Second soil nailing, arranged for interval are in a row implanted into side slope bottom, and the second soil nailing extends to its front support in lattice
Structure beam side bottom.
Further, the first soil nailing front end is concordant with side slope face, the lattice to rod length to be passed through to pull rod
Structure beam section width+200mm.
Further, the first soil nailing and the second soil nailing are obliquely installed, and tilt angle is 20-30 degree.
Further, the middle part circumferential surface of the first soil nailing middle part and/or the second soil nailing is provided with soil nailing protective layer
Support rod, soil nailing protective layer support rod include annular base plate, convex to form arc surface in the middle part of annular base plate.
Further, the corresponding lattice girder cross-sectional width of the first soil nailing is greater than 300mm and sets less than 500mm by spacing 500mm
It sets to pull rod；It is arranged by spacing 100mm to pull rod when the corresponding lattice girder cross-sectional width of the first soil nailing is less than 300mm.
The utility model is connected using the first soil nailing and carries out lattice beam die plate reinforcing to pull rod, in advance in installation to railing
The formwork sides of position punch, and are reinforced with to pull rod to template.First soil nailing and the whole of side slope is not only increased to pull rod
Body stability, while the template of lattice girder can also be reinforced, the sectional dimension of lattice girder and position.Second soil nailing is used to support lattice
Structure beam forms bottom, further increases the overall stability of form stable and side slope.
Detailed description of the invention
Fig. 1 is high slope lattice girder formwork-strengthening system sectional view described in the utility model.
Fig. 2 is the first soil nailing processing sectional view described in the utility model.
In figure, the first soil nailing of 1-, the second soil nailing of 2-, 3- side slope, 4- is to pull rod, 5- lattice side template, the protection of 6- soil nailing
Layer support rod, 7- lattice girder.
Specific embodiment
A kind of high slope lattice girder formwork-strengthening system that typical embodiment provides of the utility model, including implantation side
First soil nailing 1 and the second soil nailing 2 on slope；First soil nailing 1, arranged for interval are in a row implanted into 3 middle part of side slope, the first soil nailing 1
Front end is fixedly connected with the inner end to pull rod 4；Preformed hole on lattice beam side 5 is passed through to the outer end of pull rod 4, for tensing and propping up
Support lattice beam side 5；Second soil nailing 2, arranged for interval are in a row implanted into 3 bottom of side slope, and the second soil nailing 2 extends to its front end
It is supported in 5 bottom of lattice beam side.
First soil nailing 1 is referred to as short brad, according to embodiment of above, using the connection of the first soil nailing 1 to pull rod 4 into
Row lattice beam die plate reinforcing is punched in formwork sides of the installation to railing position in advance, is reinforced with to pull rod 4 to template.
This short brad and the overall stability that side slope is not only increased to pull rod 4, while the template of lattice girder 7 can also be reinforced, guarantee
The sectional dimension of lattice girder 7 and position.The first soil nailing 1 can also be used as the pull rod of scaffold simultaneously.Second soil nailing 2 is for branch
Lattice beam forms bottom is supportted, form stable is further increased and becomes the overall stability on slope.
Using the reinforcing engineering method, the problem of more than 20 meters or more of irregular tall and big slope retaining difficulty can solve.With biography
The slope retaining of system is compared, and the supporting when excavating, side slope preferable for soil property or the larger tall and big original side slope of height difference are not needed,
It needs supporting that can use and first excavates or first repair slope, then carry out slope retaining.The method can accelerate construction progress, and safety
Reliably.
