Abstract
The invention discloses a method for installing outdoor process pipelines, relates to a method for installing pipelines, in particular to a method for industrial and mining enterprises to install various process pipelines outdoors. In the method, a ditch is excavated and the pipeline is embedded outdoors. The method comprises the following steps of: a, excavating the ditch, wherein the distance from the edge of the ditch to the edge of an outdoor road is 1 to 1.5m; and the width of the ditch is 1.5 to 2m; b, tamping the bottom of the ditch, and then paving a gravel layer with gravel, wherein the thickness of the gravel layer is 20 to 40cm; c, placing the pipeline on the gravel layer, and covering grain-size fine stone or coarse sand with the thickness of 45 to 55cm on the pipeline; d, covering river sand with the covering thickness of 4 to 20cm on the top of the fine stone or coarse sand, and planting plants on the river sand; and e, arranging a drain pipe at a position, which is closest to a rainwater collecting pit of the road, on the gravel layer at the bottom. Due to the adoption of the method, various pipelines can be flexibly arranged according to the distances of different pipelines; and the fine sand is covered on the surface and the plants are planted, so that the embedding depth of the pipelines can be reduced, the excavating detection of the pipelines is facilitated, and the pipelines can be overhauled and replaced by excavating the coarse sand during the overhauling. By arranging the drain pipe, the rainwater can be effectively removed from the coarse sand, and the pipelines can be effectively protected.
Description
Technical field
The present invention relates to a kind of installation method of outdoor pipeline, particularly industrial and mining enterprise are in the method for all kinds of process pipelines of outdoor mounted.
Technical background
Dual mode is generally adopted in the installation of the outdoor all kinds of process pipelines of industrial and mining enterprise at present, and a kind of is direct-burried, and another is an integrated pipe canal, but dual mode all respectively has pluses and minuses.Integrated pipe canal is divided into and can passes through and two kinds of forms of no thoroughfare.Though the passable conduit maintainer can pass through, easy access, replacing pipeline, the scale of construction of this kind pipe trench is big, be generally about 1.8 * 2 meters, and need facilities such as supporting illumination, ventilation, waterproof, draining, also will consider problems such as sedimentation, anti-draining simultaneously, so cost is higher from structure; Unpassable duct is not because of need the consideration personnel passing through, do not need supporting illumination, ventilation equipment, the scale of construction is less relatively, but need facilities such as supporting waterproof, draining, pressing needs above the code requirement need excavate during the maintenance pipeline more than the earthing 30cm, also need consider to lift the work of trench cover, also to consider problems such as sedimentation, anti-draining from structure simultaneously, more loaded down with trivial details, and cost is also higher.Though standard allows ditch, the generation " thermo-pollution " easily altogether with it of water supply and sewerage pipelines such as tap water, Zhong Shui, fire hydrant pipeline.And the employing pipe trench, than higher, rainwater and underground water is accessible pipe duct very easily as outdoor level of ground water, and just loses insulation effect after the immersion of the thermal insulation layer of heating pipeline, needs excavation replacing completely, and the difficult processing of the waterproof of pipe trench.Adopt the direct-burried form changing, need excavate when overhauling, it is higher manually to reach operating cost, and pipeline need carry out waterproof, preservative treatment.
Summary of the invention:
Purpose of the present invention is intended to overcome the defective of prior art, provide a kind of and have direct-burried form and pipe trench form advantage simultaneously, and again can method for installing outdoor process pipelines.
Method for installing outdoor process pipelines of the present invention is at outdoor excavation irrigation canals and ditches, buries pipeline underground, the steps include:
A, ditching, the distance in roadside, the outdoor road of ditch back gauge is a 1-1.5 rice, furrow width 1.5-2 rice;
Rubble place mat macadam is used in the bottom compacting of b, ditch then, and the thickness of macadam is 20-40 centimetre;
C, pipeline is placed on the macadam, microlith or coarse sand with particle diameter on the pipeline cover the 45-55 cm thick;
The top of d, microlith or coarse sand covers with river sand again, and cladding thickness is 4-20 centimetre, plants plant on river sand;
E, waste pipe is set in the nearest position of bottom macadam and road rain water sump.
Tamp with clay around the described ditch of step a.
The particle diameter of the described rubble of step b is 2-5 centimetre.
The microlith of step c or the particle diameter of coarse sand are 0.4-0.6 centimetre.
The described waste pipe of step e is the D100 waste pipe.
There is filtrating equipment described waste pipe of step e and bottom of trench macadam joint.Described filtrating equipment is a kind of in nylon wire and the Stainless Steel Cloth.
Method for installing outdoor process pipelines of the present invention, during trench, limes marginis is if original soil, the words that the disturbance that is subjected to during excavation is less, then needn't tamp, if limes marginis is a backfill,, then should carry out compacting for preventing the sedimentation inequality, compacting is to tamp with clay around the ditch, the distance in roadside, the outdoor road of ditch back gauge is a 1-1.5 rice, then is to roll a set safe distance in order to prevent that vehicle may cause pipeline on the road, can not have influence on the construction of roadbed simultaneously when construction.Furrow width 1.5-2 rice then is in order to satisfy the code requirement of various pipes direct-burried.After the bottom of trench compacting, carry out place mat with the rubble of 2-5 centimetre of particle diameter, thickness is 20-40 centimetre, the one, and in order to allow pipeline and bottom surface of contact that certain flexibility is arranged, the 2nd, can play the effect of drainage, water can be discharged by waste pipe as early as possible.Cover the microlith or the coarse sand of 0.4-0.6 centimetre of particle diameter on the pipeline, cladding thickness is 45-55 centimetre, can play the effect of protection on the one hand to pipeline, be the zone that can in time be packed into sinking when soil layer generation uneven settlement on the other hand, and assurance pipeline surface of contact enriches and do not deform; Can favourablely overhaul in addition, change, the excavation when increasing pipeline.Cover 4-20 centimetre river sand at the top, and on river sand, plant plant, when playing the greening effect, can also prevent effectively that foreign matter from infiltrating in the coarse sands layer to river sand, plant plant on river sand, easily monoblock takes away or restores, and so also is to help very much maintenance.The position nearest at bottom macadam and road rain water sump is provided with waste pipe, and the nylon net filter device is arranged at waste pipe and bottom of trench macadam joint, waste pipe can be in time drains into the water on upper strata in the road rain water sump, and filtrating equipment can prevent that then coarse sand from flowing into Storm Sewer Network and resulting in blockage.Method for installing outdoor process pipelines of the present invention is filled out coarse sand in the pipe trench, the pipe end adds the rubble compacting, has avoided the settlement issues of pipe trench in the backfill soil, can flexibly, arrange all kinds of pipelines according to the spacing of different pipelines simultaneously.Fill out coarse sand in the pipe trench, surface coverage fine sand kind grass can reduce the buried depth of pipeline, and the excavation of favourable pipeline detects, and only needs when needing excavation the lawn, top layer is removed, and the excavation coarse sand can overhaul, change pipeline.In the place of collecting well near rainwater waste pipe is set, can effectively gets rid of the rainwater in the coarse sand, effectively protect pipeline.
