 7 is externally threaded hollow tubular body for outer circumference surface has, and the external screw thread of the body of rod 7 cooperates with the internal thread spiral of anchoring section.For making nut 6 well that the body of rod 7 and tie wall 4 is fastening.Designed one one side and be the plane between nut 6 and tie wall 4 and opposite side is the cushion block 5 on inclined-plane, this inclined-plane should form 90 ° with the body of rod 7.
Fig. 2 shows the end-state of the utility model in native hole.During construction, on ground, get native hole earlier, expansion sleeve 2 integral body are put in the soil inlet hole.Again the body of rod 7 is screwed in anchoring section by straight length 3.Internal diameter dwindles gradually because the external diameter of anchoring section is identical, so the longitudinal cross-section of anchoring section little wedge structure of a big end that is an end, add the effect of dilatation joint 1, anchoring section will outwards strut and combines closely with native hole inwall and be the back taper situation when the body of rod 7 screws in, so expansion sleeve 2 can not pulled out in native hole.Put tie wall 4 and tighten by cushion block 5 and nut 6 this moment on the body of rod 7 promptly become the soil nailing wall.Be provided with so so at interval and can play the temporary lining effect, influence engineering construction to prevent the ground landslide to foundation ditch periphery ground.
When foundation construction finishes and during to pit backfill, but loosen nut 6 sheds cushion block 5 and tie wall 4, screws out the body of rod 7 more gradually, and this moment, expansion sleeve 2 recovered reset condition (referring to Fig. 1) again, can successfully expansion sleeve 2 be pulled out from native hole.Use repeatedly so whole soil nailing wall structure parts are all recoverable, thereby reduce construction costs, save substantial contribution, guarantee programming, reduce labour intensity, can guarantee that also the ground of periphery or body of groundwater are not damaged or pollute.
