Accompanying drawing explanation
Fig. 1 is process chart of the present invention.
Detailed description of the invention
Below in conjunction with drawings and Examples, technical scheme of the present invention is described further.
Lower well and catch-basin construction technology, comprise following methods step:
1). construction lofting;
2). excavation pit;
3). build well body by laying bricks or stones;
4). the borehole wall is wiped one's face;
5). backfill;
6). crib is installed
7). walling crib and well lid are installed;
8). concrete making
9). backfill around the borehole wall
10). the compacting of well week
Below described in detail.
For step 1), in newly-built road, if construction lofting is not careful, lower well, catch basin cover collimation mark can be caused high higher or on the low side, be connected uneven with road surface.At present, in the construction line-putting, be after having puzzled curb mostly, the absolute altitude with reference to the absolute altitude lateral stay determination well small cup of curb is this, and method is simple, but there is any discrepancy easily to make actual elevation and design elevation.
For step 2), the lower well foundation ditch planar dimension of excavation can be bigger than normal and need rule, to avoid the refill spaces around lower well too little, causes compacting facility to operate.In addition, strictly should construct by the construction organization requirement of construction technology code and establishment, artificially can not reduce the excavated section of foundation ditch, in order to avoid compacting facility cannot operate, cause the unreal or void of backfill to be filled out and cause sedimentation around well catch-basin under road.
For step 3), 4), when lower well wall is built by laying bricks or stones, should ensure that the quality of masonry mortar reaches design grade, mix and stir and want evenly, workability will be got well.When building by laying bricks or stones, mortar is full, and jointing wants tight, and Brick for building, material will meet requirement of strength.What also will ensure crib and its structure in construction builds reality, prevents from rolling or deforming under other External Force Acting.Should avoiding when coordinating the road construction lifting borehole wall, building coarse and mortar by laying bricks or stones and not reaching intensity and just stand load extruding, in order to avoid borehole wall surrounding brick wall becomes to loosen state, causing lower well to go wrong.
In addition, needed again to build by laying bricks or stones with high strength strength mortar morning by the brick walling perturbed to well head place.Should clean before wiping one's face and moistening brick surface.When wiping one's face, timely press polish receives slurry and maintenance.When meeting underground water, wipe one's face and jointing should complete in time with building by laying bricks or stones, can not backfill after carry out again in wipe one's face or interior jointing.Strengthen manhole well body is connected part masonry strength with road surface.Block strength is not less than m10 or changes cast-in-situ concrete within the scope of the borehole wall topmost 500mm.Mortar strength is not less than m10, and concrete strength is not less than c25.
For step 5), around lower well, catch-basin during backfill, suitably process done by reply filler, backfills, instead of backfill according to the undisturbed soil after roadway excavation groove according to soil property in plan; Meanwhile, should packing quality be ensured, guarantee the compactness of backfilling material, can not for saving cost and gathering materials on the spot, avoid causing lower well, catch-basin periphery to sink because of packing quality problem etc.
When carrying out backfill construction, answer the optimum moisture content of attentional manipulation backfill, bigger than normal or the less than normal and backfill building waste degree of compaction that all will compacting be made not reach requirement of the water content of soil, causes manhole surrounding soil to sink.If do not reach optimum moisture content in order to work to tight deadlines in backfill just to backfill, very easily form the sudden change of spring soil or sedimentation.
For step 6), the connected mode of crib and well body need be improved.Tusk can be increased at the bottom of crib, or make it be embedded in body of wall or concrete to increase stability at the base of crib punching pre-embedded bolt, or to take boring pre-embedded bolt to run through the concrete connected mode of the borehole wall to fix in the side of crib, strict with job specfication operation, improve construction technology.When crib is installed, should by highness change within 5mm.
For step 7), 8), after crib installs and be errorless on inspection, walling crib and well lid could be installed, then can carry out the making of bituminous concrete.For the ease of paver work, ensure road evenness, should before asphalt concrete pavement pave, by walling crib Pass line adjustment to lower than design road surface elevation 10-20mm, after asphalt paving has rolled, horse back adjust walling crib, makes the smooth-going joint on itself and road surface.
Consider impact in winter, the setting height(from bottom) of lower well should be advisable lower than road surface 0 ~ 5mm.When laying walling crib, the stuffing box packing that intensity is higher must be selected, and timely mortar plugs the gap, walling crib is laid firmly.Grouting material should be selected has early strong, high-strength, easy flowing and micro-swollen non-shrinking material, and its design strength should at more than c30, and placing highly should not be less than 6cm.
For step 9), want back-filling in layers when lower well periphery backfill, every layer of backfill THICKNESS CONTROL at 250-300mm, and is tamped, until the height of foundation on road surface with vibratory plate compactor.Lower well periphery backfill can not use brickbat, tile fragment, dregs rubbish etc., in order to avoid cause depression.Backfill as when not drying rainy season, then all adopts rendzinas or sand backfill, can ensure the sudden change of its compactness and sedimentation like this.If work to tight deadlines, then filler answers that selection intensity is high, compacting fast, the material of good water permeability is as boulder and cobble, rubble, medium coarse sand etc.
For step 10), when well, catch-basin occur sinking instantly, should adjust in time, adjust again when can not by the time sink fairly obvious, so just be guaranteed that driving is comfortable and the appearance of the city is attractive in appearance.When maintenance lower well, catch-basin, first should detect the ground after excavation, as bearing capacity of foundation soil existing problems, multiple rammer can be adopted or change and fill out dirt, the good material of gravel equivalent-load power tamping.
