Description
Technical field
The utility model relates to a kind of plastic drain-pipe and manhole sealing and connecting device, belongs to municipal pipeline equipment technical field.
Background technology
There is the advantages such as tubing is light, interface shape good, easy construction in plastic drainage pipeline comparatively conventional steel bar concrete pipe, therefore use comparatively general in recent years.But plastic drainage pipeline in use, there is following shortcoming: traditional manhole is brick or the rigid structures of steel concrete, plastic pipe is flexible pipe, drainage inspection well and pipe joint place belong to the region that stress is concentrated, under load action, pipeline and well bore inevitably produce inhomogeneous deformation on the one hand, and rigidity well bore produces less distortion, and pipe deforming can be comparatively large, heavy-caliber plastic pipe is particularly serious; Roadbed and manhole also produce differential settlement owing to constructing reason on the other hand, so that poorly base segment is particularly serious, thus cause interface crack.In gutter water level along with the different water-level fluctuations of displacement larger, during abundance of water, infiltration causes ground maceration, and underground water is entrained with the soil body of crack periphery and silt particle enters in pipe from crack during low water, flow away with draining, iterative cycles aggravates, and finally causes the tube circumference soil body to be emptied the serious sinking on road surface that even causes and destroys.Therefore must to occurring that the interface of the problems referred to above is connected and sealed, to ensure sewage, rainwater normal discharge and traffic safety.
Plastic drainage pipeline general at present and the connection of manhole mainly adopt cement mortar, the shutoff of water-swellable sealing ring or soft waterproof casing at interface.But, cement mortar, water-swellable sealing ring interface under unfavorable geological condition, easily because differential settlement and pipe deforming will cause interface crack or seal failure more greatly; Soft waterproof casing is better to rigid conduit waterproof effect, but can not solve the pipe deforming destabilization problems of plastic drain-pipe, and large-caliber drainage pipeline is more outstanding.Therefore, in engineering uses, if because interface bonding strength problem entirety significantly improves large-bore plastics drainage pipe intensity, construction costs can be caused significantly to increase.
Summary of the invention
The purpose of this utility model is to solve drainage inspection well and plastic drain-pipe pipeline joint leaks, problem of misalignment, provide the simple plastic drain-pipe of a kind of structure and manhole sealing and connecting device, this device effectively can strengthen interface plastic drainage pipeline intensity, reduces pipe deforming and strengthens pipe well bonding strength.
The utility model adopts following technical scheme: a kind of plastic drain-pipe and manhole sealing and connecting device, comprise Covered with Angles sleeve pipe and liner short steel pipes, the cavity for holding plastic drain-pipe is provided with between described Covered with Angles sleeve pipe and liner short steel pipes, described Covered with Angles sleeve pipe, sealant is provided with between liner short steel pipes and plastic drain-pipe, the first rubber ring is provided with between described Covered with Angles sleeve pipe and plastic drain-pipe, the second rubber ring is provided with between described liner short steel pipes and plastic drain-pipe, one end of described Covered with Angles sleeve pipe is provided with the first flange socket, one end of described liner short steel pipes is provided with the second flange socket, be bolted on the inwall of manhole between described first flange socket and the second flange socket.
Further, described first flange socket is vertically set on one end of Covered with Angles sleeve pipe, described Covered with Angles sleeve pipe and the first flange socket L-shaped.
Further, described second flange socket is vertically set on one end of liner short steel pipes, described liner short steel pipes and the second flange socket L-shaped.
Further, described Covered with Angles sleeve pipe and liner short steel pipes adopt the mode of socket joint and plastic drain-pipe to connect together.
Further, described Covered with Angles sleeve pipe is cast in the interface of manhole, and the length of described Covered with Angles sleeve pipe exceeds manhole outer wall 300 ~ 500mm, and the length of described liner short steel pipes is identical with manhole wall thickness.
Further, described sealant is the close grout blanket of screed, waterproof mortar course, layer of concrete or polyurethane.
Further, described first flange socket and the second flange socket are single flange socket, and the first flange socket and the second flange socket are dull and stereotyped or circular arc.
Further, described Covered with Angles sleeve pipe and liner short steel pipes adopt carbon steel or stainless steel material to make.
The utility model structure is simple, compact to design, easy to use, waterproof seal is good, ring stiffness is high, non-deformability is strong, quality stability is good, long service life, Covered with Angles sleeve pipe can directly be cast in borehole wall interface, the construction avoiding manhole spare interface to bring is constant and weaken well body structure intensity, is more suitable for the connection of large-bore plastics gutter and manhole, applied range.
