Abstract
The utility model relates to a pipe driving lantern ring which comprises a canister body, the wall of which consists of ring fiber winding layers and axial fiber winding layers which are overlapped in turn. The quantity ratio of the layers between the ring fiber winding layers and the axial fiber winding layers is 1:1 to 4:1 with the ratio of preferred as 2:1. The weight ratio between the ring fiber winding layers and the axial fiber winding layers is 2:1 to 5:1 with the ratio of preferred layers as 2.5:1. As the ring fiber winding layers and the axial fiber winding layers are overlapped in turn, the fiber glass pipe driving lantern ring has good mechanical efficacy, high anti-erosion capability and low fabrication cost.
Description
Technical field
The utility model relates to a kind of pipeline the connection collar, particularly a kind of push pipe collar of glass fibre reinforced plastics material.
Background technique
In the municipal pipeline laying project, dual mode is generally arranged now: a kind of is open heavy excavation, be about to ground and excavate comprehensively, the mutual sheathed connection of pipe is placed down backfill again again, the used pipe of this digging mode is prefabricated, connect and do not bear pressure or top power when laying, but this mode is subjected to concrete environmental limit easily, such as building etc., and heavy excavation method consumes resources is many, and is bigger to the daily life influence in city.For this reason, the mode of another kind of employing push pipe tubing occurred, earlier dug working pit in advance, in working pit with one section one section of push pipe in the jacking forward of underground certain depth position, during this push pipe operation, the Placement of jacking pipeline adopts the collar.
The collar of prior art generally adopts steel part, faces to be embedded in underground etching problem for a long time, must take the secondary preservative treatment, the maintenance cost height.If adopt Stainless Steel Products, price is higher, increases engineering cost.
The model utility content
The purpose of this utility model provides a kind of push pipe collar, effectively solves existing metal roof trunnion ring price height, perishable and maintenance cost high-technology defective.
To achieve these goals, the utility model provides a kind of push pipe collar, comprises a cylindrical shell, and described barrel wall constitutes by folding hoop fiber winding layer and the axial direction fibre winding layer established successively.
Described hoop fiber winding layer is 1: 1～4: 1 with the number of plies ratio of axial direction fibre winding layer.Preferred number of plies ratio is 2: 1.
The weight ratio of described hoop fiber winding layer and axial direction fibre winding layer is 2: 1～5: 1.Preferred weight ratio is 2.5: 1.
On the technique scheme basis, the minimum fiber consumption of described axial direction fibre layer is every square metre 1500 gram.
The utility model push pipe collar is established by the folded successively of hoop fiber winding layer and axial direction fibre winding layer, makes the glass fibre reinforced plastics push pipe collar have the good mechanical performance, and has high corrosion resistance and low manufacture cost.Particularly, the barrel wall of the push pipe collar is made of several hoop fiber winding layers and axial direction fibre winding layer, several hoop fiber winding layers can guarantee that push pipe collar integral body has good hoop intensity, several axial direction fibre winding layers that are folded between the hoop fiber winding layer can improve the buckling strength of the pipeline collar, so make push pipe collar integral body have good bending resistance.
Below in conjunction with accompanying drawing the utility model is done detailed description further.
Description of drawings
Fig. 1 is the structural representation of the utility model push pipe collar.
Embodiment
Fig. 1 is the structural representation of the utility model push pipe collar.As shown in Figure 1, the push pipe collar is a cylindrical shell, and barrel wall is made of several folded successively hoop fiber winding layer 10 and axial direction fibre winding layers 20 of establishing.Wherein, the hoop fiber winding layer is meant the fiber of glass fibre or glasscloth with the layer of fibers perpendicular to the winding of tubular axis direction, and the axial direction fibre winding layer is meant the layer of fibers that the fiber of glass fibre or glasscloth is laid along the tubular axis direction.
The utility model push pipe collar is established by the folded successively of hoop fiber winding layer and axial direction fibre winding layer, makes the glass fibre reinforced plastics push pipe collar have the good mechanical performance, and has high corrosion resistance and low manufacture cost.Particularly, the barrel wall of the push pipe collar is made of several hoop fiber winding layers and axial direction fibre winding layer, several hoop fiber winding layers can guarantee that push pipe collar integral body has good hoop intensity, several axial direction fibre winding layers that are folded between the hoop fiber winding layer can improve the flexural strength of the pipeline collar, so make push pipe collar integral body have good bending resistance.
In the utility model push pipe collar technological scheme shown in Figure 1, hoop fiber winding layer 10 is 8 layers, axial direction fibre winding layer 20 is 4 layers, and each axial direction fibre winding layer 20 is folded in respectively between the hoop fiber winding layer 10, and the number of plies ratio that forms hoop fiber winding layer and axial direction fibre winding layer is 2: 1 a structure.Wherein, outermost, interior and middle hoop fiber winding layer are two layers, the equal individual layer setting of axial direction fibre winding layer.In the utility model, the hoop fiber winding layer can be 1: 1～4: 1 with the number of plies of axial direction fibre winding layer than being, preferred number of plies ratio is 2: 1.In addition, the structure of hoop fiber winding layer and axial direction fibre winding layer can also be set in the weight ratio mode, the weight ratio of hoop fiber winding layer and axial direction fibre winding layer is 2: 1～5: 1, and preferred weight ratio is 2.5: 1.The minimum use amount of the fiber of described axial direction fibre layer is every square metre 1500 gram, to guarantee axial strength.
Should be noted that at last: above embodiment only is not intended to limit in order to the explanation the technical solution of the utility model; Although with reference to preferred embodiment the utility model is had been described in detail, those of ordinary skill in the field are to be understood that: still can make amendment or the part technical characteristics is equal to replacement embodiment of the present utility model; And not breaking away from the spirit of technical solutions of the utility model, it all should be encompassed in the middle of the technological scheme scope that the utility model asks for protection.
