Description

A kind of seabeach of enclosing of jackstone in conjunction with flexiplast drain bar applies roadbed construction method
[technical field]
The present invention relates to the technical field of roadbed, especially a kind of jackstone encloses seabeach painting in conjunction with flexiplast drain bar The technical field of roadbed construction method.
[background technique]
With China's Coastal Areas expanding economy, occur building for more and more " Perioperative cardiac events engineerings " on very long coastline If while be accompanied by a large amount of planning of paralic tide area road, and roadbed is the important component of highway, its construction matter Amount quality directly influences the quality of entire highway engineering.Roadbed is the basis on road surface again, and driving lotus is born on it and road surface jointly The effect of load.There is firm, stable roadbed, must just solve what Coastal beach area road roadbed was formed by " reclaiming fields from the sea " The problem that " upper pine, under soft ", underground water content of soil are abundant, foundation bearing capacity is very poor.
Traditional mudflat sludge roadbed treatment implements piling prepressing using plastic draining board and on plastic draining board top, makes Soft soil foundation void water is from the layer of sand or horizontal plastic drain-pipe that plastic draining board is discharged to top place mat, by arranging elsewhere Out, accelerate concretion of soft foundation.It has the following problems: first, plastic draining board integral strength is not high, vulnerable to soil in drainage procedure Body squeezes, and causes its distortion bending, is obstructed so as to cause the drainage path of plastic draining board, drainage efficiency substantially reduces;Second, It is very long so as to cause the duration that the drainage speed of preloading relies on infiltration coefficient name in water;Third, the reinforcing of mud deep layer Effect is poor, crust layer phenomenon easy to form.
[summary of the invention]
The object of the invention is to solve the problems of the prior art, propose a kind of jackstone in conjunction with flexiplast drain bar Enclose seabeach apply roadbed construction method, can by the first enrockment area mud inner horizontal to mud pressurize, the second jackstone Area vertically pressurizes to mud at the top of mud, accelerates water to enter drain bar by non-woven fabrics absorbed layer, cooperates suction unit Vacuum suction, is discharged the pore water in ground through drainpipe by drain bar, reaches and is displaced closely knit, acceleration ground between soil particle Consolidation with sedimentation effect;By the buffer board and buffer bar of setting elasticity made of rubber, make its compressive deformation, thus Wavy substrate is protected, avoids drain bar draining from being obstructed, improves drainage efficiency;By the upper end two sides cheated in jackstone, steel is set Plate, and jackstone is carried out from centre to two sides, on the ground with some strength, seabeach painting is enclosed in further consolidated subsoil, realization Subgrade construction.
To achieve the above object, the seabeach of enclosing that the invention proposes a kind of jackstones in conjunction with flexiplast drain bar applies roadbed Construction method includes the following steps:
