Abstract
The invention discloses a kind of concrete film bag retaining wall, including agent structure and waterproof/drainage structure two large divisions.Described agent structure is made up of concrete film bag baffle plate (1), platform and slope concrete film bag (7) with original state Soft Rock Body (18)；Described waterproof/drainage structure oozes french drain, is made up of the platform gutter (15) and the domatic part of three-dimensional grass planting three of clay (9) composition on bracket supports plate (2), palisade supporting plate (5) and platform including cutting for being made up of permeable geotextiles (10), flexible porous tube (11) and crushed rock filler (12).A kind of concrete film bag retaining wall is a kind of side slope toe wall based on the shearing strength of original state Soft Rock Body (18), compared with existing mortar flag stone retaining wall, with the significant advantage such as low cost, the simple and environmentally-friendly property of constructing be good, it is particularly suited for the cut slope that toe is the Soft Rock Bodies such as easy-weathering mud stone, carbonaceous shale.
Description
Technical field
The present invention relates to a kind of retaining wall of cut slope, a kind of concrete film bag retaining wall is especially related to.
Background technology
There is the shearing resistance more much higher than general great soil group under the Soft Rock Body natural moisture such as unweathered mud stone, carbonaceous shale
Intensity, after slope excavating, under rainfall, is also easy to produce humidifying disintegration and softens destruction, and the mud stone, carbonaceous shale after humidifying are soft
Shear strength of rock can drop to less than 1/10th of strength of raw rock, therefore, for the mud stone, the charcoal that have thicker Weathering-residual soil
The highway cutting side slope of the Soft Rock Bodies such as matter shale typically must toe set mortar flag stone retaining wall with prevent Rainfall simulator erosion and
Humidifying causes the damaged or destroyed by flood avalanche that the humidifying of toe soft rock is disintegrated and its induces side slope to destroy.Mortar flag stone retaining wall easy construction,
It is China's slope supporting structure most widely used at present, but mortar flag stone retaining wall speed of application is slow, it is artificial relatively steep many because needing,
Security is poor, and in addition with the raising of China's civilian worker's labor cost, cost is also greatly improved.
The content of the invention
The technical problems to be solved by the invention are by soft to be distributed in mud stone, the carbonaceous shale etc. of cut slope toe
Rock rock mass provides a kind of parcel enclosed environment
The natural rock mass retaining wall on basis.
The present invention forms the enclosed environment (Fig. 1) of Soft Rock Body by using wrapping up for concrete film bag, i.e., by
Domatic lower setting concrete film bag baffle plate (1), platform and slope concrete film bag (7) can be by original state Soft Rock Body (18) closings
Keep apart, prevent rainfall humidifying from causing the shearing strength of Soft Rock Body (18) that excessive decay occurs；So, by concrete film bag
The Soft Rock Body (18) of baffle plate (1), platform and slope concrete film bag (7) parcel just constitutes one and is made up of natural rock mass
Retaining wall.
The present invention also realizes acting on domatic and toe guarded drainage by setting waterproof/drainage structure.Described guarded drainage
Structure oozes french drain including cutting for being made up of permeable geotextiles (10), flexible porous tube (11) and crushed rock filler (12), by bracket branch
The platform gutter (15) and domatic three-dimensional grass planting that clay (9) on fagging (2), palisade supporting plate (5) and platform is constituted are anti-
Three parts of sheath constitute.
In sum, a kind of concrete film bag retaining wall that the present invention is provided is a kind of with the anti-of original state Soft Rock Body (18)
The retaining wall based on intensity is cut, it is good etc. notable with low cost, the simple and environmentally-friendly property of constructing compared with mortar flag stone retaining wall
Advantage, is particularly suited for the reinforcing to the cut slope that toe is the Soft Rock Bodies such as easy-weathering mud stone, carbonaceous shale.
Brief description of the drawings
Fig. 1 is a kind of drawing of concrete film bag retaining wall.
Specific embodiment
The invention will be further described with reference to the accompanying drawings and detailed description.
Referring to Fig. 1, (in Fig. 1, (14) are the bottom width of concrete film bag retaining wall, and (19) are the platform that falls, and (20) are row
Waterside ditch), constructed as follows：
1st, after repairing slope by design completion cut slope, built in 2 meters of eminences of toe and one is excavated at step keeps to the side slope
French drain (13) is oozed in deep the cutting of 50cm 2m wide；
2nd, laying film bag and the placing concrete formation 20cm thickness concrete films in film bag in oozing french drain (13) at described section
Bag baffle plate (1), meanwhile, film bag is laid in platform and slope and placing concrete forms the thick concrete films of 10cm in film bag
Bag (7)；
3rd, one layer of permeable geotechnique is laid in the position that more than the bottom 30cm of the side that french drain (13) is pushed up by slope is oozed at described section
Cloth (10), is fixed with nail, and flexible porous tube (11) then is placed in into the bottom cut and ooze french drain (13), then at described section
Ooze and the thick metallings (12) of 30cm are filled in french drain (13)；
4th, by 45 degree of inclination angles (3) and cut slope inclination angle (4) laying film bag and in film bag, placing concrete is formed respectively
10cm thick bracket supports plate (2), height (17) control is in 1 meter；
5th, the thick clay layers (9) of the 30cm of reverse ratio of slope 10% (8) are filled by Fig. 1；
6th, by 25 degree of cast-in-place palisade supporting plates (5) of inclination angle (6), platform gutter (15) is formed；
7th, three-dimensional grass planting (16) is set domatic, height control is below 5 meters.
Claims (1)
1. a kind of concrete film bag retaining wall, including agent structure and waterproof/drainage structure two large divisions, described agent structure are led to
Concrete film bag baffle plate (1), platform is crossed to isolate original state Soft Rock Body (18) closing with slope concrete film bag (7) to prevent drop
Rain humidifying causes the excessive decay of the shearing strength of Soft Rock Body (18), therefore soft using the original state with larger shearing strength
The shearing strength of rock rock mass (18) as concrete film bag retaining wall shearing strength, and by by permeable geotextiles (10), soft
Formula water-permeable pipe (11) and crushed rock filler (12) composition cut ooze french drain, by bracket supports plate (2), palisade supporting plate (5) and platform
On clay (9) constitute platform gutter (15) and the domatic part of three-dimensional grass planting three composition the waterproof/drainage structure, realize
To domatic and toe reinforcing and protection.
