Description
Technical field
The utility model relates to the correlative equipment technical field used in dredging works, particularly relates to a kind of technical field of the armored sludge discharge pipe for dredging works.
Background technique
River course, navigation channel, basin is dredged deeply, shoal, harbour, the mud delivery pipeline that the mechanical dredging engineerings such as harbour foundation trench all need a large amount of sludge drainage pipes to be formed by connecting realizes conveying, and in whole mud delivery pipeline the indispensable sludge drainage pipe for adjusting mud delivery pipeline direction, so far the Self-float mud discharging rubber pipe that always uses of major part, because Self-float mud discharging rubber pipe is being carried as rock, coral reef, ores etc. have during the solid material of sharp-edged and can be worn through very soon, lose use value, and whole dredging works system downtime will be caused, carry out repairing or whole mud delivery pipeline is scrapped, expend valuable engineering time and higher pipeline maintainance expense.For solving this technical problem, technological deficiency existing for further improvement Self-float mud discharging rubber pipe, disclosed in State Intellectual Property Office on 03 02nd, 2011, the patent No. is: the technological scheme of ZL201020214517.8 and December in 2009 notice of authorization on the 02nd the patent No. be: the technological scheme of ZL200920036395.5 is all solve the technological deficiency existed in background technique, improving the technological scheme proposing in wear-resisting property and increase the good organic adhesion agent of wear-resisting property and wear-resisting steel loop at the innermost layer of sebific duct, for the working life of improving Self-float mud discharging rubber pipe provides new technical measures.But the product defect existing due to Self-float mud discharging rubber pipe itself and cause and there is following deficiency: although first Self-float mud discharging rubber pipe has certain bending properties, but because the tortuosity adjusting mud delivery pipeline direction leans on the scheme of bulk deformation from inside to outside to realize, this distortion has come for the resiliently deformable Self-float mud discharging rubber pipe being each position of tube body, and the resiliently deformable at each position is for the same circumferential section of body, there is again the dual stressed of Tension and Compression, thus itself there is certain defect in this technological scheme, particularly when supporting the use with binding type supporting metal sludge drainage pipe shown go out the defect do not matched more outstanding, the wear-resisting property of its two to be Self-float mud discharging rubber pipes by the technological scheme increasing organic adhesion agent and wear-resisting steel loop at the innermost layer of sebific duct improve rubber pipe, when this Self-float mud discharging rubber pipe in use, the solid material be transferred operation again and again in a conveyance conduit be made up of organic adhesion agent and wear-resisting steel loop, the inwall made due to organic adhesion agent and wear-resisting steel loop can by solid material impact several times, the degree of wear of organic adhesion agent and wear-resisting steel loop is different, not only can there is transporting resistance and affect transporting velocity in this, and be difficult to support the use with better metal composite sludge drainage pipe because inner tubal wall wear-resisting property is inconsistent, particularly under operating environment more mal-condition, carry ore, the South Sea conveying coral reef operation time, this phenomenon that do not match just shows more outstanding, therefore, how to design on the basis of existing technology, manufacture a kind of armored sludge discharge pipe both satisfied purposes being used for adjusting mud delivery pipeline direction, can reach again simultaneously and be close with the wear-resisting property of metal composite sludge drainage pipe, the working life of comprehensive raising metal sludge drainage pipe, reduce the cost of production of dredging works, improve Business Economic Benefit, this is for a technical task urgently to be resolved hurrily really those skilled in the art.
