Abstract
The utility model relates to a glass reinforced plastic sand pipe which comprises a pipe body comprising an outer protection layer, an outer winding layer, a sand layer, an inner winding layer, an anti-seepage layer and an inner protection layer which are bonded in sequence from outside to inside, and a spiral reinforcement sheet which is arranged on the outer side of the outer protection layer, axially extends along the pipe body and is connected with the outer protection layer. As the spiral reinforcement sheet is arranged outside the outer protection layer, the strength of the glass reinforced plastic sand pipe is greatly enhanced. Compared with the prior art that reinforcement ribs are axially arranged along the pipe body, the glass reinforced plastic sand pipe is better in strength in the circumferential direction of the whole pipe body.
Description
Technical field
The utility model relates to pipeline field, particularly relates to a kind of glass reinforced plastic sand pipe.
Background technique
At present, glass reinforced plastic sand pipe, with its excellent decay resistance, waterpower feature, the advantage such as feed flow is large, easy for installation, the duration is short and the comprehensive method of investment is low, becomes the optimal selection of chemical engineering industry and drainage works; But a little less than the low and shock resistance of most of glass reinforced plastic sand pipe compressive strength, therefore most of glass reinforced plastic sand pipe frangibility.
Model utility content
The purpose of this utility model be to provide a kind of simple in structure, intensity is high, the glass reinforced plastic sand pipe of frangibility not.
For solving the problems of the technologies described above, as an aspect of the present utility model, a kind of glass reinforced plastic sand pipe is provided, has comprised: body, body comprises from outside to inside bonding successively external protection, outer wrap, burning into sand layer, interior winding layer, impervious barrier and inner protective layer; Spiral reinforced sheet, spiral reinforced sheet is arranged on the outside of external protection, and spiral reinforced sheet extends axially along body, and spiral reinforced sheet is connected with external protection.
Further, the two ends of body are respectively arranged with adpting flange.
Further, one end of body is provided with internal thread, and the other end of body is provided with outside thread.
Further, external protection is bellows.
Due to the outer installment at external protection spiral helicine spiral reinforced sheet; therefore; greatly increased the intensity of glass reinforced plastic sand pipe, axially arranged compared with stiffening rib along body with of the prior art, the utility model circumferentially has better intensity whole body.
Brief description of the drawings
Fig. 1 has schematically shown structural representation of the present utility model.
Reference character in figure: 1, spiral reinforced sheet; 2, impervious barrier; 3, interior winding layer; 4, burning into sand layer; 5, outer wrap; 6, external protection; 7, inner protective layer.
Embodiment
Below embodiment of the present utility model is elaborated, but the multitude of different ways that the utility model can be defined by the claims and cover is implemented.
Please refer to Fig. 1, the glass reinforced plastic sand pipe in the utility model, comprising: body, and body comprises from outside to inside bonding successively external protection 6, outer wrap 5, burning into sand layer 4, interior winding layer 3, impervious barrier 2 and inner protective layer 7; Spiral reinforced sheet 1, spiral reinforced sheet 1 is arranged on the outside of external protection 6, and spiral reinforced sheet 1 extends axially along body, and spiral reinforced sheet 1 is connected with external protection 6.Preferably, external protection 6 is bellows.
Due to the outer installment at external protection 6 spiral helicine spiral reinforced sheet 1; therefore, greatly increased the intensity of glass reinforced plastic sand pipe, axially arranged compared with stiffening rib along body with of the prior art; the utility model circumferentially has better intensity, not a frangibility whole body.
Preferably, the two ends of body are respectively arranged with adpting flange.Especially, glass reinforced plastic sand pipe also comprises guard ring, and guard ring has protector, and guard ring is stuck in the edge of adpting flange, and is connected with adpting flange by bolt.
Preferably, one end of body is provided with internal thread, and the other end of body is provided with outside thread.
Preferably, the number of spiral reinforced sheet 1 is two, and described two spiral reinforced sheets 1 arrange abreast.What is called arranges abreast, refers to two constant gaps between spiral reinforced sheet 1, remains unchanged.Like this, can further improve intensity.
In one embodiment, outer wrap 5 and interior winding layer 3 can be made up of glass fibre, and inner protective layer 7 can be made up of resin, and impervious barrier 2 can be made up of pitch.
The foregoing is only preferred embodiment of the present utility model, be not limited to the utility model, for a person skilled in the art, the utility model can have various modifications and variations.All within spirit of the present utility model and principle, any amendment of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
