Embodiment

[0034] Example: such as Figure 1-5 As shown, an underwater concrete sampler and sampling method include a sampling system and a manipulation rope 6; the sampling system includes a sampling outer cylinder 1, a sampling inner cylinder 2 and a base 3; the base 3 is detachably connected to the outer cylinder 1 Bottom; at least one sampling port 11 is opened on the outer wall of the sampling outer cylinder 1, the sampling inner cylinder 2 is set in the outer cylinder 1, and the control rope 6 drives the sampling inner cylinder 2 to move up and down along the inner wall of the sampling outer cylinder 1, The sampling port 11 is opened or closed; the sampling outer cylinder 1 is cylindrical, and the upper opening is closed. The center of the top surface of the sampling outer cylinder 1 is provided with a connecting hole, and the sampling outer cylinder 1 is welded with a hollow hole corresponding to the connecting hole. Shaped connecting pipe 4, the outside of the connecting pipe 4 i...

Abstract

The invention relates to an underwater concrete sampler and a sampling method. The underwater concrete sampler comprises a sampling system and a manipulation rope; the sampling system comprises a sampling outer barrel, a sampling inner barrel, and a base; the base is detachably connected to the outer barrel bottom; at least one sampling port is formed on an outer wall of the sampling outer barrel,the sampling inner barrel is sleeved in the outer barrel; the manipulation rope drives the sampling inner tube to move up and down along an inner wall of the sampling outer barrel so as to open or close the sampling port; the sampler can precisely position the sampling location without cooperating with other tool according to attached scale indication; the sampling operation is simple and fast.

Description

technical field [0001] The invention belongs to the technical field of construction engineering foundation construction, and in particular relates to an underwater concrete sampler and a sampling method. Background technique [0002] Bored piles have the advantages of fast construction speed, large bearing capacity, and strong applicability. They are a form of foundation structure widely used in the field of construction engineering. The method of mud retaining wall and underwater concrete pouring is adopted. [0003] During the pouring process of the pile foundation, the top surface of the underwater concrete in the pile hole is inevitably covered by sediment, garbage concrete and other sundries. Conventional tools such as bamboo poles are difficult to correctly identify whether the underwater concrete at the designed (specified) position meets the requirements, and corresponding targeted measures cannot be taken, thereby affecting the quality of the pile foundation or inc...
