Description
Technical field
It is comprehensive more particularly, to a kind of Novel underground the invention belongs to the technology in underground pipe gallery foundation pit cut and cover tunneling
Close piping lane method for reinforcing side slope.
Background technology
It is cost-effective, major part is applied using cut and cover method currently, in the underground pipe gallery work progress of large size city
Work.In cut and cover tunneling, the slope reinforcement after excavation of foundation pit is the key that foundation pit job safety.Normal practice is, using digging
Machine brush slope is excavated to after the sloping coefficient of design requirement, is just sprayed a layer concrete first, is then hung reinforced mesh again, installation is let out
Water hole is finally reinforced using short nail, and anchor concrete support is sprayed.If such method supporting because drain hole blocks, leads to water excretion not
Go out, accumulated time, the pore water pressure in soil can be increased, and then conduct oneself with dignity plus the soil body, when its gravity is more than the anti-of spray anchor face
When cutting ability, the danger on slope failure landslide will occur.Piping lane foundation pit needs backfill to handle after the molding of piping lane main body, at this time
Anchor face will be sprayed by, which needing, removes, and forming a large amount of concrete residue and reinforced mesh can not reuse, and result in waste of resources and increase
Add support cost.
Invention content
To solve the above problems, the present invention proposes a kind of Novel underground pipe gallery method for reinforcing side slope, using waste and old wheel
The mode that tire, short nail, waterproof geotextiles are combined carries out consolidation process to piping lane excavation slope, easy for construction and at low cost.
The specific technical solution of the method for the present invention is：
Step 1：Slope Treatment
It answers first side slope effectively to be cleared up before construction, by easy landing, influences the unconsolidated formation of stability of slope, miscellaneous soil
Deng removing, keep slope surface smooth as far as possible, in favor of the laying construction of waste tire.
Step 2：Waterproof geotextile laying
After the completion of side slope is cleared up, the laying of waterproof geotextiles is carried out.Paving is manually rolled when laying, cloth cover wants smooth,
And suitably there are distortion allowances.Geotextiles, according to the difference of landform, can be divided into nature overlap joint, sew up or weld in overlap joint.
Step 3：Waste tire is laid with
Waste tire is laid with one by one from slope foot to top of the slope, when laying, pre-designed tire tread layout and short nail position,
So as to short nail preferably combined with tread layer it is integral；It is continuously soft that composition tire is directly coupled using steel wire between tire and tire
Soft face layer, allows tire being entirely spatially unified into an entirety, increases the ability of its globality and antiskid slope.
Step 4：Short nail implantation
After the completion of waste tire is integrally laid with, short nail is implanted into, short nail one end is deeply inserted into the soil body, other end bent anchor
Fixed tire.
Compared with prior art, it is the advantages of the method for the present invention：
1) in terms of materials of constructing, when foundation pit backfills, the spray anchor face layer after removing can produce the combined bolting and shotcrete of conventional method
Raw a large amount of building waste causes the waste of resource, and waste tire, short nail, waterproof geotextiles can repeat in the present invention
It recycles, when piping lane foundation pit backfills, can retain and be continuing with after removing；
2) waterproof geotextiles have good water permeability in the present invention, and have preferable antiskid slope ability, water penetration
It so that rainwater is flowed into foundation pit along waste tire, water will not be made to be deposited in the soil body, cause the pore water in the soil body
Pressure rise, and then generate the danger on landslide；
3) the waste tire tyre surface in the present invention has larger friction coefficient, and the dead weight of tire itself, which can also increase, to rub
Power is wiped, and then ensures that slope soil is not in landslide；
4) waste tire is coupled by the way of link in the present invention, and entire slope surface connects into an entirety, subtracts
The danger on small landslide.
Description of the drawings
Fig. 1 is waste tire supporting schematic diagram in the present invention；
In figure：1, waste tire, 2, short nail, 3, waterproof geotextiles, 4, steel wire, 5, side slope.
Specific implementation mode
In conjunction with attached drawing to a kind of novel underground pipe gallery method for reinforcing side slope method proposed by the invention make into
The explanation of one step.
The foundation pit stope support that the method for the present invention can be used for cut and cover method is reinforced, and concrete operation step is as follows：
Step 1：The processing of side slope 5
It answers first side slope 5 effectively to be cleared up before construction, by easy landing, influences the unconsolidated formation, miscellaneous of the stabilization of side slope 5
The removings such as soil keep slope surface smooth as far as possible, in favor of the laying construction of waste tire 1.
Step 2：Waterproof geotextiles 3 are laid with
After the completion of side slope 5 is cleared up, the laying of waterproof geotextiles 3 is carried out.Paving is manually rolled when laying, cloth cover will be put down
It is whole, and suitably there are distortion allowances.
Waterproof geotextiles 3 in this step, according to the difference of landform, can be divided into nature overlap joint, sew up in overlap joint
Or welding.
Step 3：Waste tire 1 is laid with
Waste tire 1 from bottom to top, i.e., is laid with one by one from slope foot to top of the slope, when laying, pre-designed tire tread cloth
Office and 2 positions of short nail, so as to it is short follow closely 2 preferably combined with tread layer it is integral.Steel wire 4 is directly used between tire and tire
The continuous flexibility face layer of composition tire is connect, allows tire being entirely spatially unified into an entirety, increases its globality and antiskid slope
Ability.
Step 4：2 implantation of short nail
After the completion of the whole laying of waste tire 1, short nail is implanted into, short nail one end is deeply inserted into the soil body, and the other end is curved
Waste tire 1 is determined in anchoring.
The present invention apply underground pipe gallery foundation pit stope support reinforce, can meet construction need under the premise of,
Pattern foundation pit supporting structure cost is greatly lowered.First, in terms of materials of constructing, the combined bolting and shotcrete of conventional method is taken off when foundation pit backfills
Spray anchor face layer after removing will produce a large amount of building waste, cause the waste of resource, and waste tire, short nail, waterproof geotextiles
It can repeat to recycle, when piping lane foundation pit backfills, can retain and be continuing with after removing.Secondly, waterproof geotextiles tool
There is good water permeability, and there is preferable antiskid slope ability.Water permeability preferably can make rainwater along waste tire stream
Enter foundation pit, water will not be made to be deposited in the soil body, the pore water pressure in the soil body is caused to increase, and then generates the danger on landslide.So
Afterwards, waste tire tyre surface has larger friction coefficient, and the dead weight of tire itself can also increase frictional force, and then ensure side slope
The soil body is not in landslide.Finally, waste tire be using link by the way of coupled, entire slope surface connect into one it is whole
Body reduces the danger on landslide.
