Problems solved by technology

[0006] At present, river dredging often adopts silt solidification treatment to form solidified dredged soil. Experiments need to be carried out before the solidified dredged soil is treated and reused after solidified dredged soil treatment. However, the traditional experimental methods are complicated, the experimental equipment is complicated, and the experiment is inconvenient and efficient. Low

Abstract

The invention discloses a river channel solidified dredged soil recycling experiment method. The river channel solidified dredged soil recycling experiment method comprises the following steps of: step 1, sampling, uniformly sampling the dredged soil in a grid manner; step 2, performing water content detection on the dredged soil; step 3, detecting harmful substances in the dredged soil; step 4, detecting particle sizes of the dredged soil; step 5, detecting the compressive strength of the dredged soil; and step 6, detecting the shear strength of the dredged soil; wherein the water content detection in step 2 adopts a drying quality measurement method to detect the water content of the dredged soil. The river channel solidified dredged soil recycling experiment method provided by the invention covers water content detection, harmful substance detection, particle size detection, compressive strength detection and shear strength detection, which greatly improves the detection efficiencyand detection effect of the river channel solidified dredged soil recycling experiment, and ensures the safety of recycling the river channel solidified dredged soil; and the invention ingeniously designs a river channel solidified dredged soil recycling experiment device, which has simple structure, convenient operation and high detection efficiency.

Description

technical field [0001] The invention belongs to the technical field of river channel solidified dredged soil treatment, and specifically relates to an experimental method and an experimental device for reuse of river channel solidified dredged soil. Background technique [0002] Dredging is to dredge, widen or deepen waters such as rivers and lakes, and use manpower or machinery to carry out underwater earthwork excavation projects. [0003] Dredging in a broad sense includes reef blasting and beach blasting by underwater blasting. Small rivers artificially interrupted for flow construction. Various types of dredgers are widely used in mechanical construction, and sometimes land construction machinery such as cable shovels are also used. Mechanical dredging began in 1600, and the prototype of the chain bucket dredger appeared in the construction of the port of Rotterdam in the Netherlands. [0004] China began construction with dredgers on the Huangpu River in 1889. In 1...
