Abstract
The invention discloses a connecting method of plastic trenches. An elastic telescopic joint is disposed between two adjacent sections of the trenches. The telescopic joint is connected with the trenches arranged on the two ends of the same. When the plastic trenches expand on heat or contract on cold, the elastic telescopic joint moves with the expansion and contraction, so that the problems that the plastic trenches crack due to expansion and contraction to cause the ground arching can be solved.
Description
Technical field
The present invention relates to the plumbing technical field, be specifically related to the method for attachment of a kind of plastics ground groove.
Background technology
The ground groove is important land drainage facility, and it is widely used on various top drainage engineerings and field irrigation water supply and sewage work.At present, a kind of escape canal (groove) take PVC, PE etc. as main material has appearred both at home and abroad, these products are lightweight with it, easy construction, long-lived characteristics more and more come into one's own, but some problems have also appearred in the product use procedure, as the shrinkage heat of product, rise and cause channel to break, the problems affect and restricted functional performance and the life-span of product such as arch upward on ground.as shown in Figure 5, what on common closed conduct, generally adopt is the expansion coupling with annular rubber parts, this structure is actual is exactly to allow between tubing and pipe fitting retain some gaps, make tubing can be vertically freely movable, rubber parts seals to this gap, but the cross section that sealing is arranged unlike tubing due to canal or groove, so there is no enough ring stiffness, the simple expansion joint structure that adopts the tubing form can cause canal or slot cross-section to can't stand that rubber seal power is out of shape and cause leaking owing to holding, from the characteristics of canal or groove and instructions for use, can not there is the structure that strides across runner.The solution of most is after a segment distance, to adopt the form of crossover sub to change sealed tube into to connect the pipe expansion coupling again, or on construction line, avoid the straight line of long distance to lay as far as possible, or at the inspection hole place, free export is set so that channel energy free-extension, but these ways can cause not attractive in appearance, construct trouble, high in cost of production problem, in conjunction with above-mentioned situation, we develop according to plastic row water channel (groove) handling characteristics the expansion coupling product that is suitable for its use targetedly.
Summary of the invention
The present invention is intended to address the above problem to a certain extent.
For this reason, goal of the invention of the present invention is to overcome the defect of prior art, and the method for attachment of a kind of plastics ground groove is provided.
For achieving the above object, the present invention invents and adopts following technical scheme, the method of attachment of a kind of plastics ground groove, between adjacent two sections ground grooves, be provided with elastic telescopic joint, described expansion coupling is connected with the ground groove at two ends, and when plastics ground groove expanded with heat and contract with cold, elastic telescopic joint was along with the telescopic moving of ground groove, avoid the shrinkage heat of ground groove to rise and cause channel to break, the problem such as arch upward on ground.
One embodiment of the present invention, described expansion coupling are elastic corrugated structure, and flexible effective, cost is cheap.
The present invention further improves and is, the two ends of described elastic corrugated structure are provided with bell and spigot, and described ground groove is inserted in bell and spigot, is linked and packed conveniently.
The present invention further improves and is, the outer cover of described elastic corrugated structure is provided with containment vessel, prevents the inflow corrugated portion such as silt, affects the flexible effect of expansion coupling.
The present invention further improves and is, the arranged outside at described elastic corrugated structure two ends has hermetically-sealed construction, and hermetically-sealed construction coordinates with containment vessel, further prevents the inflow corrugated portion such as silt.
Another embodiment of the invention, described expansion coupling are elastic washer, and when plastics ground groove expanded with heat and contract with cold, elastic washer stretched along with the telescopic moving of ground groove, avoid the shrinkage heat of ground groove to rise and cause channel to break, and the problem such as arch upward on ground.
Beneficial effect of the present invention, by on adjacent two sections ground, elastic telescopic joint being set between grooves, effectively overcoming the ground groove and cause channel to break because expanding with heat and contract with cold, and the problem such as arch upward on ground.

Accompanying drawing, only for exemplary illustration, can not be interpreted as limitation of the present invention; For better explanation embodiment, some parts of accompanying drawing have omission, zoom in or out, and do not represent the size of actual product; To those skilled in the art, in accompanying drawing some known configurations and explanation thereof may to omit be understandable.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is described in further details.
As Figure 1-4, the method for attachment of plastics of the present invention ground groove, comprise and two sections plastics ground grooves 4 of adjacent setting during connection, an elastic corrugated structure 1 be set between adjacent ground groove 4.
Concrete, as shown in Figure 2, the two ends of elastic corrugated structure 1 are provided with bell and spigot 11, and ground groove 4 is inserted in bell and spigot 11, and the arranged outside of elastic corrugated structure 1 has containment vessel 3, and the two ends arranged outside of elastic corrugated knot 1 has hermetically-sealed construction 2.
Operating principle of the present invention, when local groove 4 is out of shape because expanding with heat and contract with cold, due to ground groove 4, be inserted in the bell and spigot of ripple struction 1, the masterpiece of this distortion is for ripple struction 1, ripple struction 1 shrinks or stretches under the effect in this distortion, avoid ground groove 4 mutually push or break away from because of distortion, cause 4 breakages of ground groove or leak.Arranged outside in elastic corrugated structure 1 has containment vessel 3, avoids silt to enter in the groove of ripple struction, affects the flexible of ripple struction 1.
The present embodiment and embodiment 1 but are not, the resilient packing ring of apparatus replaces ripple struction.
In accompanying drawing, describe position relationship only for exemplary illustration, can not be interpreted as the restriction to this patent.
Obviously, the above embodiment of the present invention is only for example of the present invention clearly is described, and is not the restriction to embodiments of the present invention.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here exhaustive without also giving all embodiments.All any modifications of doing within the spirit and principles in the present invention, be equal to and replace and improvement etc., within all should being included in the protection domain of the claims in the present invention.
