Abstract
The utility model relates to a kind of syndeton of soft foundation indoor and outdoor gravity current pipeline, comprise indoor drainage pipe and outdoor drainage pipe, described outdoor drainage pipe diameter is greater than indoor drainage pipe diameter, what the outlet side of described indoor drainage pipe inserted described outdoor drainage pipe enters end, the inside of described indoor drainage pipe and outdoor drainage pipe junction is provided with hermetically-sealed construction, and described hermetically-sealed construction comprises pitch ointment plugged zone, is located at the pitch fiber crops stone packed layer below pitch ointment plugged zone and is located at the water proof rubber circle below pitch fiber crops stone packed layer; The outside of described indoor drainage pipe and outdoor drainage pipe junction is provided with dubbin burlap winding layer.Firm ground is relied on completely, by reducing differential settlement to the risk of pipeline damage to the process of pipeline connected mode in order to weaken pipe-line system.
Description
Technical field
The utility model relates to construction work, especially a kind of syndeton of soft foundation indoor and outdoor gravity current pipeline.
Background technology
Using weak soil as the pipeline of soil supporting layer, if pipeline connection is improper, is easy to due to the uneven sedimentation of reason of ground and causes pipeline and interface because being out of shape the excessive seepage that causes, pipeline and interface when serious, can be caused to break.Due to organic in soft foundation, humus is more, comparatively strong to corrosive pipeline under long-time, destroys the stability of pipeline.In pipe works practice, corrosive pipeline and uneven settlement of foundation are two topmost reasons of pipeline damage.Current existing construction technology is attached most importance to consolidation soft foundation, to reduce uneven settlement of foundation, and the connection of pipeline then (flange in a usual manner, socket joint etc.) process, once ground is destroyed, the danger of pipeline damage significantly strengthens, and increases the maintenance management cost risk in later stage.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of syndeton of soft foundation indoor and outdoor gravity current pipeline, can reduce the impact of soft foundation differential settlement on pipe-line system.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of syndeton of soft foundation indoor and outdoor gravity current pipeline, comprise indoor drainage pipe and outdoor drainage pipe, described outdoor drainage pipe diameter is greater than indoor drainage pipe diameter, what the outlet side of described indoor drainage pipe inserted described outdoor drainage pipe enters end, the inside of described indoor drainage pipe and outdoor drainage pipe junction is provided with hermetically-sealed construction, described hermetically-sealed construction comprises pitch ointment plugged zone, be located at the pitch fiber crops stone packed layer below pitch ointment plugged zone and be located at the water proof rubber circle below pitch fiber crops stone packed layer, the outside of described indoor drainage pipe and outdoor drainage pipe junction is provided with dubbin burlap winding layer.Firm ground is relied on completely, by reducing differential settlement to the risk of pipeline damage to the process of pipeline connected mode in order to weaken pipe-line system.
As improvement, described indoor drainage pipe comprises indoor drainage transverse tube and indoor drainage standpipe, and described outdoor drainage pipe comprises outdoor drainage transverse tube and outdoor drainage standpipe, and described outdoor drainage transverse tube is telescoping tube.The design of telescoping tube has reserved space to foundation settlement.
As improvement, described outdoor drainage transverse tube outlet side is connected with manhole, and described outdoor drainage transverse tube dips down down towards outlet side, can reduce the draining adverse slope phenomenon that sedimentation causes.
The beneficial effect that the utility model is compared with prior art brought is:
The junction of indoor drainage pipe and outdoor drainage pipe is provided with pitch ointment plugged zone, pitch fiber crops stone packed layer and water proof rubber circle, not only good seal performance, and can reduce the impact that soft foundation differential settlement connects pipe-line system.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Detailed description of the invention
Below in conjunction with Figure of description, the utility model is described in further detail.
As shown in Figure 1, a kind of syndeton of soft foundation indoor and outdoor gravity current pipeline, comprises indoor drainage pipe 1 and outdoor drainage pipe 2; Described indoor drainage pipe 1 comprises indoor drainage transverse tube and indoor drainage standpipe, and described outdoor drainage pipe 2 comprises outdoor drainage transverse tube and outdoor drainage standpipe, and described outdoor drainage transverse tube is telescoping tube.Described outdoor drainage pipe 2 diameter is greater than indoor drainage pipe 1 diameter, what the outlet side of described indoor drainage pipe 1 inserted described outdoor drainage pipe 2 enters end, described indoor drainage pipe 1 is provided with hermetically-sealed construction with the inside of outdoor drainage pipe 2 junction, and sealing structure is between indoor drainage pipe 1 and outdoor drainage pipe 2.The water proof rubber circle 6 that described hermetically-sealed construction comprises pitch ointment plugged zone 4, is located at the pitch fiber crops stone packed layer 5 below pitch ointment plugged zone 4 and is located at below pitch fiber crops stone packed layer 5; Pitch ointment plugged zone 4, pitch fiber crops stone packed layer 5, water proof rubber circle 6 three-layered node are combined, and have good anti-bending strength and sealing performance.Described indoor drainage pipe 1 is provided with dubbin burlap winding layer 3 with the outside of outdoor drainage pipe 2 junction.Described outdoor drainage transverse tube outlet side is connected with manhole, and described outdoor drainage transverse tube dips down down towards outlet side, can reduce the draining adverse slope phenomenon that sedimentation causes.The position connecting manhole should retain the surplus of sedimentation and deformation, at outdoor drainage pipe 2 junction and turning, increases pipe manhole, regularly monitors, convenient for maintaining, reduce the loss.
Firm ground is relied on completely, by reducing differential settlement to the risk of pipeline damage to the process of pipeline connected mode in order to weaken pipe-line system.
