Construction, and make surrounding environment without prejudice and the engineering measure of the structural support of use, Groundwater Control etc..And soil nailing branch
Shield is a kind of new earth-retaining technology for soil excavation and stability of slope, because economic, reliable and construction is fast and convenient, is existed
China obtains rapid promotion and application.Plate brad supporting has turned into the branch of another item more maturation after stake, wall, support, anchor supporting
Shield technology, it has, and speed of application is fast, construction equipment is light, operating method is simple, to place strong adaptability, safe and reliable, warp
The advantages that Ji.
Chinese patent such as Publication No. CN204491632U discloses a kind of side slope fixing device, including side slope body,
Wire netting, bearing plate, nut, screw rod, soil nailing body, cement and pad；The side slope body surface is equipped with wire netting, described
Side slope body interior is placed with soil nailing body, and the side slope body interior soil nailing body surrounding is inoculated with cement, side slope body exterior
Soil nailing body is fixedly connected with bearing plate, and the pressure-bearing plate surface is fixed with the nut and screw rod connected by screw-internal thread fit,
The screw rod end is fixed on pressure-bearing plate surface.
Program side slope body by the way of soil nailing fixation is fixed, and passes through soil nailing, cement, supporting plate and iron wire
Net etc. coordinates carries out Dam Foundation Strengthened in Situ by a range of soil body, can effectively reduce the stress that side slope is brought because excavation faces sky and release
Put, side slope is kept original rock-steady structure, avoid caving in, but the soil nailing ailhead is spirally connected fastening by nut, and nut is in soil nailing
Fixation is not firm enough in supporting construction, is easily loosened under the pressure of soil layer, influences the firmness of soil nail wall, certain safety be present
Hidden danger.
Utility model content
In view of the deficienciess of the prior art, the purpose of this utility model is to provide a kind of soil nailed wall retaining structure, the soil
Nut in nail wall supporting construction will not loosen, ensure the firmness of supporting construction easily.
Above-mentioned technical purpose of the present utility model technical scheme is that：
A kind of soil nailed wall retaining structure, including excavation slope, the excavation slope side wall are drilled with some rows and stretch into foundation ditch side
Hole in slope, soil nailing has been pierced in hole, the soil nailing outer filling has concrete, and the excavation slope side wall is covered with reinforced concrete
Soil layer, reinforced concrete floor are provided with bearing plate outside, and one end end of the soil nailing is in outside reinforced concrete floor and end is set
There is screw thread, soil nailing end is fixedly linked by the first nut with bearing plate, is also set between the bearing plate and reinforced concrete floor
Pedestal is equipped with, the soil nailing surrounding is provided with some anchor poles for sequentially passing through bearing plate, pedestal and reinforced concrete floor, anchor pole end
Portion is provided with screw thread, and anchor pole end is fixedly linked by the second nut with bearing plate, and spring, spring two are socketed with the anchor pole
End is between bearing plate and pedestal and spring is in compressive state.
Using said structure, anchor pole can assist the common side slope of soil nailing to be fixed, and the setting of multiple second nuts can have
The stress of scattered first nut of effect, while be socketed in anchor pole and cause the first spiral shell in the spring compressed between bearing plate and pedestal
It is female that there is stronger shockproof anti-loose ability with the second nut, so that the nut in the soil nailed wall retaining structure will not be sent out easily
The raw firmness for loosening, ensureing supporting construction.
It is further arranged to the pedestal and is arranged with supporting platform seat and the supporting table being fixedly connected with reinforced concrete floor.
Using said structure, the setting of supporting table can effectively play the enabling capabilities to pedestal, disperse soil nailing and anchor pole pair
The stress of pedestal, ensure the stability of strutting system of pedestal.
It is triangle to be further arranged to the supporting table side.
Using said structure, triangle has stronger stability, and the stable of pedestal is supported so as to play.
It is further arranged to the excavation slope and side slope side wall in the vertical direction is provided with water-stop curtain, the soil
Follow closely through water-stop curtain.
Using said structure, the setting of water-stop curtain can ensure the soil solidifying between excavation slope and water-stop curtain, resistance
Water layer exchange inside and outside disconnected foundation ditch, is easy to the construction of soil nailing, while further enhance the fastening strength to excavation slope.
It is self-locking nut to be further arranged to first nut and the second nut.
Using said structure, the setting of self-locking nut can further reduce nut from loose rate, ensure the first nut and the
Two nuts are to soil nailing and the lock ability of anchor pole.
In summary, the utility model has the advantages that：
1. pass through the setting of spring and self-locking nut so that pine will not occur easily for the nut in the soil nailed wall retaining structure
Firmness that is dynamic, ensureing supporting construction；
2. the setting of water-stop curtain can ensure the soil solidifying between excavation slope and water-stop curtain, block inside and outside foundation ditch
Water layer exchanges, and further enhances the fastening strength to excavation slope.
