Abstract
The invention provides a permeability coefficient determinator for a geosynthetic clay liner (GCL), which relates to an instrument for measuring the permeability coefficient of the GCL under the environment of a simulated water channel. The permeability coefficient determinator for the GCL comprises a top plate, a water storage tank, a sample clamping cushion and a water collector, wherein the top plate is fixed on the water storage tank to form a closed space; a water inlet pipe and an exhaust pipe are arranged on the upper part of the top plate; an opening is formed at the bottom of the water storage tank, and a dismountable water passing disk is arranged in the water storage tank; the sample clamping cushion is arranged below the water storage tank; a bottom plate is arranged below the sample clamping cushion, the bottom plate is relatively fixed with the top plate through bolts, and the sample clamping cushion is fixed below the water storage tank; the water collector is fixed below the bottom plate, and a plurality of water leakage holes are formed on the bottom plate and are communicated with the water collector; and a water outlet pipe is arranged below the water collector. The instrument has simple structure, can flexibly simulate water channels under the environment of different heights of water heads, can accurately measure the permeability coefficient of the GCL, and simultaneously can measure similar impermeable materials.
Description
Technical field
A kind of permeability coefficient determinator for geosynthetic clay liner (GCL) relates at the simulation channel and crossing under the water condition, measures the instrument of the infiltration coefficient of GCL.
Background technology
Still there is not this kind equipment at present.
Summary of the invention
The purpose of this invention is to provide a kind of utilization simulation water channel environment, measure the instrument of the infiltration coefficient of GCL.
This permeability coefficient determinator for geosynthetic clay liner (GCL) is to be made of top board, aqua storage tank, sample clamping cushion and the ware that catchments; Top board is fixed on the aqua storage tank, forms an enclosure space; Water inlet pipe and gas outlet are equipped with in top board top, all communicate with aqua storage tank; The bottom of aqua storage tank has mouth, in adorn dismountable water pond of crossing; Be placed with the sample clamping cushion below the aqua storage tank; Under the sample clamping cushion base plate is arranged, base plate is by bolt and top board relative fixed, and the sample clamping cushion is fixed under the aqua storage tank; Be fixed with the ware that catchments below the base plate, have some leaking holes on the base plate, ware communicates with catchmenting; Catchment and rising pipe is housed under the ware; The sample clamping cushion is ring-like, hollow, and interior ring opening, its section are " U " type of lying down.
When this permeability coefficient determinator for geosynthetic clay liner (GCL) uses, unclamp bolt, take out the sample clamping cushion, after measured object is placed in one, be put back between aqua storage tank and base plate, bolt is tightened.The Ma Shi bottle is suspended to certain height, the simulation head height.Water inlet pipe communicates with the Ma Shi bottle by flexible pipe.After aqua storage tank is filled water, gas outlet is sealed.Placing graduated cylinder at last under rising pipe gets final product.Infiltration water by aqua storage tank cross leaking hole on water pond, measured object, the base plate, catchment ware and rising pipe flow in the graduated cylinder.By the water percolating capacity of unit interval, can calculate the infiltration water coefficient.
This instrument adopts the detachable water pond of crossing, and mainly contains to be beneficial to when adopting the bigger Huanghe water of silt content to do permeability test, can be convenient to clean aqua storage tank inside.The sample clamping cushion that adopts in this instrument, anti-sealing was from the seepage at tested sample edge, to guarantee the accuracy of experimental result when it can guarantee the firm grip tested sample.This apparatus structure is simple, can simulate the water channel under the different head height environment flexibly, and can accurately measure this GCL infiltration coefficient.Simultaneously also can measure similar barrier material.
