Stake, each described stake is inserted side slope before every layer of earth excavation vertically downward, described side slope is arranged at intervals with horizontal and vertical
The most equally spaced multiple soil nailing, each described soil nailing inserts side slope, described stake and described soil nailing on limit after every layer of earth excavation
Interlaced arrangement on slope, described stake is log pile, and described soil nailing inserts side slope the most obliquely, the incline direction of soil nailing
Contrary with the incline direction of side slope, described soil nailing is horizontal by 10 °～25 ° of angles.
Further, described side slope is inserted with at least one tapping pipe.
Further, described side slope is covered with net spray plane layer.
Further, described net spray plane layer is bar-mat reinforcement.
Further, described net spray plane layer is covered with concrete layer.
Further, top, slope and the toe of described side slope is equipped with gutter.
Further, reversely incline relative to side slope in the ground connecting place between the gutter on described side slope and top, slope
Tiltedly.
Further, a length of 6m of described log pile, a diameter of 200mm of described log pile.
This utility model has the advantage that as follows: this utility model utilizes stake, before slope excavating, the soil body has been carried out bank protection
Process, it is ensured that before every layer of earth excavation, exist for supporting construction, and then use less slope ratio to carry out putting slope excavation, in the earthwork
Soil nailing of constructing after excavation is further ensured that the stability of side slope, solves Unfavorable geology foundation ditch and puts local side slope in the digging process of slope
Destabilization problems, adds the slope stability of layered soil in Excavation Process.It has, and design is simple, it is convenient to construct, guarantor
The advantages such as card side slope safety, and use the foundation ditch field putting slope excavation to have preferable application prospect at Unfavorable geology.

Detailed description of the invention
Describe performance of the present utility model below in conjunction with the accompanying drawings in detail, but it is not intended that limit of the present utility model
Fixed, only illustrate.Simultaneously by explanation, advantage of the present utility model will become clearer from easy to understand.
As shown in Figure 1: a kind of Unfavorable geology foundation ditch that is used for puts slope excavation combined bearing structure, including side slope 6, side slope 6
On be arranged at intervals with the most equally spaced horizontal and vertical multiple stakes, side slope is inserted in each stake before every layer of earth excavation vertically downward
6, side slope 6 is arranged at intervals with the most equally spaced horizontal and vertical multiple soil nailings 3, each described soil nailing 3 is at every layer of earth excavation
Rear insertion side slope 6, described stake and described soil nailing 3 interlaced arrangement in side slope 6.In the present embodiment, described stake is log pile 4,
The most equally spaced horizontal and vertical four row's log piles 4 it are arranged at intervals with in side slope 6, a length of 6m of log pile 4, log pile 4
A diameter of 200mm, in actual mechanical process, can carry out spreading process according to field condition to log pile.
As shown in Figure 1: four row's log piles 4 are respectively in ground floor earthwork top mark height B, second layer earthwork top mark height C, third layer
Side slope 6 is inserted vertically downward before earth excavation, it is ensured that open every layer of earthwork at earthwork top mark height D and the 4th layer of earthwork top mark height E
