Description

Tubulose air bag envelope opens side opening soil sampler and soil basketing method thereof
 
Technical field
The present invention relates to a kind of soil sampler soil basketing method, belong to geotechnical investigation field in the civil engineering.
Background technology
What existing soil sampler adopted is cylindric soil sampler, adopts static pressure or hammering method.When soil sampler pressed down, soil got in the soil sampler from the soil sampler lower ending opening, and the shortcoming of this soil sampler is soil sampler when pressing down, and owing to the frictional force of wall to soil that fetches earth, adopting soil sample was produced certain influence, particularly weak soil, and sample rate is lower.For the soil of flow regime, take place between soil sample and the soil sampler to slide relatively, cause to the height that takes out soil sample be pressed into the soil sampler height bigger difference arranged, be difficult to confirm the actual grade of institute's soil sampling.Simultaneously, existing soil sampler height is generally less than 50cm, once can only get a soil sample.Cement mixing pile carries out cement dosage when detecting, and need not 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 accurately to extract the target depth soil sample in the present sampling process, developed a kind of tubulose air bag envelope and opened the side opening soil sampler.This soil sampler is applicable to cement mixing pile, can in the designated depth scope, fetch earth and the actual grade of definite institute soil sampling, and institute's soil sampling 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 the side opening soil sampler; It is characterized in that: said soil sampler is the tubulose detachable fabricated structure of pipe that fetches earth, and the said tubulose pipe that fetches earth comprises and fetches earth some joints segmentum intercalaris and a joint Guan Shoujie that fetches earth are formed by connecting through jointing in the pipe;
Said tubulose fetches earth to manage and comprises the tube body that fetches earth; Equidistantly in the said tube body that fetches earth be provided with some lateral partitions; Form a chamber between said per two lateral partitions, have the tube wall side opening on the pipe sidewall of each chamber in the corresponding said tube body that fetches earth; Be embedded with an air bag in going back in each chamber that forms between said per two lateral partitions, be communicated with connection through tracheae between the above-mentioned air bag, the two ends of the air bag that said connection links together are provided with valving.
Said tube wall side opening is the rectangular aperture that split both sides, and said lateral partitions (10) is arranged on 5 ~ 10cm place, below of said each rectangular aperture.
Segmentum intercalaris, a joint fetched earth between Guan Shoujie and the jointing through being threaded during said some joints fetched earth and manage;
Said tubulose fetch earth the pipe sidewall indicate scale.
The soil basketing method that described tubulose air bag envelope opens the side opening soil sampler comprises the steps:
The first step: inflation, after said air bag is full of gas, close the two ends valving, soil sampler is in closure state, adopts the reaction frame of static sounding that soil sampler is pressed in the soil;
Second step: segmentum intercalaris assembles with the Guan Shoujie that fetches earth in the pipe to utilize jointing to fetch earth; And segmentum intercalaris presses down with the Guan Shoujie that fetches earth in the reaction frame that the adopts static sounding pipe that fetches earth that will assemble; So repeat in the adjunction segmentum intercalaris pipe that fetches earth, press to designated depth until soil sampler;
The 3rd step: bleed, close the two ends valving, the gas in the air bag is drawn out of, and the pipe sidewall opening on the soil sampler sidewall is in opening, leaves standstill 15 ~ 30min and makes the soil sample of the corresponding degree of depth get into soil sampler;
The 4th step: after sampling was accomplished, inflation was closed the two ends valve and is made soil sampler be in closure state after the inflated once more, utilizes reaction frame that soil sampler is proposed from soil.
The 5th step:, confirm the actual grade of institute's soil sampling according to the scale of every joint soil sampler.
Advantage of the present invention: a kind of tubulose air bag envelope opens the side opening soil sampler; Make full use of the flowability of cement mixing pile weak soil; Adopt the side to advance the mode of soil; Can once get all soil samples of every interval 10 ~ 20cm in the target depth range and confirm the degree of depth of institute's soil sampling exactly, overcome the shortcoming of the thin soft layer of not high, the easy omission of sampling rate when soil is advanced in the soil sampler lower end.Soil basketing method processing ease of the present invention only needs control to get airbag apparatus and can realize that envelope opens sidewall opening, and it is efficient and convenient to fetch earth.Therefore soil basketing method of the present invention can be used as and utilizes tubulose air bag envelope to open side opening soil sampler fast detecting cement mixing pile different depth cement factor and the special-purpose soil basketing method of judging clay distribution.
