Deep layer soil sampling device for building construction

Abstract

The invention discloses a deep layer soil sampling device for building construction. The deep layer soil sampling device comprises a fixing frame and an ascending and descending frame, wherein the fixing frame is provided with a square frame plate and four slide rods arranged under the square frame plate; the ascending and descending frame is positioned under the square frame plate, and is glidingly connected with the four slide rods; a controller is arranged on the upper plane of the square frame plate; an ascending and descending device is arranged between the square frame plate and the ascending and descending frame; a first motor is fixed on the bottom surface of the square frame plate; an output shaft of the first motor is connected with a transverse threaded rod; the ascending and descending device comprises a fixing sleeve, a threaded sleeve and a hinging rod. The structure of the ascending and descending device in the device is ingenious; the stable ascending and descending ofa sampling tube can be ensured, so that the taken soil sample can completely maintain the appearance in the soil; the accurate construction exploration work is greatly facilitated; the opening and closing of a pressurization plate are driven through a hydraulic cylinder, so that the smooth taking of the soil is ensured; the occurrence of sampling difficulty under the conditions of soil scatteringand the like can be avoided.

Description

technical field [0001] The invention relates to construction equipment, in particular to a deep soil sampling device for construction. Background technique [0002] During building construction, in order to ensure the stability of the building, foundation construction is required. The soil layer of the building foundation is divided into rock, gravel soil, sand, silt, cohesive soil and artificial filling. There are two types of foundations: natural foundations and artificial foundations (composite foundations). A natural foundation is a natural layer of soil that does not require reinforcement by humans. The artificial foundation needs to be reinforced by human beings, and common stone chip cushions, sand cushions, mixed lime-soil backfill and then compacted, etc. [0003] In order to ensure the firmness of the foundation, it is necessary to test the soil before construction, and the soil needs to be preliminarily explored, so it needs to be sampled for inspection.

Problems solved by technology

[0003] In order to ensure the firmness of the foundation, it is necessary to test the soil before construction, and the soil needs to be preliminarily explored, so it needs to be sampled for inspection. There are several problems with the existing soil sampler: when sampling, due to the relatively hard ground , the sampling process is often time-consuming and laborious; and the sampling process is often due to gravity, so that part of the obtained samples are lost, and it is impossible to obtain complete samples of each layer of soil
