Abstract
The utility model provides a planomural pipe additional joint for an inspection well. The planomural pipe additional joint for the inspection well is simple in structure, low in cost, stable in sealing and convenient to use during construction. The planomural pipe additional joint for the inspection well comprises an additional joint main body matched with a wall hole of a well barrel of the inspection well in size, wherein a sealed sleeve is arranged between the additional joint main body and the well barrel, the additional joint main body stretches into the inspection well from the wall hole and is in a cylinder shape with a flaring, and a sealed ring for squeezing a planomural pipe is arranged in the flaring. Compared with a saddle-shaped joint, the planomural pipe additional joint for the inspection well can be installed from outside of a pipe, and is convenient to use in construction.
Description
Technical field
The utility model belongs to the plastic conduit construction field, particularly relates to the joint in the plastic conduit construction.
Background technology
For plastic inspection well, according to the directly perforate on the arbitrary height any direction of pit shaft of construction requirement needs scene, connecting pipe is installed.Generally use saddle joint on the market, but the saddle joint part is many, complex structure, and pit shaft length is often longer when construction, after pit shaft ends the hole, the saddle joint main body need to be stretched by the hole of having held successfully from the pit shaft inner surface again and install, and causes constructional difficulties.
Summary of the invention
That the utility model provides is a kind of simple in structure, with low cost, the sealing reliable, the walled tube plus couplings that is used for manhole of easy construction.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of walled tube plus couplings for manhole, comprise the plus couplings main body that is complementary with wall pore size that manhole shaft is opened, be provided with sealing shroud between plus couplings main body and the pit shaft, described plus couplings main body stretches into manhole outside cinclides, the plus couplings main body is the cylindrical shape with enlarging, is provided with the sealing ring of extruding walled tube in the enlarging.The sealing shroud external surface is by extruding and cinclides sealing, and the sealing shroud inner surface is by extruding and the sealing of plus couplings main body external surface.
Further, described sealing shroud is cylindrical shape, and the one end is provided with the first positioning bar of evagination, and inwall is provided with the first reinforcing rib.Further, described the first reinforcing rib is 2 semicircular convex lines.
Further, described plus couplings main body is provided with the second positioning bar of indent away from enlarging one end, and the other angle of the second positioning bar is made as chamfering.
Further, described sealing ring inner surface is provided with the fin that prevents that walled tube from sliding, and external surface is provided with the second reinforcing rib of protrusion.Further, described fin has 3, and described the second reinforcing rib is semicircular convex line.
Compared with prior art, beneficial effect is: walled tube plus couplings provided by the utility model, simple in structure, favorable sealing property can replace the saddle joint on the market, and, different from saddle joint is that plus couplings main body of the present utility model is to stretch into inwall from the manhole outer wall, has greatly reduced difficulty of construction, improved operating efficiency, very large promotional value has been arranged.

The specific embodiment
As shown in Figure 1 and Figure 2, a kind of walled tube plus couplings for manhole, comprise the plus couplings main body 2 that is complementary with cinclides that manhole shaft is opened 51 sizes, be provided with sealing shroud 1 between plus couplings main body 2 and the pit shaft 5, described plus couplings main body 2 stretches into manhole outside cinclides 51, plus couplings main body 2 is the cylindrical shape with enlarging 24, is provided with the sealing ring 3 of extruding walled tube 4 in the enlarging 24.
As shown in Figure 3, described sealing shroud 1 is cylindrical shape, and the one end is provided with the first positioning bar 11 of evagination, and inwall is provided with the first reinforcing rib 12, and described the first reinforcing rib 12 is 2 semicircular convex lines.
As shown in Figure 4, described plus couplings main body 2 is made as chamfering 22 away from the second positioning bar 21, the second positioning bars 21 other angles that enlarging 24 1 ends are provided with indent.
As shown in Figure 5, described sealing ring 3 inner surfaces are provided with the fin 31 that prevents that walled tube from sliding, and external surface is provided with the second reinforcing rib 32 of protrusion, and described fin 31 has 3, and described the second reinforcing rib 32 is semicircular convex line.
When constructing, at first determine the height and direction that connects walled tube 4 after, open cinclides 51 at plastic inspection well pit shaft 5.Then sealing shroud 1 is filled in the cinclides 51 of having held successfully from the pit shaft outside, until the first positioning bar 11 touches the external surface of pit shaft, and then plus couplings main body 2 past sealing shroud 1 interior plugs, until enlarging 24 external surfaces and the first positioning bar 11 compress.Then enlarging 24 the insides that sealing ring 3 are set to plus couplings main body 2, note the direction of fin 31.Insert at last walled tube 4, until the second positioning bar 21 of plus couplings main body 2 installs like this.Sealing shroud 1 and sealing ring 3 all adopt elastomeric material.Because the elasticity of rubber extruding, the plus couplings Soil stability that installs is firm, good airproof performance, sealing shroud 1 external surface is by cinclides 51 sealings of extruding with pit shaft 5, and 2 semicircular the first reinforcing ribs of sealing shroud 1 inner surface are by extruding and the sealing of plus couplings main body 2 external surfaces.
