Description
Technical field
The utility model relates to a kind of pipeline balance case, and particularly one is applicable to various geological condition, making, convenient transportation, and can reusable pipeline balance case.
Background technique
When pipeline passes through all kinds of waters such as rivers, lake with digging mode, pipeline can be subject to buoyancy of water effect and produce On The Floating, if can not effectively address this problem, and the lighter's pipeline stress deformation thus lose using function; Severe patient directly will cause pipeline damage, causes delivered inside dielectric leakage thus causes great impact and loss to people's lives, social environment and national economy.Therefore, the anti-flotation issue of pipeline is more and more subject to the attention of each side.
Conventional anti-floating scheme is based on " pressure is floating ", and " the counterweight method " that be namely commonly called as, by increasing the load of pipeline, thus suppresses pipeline to float.Traditional way generally has two kinds, the first, with concrete, reinforcing bar for raw material, first mfg. moulding die, then by the netted structure installment of reinforcing bar that colligation is good in mould, concreting, after maintenance is shaping, be transported to scene, be installed on pipeline afterwards, this method is commonly referred to " concrete weight coating "; The second, with prefabricate equilibrium pressure bag for carrier, after the material of filling sand or small particle diameter, be transported to scene, be lifted on pipeline, this method claims usually " equilibrium pressure bag counterweight ".It is as follows all to there are some problems in these two kinds of counterweight measures:
For concrete weight coating: (1) production time is long, from molding to being finally installed on pipeline, at least need 35 days.(2) maintenance difficulty, for ensureing the quality of final finished, had both needed broad place between curing time, ensured that humidity, temperature and other various factorss are suitable again, particularly in the winter time, build brooder protected.(3) be not easy to direct installation, shaping concrete product, when lifting, for ensureing that pipeline is not scratched, need wrap up the rubber plate of one fixed width, being unfavorable for the position of Reasonable adjustment briquetting in this case, easily occurring laying particular stress on phenomenon on pipeline.(4) producing waste disposal in working process gets up very difficult, to environment.(5) unnecessary concrete block is not easy to be recycled yet, is a kind of waste economically.
For equilibrium pressure bag counterweight: (1) bag many employings polypropylene is raw material, the winter hardiness of this material own is poor, the effect of easy light, heat and oxygen and aging, require that filling should be installed after completing in time, earthing is buried afterwards, but pass through for the waters of pipeline, by the impact of various condition element, this requirement is difficult to realize.(2) because bag Material Strength is low, can not load the materials such as oarse-grained stone, the riverbed for ovum/gravel class can not adopt original soil to load, on the spot sieve soil or outsourcing is native all can increase construction cost.
Model utility content
For solving the problems of the technologies described above, the purpose of this utility model is: provide a kind of pipeline balance case, it can be applicable to various geological condition, making, convenient transportation, and can reuse.
For achieving the above object, the technological scheme that the utility model adopts is:
A kind of pipeline balance case, comprise casing and suspender belt, described casing be top gradually lower portion shrink arch-shaped, wherein, the bottom of described casing is provided with a pipe hole, and pipeline is positioned at the below of pipe hole and is inscribed within the inwall of described pipe hole, the two ends of described pipe hole inwall are outside and continuation downwards extends each formation pressure pipe leg inwall, each pressure pipe leg inwall to the direction away from pipeline upwards bending form the bottom of semi-circle, described bottom outwards also upwards extends to form pressure pipe leg outer wall, the height of described pressure pipe leg outer wall is higher than the inwall of pipe hole, described pipe hole inwall, pressure pipe leg inwall, bottom, pressure pipe leg outer wall and two sidewalls form top and have the casing that opening has holding space.
Described pipeline balance case, described pressure pipe leg outer wall is positioned at opening and is all provided with two suspender belt mounting holes, and described suspender belt is through in suspender belt mounting hole.
Described pipeline balance case, the material of described casing is glass fibre reinforced plastics.
Described pipeline balance case, the material of described casing is engineering plastics.
Described pipeline balance case, the material of described casing is Steel Skeleton and high density polyethylene (HDPE), and high density polyethylene (HDPE) described in one deck is all wrapped up in the inside and outside of described Steel Skeleton.
Compared with prior art, the utility model has the advantage of of technique scheme is adopted:
1, the utility model is lightweight, uncovered box structure, can stack the scene of being transported to after dispatching from the factory.Meanwhile, exceed the partially recycled of consumption and also facilitate, can reuse again.
2, the utility model is the casing be made up of the combination of glass fibre reinforced plastics, engineering plastics or Steel Skeleton and high density polyethylene (HDPE), casing intensity is large, wear-resisting, corrosion-resistant, be applicable to various fresh water type location, little by the restriction such as riverbed geology, execution conditions, to passing through stone river bed rivers and canals under boulder and cobble/block stone river bed rivers and canals, upper soil, and the pipeline of part mountain area rivers and canals/coombe etc. can play good ballast and firmly acts on.
3, the utility model is excellent in cushion effect, to the weight material kind of loading without particular/special requirement, can be sand, stone etc., can choose according to on-the-spot or neighbouring existing situation.
4, the utility model is easy for installation, first can be installed to weight material that pipeline recharges, also be installed to again on pipeline after can loading weight material, can adjust at any time, install according to the waters stressing conditions of reality in a word, there will not be balance weight tilt problem, and allow pipeline to have slight movement.
5, the material that the utility model is selected can not impact site environment, is not also afraid of photo-thermal irradiation, long service life.
