Description
Technical field
The utility model relates to Hydraulic and Hydro-Power Engineering and similar engineering field, particularly relates to a kind of gear protection structure for levelling of the land.
Background technology
At present, the construction work carried out at high-mountain gorge areas gets more and more, and by the influence of topography, there is a serious shortage in the supply in construction plant, in order to meet the construction needs of engineering, has to carry out large-scale levelling of the land.The gear of current levelling of the land protects the traditional retaining wall of main employing, comprises and grouting or placed rockfill bank protection, cast-in-situ concrete bank protection, precast concrete block bank protection etc.Its intensity effect only emphasized by this type of retaining wall, but restricts by height and the factor such as bearing capacity of foundation soil, can smooth go out site area less, and construction investment is larger.On the other hand, this type of retaining wall ecological performance is poor, is unfavorable for the ecological protection around Hydraulic and Hydro-Power Engineering.
In order to solve foundation condition difference better, large-area construction place that side slope is high props up gear problem, and considers the factor of construction investment, needs research can adapt to the smooth gear protection structure in soft base, highly large place.
Utility model content
High to ground requirement for bearing capacity for overcoming existing retaining wall, the high deficiency of construction cost, technical problem to be solved in the utility model is: provide the gear protection structure that a kind of construction cost is low, adapt to the strong levelling of the land of foundation deformation ability.
The utility model solves the technical scheme that its technical problem adopts: for the gear protection structure of levelling of the land, comprise the body of wall be made up of geo-grid and the native hardcore layer between geo-grid, the vertically layering of described geo-grid is laid, described native hardcore layer is filled and is pressed between geo-grid, every layer of geo-grid at the metope place of body of wall all upwards anti-package form a turn-up section, described turn-up section encases one deck soil hardcore layer and links together with last layer geo-grid.
Further, turn-up section and the last layer geo-grid of described geo-grid are connected together by pitman, and described pitman interts between cross one another grid.
Further, described geo-grid is unidirectional grid, and it is consistent that the direction pointing to metope carried on the back by the length direction of the mesh of described unidirectional grid and the wall of body of wall.
Further, crushed rock filler layer is provided with in the substrate of body of wall and wall back.
Further, in the metope position of body of wall and the turn-up section of geo-grid, be provided with the grid anti-package body be paved into by the ecology bag filling soil.
The beneficial effects of the utility model are: the gear protection structure adopting geo-grid and native hardcore to be formed belongs to flexible structure, and every layer of geo-grid all links together, improve the stability of whole body of wall, adapt to foundation deformation ability strong, can be used for slope coefficient greatly, highly high levelling of the land, construction method is simpler compared with traditional retaining wall, and cost of investment is lower.

Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is further illustrated.
As shown in Figure 1, profile of the present utility model and traditional retaining wall similar, the body of wall of traditional retaining wall is mainly formed by the concrete of building or prefabricated concrete masonry.Body of wall of the present utility model 1 is mainly made up of geo-grid 2 and the native hardcore layer 3 between geo-grid 2, the vertically layering of described geo-grid 2 is laid, described native hardcore layer 3 is filled and is pressed between geo-grid 2, every layer of geo-grid 2 at metope 11 place of body of wall 1 all upwards anti-package form a turn-up section 21, described turn-up section 21 encases one deck soil hardcore layer 3 and links together with last layer geo-grid 2.Major part retaining wall mainly bears the water and soil thrust from the pressure on wall top 13 and the wall back of the body 12, and the pressure that wall top 13 can be born is determined by the anti-pressure ability of body of wall 1 material own, and the water and soil thrust of carrying on the back 12 from wall is then mostly kept out by the deadweight of body of wall 1.
What body of wall 1 of the present utility model mainly adopted is native stone, can add the sticking clay of band in described native stone.The soil body has certain anti-pressure ability, can bear the pressure from longitudinal direction, but the shear strength of the soil body is very poor, can not bear the water and soil thrust from the wall back of the body 12, therefore add in the soil body and have more high-tensile geo-grid 2.Geo-grid 2 is embedded in the soil body, the stress of the soil body can not only be spread, increase modulus, can also transmit tensile stress, the lateral deformation of the restriction soil body, increases frictional resistance between the two, therefore improve the stability of the whole soil body, the water and soil thrust from the wall back of the body 12 can be born.Relative to traditional concrete wall, body of wall 1 of the present utility model is flexible structure, less demanding to ground, when ground changes, traditional concrete wall easily collapses or occurs crack, the utility model then can the change of adaptation to the ground under the effect of geo-grid 2, there will not be the problems referred to above.
Further, as shown in Figure 2, in order to make work progress succinct more fast, connected together by pitman 4 in turn-up section 21 and the equitant part of last layer geo-grid 2 of described geo-grid 2, described pitman 4 interts between cross one another grid.This connected mode is simple to operate, and it is firm to connect, and allows there is certain displacement between the two, and more improve the flexibility of body of wall 1, adaptation to the ground ability is stronger.Because body of wall 1 mainly bears the water and soil thrust from the wall back of the body 12, so adopt unidirectional geo-grid, unidirectional geo-grid can bear larger tensile stress, and the length direction of the mesh in unidirectional geo-grid and the wall of body of wall 1 are carried on the back 12 to point to the direction of metope 11 consistent.
In order to prevent the immersion in massif from having an impact to body of wall 1, the special substrate 14 at body of wall 1 and the wall back of the body 12 are provided with crushed rock filler layer 6.This crushed rock filler layer 6 can be land pebble or gravelly soil, wherein gravelly soil better effects if, can increase the frictional force of body of wall and massif, makes body of wall more stable.Massif or the immersion of underground are discharged to outside body of wall by the hole in crushed rock filler layer 6, serve fine protective effect to body of wall.
Consider the gear aesthetic property of protection structure and the protection to ecological environment, in the metope position of body of wall 1 and the turn-up section 21 of geo-grid 2, be provided with the grid anti-package body 5 be paved into by the ecology bag filling soil.The ecology bag filling soil is adopted well to prevent erosion.After ecology bag has been laid; vegetative coverage can be carried out above; along with plant roots and stems constantly grows, ecology bag and ecology bag, ecology bag and rear side slope can be joined together to form an Ecological Slope closely, not only improve the stability of body of wall 1 but also be conducive to the protection of surrounding environment.In ecology bag, also can load sand, because the water permeability of sand is better, can prevent ponding from having an impact to body of wall, also be conducive to the growth of vegetation simultaneously.
