Problems solved by technology

At present, there are mainly three types of equipment and methods for survey and sampling in soft soil areas: 1) Soft soil areas have low moisture content and high bearing capacity, and conventional drilling equipment is used for survey and sampling. Soil layers are disturbed to some extent, therefore, high grade undisturbed soil samples cannot be obtained
2) The soft soil area has high water content and low bearing capacity. Conventional drilling equipment cannot work on it due to its heavy weight. The submersible drilling method is used for survey and sampling, all manual work, and the safety factor of the work site Low, the effective drilling depth is shallow, and the target soil layer is greatly disturbed. The soil sample obtained by this method can only be used to identify the composition, and the soil sample cannot be used to obtain accurate physical and mechanical indicators.
3) The soft soil area has a high moisture content and a very low bearing capacity, so personnel and equipment cannot work on it, and the reconnaissance and sampling work needs to be waited for 6 months to 2 years after natural drying. , which greatly prolongs the construction period and increases the cost of the project

Embodiment Construction

[0040] In order to further understand the invention content, characteristics and effects of the present invention, the following examples are given, and detailed descriptions are as follows in conjunction with the accompanying drawings:

[0041] See Figure 1 to Figure 8 , a device for on-site sampling of soft soil areas for survey work, comprising a bearing platform, a sampling power system, a sampling device, a hole-forming device, a hole-protecting device, a generator and a transport device.

[0042] The load-bearing platform includes a chassis 1-1, pedals 1-2 and counter pressure weights (not shown in the figure). The chassis 1-1 adopts a lattice structure formed by longitudinal welded pipes and transverse welded pipes. between the snap connection,

[0043] Pedals 1-2 are laid on both sides of the chassis 1-1 to form a working platform, and anti-pressure weights are placed on the pedals 1-2 and / or the chassis 1-1. The length of the longitudinal welded pipe and the length...

Abstract

The invention discloses equipment for reconnoitering and field sampling in a soft soil region. The equipment comprises a bearing platform, a sampling power system, a sampling device, a hole-forming device, a hole-protecting device, a power generator and a transport device, wherein the transport device is used for transporting the bearing platform to a work place; the hole-forming device is used for forming a sampling hole in the bearing platform; the hole-protecting device is arranged in the hole formed by the hole-forming device; the sampling device is used for obtaining a soil sample in a position with the distance of 15-80 cm from the lower part of the bottom elevation of the sampling hole. The invention further discloses a method for sampling by the equipment for reconnoitering and field sampling in the soft soil region. According to the equipment and the method, the reconnoitering and sampling operations can be carried out in the soft soil region with very high water content and very low bearing capacity, and the high-grade undisturbed soil sample can be obtained.

Description

technical field [0001] The invention relates to a survey and sampling equipment and method, in particular to a survey and sampling equipment and method for on-site sampling in soft soil areas. Background technique [0002] Soft soil area survey is an important work in soft foundation reinforcement engineering and dredging and filling soil improvement engineering. On the premise of ensuring that the engineering design scheme is accurate and feasible, it is a very beneficial job to make the engineering construction proceed scientifically and in a planned way, so as to guarantee the construction period, ensure the quality, and complete the engineering project safely and smoothly. economic and social benefits. [0003] In the early stage of project approval and engineering feasibility study of engineering projects in soft soil areas, it is necessary to have a detailed understanding of the basic soil layer conditions on the site. Therefore, survey and sampling work is required. ...
