Specific implementation mode

The utility model will be further described below in conjunction with the accompanying drawings.

The cyclic annular drainage pipeline networks of the utility model, including drainage pipeline, the drainage pipeline connect into ring-type to each other Formula can connect into cyclic structure by horizontal and vertical setting, and the drainage pipeline intersection is set as node, and the node can It is set as inspection shaft or sump.Each node is at least connected with two drainage pipelines, for a node, when its connection There is one in drainage pipeline when accident occurs, other drainage pipelines that ponding can be connected by this node are discharged.When any When block occurs for node, the ponding of this node is transported to adjacent node by drainage pipeline, and then connected by adjacent node Drainage pipeline is discharged, and sump or inspection shaft block are prevented.Gravity stream is still relied in the drainage pipeline to be drained.

Embodiment one：Cyclic annular drainage pipeline networks --- cyclic annular Storm Sewer Network

Nowadays the Storm Sewer Network of cities and towns laying is dendritic Storm Sewer Network, as shown in Figure 1, whereinIndicate street Road,Indicate drainage pipeline, in figure below similarly.The rainwater that water catchment area is collected passes through row by sump or inspection shaft Waterpipe is discharged into river nearby, and drainage pipeline is single, when the excessive sump of rainfall or inspection shaft ponding, can lead to whole draining Pipeline is paralysed, the problems such as causing Urban Streets ponding.

City Storm Sewer Network is now transformed according to cyclic annular drainage pipeline networks concept, transformation back plan view is shown in Fig. 2.Storm Sewer Network uses Annular configuration is set altogether there are six ring so that each sump or inspection shaft are at least connected with two pipelines, have two paths to be arranged Water.Such as when block occurs for drainage pipeline 8-3, the rainwater that drainage pipeline 8-11 is transferred can pass through the drainage pipeline 7- of lateral connection 8 and 8-9 delivers water into node 7 and 9 respectively, and then is discharged into river by the drainage pipeline that node 1,5 connects, to solve The ponding problem as caused by the sump or inspection shaft block.Equally, when drainage pipeline is damaged, rainwater also can be through node Other connected drainage pipelines transfer transport, substantially increase safety and the timeliness of draining.

The economic problems for considering Sewer Line Distribution construction, further optimize cyclic annular Storm Sewer Network.In main city Area uses looping network, and branched network is used in the small region of suburban population's density.Cyclic annular, dendritic mixing rain-water drainage after optimization Arrangement such as Fig. 3.

The density of population is big in city, and building is concentrated, and hard surface area is big, and amount of seepage is few when rainfall, and draining is main By the discharge of pipes after runoff gathering, laying looping network can improve the safety of draining, while accelerate the speed of draining, Reduce surface gathered water.In suburb position, green coverage is big, sparse population, and rain penetration rate is big, can still be adopted after appropriate adjusting pipe diameter It is drained with branched network.

Embodiment two：Cyclic annular drainage pipeline networks --- cyclic annular sewage network

Sewage network increases main pipe compared with Storm Sewer Network, and the sewage that block is collected drains into main pipe by main pipe connection, passes through It is delivered to the sewage treatment plant in city by main pipe, discharges after treatment.Existing country's sewage network is branched network, is seen below Fig. 4, the sewage in a region are only conveyed there are one main pipe, and safety coefficient is low, when Pipeline damage or inspection shaft block, meeting Cause the drainage system of section to be paralysed, directly affects the production and living of resident.

Now the sewage network in cities and towns is transformed through row is cyclic annular by the concept of looping network, looping network is shown in Fig. 5 after transformation.? Main pipe is added on the basis of existing pipe network, forms looping network, and there are six rings altogether, increase the longitudinal drainage pipe with effect of transferring Road, improved pipe network draining safety are greatly improved.Such as when drainage pipeline 2-6 is damaged, sewage can pass through Transverse drainage duct is transported to the longitudinal drainage pipeline 1-5 and 3-7 closed on and then is discharged in main pipe.Equally work as node block When, sewage can be also discharged by node nearby in pipeline.

Consider economic benefit, cyclic annular sewage network is optimized, is applied in the form of cyclic annular, dendritic combination If arrangement is shown in Fig. 6 after improvement.Densely populated in resident, the big city of quantity of wastewater effluent is made using the arrangement of cyclic annular sewage network It is that can be drained by adjacent conduit that every pipeline, which breaks down, to ensure the safety of draining.Population compared with Few suburb uses branched network, has single line to be drained.When enlargement of cities, municipal drainage pipe network also can accordingly increase Add pipeline, is formed cyclic annular.
