Description
Technical field
The invention discloses a kind of spigot-and-socket reinforced concrete sewer pipe installation method based on graded broken stone basis.
Background technology
Spigot-and-socket reinforced concrete sewer pipe is widely used in city as one kind and had stable political situation other drainage systems recently（Such as scape
See draining）In pipeline its have following advantage：1. using " O " shape section, slidingtype rubber ring sealing, have excellent close
Sealing property；2. using flexible interface, installing angle is big, can effectively prevent the pipe joint caused by settlement of foundation, earthquake etc.
Seepy question；3. it is easy for construction, it is reliable quick.
Atlas is installed according to drainpipe at present《Municipal administration drainage channel project and affiliated facility》（06MS201）Construction work
Skill, spigot-and-socket reinforced concrete sewer pipe have two kinds of installation methods, are sandstone basis mounting process and concrete foundation peace respectively
Dress technique.
Atlas《Municipal administration drainage channel project and affiliated facility》（06MS201）The sandstone basis used and concrete foundation are deposited
In following shortcoming：1. need, to the accurate leveling of tube seat, to waste a large amount of manpowers before Pipe installing；2. sandstone basis needs pipeline
Installed in pipe pillow on, and pipe pillow and backing plate be required in advance it is prefabricated, when pipe pillow reach due intensity when could use, this is just needed
Construction period that will be longer；3. concrete foundation is not because operational sequence accounts for any advantage relative to sandstone basis too much yet, more
What is added is time-consuming, laborious, can not also play advantage possessed by spigot-and-socket reinforced concrete sewer pipe completely.
The content of the invention
Long in time limit, costly in the old mounting process of socket joint concrete drain tile to solve the problems, such as, the invention provides hair
The leakproof advantage of spigot-and-socket reinforced concrete sewer pipe in itself is waved, construction costs is reduced, shortens the broken based on grading of construction period
The spigot-and-socket reinforced concrete sewer pipe installation method of stone foundation.
To achieve these goals, the technical solution adopted in the present invention is：A kind of socket joint based on graded broken stone basis
Formula reinforced concrete sewer pipe installation method, it is characterised in that comprise the following steps：（1）Preparation of construction；（2）Surveying setting-out；
（3）Pipeline groove excavates；（4）Lay graded broken stone basis；（5）Pipe installing；（6）Inspection shaft is built by laying bricks or stones；（7）Closed-water test；Its
In：
The step（3）Described in " pipeline groove excavation " refer to according to step（2）In accurate measurement channel excavation side
Line, channel excavation is carried out along excavating sideline.The order of excavation is that excavation is upstream fallen back from downstream.Examined at any time in digging process
Position, size and the bottom land absolute altitude of groove are checked, is not backbreak, and bottom land is flattened roughly；
The step（3）Described in " laying graded broken stone basis " refer to, by deployed graded broken stone mixture, utilize digging
Machine or forklift are backfilling into tube seat, and carry out compacting finishing to the graded broken stone mixture of backfill, it is ensured that its compactness and top surface
Size meets Pipe installing requirement；
The step（5）Described in " Pipe installing " its detailed process be：
A) before the installation of spigot-and-socket reinforced concrete sewer pipe, once review is carried out to basic elevation, pipe centerline and checked, warp
Cross check it is errorless after can carry out pipeline mounting construction.
B) spigot-and-socket reinforced concrete sewer pipe installation comb order be from downstream row upstream.Spigot-and-socket reinforcing bar mixes
The direction of solidifying native drainpipe socket insertion is consistent with current.When limiting needs arrangement placement half-section pipe because of well section distance, half-section pipe
Inspection shaft Inlet and outlet water both sides are come, the half-section pipe of carrying spigots comes the water outlet direction of inspection shaft.
C) pipeline is first clean by the oil removal on the outside of the socket of tube coupling and on the inside of bellmouth before additionally arranging.Advised according to caliber
Lattice select corresponding rubber seal, and in inserted jack groove, it is desirable to accomplish that surrounding is uniform, smoothes out, be distortionless.
D) during down tube, suspension centre is arranged on the center of gravity of pipe.In handling, tube coupling interface is prevented to be damaged.
When e) pacifying pipe, tube coupling is steadily hung down, moves to the interface of comb, adjusts the absolute altitude and axis of tube coupling, then
Symmetrically slowly tensed in both sides with tight pipe chain block and the socket of pipe is inserted into bellmouth, during socket joint pipe, tube coupling
There is still a need for suspend in midair, resistance during reducing tight pipe.After tube coupling socket and bellmouth coincide, the axis and mark of pipe are adjusted
It is high.When tube coupling socket inserts, it should be noted that rubber ring occurs without phenomena such as distortion, de- groove.
F) when pipe socket joint loosens chain block in place, check that the gap n between bell and spigot is 10mm ~ 15mm.
G) macadam-aggregate mix is inserted into pipeline both sides, to obtain fixed -piping, the effect that prevents it to be subjected to displacement.
Preferably, tube seat bottom width is spigot-and-socket reinforced concrete drainage pipe external diameter+every side working width * 2；Often
Side working width：It is 40cm as bore≤500mm；As bore≤1000mm and it is 50cm when being more than 500mm；When in pipe
Footpath≤1500mm and be 60cm when being more than 1000mm；Work as bore>It is 80cm during 1500mm；
Preferably, described graded broken stone mixture is made up of the raw material of following parts by weight：Rubble 60%, aggregate chips 40%.
Preferably, the thickness of graded broken stone mixture layer is not less than 20cm；The width of graded broken stone mixture layer is not small
In drainage pipeline outside dimension+2* per side 10cm；Graded broken stone mixture layer is graded broken stone basis.
Preferably, the mixing and stirring, transport of graded broken stone mixture, backfilling process are as follows：
A) graded broken stone mixture is tested before constructing, compound maximum particle diameter is not more than 25cm；
B) in compound central mix place, the rubble of 60 parts by weight and the aggregate chips of 40 parts by weight are fully mixed and stirred stand-by；
C) graded broken stone mixture is transported；
D) graded broken stone mixture backfills：
The thickness of backfill is not less than adds every side 10cm*2 in 20cm, the width of backfill not less than drainage pipeline external diameter.
Relative to prior art, beneficial effects of the present invention are：Give full play to spigot-and-socket reinforced concrete sewer pipe in itself
Leakproof advantage, reduce construction costs, shorten the construction period；With convenient material drawing, technique is simple, shorten the duration, saves cost
Etc. advantage；This kind of method is low with the requirement on basis to groove, as long as making simple leveling to bottom land, can to carry out grading broken
Stone foundation place mat, then peace pipe, can be carried out inspection shaft immediately and built by laying bricks or stones, closed-water test, backfill to pacify pipe in grooving.This method
Technique is simple, easy for installation, quick construction, short time limit, and expense is low.
