Description
Technical field
The present invention relates to a kind of soil sampler soil basketing method, belong to geotechnical investigation field in civil engineering.
Background technology
What existing soil sampler adopted is cylindric soil sampler, adopts static pressure or hammering method.When soil sampler presses down, soil enters in soil sampler from soil sampler lower ending opening, and the shortcoming of this soil sampler is that soil sampler is in the time pressing down, and because the wall that fetches earth is to native frictional force, adopted soil sample is produced to certain influence, particularly weak soil, and sample rate is lower.For the soil of flow regime, between soil sample and soil sampler, there is relative sliding, cause the height to taking out soil sample and be pressed into soil sampler height have larger difference, be difficult to determine the actual grade of soil sample.Meanwhile, existing soil sampler height is generally less than 50cm, once can only get a soil sample.Cement mixing pile carries out cement dose while detecting, does not need to get undisturbed soil but requirement obtains the soil sample of whole depth boundses, can adopt soil basketing method of the present invention once to adopt the soil sample in whole depth boundses.
Summary of the invention
In order to solve the problem that can not accurately extract target depth soil sample in current sampling process, develop a kind of tubulose air bag envelope and opened side opening soil sampler.This soil sampler is applicable to cement mixing pile, can within the scope of designated depth, fetch earth and the actual grade of definite soil sample, and soil sample is non-undisturbed soil, can be used for carrying out basic physical property analysis and definite clay distribution of soil.
For realizing above-mentioned target, the invention provides a kind of soil sampler device and soil basketing method thereof, a kind of tubulose air bag envelope opens side opening soil sampler, it is characterized in that: described soil sampler is the tubulose detachable fabricated structure of pipe that fetches earth, the described tubulose pipe that fetches earth comprises that some joints pipe middle node and joint Guan Shoujie that fetches earth that fetches earth is formed by connecting by jointing;
The described tubulose pipe that fetches earth comprises the tube body that fetches earth, equidistantly in the described tube body that fetches earth be provided with some lateral partitions, between described every two lateral partitions, form a chamber, in the tube body that fetches earth described in correspondence, on the pipe sidewall of each chamber, have tube wall side opening; In going back in the each chamber forming between described every two lateral partitions, be embedded with an air bag, between above-mentioned air bag, be communicated with connection by tracheae, the two ends of the air bag that described connection links together are provided with valving.
Described tube wall side opening is the rectangular aperture that split both sides, and described lateral partitions is arranged on 5 ~ 10cm place, below of described each rectangular aperture.
Fetch earth pipe middle node, a joint of described some joints fetches earth and is threaded connection between Guan Shoujie and jointing; The described tubulose pipe sidewall that fetches earth indicates scale.
The soil basketing method that described tubulose air bag envelope opens side opening soil sampler comprises the steps:
The first step: inflation, when described air bag is full of after gas, close two ends valving, soil sampler, in closure state, adopts the reaction frame of static sounding that soil sampler is pressed in soil;
Second step: utilize will fetch earth pipe middle node and the Guan Shoujie that fetches earth of jointing to assemble, and adopt the reaction frame of static sounding that the pipe middle node that fetches earth assembling is pressed down with the Guan Shoujie that fetches earth, so repeat the adjunction middle node pipe that fetches earth, until soil sampler presses to designated depth;
The 3rd step: bleed, close two ends valving, the gas in air bag is drawn out of, the tube wall side opening on soil sampler sidewall, in opening, leaves standstill 15 ~ 30min and makes the soil sample of the corresponding degree of depth enter soil sampler;
The 4th step: after having sampled, inflation, closes two ends valve and make soil sampler in closure state after inflation again, utilizes reaction frame that soil sampler is proposed from soil;
The 5th step: according to the scale of every joint soil sampler, determine the actual grade of soil sample.
Advantage of the present invention: a kind of tubulose air bag envelope opens side opening soil sampler, make full use of the mobility of cement mixing pile weak soil, adopt side to enter native mode, can once get the degree of depth of also determining exactly soil sample in target depth range at interval of all soil samples of 10 ~ 20cm, overcome the shortcoming of the thinner soft layer of not high, the easy omission of sampling rate while entering soil from soil sampler lower end.Soil basketing method processing ease of the present invention, only needs to control and gets airbag apparatus and can realize envelope and open sidewall opening, fetches earth efficient and convenient.Therefore soil basketing method of the present invention can be used as the special-purpose taking indigenous method that utilizes tubulose air bag envelope to open side opening soil sampler fast detecting cement mixing pile different depth cement factor and judge clay distribution.
