With can gradually consolidate, while the water being discharged can reuse；
(10), the soil processing after solidifying.
The advantages and positive effects of the present invention are: the present invention completes to cut the earth by the effect that waterpower is cut, then by
Slush pump is filled to large geotechnical pipe bag through mud conveying pipeline, and the conditioner for being suitble to administer the bed mud or steady is added in dredging pipeline
Determine the medicaments such as agent, by pipeline hybrid mode, makes to dredge mud and medicament is sufficiently stirred and generates flocculation group, in geotextile tube band
Middle precipitating reaches the processing that dehydrating and curing is carried out to bed mud.The present invention has continuity, and collection is dredged, conveyed, charging and be integrally turned into
Industry, at low cost, construction efficiency is high；With closure, secondary pollution in transmission process, environmental-protecting performance are solved the problems, such as
It is good；The advantages that construction precision is higher, and effect is preferable, easy to operate, saves working space.The method is abundant by engineering construction example
Demonstrate its exploitativeness and economical.
Detailed description of the invention
Fig. 1 is bed mud dredging process schematic of the present invention；
Specific embodiment
In order to further understand the content, features and effects of the present invention, the following examples are hereby given, and cooperate attached drawing
Detailed description are as follows:
Referring to Fig. 1, a kind of construction method for carrying out the dredging of irrigation canals and ditches bed mud based on hydraulicking filling geotextile tube bag:
(1) interim stockyard construction, carries out clear list processing, by center around according to thousand points in the flattening course of place first
One of ratio carry out slope；Gutter and sump are excavated in stockyard periphery；One layer of 500g/ is laid in bottom after the completion of rolling
The composite geotechnical impervious membrane of ㎡ is laid with the rubble of 30cm thickness on geomembrane, guarantees that the drainage of geotextile tube bag is smoothly discharged.
(2) clear table；The artificial water plant for removing irrigation canals and ditches bottom and house refuse reduce in order to avoid slush pump is easily caused to block
