Abstract
The utility model relates to a water discharge pipeline, in particular to a glass reinforced plastic mortar pipe-jacking provided with a spirogyrate connecting ring, comprising a glass reinforced plastic pipe body, a rubber ring and a connecting ring, wherein the inner side of the glass reinforced plastic pipe body is provided with a hollow passage; one end of the glass reinforced plastic pipe body servers as an inserting opening end, while the other end of the glass reinforced plastic pipe body is an inserted opening end which is provided with a ring-shaped concave side provided with a rubber groove inside; the rubber ring is arranged inside the rubber groove; one end of the connecting ring is sleeved on the concave side on the inserted opening end of the glass reinforced plastic pipe body, while the other end of the connecting ring is formed into an inserted opening; the outer diameter of the inserting opening end is corresponding to the inner diameter of the inserted opening. The utility model is characterized in that: the inserted opening end of the glass reinforced plastic pipe body is a convex part. The utility model improves the jacking force bearing capacity of the pipeline and is low in cost.
Description
Technical field
The utility model belongs to the water discharge technology field of the non-excavation pipeline of municipal engineering, is specifically related to a kind of drainage pipe.
Background technology
Glass fiber reinforced steel push pipe with sand in the application in construction of water and wastewater piping engineering more and more widely, its lightweight, high-strength, corrosion-resistant, characteristics obtain more and more insiders' such as the life-span long, top power is little approval.
At present the joint of glass fiber reinforced steel push pipe with sand comprises mainly that the steel collar socket joint connects and the fiber glass reinforced plastic cover rim bearing is inserted and is connected two kinds, and these two kinds of joint forms have a common characteristic: connection collar outer diameter is equal with the pipe shaft outer diameter.Because socket joint is connected spigot rubber groove is arranged, make the tube wall effective thickness reduce, this place is dangerouse cross-section, in order to improve safety stock, increase the ability of bearing ejection force, must increase the tube wall effective thickness, the design concept that equates with the pipe shaft outer diameter according to present this collar outer diameter, certainly will to increase the thickness of homogeneous tube, thus increase cost that can be bigger, and this has limited the application of glass fiber reinforced steel push pipe with sand to a certain extent.
Summary of the invention
At above-mentioned deficiency, the purpose of this utility model is to provide a kind of can improve the low glass fiber reinforced steel push pipe with sand with raised type connection collar of top power, cost that pipeline can bear.
To achieve these goals, the technical solution of the utility model is: have the glass fiber reinforced steel push pipe with sand that raised type connects the collar, it comprises the glass reinforced plastic pipe pipe shaft, rubber ring, connect the collar, in the glass reinforced plastic pipe pipe shaft is cavity passage, one end of glass reinforced plastic pipe pipe shaft is the socket end, the other end is a female end, female end is provided with loop concave, be provided with rubber groove in the loop concave, rubber ring is positioned at rubber groove, the loop concave of one end of the connection collar and the female end of glass reinforced plastic pipe pipe shaft is nested, and the other end that connects the collar forms bellmouth, and the external diameter of socket end is corresponding with the internal diameter of bellmouth; It is characterized in that: the female end of glass reinforced plastic pipe pipe shaft 1 is a protuberance.
The described connection collar is the steel collar or the glass fiber reinforced plastic collar.
The beneficial effects of the utility model are:
1, changes the connection collar outer wall method for designing equal of glass fiber reinforced steel push pipe with sand in the past, when designing and producing the connection collar, will connect the collar and protrude certain thickness (see figure 1) with respect to the pipe outer wall with the pipe shaft outer wall.Regularly increase the effective thickness of female end at pipe shaft wall thickness one on the one hand, thereby can improve the top power that pipeline can bear; Regularly to adopt raised type to connect the pipe shaft thickness of glass fiber reinforced steel push pipe with sand of the collar (female end is a protuberance) thinner than the wall thickness of the general glass fiber reinforced steel push pipe with sand that adopts the collar connecting pipe equal with pipe shaft when top power one on the other hand, thereby can reduce cost.
2, the raised type connection collar can more effectively form slip casting drag reduction annular space, helps the slip casting drag reduction, can further reduce top power.
Description of drawings
Fig. 1 is a structural representation of the present utility model
Among the figure: 1-glass reinforced plastic pipe pipe shaft, the 2-rubber ring, 3-connects the collar (steel collar or the glass fiber reinforced plastic collar), 4-protuberance.
The specific embodiment
Embodiment 1:
As shown in Figure 1, glass fiber reinforced steel push pipe with sand with raised type connection collar, it comprises glass reinforced plastic pipe pipe shaft 1, rubber ring 2, connects the collar 3, in the glass reinforced plastic pipe pipe shaft 1 is cavity passage, one end of glass reinforced plastic pipe pipe shaft 1 is the socket end, the other end is a female end, female end is provided with loop concave, be provided with rubber groove in the loop concave, hydro-expansive rubber circle 2 is positioned at rubber groove, the loop concave of one end of the connection collar 3 and the female end of glass reinforced plastic pipe pipe shaft 1 is nested, and the other end that connects the collar 3 forms bellmouth, and the external diameter of socket end is corresponding with the internal diameter of bellmouth; The described connection collar 3 is a steel collar; The female end of glass reinforced plastic pipe pipe shaft 1 is a protuberance 4.
Embodiment 2:
Substantially the same manner as Example 1, difference only is: the described connection collar 3 is the glass fiber reinforced plastic collar; The loop concave of one end of the glass fiber reinforced plastic collar and the female end of glass reinforced plastic pipe pipe shaft 1 is nested and is bonding.
Claims (2)
1. the glass fiber reinforced steel push pipe with sand that has the raised type connection collar, it comprises glass reinforced plastic pipe pipe shaft, rubber ring, the connection collar, in the glass reinforced plastic pipe pipe shaft is cavity passage, one end of glass reinforced plastic pipe pipe shaft is the socket end, the other end is a female end, female end is provided with loop concave, be provided with rubber groove in the loop concave, rubber ring is positioned at rubber groove, the loop concave of one end of the connection collar and the female end of glass reinforced plastic pipe pipe shaft is nested, the other end that connects the collar forms bellmouth, and the external diameter of socket end is corresponding with the internal diameter of bellmouth; It is characterized in that: the female end of glass reinforced plastic pipe pipe shaft (1) is a protuberance.
2. the glass fiber reinforced steel push pipe with sand with raised type connection collar according to claim 1, it is characterized in that: the described connection collar is the steel collar or the glass fiber reinforced plastic collar.
