Description
Technical field
The utility model belongs to river row's deposit technique field, and silt system is arranged more particularly to a kind of relay type river.
Background technology
Row's silt work for city river has following features, i.e. river course periphery usable land is deficient, can not provide long-term
, the hydraulic reclamation area that the soil of bulk is as desilting, sludge treatment place concentrates, do not disperse, and in the case that desilting mileage is larger,
Desilting array pitch can be caused to become big.
Haihe River engineering depth of water is shallower, more bridges on river course, and strand suction ship can not construct and transition.And use hydraulicking unit
Desilting is carried out, its capital equipment is slush pump.Slush pump array pitch is shorter, typically within 300m, can not meet the clear of long array pitch
Become silted up and require.It is therefore necessary to study a kind of effectively to solve the problems, such as row's silt scheme of mud long distance delivery.
The content of the invention
The utility model aims to solve the problem that the live receipt part limitation of row's silt in the prior art and can not carry out what row over long distances was become silted up
Technical problem and providing a kind of can effectively carry out row over long distances and become silted up, require that site condition low relay type river row is become silted up system
System.
The utility model is adopted the technical scheme that to solve technical problem present in known technology：A kind of relay-type
Arrange silt system in river, it is characterised in that：Including main desilting tube road, relay pump, collect joint, branch's desilting tube road, eight mud
Pump and two cofferdam；Mud area is molded between two cofferdam；Eight slush pumps are along the longitudinal uniform cloth in the mud area
If eight slush pumps are connected by branch's desilting tube road with the main desilting tube road respectively, branch's desilting tube
Road collects fittings with the main desilting tube road by described, and the joint that collects is provided with eight branches of control respectively
The stop valve in desilting tube road；The relay pump is in tandem on the main desilting tube road.
The utility model can also use following technical measures：
The distance between the slush pump and the relay pump are less than 250m.
The utility model has the advantages and positive effects of：
The utility model can realize that the long range row of mud is become silted up, simple in construction, be limited by the condition of row's silt job site
It is small, and arrange silt efficiency high.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the structural representation for collecting joint in the utility model.
In figure：1st, main desilting tube road；2nd, relay pump；3rd, joint is collected；4th, branch's desilting tube road；5th, slush pump；6th, cofferdam；
Embodiment
For invention, features and effects of the present utility model can be further appreciated that, following examples are hereby enumerated, and coordinate
Accompanying drawing describes in detail as follows：
Refer to Fig. 1 and Fig. 2, a kind of relay type river arranges silt system, including main desilting tube road 1, relay pump 2, collects and connect
First 3,4, eight, branch's desilting tube road slush pump 5 and two cofferdam 6.
Mud area is molded between two cofferdam 6.Eight slush pumps 5 are uniformly laid along mud area longitudinal direction,
Eight slush pumps 5 are connected by branch's desilting tube road 4 with the main desilting tube road 1 respectively.Branch's desilting tube
Road 4 is connected with the main desilting tube road 1 by the joint 3 that collects, and the joint 3 that collects is provided with described in control eight respectively
The stop valve in branch's desilting tube road 4.The relay pump 2 is in tandem on the main desilting tube road 1.
In the present embodiment, relay pump matches as follows with the production capacity of slush pump：
Relay pump highest clear water flow used in engineering is 1800m3/h, and during array pitch 2000m, actual clear water flow is
1600m3/h.Clear water flow is 200m3/h when slush pump array pitch used is less than 250m.During construction, mud distinguishes segment length control
System is within 500m, and slush pump array pitch is controlled within 250m, and relay pump array pitch is usually no more than 2000m, therefore eight mud
Pump can match a relay pump construction, and production capacity can match.
Effect of Interest Rate during desilting
Generally, during more desilting equipments series connection desilting, when interest rate by each desilting equipment joint effect.Will be every
The desilting equipment of one link is divided into 1 unit, wherein after 1 unit can not be matched with other units, you can influences
Interest rate when overall.Illustrated with the utility model, do not consider the situation of 2 relay pumps of series connection, share 2 units, unit 1 is eight
Slush pump, unit 2 are relay pump.Assuming that the when interest rate of unit 1 is a, the when interest rate of unit 2 is b, then interest rate theory when overall
On should be a*b.
In the present embodiment, the caliber of relay pump is 400mm, much larger than the caliber of slush pump, therefore after relay pump places,
Unless the factor such as mechanical breakdown or weather influence, will not be influenceed and be stopped work by working condition substantially, i.e., relay pump when interest rate it is larger,
Typically more than 90%.The key of problem is the when interest rate for improving slush pump, can ensure interest rate during entirety.
Interest rate is mainly influenceed by debris during slush pump, and by optimizing impurity removal process, interest rate can reach during separate unit slush pump
90%.According to being tested before construction, when the slush pump of operation simultaneously can reach 5, relay pump can run well, and
Consumed to reduce, a relay pump is matched using eight slush pumps in the utility model, unless more than four slush pumps stop simultaneously
Work can cause relay pump to be stopped work, and other times can be produced, and this probability is smaller.Generally speaking, the when interest rate of unit 1
Substantially 80% can be reached, interest rate is more than 70% when overall.
