Embodiment 1

[0023] see Figure 1-3 , in the embodiment of the present invention, a kind of mud sampler with depth measurement and positioning function, comprises sampling drill pipe 1 and measuring platform 4, and measuring platform extension board 13 is installed around the bottom of measuring platform 4, utilizes measuring platform extension board 13 The contact area between the bottom of the measurement platform 4 and the silt can be increased to keep the device stable. At the same time, it is easier for the user to judge whether the bottom of the measurement platform 4 is in contact with the silt, which is convenient for sampling operations. The top of the measurement platform 4 runs through There is a sampling drill pipe 1, and the sampling drill pipe 1 is threadedly connected with the measurement platform 4. An electromagnetic locker 6 is installed inside the measurement platform 4. The electromagnetic locker 6 can be used to lock the sampling drill pipe 1, so that the sampling drill...

Embodiment 2

[0027] On the basis of Embodiment 1, a drill pipe depth limiting plate 14 is installed in the middle of the sampling drill pipe 1, and the drill pipe depth limiting plate 14 is detachably connected to the sampling drill pipe 1, and the drill pipe depth limiting plate 14 is passed through a locking bolt. Connected with the sampling drill pipe 1, before installation, estimate the drilling depth of the drill bit, adjust the distance between the drill pipe depth limiting plate 14 and the top of the measuring platform 4 according to the drilling depth, and the top of the measuring platform 4 is equipped with a contact switch 7 , the interior of the data signal acquisition transmitter 10 is integrated with an audible and visual alarm, and the audible and visual alarm is electrically connected with the contact switch 7. During the sampling process, the drill pipe depth limiting plate 14 descends with the drill bit. When the drill pipe depth limits When the plate 14 is in contact with ...

Embodiment 3

[0030] A dredging method, comprising the following steps: (1) using the above-mentioned silt sampler with the functions of depth measurement and positioning to accurately locate and sample silt; (2) detecting and analyzing the silt samples to determine the range of silt, Pollution depth and pollution degree; (3) Divide the coordinate range of the silt pollution layer according to the positioning results; (4) According to the coordinate range of the silt pollution layer, use the dredging ship to carry out the dredging operation.

[0031] Using the present invention to accurately locate and sample the sludge, the distribution range of the sludge can be accurately measured, and the sludge samples can be detected and analyzed. Based on the theory of heavy metal enrichment, the ecological hazard coefficient and index of heavy metals in the sludge can be evaluated for heavy metal risks. Determine the silt range and pollution degree according to the evaluation results, and determine t...

Abstract

The invention relates to the technical field of environmental protection and specifically relates to a silt sampler with a depth measurement and positioning function and a desilting method. The silt sampler comprises a sampling drill pipe and a measurement platform. The sampling drill pipe runs through the top portion of the measurement platform; the sampling drill pipe is in threaded connection with the measurement platform; the lower end of the sampling drill pipe is provided with a drill bit; the sampling drill pipe is hollow inside; the inner cavity of the sampling drill pipe forms a sampling tube; the lower end of the sampling drill pipe is provided with the drill bit; the bottom portion of the drill bit is equipped with an electromagnetic gate plate; a multi-stage connecting rod is arranged on the sampling drill pipe; and the top portion of the multi-stage connecting rod is equipped with a data signal acquisition and transmitting device. Through arrangement of the sampling tube,the electromagnetic gate plate, the data signal acquisition and transmitting device, a contact switch, a drill pipe depth limit plate and a GPS locator, the silt sampler can conveniently collect siltsamples, precisely locate collection points, and precisely measure the pH value and temperature of the silt; the measurement data is estimated through assessment software; the GPS is used to preciselylocate the sampling location.

Description

technical field [0001] The invention relates to the technical field of environmental protection, more specifically, a mud sampler with depth measurement and positioning functions and a dredging method. Background technique [0002] Unconsolidated soft fine-grained or very fine-grained soil deposited in still water or slow flowing water environment, formed by physical, chemical and biochemical actions. It is a modern recent sediment. The silt can be silty or clayey according to the particle size composition, and there is very little fine sandy or very fine sandy. The clay minerals of coastal silt are mainly illite and montmorillonite, while freshwater silt is mainly composed of illite and kaolinite. However, silt often contains heavy metal elements. If the silt with heavy metals exceeding the standard is taken without sampling and analysis, the silt will accumulate on the shore, which will often lead to secondary pollution. [0003] Water body sediment pollution has become...
