Abstract
The utility model relates to a cable protecting pipe. Most prior cable protecting pipes are pasted by multi-layer fiber textile through the organic material, which needs more glass fiber textile; therefore, the protecting pipe producing cost is improved and the protecting pipe strength is common. The utility model comprises a pipe body and a linker which are connected into a whole, and is characterized in that the pipe body and the linker are formed by the quartz sand which is arranged in the glass fiber layer. The glass fiber layer is formed by wrapping the circumference of the glass fiber textile. The utility model improves the strength of the cable protecting pipe, reduce the producing cost, and further guarantee the wholeness of the linker and the pipe body.
Description
[technical field]
The utility model relates to a kind of novel cable protection tube that is laid in underground.
[background technology]
When the underground laying cable, want the cable protection pipe of working strength height, easy construction usually.Existing cable protection pipe is bonded by organic material (resin) by the compound glass fabric mostly, and its required glass fabric is more, because the higher protection tube production cost that causes of price of glass fabric is higher.If be embedded in suffered the advocating from circumferential stress of underground protection tube, glass fabric is to be formed by the glass fiber yarn track and column braiding, and the transverse fiber yarn plays a crucial role, and the effect of longitudinal fiber yarn is little, thereby has caused the waste of part longitudinal fiber yarn.
[summary of the invention]
Technical assignment of the present utility model is the defective that addresses the above problem, and provides a kind of intensity higher, lower-cost cable protection pipe.
The technical solution of the utility model is achieved in that a kind of novel cable protection tube; comprise the body and the joint that are connected as a single entity; it is characterized in that described body and joint established quartzy sand bed and constituted by folder in the fiberglass layer, fiberglass layer circumferentially is entwined by glass fiber yarn.Because the modulus of elasticity coefficient of quartz sand has increased the rigidity of cable protection pipe greater than the glass fabric in the fiberglass layer in the quartzy sand bed, under the intensity situation that guarantees protection tube, the thickness of fiberglass layer is reduced.Fiberglass layer thickness reduce and the low price of quartz sand has all reduced the production cost of cable protection pipe; Fiberglass layer adopts single glass fiber yarn circumferentially to be entwined, and has reduced cost, has given prominence to the transverse fiber yarn and has born the effect that circumferential stress plays, and makes the combination between silvalin compact more simultaneously, has improved the intensity of fiberglass layer.
Described a kind of novel cable protection tube, described quartzy sand bed is two layers or more, quartzy sand bed is made up of the quartz sand of even coating; The outside of quartzy sand bed is provided with a fixed bed.Quartzy sand bed is too thick, can make between the quartz sand in the layer in conjunction with not tight, and quartzy being provided with of sand bed of multilayer is resolved the problems referred to above.Fixed bed is a glass fabric, is used for fixing quartz sand, guarantees the stable bond of quartz sand and fiberglass layer.
Described a kind of novel cable protection tube, the axial of the glass fiber yarn in the fiberglass layer and body becomes 50 °-90 °, makes fiberglass layer can bear stress from axial and circumferential like this.
Described a kind of novel cable protection tube, the internal diameter of joint and the external diameter of body adapt, and joint and body are connected smoothly, and have reduced the shear stress of joint and body junction, make stress be tending towards relaxing, and guarantee the globality of joint and body; All use resin bonding between the quartz sand in described each layer, the quartzy sand bed and between the glass fiber yarn in the fiberglass layer.
The utility model has improved the ability to bear of fiberglass layer to circumferential stress, has improved the intensity of cable protection pipe, has reduced cost, has guaranteed the globality of joint and body.
[description of drawings]
Fig. 1 is a cutaway view of the present utility model.
Fig. 2 is the enlarged drawing of A among Fig. 1.
[embodiment]
As shown in Figure 1, 2, the utility model comprises body 1 and the joint 2 that is positioned at the one end, and body 1 is followed successively by interior fiberglass layer 6, quartzy sand bed 5, fixed bed 4 and outer fiberglass layer 3 from the inside to the outside, and described each layer all used resin-bonding.Inside and outside fiberglass layer is that the individual glass fibers yarn circumferentially is entwined, and with resin-bonded, its thickness is 2-5mm between glass fiber yarn.The length of body is generally 4m, and its thickness is 5-12mm.Joint is used for two butt joints between the protection tube, and the internal diameter of joint and the external diameter of body adapt.When making cable protection pipe, become the direction at 60 ° of angles circumferentially to be wrapped on the mould with it with the axial of body glass fiber yarn, form interior fiberglass layer; With resin quartz sand is uniformly coated on interior fiberglass layer then, is wrapped on the quartzy sand bed as fixed bed with the layer of glass fabric again; Become the direction at 60 ° of angles circumferentially to be wrapped on the fixed bed with body axial with it glass fiber yarn at last as outer fiberglass layer, after resin dry, just can be with mould separating.Can between inside and outside fiberglass layer, set up quartzy sand bed, fixed bed and fiberglass layer according to actual needs.
