Background technology
In recent years, along with socio-economic development, urban construction scale was constantly expanded, supporting being gradually improved such as relevant municipal pipeline, due to factors such as urban land restrictions, most municipal pipelines often need be laid on roadway, cause all kinds of manhole magnitude settings on the roadway of city to increase year by year.Often there is well lid distortion or the sound of making an uproar in the manhole after date in the time using a section being distributed on roadway, a series of common faults such as all pavement cracking of well and depression, destroy road structure, cause surface evenness bad.And automobile is when at a high speed through manhole, the dynamic impact effect that can produce to manhole transient state, aggravates its breakage, and the depression of manhole simultaneously etc. can have a negative impact to vehicle traveling comfort and safety on it again conversely, even causes traffic accident.And along with the development of manhole periphery road surface breakage, rain, snow-broth etc. infiltrate supercrust along crack, have further accelerated well week road surface structural damage, form vicious circle, the application life of having reduced widely road.Therefore, manhole disease problem can not be ignored, and need take in time reliable measure to keep in repair regulation, not only can improve transportation condition and the landscape effect of urban road, and extended Road Service Life, and save road life-cycle operation cost, embody low-carbon environment-friendly theory.
Concrete analysis manhole produces the reason of disease, mainly contains:
1. the structural deterioration that building materials low strength causes.China's manhole adopts cement mortar brick construction more at present, because mortar in construction is sprawled inequality, out-of-flatness or not full, in addition fragment of brick surface irregularity, this just makes every brick is no longer all uniform-compression, but in pressing, curved, the compound stress cut, the reciprocation of fragment of brick and mortar lateral deformation difference in addition, cause brickwork in the time of the compressive strength much smaller than fragment of brick, to occur that vertical fracture, the development in these cracks finally make the globality of masonry be damaged and become discrete bodies.The durability of loam brick is poor simultaneously, uses after 7～8 years and will, because water, soil corrosion cause crisp rotten, obscission, can cause pit shaft unbalance stress, causes the depression and the inclination that check pit shaft under vehicular impact load action.In addition, part checks that pit shaft is provided with the section that closes up at top, this section is because brickwork is in tilted layout, masonry structure has born very large flexural tensile stress under Vehicle Load, and the tensile strength of masonry structure itself is less, the section that closes up is to check the stressed weak link of pit shaft, easily produces and destroys from here.2. manhole well lid bearing is installed unstable cause displacement and structural deterioration.Due to the needs of elevation adjustment and bearing installation, current domestic construction adopts the way that mortar bed (or claiming leveling layer) bonding manhole well lid bearing is set between bearing and pit shaft more.Because manhole belongs to the attached small-sized structure of municipal engineering, mortar generally adopts on-the-spot artificial mixing, and intensity and quality are difficult for ensureing, and mortar levelling layer thickness inequality, easily crushed under Vehicle Load, cause bearing and well lid to sink, further cause pavement destruction.3. concrete, mortar etc. reach design strength required time all more than 28 days, and exist of Municipal Engineering Construction tried to meet the deadline for the project or duration arrangement un-reasonable phenomenon more, before its intensity does not also form, just roll, very easily cause structure just deform or destroy in construction period.4. well week backfill compaction degree is defective.According to related specifications requirement, the manhole around degree of compaction of backfill should be more than or equal to the heavy compacting criteria of 95%(), and current most situation is after manhole has been built by laying bricks or stones, the gap between well and working pit is less, even because road width is limit, distance between well and well, well and curb is too small, cause cal rolling difficulty, and hand compaction is difficult to control quality, thereby causes the in use sedimentation gradually of well week backfill, cause well week road surface subsidence, manhole all around ftractures.
