Abstract
The utility model relates to a soil taking device and belongs to the field of geotechnical engineering investigation in civil engineering. The pipe-type soil taking device of weak soil with side opened and closed ports comprises a drill portion and a pipe body portion. The pipe body portion is of a multi-sectional combination-type structure with inner and outer sleeved pipes. A plurality of horizontal partition panels are arranged in inner cavities of the inner sleeved pipes at equal interval. The plurality of horizontal partition panels divide the inner cavities of the inner sleeved pipes into a plurality of cavities with the same volume. Rectangular pipe wall side opened ports are symmetrically arranged in each pipe wall of each cavity. Pipe wall side opened ports of the outer sleeved pipes is arranged on the outer pipe corresponding to the rectangular pipe wall side opened ports on each inner sleeved pipe. The size and shape of the rectangular pipe wall side opened ports are the same as those of the pipe wall side opened ports of the outer sleeved pipes. The pipe-type soil taking device of weak soil with the side opened and closed ports makes full use of liquidity of soil after the soil is stirred by a cement mixing pile. Due to the fact that feeding soil from a side face is adopted, all soil samples can be taken at one time within the target depth range with intervals of 10 to 20 centimeters, and depth of the taken solid samples is confirmed.

The specific embodiment
As shown in drawings,
The utility model provide a kind of can be disposable in target depth range, every interval 10 ~ 20cm gets the weak soil drawing out soil equipment of disturbed sample.The drawing out soil equipment main body is two coaxial cylindrical pipes, is divided into inner and outer tubes.Inner tube can slide up and down within the outer tube, and two is fixed with latch, cannot relatively rotate between the inner and outer tubes.
Outer tube and inner tube side are left rectangle tube wall side opening at a certain distance, and described rectangle tube wall side opening is that split both sides, and the openings of sizes shape is identical.Inner tube arranges horizontal partition panel in 5 ~ 10cm position below each rectangle tube wall side opening, make the soil of getting from rectangle tube wall side opening position be stored in horizontal partition panel top.Described outer tube wall side opening lower end is provided with the outer tube wall reviewing, and the angle of inclination of described outer tube wall reviewing is between 30 ° ~ 45 °.
Drawing out soil equipment is the joint formula, and every joint length is definite value except head saves, and the internode of inner and outer tubes is provided with and is threaded.
Inner tube within the outer tube straight line slides up and down, and when inner tube pipe sidewall opening and outer tube pipe sidewall opening staggered, inner and outer pipe was closed, and cement-soil can not enter in the pipe; When inner tube pipe sidewall opening overlapped with outer tube pipe sidewall opening, inner and outer pipe was opened, and utilized cement mixing method just to stir the flowability of rear soil, and cement-soil enters through the tube wall side opening, and was deposited on the horizontal partition panel in the inner tube.
The concrete steps that the utility model tubular type side switching mouthful drawing out soil equipment fetches earth are:
The first step, head is saved inner tube be in the same place with first joint outer tube sleeve, the tube wall side opening on this moment first joint inner tube and the tube wall side opening on the outer tube stagger, and drawing out soil equipment is closed state;
Second step, head is saved on the reaction frame that inner and outer pipe is fixed on static cone penetration equipment together, shake the static sounding runner, head is saved inner and outer pipe be pressed in the soil;
The 3rd step, installation inner tube middle node, with inner pipe joint the inner tube middle node is connected with first joint inner tube, tighten first joint inner tube and inner tube middle node, with outer tube joint the outer tube middle node is connected with first joint outer tube, tighten first joint outer tube and outer tube middle node, after installing middle node, the tube wall side opening on the inner tube of this joint and the tube wall side opening on the outer tube stagger, and drawing out soil equipment is closed state;
The 4th goes on foot, the inner and outer pipe middle node is fixed on the reaction frame of static cone penetration equipment together, shakes the static sounding runner, and it is pressed down;
The 5th step, repetitive operation third step and the 4th step connect inner tube middle node, outer tube middle node, successively until target depth;
The 6th step, fixing inner tube, with static cone penetration equipment outer tube is pressed down certain distance, tube wall side opening on the inner tube is overlapped with outer tube wall side opening on the outer tube, drawing out soil equipment is opened, soil enters inner tube from the described inner tubal wall side opening that coincides together and outer tube outer tube wall side opening, fall on the horizontal partition panel of each chamber on inner pipe, gas in each chamber is overflowed from the steam vent of each chamber lower end, overflow from the slit between the inner and outer pipes again, after 10 ~ 20 minutes, fixing inner tube, promote again outer tube, during lifting, the outer tube reviewing cuts the soil of its top into inner tube, the outer tube range of lift is identical with depression distance, tube wall side opening on the drawing out soil equipment inner tube and the tube wall side opening on the outer tube stagger again at this moment, in fixing with latch at last, outer tube makes it that relative sliding no longer occur, promote simultaneously inner and outer tubes, corresponding every joint inner tube middle node and every joint outer tube middle node are backed out together successively, take out the soil on the horizontal partition panel of each joint inner tube middle node, the markd aluminium box of packing into is determined the actual grade that fetches earth according to every joint length of cutting off distance and drawing out soil equipment.
The utility model take full advantage of cement mixing method just stirred rear soil flowability, 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 determine exactly the degree of depth of soil sample, overcome the shortcoming of the thinner soft layer soil of not high, the easy omission of sampling rate when advancing soil from the lower end.And equipment is simple, processing ease, and it is efficient and convenient to fetch earth, and can be used as the special-purpose drawing out soil equipment of measuring the cement mixing method cement factor and judging weak interlayer.
