Description
Technical field
The invention belongs to soft foundation processing technology field more particularly to a kind of soft formation side slope bank revetment foundation consolidation process sides
Method.
Background technique
Soft formation basis refers to the ground being made of Soft Soil Layer.Weak soil generally refers to that natural moisture content is big, compressibility is high, holds
Carry that power is low and the very low cohesive soil in soft modeling~liquid-plastic state of shearing strength.Often weak soil is subdivided into soft stickiness in engineering,
Muck soil, mud, in peat matter and peat etc..With natural moisture content is high, natural void ratio is big, compressibility is high, shearing resistance is strong
Spend low, the coefficient of consolidation is small, consolidation time is long, high sensitivity, perturbation are big, bad hydraulic permeability, soil layer layered distribution are complicated, each layer it
Between physico-mechanical properties difference it is larger the features such as.Because its engineering characteristic determines that soft formation foundation bearing capacity is low, foundation deformation is big,
Inhomogeneous deformation is also big, and deformation lasts longer, frequently results on soft formation structures and the harm such as sedimentation, inclination occur, seriously may be used
Cause structures collapse or can not normal use the case where.
In recent years, on riverine, along the lake, coastal etc. widely distributed the soft formation basis in China, these areas are general to be again
Developed area, it is urgent to requirement of engineering, especially to develop heavy construction.Soft formation foundation capability is poor, sliding
The problem of destroying often soft formation ground aspect is caused.For the engineering characteristic on soft formation basis, in many years theoretical research
With a variety of soft formation reinforcing and processing methods are formd on the basis of practice, such as change fill out cushion layer technique, precompressed foundation technical, compacting and
Compacting foundation technology, composite foundation technology, grouting reinforcement technique etc., reinforcement mechanism, construction technology, the scope of application and advantage and disadvantage are mutual
There are the similarities and differences, be summarized as follows:
Method 1: chemical consolidation technology.The methods of deep-layer stirring, high-pressure rotary-spray, slip casting are used, pile body is formed.It compares
In soft formation, pile body has the characteristics that high-intensitive, rigidity, and in soft formation form compound foundation shared superstructure lotus
It carries, improves soft formation foundation bearing capacity to reach, reduce deformation quantity.This method is applied widely, consolidation effect is significant.But
It applies man-hour requirement and is equipped with professional construction mechanical equipment, and occupied area is larger；And work progress vibration is larger, is not suitable for from building
Object immediate area is easy to produce disturbance and disturbs residents；Earthwork water-content indicator control is more stringent, easily causes spongy soil, needs specially
Door carries out research use.
Method 2: precompressed foundation technical.Piling prepressing or vacuum preloading are carried out i.e. on ground, or be used in combination preloading and
Vacuum preloading, the ground after forming consolidation.It is primarily referred to as sand drain load precompressed ground, it has, and consolidation rate is fast, constructs
The features such as simple process, effect are good, use scope is wider.It is squeezed into the soft clay containing saturated water or alluvial soil ground
A batch draining sand drain, stake top are laid with sand bedding course, and the first loading precompressed by stages on sand bedding course makes soil layer pore water constantly pass through sand
Well rises, until earth's surface is discharged in sand bedding course, before architecture construction, the most of earlier discharging consolidation of foundation soil reduces building
Settling amount, enhance foundation stability.Precompressed ground is suitable for the saturation cohesive soil such as processing muck soil, mud, rinse fill
Ground, needs to prepare that special construction equipment, construction process requirement are higher, is suitble to the consolidation process of large area smooth location, work
Phase is long, and cost is higher.
Method 3: it changes and fills out cushion layer technique.Excavate a certain range of soft layer or uneven soil layer under the bottom of foundation,
Other performances stabilization, non-corrosive property, the higher material of intensity are backfilled, and tamps the bed course of closely knit formation.To soft soil foundation into
Row changes when filling out cushion layer technique processing, should carry out detailed analysis to geology first, and formulate reasonable construction plan；Secondly, wanting
Select suitable replacing method according to the actual situation or change the earth that bankets, under normal conditions the material of backfill mainly by earth material,
Block stone and pool slag etc.；It is controlled finally, exchanging filling density again, by modes such as artificial or mechanical equipments to replacing method
A degree of roll and tamp, it is ensured that construction quality.Such processing mode is only applicable in shallow poor subsoil layer or uneven
The basement process of soil layer, replacement thickness are 0.5m~3.0m.Construction technology is simple, construction equipment is easy, and material easily obtains.
Method 4: deal pile technology.Hydraulic engineering bank revetment foundation middle-size and small-size for part, frequently with the small deal pile of 4.0m long
Carry out soft formation consolidation process.These middle-size and small-size hydraulic engineering soft formation depth are generally no greater than 3.0m, act on soft formation and answer
Power is not high, and middle-size and small-size hydraulic structure is often in line style, in this case, such as uses large-scale conventional soft formation processing technique,
Then have large scale equipment transition is difficult, construction site condition is poor, construction material transport difficult, basic excess processes, cost height,
The problems such as long in time limit.The many factors such as mixed economy, technology, quality, progress consider, deal pile processing is often carried out in engineering and is applied
Work, progress is fast, expense is few.The key of this technology is that deal pile will even flow plastic state across the poor soft formation of geological conditions
Soil layer reaches harder supporting course, and to play pile foundation effect, otherwise deal pile will be slided with weak soil, and ground is not
Surely, superstructure generates sliding failure, can not normal use.
Above-mentioned several prior arts can play the role of consolidated subsoil, but during channel protection, and soft formation is in old
River location, and be in shore protection side slope when, the reinforcing mode of the prior art can be led to the problem of, and side slope that treated is in superstructure
It can be slided with weak soil under load action, so that ground is unstable, superstructure be caused to be unable to satisfy normal use requirement.
Such as Chinese Patent Application No. are as follows: a kind of high gradient slope of the patent disclosure of CN201710996795.X reinforces greening dress
It sets and reinforces greening method with high gradient slope.The present invention includes reinforcement three-dimensional polypropylene gauze pad, U-shaped nail, anchor pole, vegetation seed, soil
Earth improves fibre blend, anti-erosion fibre blend, fiber filter pipe and chock.Construction technology of the present invention is simple, operation side
Just, after the reinforcement three-dimensional polypropylene gauze pad being fixedly installed on the slope surface of high gradient slope by the anchor pole and the U-shaped nail,
It is being laid with fiber filter pipe, in the mixture and vegetation seed of sequentially sow grass seeds by duster vegetation seed and soil improvement fibre blend and anti-
The mixture of erodable fibers mixture.The invention can effectively improve the Soil Habitat of plant growth, provide growth generation for plant
It thanks to required nutrient, solves existing high gradient slope reinforcement means and be easy to be washed away by heavy rain, cause secondary landslide, collapse and protect
Aqueous difference, while the technological deficiency of secondary pollution can be caused to environment.But the invention is not directly applicable channel protection mistake
Journey.
