Description
Technical field
The present invention relates to a kind of mold-bagged concrete protective slope structure and a kind of steel reinforcement cage with anchor structure, belong to ground work
Journey field, it can apply in fields such as Hydraulic and Hydro-Power Engineering, municipal works, river regulations.
Background technology
Mold-bagged concrete bank protection has rapid, saving expense of constructing, particularly applied under water compared with traditional masonry project
The convenient superiority of work.External mold-bagged concrete bank protection sees the Toronto navigation channel experiment work being completed for 1969 earliest
Cheng Zhong.After the eighties in 19th century, according to the invention of American Architecture technology company, (nineteen sixty is special for Japanese Asahi Kasei Corporation
Profit) various mould bags have been made with the type cloth of high tenacity polyester fiber 66 it is also known as method cloth.Method cloth has water penetration, make concrete residual moisture by
It can in time be excluded after to pouring pressure, reduce the ratio of mud, accelerated concrete or mortar solidification, obtain high density, high intensity
Concrete or mortar masonry.China just promotes the use of geotextile in hydraulic engineering in recent years, and mold-bagged concrete is coastal
Applied in dike mill, river slope bank-protection works and also belong to the stage at the early-stage.
Mold-bagged concrete bank protection is exactly with woven geotechnical fabric bag to make Flexible formwork assembly, using concrete pump by microlith coagulation
Soil pressure enters mould bag, and formation has certain thickness, the concrete unit of certain planar dimension, and some units are coupled to by mould bagging
It is overall, so as to reach the function of bank protection.
Mould bag belongs to geosynthetics, and it is with double-deck baggy fabric of the high-strength chemical-fibre long filament through being woven from.Mould bag
Along 2 directions in length and breadth every a segment distance (being mostly 25cm~20cm) between upper and lower two layers, have certain length (be mostly 7cm~
Nylon rope 10cm), upper and lower two-layer fabrics are bound up, and the thickness for controlling perfusion to shape.Because it can play template
Effect, therefore be called mould bag.Mould bag basic pattern can be divided into mortar type and coagulation type according to packing material difference, according to mould bag
Bank protection effect is different with structure.Because uniform section type concrete lining self-bearing ability is strong, 1 can be layered on：On 1 abrupt slope, it can increase
Add domatic stability against sliding, prevent from coming down.It is commonly used for River Embankment bank protection, channel, pond lining cutting.
Currently in order to preventing mould bag coasting, often it is appropriately arranged with beyond top of the slope mould bag upper limb binds concrete groove
The stake of gully position.The spacing of guide pile is depending on the conditions such as length of grade, the gradient, mould bag thickness.Typically demarcate in the junior unit of mould bagging
Face sets a guide pile, is fastened the steel pipe penetrated in mould bag perforation hole with nylon rope, and the other end is by take-up device with determining
Position stake is connected.With strand thick stick is tensed on per pile, to adjust mould bag upper and lower position and stent bag.The larger construction of stormy waves shows
, it can be disperseed to push down the mould bag completed with sand pocket, prevent stormy waves from conjugate mould bag.But slided preventing mold-bagged concrete protective slope structure
Dynamic fixing device is relatively single, often lacks complete protective slope structure system, causes many mold-bagged concrete bank protections to be transported
Sliding rupture just occurs after row a period of time.
The mold-bagged concrete protective slope structure found at present, it is the most famous with following two：First, Ling Chunhai et al. is introduced
The third villages of Mei Jiang power station flood season left bank diversion canal uses the applicable cases and effect of geotechnical fabric bag concrete revetment, referring to [icepro
Spring is extra large, Zhang Zhenxin, application [J] the people pearls of Zhang Yuanhai geotechnical fabric bags concrete in the protection of the third village power station left bank flood season
River, 2003,6:33-35 pages of], due to open channel excavation slope by design 1：1 is changed to l：0.4, whole side slope is top-heavy,
Under the influence of current, side slope pin, which is necessarily formed, draws brush.For this, opposite side toe is covered with block stone presser feet, side slope with rock ballast, spats and
The upstream face of bank protection carries out erosion control processing using mold-bagged concrete.Presser foot block stone design side slope is 1: 1.2, bottom width 10.5m, is filled out
High 4m；Bank protection rock ballast is filled on presser foot block stone, and design side slope is 1: 1.2, bottom width 6.3m, top width 1.5m, is filled to elevation
68m, bank protection bottom set the maintenance packway of a wide 1m.

[application [J] the engineering constructions of Liu Yangmin, Yue Yi power geotechnical fabric bags concrete in Hydraulic and Hydro-Power Engineering bank protection, 2004,117
(3)：54-55 pages of], project post-evaluation design is wide without filter point mould bag using C20 mold-bagged concretes lining shield, mould bag model rectangle
4m, it is 150mm to enrich thickness, and seam crossing is using geotechnological anti-filter cloth overlap joint wide 1.6m.The laying of geotechnical fabric bag is applied using segmentation
The method of work and continuous productive process is carried out.Vertical dike can axially be divided into 3 sections of base section, concrete revetment section and horizontal bedding section, suitable
Dike is axially 1 section (using mould bag breadth 4m as modulus) per 12m.Every section carries out base section construction first, then carries out slope successively
Section and the construction of bedding section or both are constructed simultaneously.Direct-axis to can it is separated by a distance progress multistage parallel operations, two construction sections away from
From using 12m as modulus.Slope section geotechnical fabric bag is laid from top to bottom, is worn in top of the slope with what steel pipe penetrated that top of the slope mould bag sews in advance
In pipe cloth, fixation is adjusted.Horizontal bedding is laid from toe to bedding head end.Mould bag tension and relaxation appropriateness is paid attention to during laying, is avoided
Stress concentration and artificial damage.Want modulus bag to be coincide with ground, layer contacts face smooth, prevent mould bag wrinkle from forming penetrating passage
Phenomenon.Underwater portion is then first pulled open mould bagging with canoe, is then lain in mould bagging on station keeping ship with rope, to prevent water
The mould bagging volume of lower part together or positioning, again loosens rope in concrete filling., will while mould bag is laid
The reserved draining hole site of PVC drain pipe insertion mould bag, then carry out charging for concrete.
Current technology is often only referred to how to lay mold-bagged concrete, and for fixed, bottom at the top of mold-bagged concrete
Presser feet is introduced seldom, and currently used way is exactly to take to make along the processing of slope ditcher fill concrete, bottom boundary at top
Handled with boulder presser feet.This processing method often leads to that top destruction just occurs after using very short time, and it is sliding to produce part
Move, the phenomenon of top solid failure occur.And sliding phenomenon often occurs under strong flow action in bottom boulder, so as to from mould
