Embodiment Construction

[0033] refer to Figure 1-3 , a soil sampling testing equipment for urban environmental protection projects, including a casing 1, a drill pipe 2, a turntable 3, a drill bit 5 and a pressure plate 4.

[0034] Of note above are:

[0035] 1. The lower part of the drill pipe 2 is slidingly connected with the casing 1, and the upper part of the drill pipe 2 is threadedly connected with the casing 1. Therefore, when the turntable 3 is turned, the drill pipe 2 can move a certain distance relative to the casing 1, so as to carry out drilling at different depths. Soil sampling operations.

[0036] 2. On the side wall of the end of the drill pipe 2 away from the turntable 3, there are multiple sets of sampling ports 6 from top to bottom, and the multiple sets of sampling ports 6 are all set at the lower end of the drill pipe 2. When the casing 1 is inserted into the ground for a certain distance, , and then the drill pipe 2 is drilled down to a designated position, and the soil at di...

Abstract

The invention discloses soil sampling and detecting equipment for urban environmental protection engineering. The equipment comprises a sleeve, a drill rod, a turntable, a drill bit and a pressure plate, wherein a plurality of groups of sampling ports are formed in a side wall of one end, far away from the turntable, of the drill rod from top to bottom, and a plurality of annular moving grooves are formed in the drill rod; and each annular moving groove is communicated with lower ends of the corresponding group of sampling ports. The equipment is advantaged in that closing of the multiple sampling openings is easy to control, a problem that part of soil enters the drill rod to affect the sampling accuracy when sampling is not needed can be avoided, multiple sets of adjacent sampling openings can be separated in the sampling process, and therefore a problem that part of soil located on the upper portion falls into the sampling opening on the lower portion can be avoided; and meanwhile, closing of the sampling ports and the separation operation among a plurality of groups of sampling ports can be synchronously carried out only by using the same acting force, so use convenience of the detection equipment is effectively improved.

Description

technical field [0001] The invention relates to the technical field of environmental protection engineering, in particular to a soil sampling and testing device for urban environmental protection engineering. Background technique [0002] Urban environmental protection engineering refers to projects specifically for urban environmental protection. When performing urban environmental protection engineering operations, it is sometimes necessary to sample and detect urban soil. After retrieval, the patent document with the patent number of CN212780032U discloses a soil sampling and testing equipment. , including casing, drill pipe, drill bit and turntable, the outside of the bottom end of the casing is fixedly sleeved with the pressure plate, the drill pipe is movably installed in the casing, the bottom end of the drill pipe is detachably equipped with a drill bit, and the top end of the drill pipe is The turntable is fixed, and the drill pipe is hollow. [0003] There are fol...
