Abstract
The invention discloses a drainage material assembly capable of being transversely connected with plastic drainage boards and a method for constructing the drainage material assembly, and belongs to the field of buildings. The method includes forming permeable holes on rigid pipes by means of perforation; wrapping the rigid pipes by filter cloth; forming certain quantities of drainage ports of the plastic drainage boards on the pipe walls at different depths; sealing the drainage ports by sealing rings and then connecting the drainage ports with the plastic drainage boards to form transverse drainage channels; further forming three-dimensional drainage materials. The rigid pipes are used as vertical drainage pipes. The drainage material assembly and the method have the advantages that the three-dimensional drainage materials can be arranged in to-be-processed ultra-soft soil by the aid of drainage material press-in forms, so that the drainage distances of processed soil can be shortened, the engineering construction periods can be shortened, and reinforcement effects can be improved; vertical drainage main pipes of the drainage materials can be selectively recycled after construction, so that the construction manufacturing cost can be reduced.
Description
Technical field
The present invention relates to carry out soil body stabilization by drainage using displacement hull, belong to building field.
Technical background
As development especially " 12 " planning outline of China's economic construction is proposed after propulsion marine economy development, edge
Haicheng City is necessarily lifted for the requirement of border on the sea land-based area area and development rate, causes the quantity and exploitation speed of reclamation engineering
Degree also fast development.Traditional reclaiming land around sea is typically adopted based on sand material, but by environmental protection, water conservancy safety and sand material price
Affect and yield.At present filler used by China's reclamation engineering is most of oozes for muck soil or organic matter clay etc. are weak
Permeability, high saturability, low-intensity, high rheological variation weakness barged-in fill based on, in the short time after the completion of hydraulic reclamation the land-based area soil body because
Its moisture content is high, and intensity and bearing capacity are extremely low and can not in time carry out the relevant treatment of ground.Additionally, China's cruiseway lake
Pool can all produce every year substantial amounts of dredging silt, and desilting mud long-time is stacked to dry and existed necessarily to environment and land used resource
Pollution and waste.
For the reclamation engineering of blowing-filling sludge soil, need to be to its advance drainage sunk well of superficial layer super soft weak soil to shape
Into the crust layer with some strength and thickness；For the dredging silt in stockyard, then need that it is carried out drainage sunk well to reduce
Soil moisture content.To sum up, above engineering problem is core is how quickly to reduce the moisture content of superficial layer mud.
At present, in reclamation engineering mainly there be the Treatment Methods of superficial layer ultra-soft soil：Firstth, natural drying：The method one
As dry and at least need 1 year and easily affected by weather, efficiency of construction is very low.Secondth, in floating platform or in advance, laying geotechnique knits
Shallow-layer process deep vertical plastic draining board combined vacuum preloading method is manually plugged on thing or grid carries out drainage sunk well, because of mud
High-moisture percentage and hypotonicity, typically need to carry out vacuum preloading 1～3 month, it is general simultaneously because blowing-filling sludge deflection is very big
Logical plastic draining board will produce wide-angle bending so that affect vacuum transmission and drainage channel it is smooth.And dredging silt
Water discharge method mainly by pre-set in stockyard rigidity vertically and horizontally drainage channel vacuum dehydration process is carried out to mud, this
Method can greatly accelerate the drainage rates of mud, but pre-set displacement hull and insert process to mud and there are certain requirements, and process knot
The rigid drainage body of beam reclaims relatively complicated, therefore the method is not suitable for the drainage system of large area barged-in fill or desilting soil.
Additionally, often occur intensity after the soil body is processed in barged-in fill of reclaiming fields from the sea processes engineering being radially distributed in plastic strip plate
, easily there is " native stake " phenomenon in uneven phenomenon, affects treatment effect, and this is single vertical mainly due to the drainage channel in the soil body
Caused by drainage channel.
To sum up, it would be highly desirable to research and develop a kind of rear forced displacement hull rapidly solidified suitable for large area superficial layer super soft weak soil,
To can combined vacuum precompressed it is quick and treatment effect is preferably processed superficial layer super soft weak soil, without pre-setting
And it is easy to use.
