Wherein, during excavation pit, foundation ditch form of fracture is digged pit mode using slope, and foundation ditch both sides are high according to side slope:Width =1:1.5 ratio slope, diameter 1.5m and diameter 1.0m foundation ditch form of fracture are distinguished as depicted in figs. 1 and 2, wherein Fig. 1 For diameter 1.5m foundation ditch sectional drawing, Fig. 2 is diameter 1m foundation ditch sectional drawing.
(1) foundation needs to meet claimed below:
1) pipeline foundation should reach design requirement.
2) when the bearing capacity of bottom land soil matrix is higher, can directly it use.But it is required that bottom land continuous formation, undisturbed soil can not be by Disturbance, must not there is the roundstone more than 400mm or the angular stone more than 25mm.
3) when the bearing capacity of bottom land soil matrix is relatively low, original soil can carry out lower road after need to being consolidated through precipitation as pipeline soil matrix Process is constructed.
4) when bottom land soil matrix bearing capacity is poor is unable to grooving, it can be handled using gravel sand.It is required that gravel layer of sand is thick Degree cannot be less than 250mm, and should tamp and clap, and should prevent gravel sand from extruding to influence basement process to imitate in bottom of trench both sides in construction Really.
5) to reduce sedimentation value, soil matrix can build up undisturbed soil and gravel layer of sand and outer diameter tube identical deep-slotted chip breaker.Arc Shape fluted shaft line should meet laying deviation requirement, and the corresponding central angle of arc is no more than 90 °.
6) medium coarse sand basis of the laying depth for DN/4 and not less than 50mm but no more than 150mm is answered on soil matrix.Basis It should tamp and surfacing, basic compactness must not be less than 90%.
(2) pipe trench is excavated, it is necessary to follow following principle:
1) when the bottom land absolute altitude excavated is below level of ground water, it should try to reduce water level.
2) no matter hand excavation or mechanical equivalent of light excavation, all should strictly by groove section dimension requirement carry out, groove should be smooth, Forbid to backbreak.
3) bottom land absolute altitude is checked at any time when excavating to close to bottom land depth, and concludes bottom land stake, it is to avoid is backbreak, if finding Backbreak, should be tamped with rubble or other aggregates.
4) when next step process can not be carried out immediately, the soil layer that bottom land should stay 15-30mm deep is not dug;Treat that next procedure is opened Dug again when work is ready, to prevent artificial or natural cause destruction bottom land basis.
(3) pipe laying is followed the steps below:
1) inspection before down tube
I. check that furrow bank has the danger of flawless and landslide.
II. whether bottom of trench width meets down tube requirement, and bottom of trench soil has undisturbed, whether there is and cave in soil productive set in groove.
III. bottom of trench absolute altitude will be met the requirements, and the place of backbreaking should be backfilling and compacted, and owe then dig to absolute altitude at digging.
IV. put ttom of pipe center line well, dig good necessary working pit.

6) bellmouth and join domain, and the neutral lubricating oil of one layer of painting inside bellmouth are cleared up with cloth again.
7) spigot seal groove is cleared up again, takes a rubber seal to check its internal diameter and joint, and apply one layer of neutral profit Lubricating oil.
8) bottom of snare primary seal groove will be sealed, and is firmly carried upwards, it is entirely fallen in seal groove, it is close in groove Seal mustn't have sth. made by twisting.
9) the axis direction centering of 2-section pipe is looked for directly, and makes socket close to bellmouth, when sealing ring touches entrance of the city, Check sealing ring and other positions, it is ensured that sealing ring position is not stained with sandy soil etc. correctly.Then pipe is slowly inserted, when slotting It when entering half, need to stop, check the position of sealing ring, to ensure that its position is correct, then continue to insertion, until regulation insertion Untill length, before upper one section pipe is not by backfill or fixation, next section pipe is forbidden to insert.
10) after each bell and spigot connection is finished, it is necessary to check the position of sealing ring at any time.Checking tool is a Steel Ruler Or other bonding jumpers, size should be length and be more than, wide, thick, smoothly be inserted in gap that can be between bellmouth and socket.By bonding jumper Or Steel Ruler insertion, circumferentially slide, check sealing ring whether have identical depth, with this judge sealing ring depth whether one Cause, whether position is correct.
11) socket joint method
For diameter especially small pipe, it can be inserted directly into manual method, during for intermediate diameter and deeper pipe trench, with digging Pick machine or jack insertion.Its method is that one block of solid wood more slightly bigger than caliber is put before bellmouth, uses excavator bucket top Firmly plank, is slowly inserted it into.For the big pipe of diameter, it can be inserted using bottle gouard moved by hands or euphroe, with semi-circular structure Snap ring blocks 2-section pipe respectively, and in pipeline both sides, symmetric position arranges two bottle gouards moved by hands or euphroe, and both sides are same during insertion Step operation, it is inclined to prevent drawing.Rubber slab is padded between snap ring and pipe.
(5) pipeline refilling step is as follows:
1) backfilling material is successively laid in pipeline both sides, and tamped on request.It should be specifically noted that the material below pipe side Compacting.The minimum-depth of initial back filled region is the 70% of outer diameter tube, and secondary backfill material in area under control can be compacted to pipe over top 150-300mm, the density of backfill is not less than 90%.
2) in caliber below 70%, every layer of backfill 200mm, during remaining is every layer of 500mm, backfilling process, both sides discrepancy in elevation limit System produces lateral displacement within one layer to prevent pipeline.
3) diameter must not is more than 40mm roundstone or the pointed shape stone more than 25mm in the region from pipeline 150mm.
4) more than area under control top 400mm backfill soil compactness is not required or operated by the requirement of owner.
The problem of should be noted in backfilling process:
1) the minimum in situ density of compacting material cannot be less than the density of design specification requirement.
2) when using impregnating method in installation process, float tube should be avoided.Piping displacement should be prevented when being banketed to pipeline bottom.
If 3) remove pipe trench plate or other protection materials, it is careful not to destroy the bed course being ready for, bottom area and initial Backfill layer.
4) during backfilling of pipe canal, answer protective conduit from the impact of whereabouts stone, the direct collision of compacting equipment and Avoid other danger for having a Latent destruction., can be in conduit upper directly using rolling when conduit upper must have 750mm overburden layers Pressure equipment rams compacting equipment again.
Wherein, fixed support placement and the process dismantled are as follows:
In backfilling process, the depth of fill reaches flushed with tube top before, it is desirable to installation personnel installs internal support, every Two meter amperes dress is together:
1) after support is installed, upper end just can banket, and specification is 20cm loess, and other can be backfilled with raw material, reach and be not less than After 50cm, upper end compacting can be carried out with road roller, it is desirable to which compactness is not less than 95%.
2) compacting is finished, and is met after compactness and depth of fill requirement, and just can let pass traffic.
3) it is more than 1m pipe for upper end height to earth up, after clearance traffic 5 days, just can all removes support.
4) diameter 1m pipe, clearance traffic can only retain the support of 3 roads, i.e. middle and both sides totally 3 road after 5 days, and remaining is complete Portion is removed.
In order that material, which is reached in the compacted density of maximum, backfilling process, takes following debulking methods:
1) it is less than 5% coarse-grained soil with fine content, such as GW, GP, SW-GP, SW-SP can by impregnating method and the method for vibrating Obtain larger compactness.
2) when using poker vibrator, every layer of backfilling material height limitation is vibrator insertion depth, if using table Face vibrator, the height of backfilling material is within 150-300mm.
If 3) with impregnating method, should prevent float tube to avoid current scour lateral support.
4) it is compacted composite soil in the coarse-grained soil containing fine grained soil more than 12%, such as GW, GC, SM, SC and group with compacting method (such as GM-SM), it is 100-150mm to lay backfill height.
5) coarse-grained soil of the compacting containing fine grained soil 5% one 12%, such as GW-GM, SW-SM, GW mono- GC, SW mono- SC, GP mono- GM, SP One mono- mono- SC of HC, SP of SM, GP, can be with compacting method, impregnating method and method of vibrating, as long as compactness meets design requirement.
Be compacted fine grained soil, such as ML, CL, SC-CL, SM-ML and ML-SL, with larger compaction force, can be only achieved by The Pu Shi density that ASTMD698 assay methods are determined, when making initial backfilling material with this kind of soil, pay special attention to defined close Degree.
