Abstract

The invention relates to multifunctional cleaning solution for pore pressure filter rings for a pore pressure static cone penetration test, which comprises the following components in percentage by mass: 1.00 to 3.00 percent of higher fatty alcohol-polyoxyethylene ether sodium sulfate, 0.50 to 3.00 percent of cocoanut fatty acid diethanolamide, 1.00 to 3.00 percent of ethylene diamine tetraacetic acid (EDTA) disodium, 4.00 to 10.00 percent of organic silicon, 5.50 to 14.00 percent of ethylene glycol and the balance of water. When the pore pressure filter rings for the pore pressure static cone penetration test are cleaned by a Jiekang CD-3800A household small-sized ultrasonic cleaner, the water is injected into the ultrasonic cleaner, a small amount of cleaning solution is added, the pore pressure filter rings needing to be cleaned are put into the ultrasonic cleaner and cleaned for five times at normal temperature and normal pressure for 480s, 380s, 280s, 180s and 90s in turn, and not more than 10 pore pressure filter rings are cleaned each time. The product cannot pollute environment in the using process; cleaning equipment has the characteristics of labor saving, high efficiency and the like, and is environmental-friendly; and a powerful cleaning tool is provided for in-situ pore water pressure static cone penetration test engineering practice.

Description

Static sounding hole press filtration ring scavenging solution is pressed in multi-functional hole

Technical field

The present invention relates to a kind of hole and press static sounding hole press filtration ring scavenging solution, belong to a kind of cleaning liquor in the geotechnical engineering investigation field.

Background technology

Static sounding technology (CPT) is as topmost in-situ testing technique, the advantage that have rapid and convenient, need not take a sample, the image data amount is big, interference is little and expense is cheap, the heavy construction that be particularly useful for motorway, this linear distribution of railway, haves a wide reach.The static sounding technology is meant the sounding rod indentation test soil layer that utilizes pressure assembly will have contact probe, the static point resistance of throughput examining system test soil, sidewall friction resistance etc., can determine some basic physico mechanical characteristic of soil, as the modulus of deformation of soil, the allowable bearing capacity of soil etc.The static sounding technology is the history in existing more than 80 year so far.It is the novel in-situ testing technique that rises in the world the eighties in 20th century that static sounding technology (hereinafter to be referred as CPTU) is pressed in multi-functional hole, compare with the quiet spy of single doube bridge that China is traditional, have theoretical system, multiple functional, advantages such as parameter is accurate, precision is high, good stability.Both can accurately divide soil layer, carry out the great soil group differentiation with the susceptibility that press in super hole, can ask for native in-situ consolidation coefficient, permeability coefficient, kinetic parameter, structural parameter, bearer properties etc. again, be used widely in the civil engineering work design abroad, it is that open holes is pressed element on the basis of traditional static sounding, can survey the pore water pressure in the penetration process, this technology has partly or entirely replaced probing and the sampling in the engineering investigation.When carrying out piezocone test, the hole press filtration ring on the probe all can adsorb a lot of mud at every turn after being used to complete, because filtering ring has microvoid structure, therefore cleans very difficulty; Simultaneously hole press filtration ring cost an arm and a leg and can only dependence on import, buy consuming time oversize.Used filtering ring is reclaimed, carry out second stage employ after cleaning, not only saved but also improved efficient.

Summary of the invention

Technical problem: the technical problem to be solved in the present invention is a cleaning difficult problem of pressing static sounding hole press filtration ring at the hole, and static sounding hole press filtration ring scavenging solution is pressed in the multi-functional hole that proposes a kind of simple and fast.

Technical scheme: multi-functional hole of the present invention presses the mass percent of static sounding hole press filtration ring scavenging solution to be:

High fatty alcohol polyethenoxy ether sodium sulfate: 1.00%～3.00%;

Cocoanut fatty acid diethanolamide: 0.50%～3.00%;

Disodium ethylene diamine tetraacetate (EDTA): 1.00%～3.00%;

Organosilicon: 4.00%～10.00%;

Ethylene glycol: 5.50%～14.00%.

Surplus is a water.

Beneficial effect: the phenomenon of no any contaminate environment takes place in the use of this product, adopts this cover cleaning equipment, has characteristics such as labor-saving, efficient, environmentally friendly, for the engineering practice of original position pore water pressure static sounding provides strong burnisher.

Embodiment

The hole presses static sounding hole press filtration ring washing unit to comprise: clean health board CD-3800A household small-size ultrasonic cleaner and multi-functional CPTU hole press filtration ring scavenging solution.

Multi-functional CPTU hole press filtration ring scavenging solution, its component, quality percentage composition and each component effect are as shown in the table:

When hole press filtration ring is cleaned, in ultrasonic cleaner, inject water earlier, the scavenging solution that will take a morsel is poured in the water, again hole press filtration ring is put into cleanser, and filtering ring is not all had in the entry.After starting the ultrasonic cleaner power supply, set first that scavenging period is 480s, clean and finish the back and take out hole press filtration ring, outwell sewage and the ultrasonic cleaner inwall is cleaned up, carry out cleaning second time.So repeatedly, clean altogether 5 times, each scavenging period successively decreases, and is respectively 480s, 380s, 280s, 180s, 90s.Each hole press filtration number of rings amount of cleaning should not surpass 10, so that cleaning performance reaches best.After cleaning is finished, hole press filtration ring is placed on the shady and cool ventilation place dries up, be immersed in the glycerine saturated wait after the drying and reuse and get final product.Scavenging solution is minimum to skin corrodibility, and volatility is low, therefore can not produce harm to human body, can operate down in the open.

Claims (1)

1. static sounding hole press filtration ring scavenging solution is pressed in a multi-functional hole, it is characterized in that forming this scavenging solution chemical ingredients and mass percent and is:

High fatty alcohol polyethenoxy ether sodium sulfate: 1.00%～3.00%;
