Above-mentioned pull rope is provided with many groups at interval, and every group is 2, is separately fixed on the different earth anchors, and the angle of two pull rope formation is less than or equal to 60 degree.
Above-mentioned body of wall connects horizontal bar and ties up weldering by two steel pipes up and down and form.
Above-mentioned earth anchor length is 1.5-2.0m.
Technique effect below the utility model has been obtained:
The rigid protection that the utility model provides keeps off native curtain wall; Adopt field Welding and colligation; It is easy for installation flexible to suit measures to local conditions, and body of wall connects horizontal bar and Bamboo strip plate is mated formation through being provided with, and can increase the lifting surface area that rigidity is kept off native curtain wall; Avoid local pressure to concentrate, and can prevent that the gravelly soil slag from passing the native curtain wall of retaining; Adopt the support fixation mode of " shore in interior side-lining, the outside, earth anchor anchoring ", the body of wall secure, anti-impact force is strong; And most of mounting material can repeatedly change tears repeated use open; When effectively improving safety, environmental-protection effect, also reduce construction cost, accelerated construction speed.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is described further.
Fig. 1 is the front view of the utility model apparatus structure;
Fig. 2 is the lateral view of Fig. 1.
The specific embodiment
A kind of rigid protection keeps off native curtain wall shown in Fig. 1-2; It is included in the many rows earth anchor 7 that is provided with from bottom to up on the side slope 10, descends most and vertically is installed with rigid cage 1 on row's earth anchor, and the rigid cage outside is provided with overcoat 2; Be provided with cushion pad 8 between side slope and the overcoat; The rigid cage inboard is provided with up and down two-layer body of wall and connects horizontal bar 6, is provided with drawing pull bar 5 between lower floor's body of wall connection horizontal bar and the earth anchor, is provided with pull rope 4 between upper strata body of wall connection horizontal muscle and the earth anchor; Lower floor body of wall connection horizontal bar bottom is provided with vertically shores 9, and body of wall connection horizontal muscle bottom, upper strata is provided with diagonal brace 3.
Preferably, described pull rope is provided with many groups at interval, and every group is 2, is separately fixed on the different earth anchors, and the angle of two pull rope formation is less than or equal to 60 degree.Described body of wall connects horizontal bar and ties up weldering by two steel pipes up and down and form.Described earth anchor length is 1.5-2.0m.
The implementation step of the utility model is following:
1, φ 38 round steel of imbedding long 1.5～2.0m after the boring of employing hammer drill are as earth anchor 7 joint bars, convenient and quick construction;
2, on earth anchor 7 joint bar φ 38mm round steel, weld I20b, height 6.0m forms the vertical rigid support of keeping off native curtain wall; Adopt I18a that the I20b bottom is welded into a whole; Adopt φ 22mm rebar spacing 0.25m that vertical rigid support is welded into integral body, form rigid cage 1;
3, with Bamboo strip plate adopt φ 22mm reinforcing bar tie up bar (spacing 2.0m) divide 1～3 layer mat formation, colligation is inboard in rigid cage, forms overcoat 2, local colligation tire is as buffering;
