Description

A kind of bank revetment foundation consolidation process technology in soft formation side slope
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.
