Embodiment

[0027] One, purchase sheet metal, carry out cutting, slotting, welding respectively by the required size of each parts three sides square tube 1) of the present invention, slide film 2), diaphragm slot baffle plate 3), diaphragm 4), wherein :

[0028] Three-sided square tube 1) is a structure welded by three plates surrounding a square column. The angle between the two faces is a right angle. The two plates on both sides have the same shape. The upper part is a rectangular square and the lower part is 1 / 4 discs, the shape of the board in the middle is rectangular, and there are slots for transverse partitions at the same distance on the board, and slots are left on the edges of the three boards for the combination of other structures. There is a size scale to monitor the depth of the sampler inserted into the soil.

[0029] Sliding film 2) is a part that cooperates with the three-sided square cylinder to form a square column cylinder. It is inserted through the slot on the e...

Abstract

The invention provides a press-in slide-vane sampler structure for acquiring a soft soil, sludge or sewage sludge undisturbed sample with high water content in a sludge storage field, dredger fill field and landfill field and an installation and using method. The press-in slide-vane sampler structure can sample according to the conditions of soft flow state soil in the depth direction of sludge storage yards and dredge fill fields, and the acquired mud sample retains in-situ physical and chemical properties in the sampler. The whole structure comprises a three-sided square cylinder, a slide soft vane, a trabecula slot baffle plate and a trabecula. The sampler adopts a modular design, can control the length of sample separation length as well as the size of a sampling region and sampling precision. The sampler is simple, light, simple and convenient in operation, high in efficiency and low in sampling cost.

Description

technical field [0001] The invention relates to a portable in-situ sampler and sampling method for high-moisture fluid soft soil, silt, and sludge undisturbed used in silt storage yards, dredging land reclamation sites, and garbage sludge treatment sites, especially for The utility model relates to a light in-situ test instrument designed for the rare soft fluid state soil conditions in the depth direction of the sludge storage yard, the dredging filling site and the sludge treatment site, and belongs to the related technical fields of geotechnical engineering and environmental engineering. Background technique [0002] In river dredging and dredging projects, land reclamation projects and landfill projects of garbage and sludge, the problem of consolidation of soil with high water content will be encountered. For sites with high water content silt, if the drainage of the site is not smooth or the clay content of the dredged fill soil is high, the consolidation and settlemen...
