Abstract
The utility model discloses a steep towed landslide of face of a thick gliding mass fender protector, including installing in the barricade of landslide bottom, installing in the many root stakes at landslide middle part, installing in the many friction piles on landslide upper portion, barricade, many root stakes, many friction pile lower extremes are all buryyed under the line that slides, many root pile bolck ends pass through linking beam fixed connection, many friction pile tops are through hat roof beam fixed connection. The utility model discloses can ensure once only that the deep gliding mass of steep face is stable, ensure engineering safety, it protects for the normal position, has reached better maintenance treatment effect, and convenient operation, safety, practicality, adopt the normal position mode to solve the technological problem who slides in the steep towed landslide deep of face of current thick gliding mass.
Description
Technical field
This utility model complete gear maintenance field in situ, particularly a kind of thick gliding mass steep face retrogressive landslide props up gear preventer.
Background technology
In recent years, domestic many highways are built and are concentrated on the area, mountain area that structure is complicated, in general, physical features precipitous area in mountain area typically uses overpass to pass through, and overpass construction need to build interim sidewalk, according to the investigation of highway and engineering practice, the slope body caused by interim sidewalk excavation slides of common occurrence on a large scale, this type of landslide typically is provided with following characteristics: complex geologic conditions, slope body has occurred and that deformation of substantially sliding, the huge thick degree of depth of gliding mass is more than 20m, sliding surface and domatic relatively steep gradient are more than 30 °, cut the free face environs that mouth excavates generally within sidewalk, excavation off-load on a large scale does not possess engineering specifications etc..This type of slope body has protected the emphasis paid close attention to into each engineering side.According to tradition big cross section friction pile supporting, there is important potential safety hazard and supporting bad adaptability in stake excavation construction；Potential safety hazard is there is according to off-load+cable bolting, spoir difficulty and spoir transport；According to root pile supporting, its mechanical mechanism is the distinctest, and integral protection potential safety hazard is bigger.
Summary of the invention
Technical problem to be solved in the utility model is, not enough for prior art, it is provided that a kind of thick gliding mass steep face retrogressive landslide props up gear preventer.
For solving above-mentioned technical problem, this utility model be the technical scheme is that a kind of thick gliding mass steep face retrogressive landslide props up gear preventer, including the barricade being installed on bottom landslide, is installed on many root piles in the middle part of landslide, is installed on the many friction piles on top, landslide；Described barricade, many root piles, many friction pile lower ends are all imbedded under the skid wire of landslide；Described many root pile tops connect by linking beam is fixing；Described many friction pile tops connect by Guan Liang is fixing.
Described root pile (2) quantity is 4～6, and many root piles (2) are arranged side by side.
Described friction pile is fixed on to be cut at the gliding mass area of entrance 1/4～1/3 deep away from deep slippage line.
Compared with prior art, the had the beneficial effect that this utility model of this utility model can disposably guarantee that steep deep gliding mass is stable, it is ensured that engineering safety, and it is protection in situ, reach preferable maintenance regulation effect, and easy to operate, safe, practical；Mode in situ is used to solve the technical barrier of existing thick gliding mass steep face retrogressive landslide deep slippage.

Detailed description of the invention
As it is shown in figure 1, this utility model one embodiment includes being installed on the barricade 1 bottom landslide, is installed on many root piles 2 in the middle part of landslide, is installed on the many friction piles 4 on top, landslide；Under the skid wire of embedment landslide, barricade 1 lower end, 1m～2m, many root piles 2, many friction pile 4 lower ends are all imbedded under the skid wire of landslide；Described many root pile 2 tops connect by linking beam 3 is fixing；Described many friction pile 4 tops connect by hat beam 5 is fixing.
In Bridges on Expressways in Mountainous Areas work progress, builder's road excavates the slope body slip unstability caused.The sequence of construction of this complete preventer is antiskid retaining wall 1 bottom first construction, platoon root pile 2 in the middle part of rear construction, finally construction top off-load small bore friction pile 4, bottom antiskid retaining wall 1 is slope body nature triaxial stress state bottom recovery, increasing and cut exit portion gliding mass shearing strength, it is ensured that the gliding mass safety of bottom skid wire and deep slippage line, it ensures the construction safety of root pile simultaneously, bottom antiskid retaining wall 1 by the particle diameter of 40% be not less than 30cm block stone 8 and 60% concrete 9 form, see Fig. 3.Platoon root pile 2 is to ensure that the safety of gliding mass on middle part skid wire and bottom skid wire, it can guarantee that the construction safety of top light section friction pile simultaneously, platoon root pile is made up of 46 single root piles, stake top is connected by linking beam 3, the most single root pile is made up of 3 diameter 32mm reinforcement welding 6 and grout injection 7, sees Fig. 2.Top light section friction pile 4 is to ensure that the safety of gliding mass on top skid wire and bottom skid wire, which reduces sliding force simultaneously, and its position is for cut at the gliding mass area of entrance 1/4 1/3 deep away from deep slippage line.This complete gear preventer excavation is few, can at utmost guarantee construction safety, can effectively protect bottom, middle part, top and deep gliding mass simultaneously and slide.
