A ground bearing capacity test device for civil engineering

Abstract

The invention relates to a bearing capacity experiment device for a foundation for civil engineering. The problem that in a traditional teaching process of the civil engineering major, the demonstration of detecting the bearing capacity of the foundation cannot be conducted in class is solved; an experiment box body is divided into a plurality of cavity bodies, soil of different types can be placed in the cavity bodies to achieve the purpose that thedetecting experiment for thebearingcapacity of the foundationadopting the soil of different types can be simulated, and when a tapered probe penetrates through soil under the knocking effect of a heavy hammer and reaches the distance required by the experiment, the number of times of knocking is recorded on a recording board; the length, penetrating through soil, of the tapered probe and the number of the required times of knocking are shown visually, the bearing capacity of the foundation of the detected soil is obtained through evaluation, and a teacher combines theoretical knowledge of books with on-site demonstrations in class to help students to master knowledge points of all steps in the process of detecting the bearing capacity of the foundation better, and the teaching efficiency is greatly improved.

Description

technical field [0001] The invention relates to a foundation bearing capacity experiment device, which belongs to the technical field of foundation experiments, and specifically designs a foundation bearing capacity test device for civil engineering. Background technique [0002] The bearing capacity of the foundation is a basic and important topic in the study of soil mechanics. It occupies an important subject position in the teaching of civil engineering. Due to the influence of the bearing capacity of the foundation, especially the influence of the rise and fall of the groundwater level, the phenomenon of tilting or even destruction of buildings often occurs , Another area that is greatly affected by the bearing capacity of the foundation is in the field of roads and bridges.

[0002] The bearing capacity of the foundation is a basic and important topic in the study of soil mechanics. It occupies an important subject position in the teaching of civil engineering. Due to the influence of the bearing capacity of the foundation, especially the influence of the rise and fall of the groundwater level, the phenomenon of tilting or even destruction of buildings often occurs , Another area that is greatly affected by the bearing capacity of the foundation is in the field of roads and bridges. Soft soil foundations are more common in the construction of roads and bridges. This kind of soil has low permeability. When the water content in the soft soil reaches a certain specific gravity, the soil The fluidity of the foundation will increase, which further increases the difficulty of the construction of the soft soil foundation. Therefore, in the process of road and bridge construction, the test requirements for the bearing capacity of the foundation are more stringent. Whether the test of the bearing capacity of the foundation is accurate is directly related to the stability of the road and bridge. and the smooth construction of the entire project; therefore, the teaching course of the foundation bearing capacity experiment is extremely important in the teaching of civil engineering majors, and it is very important for students to better grasp the key points of the foundation bearing capacity test. However, under normal circumstances, At present, the test process of foundation bearing capacity is generally difficult to record in engineering practice, and there is a lack of corresponding practical materials in the teaching of foundation bearing capacity test, which is not conducive to the classroom teaching of foundation bearing capacity test. If students are directly taken to the engineering site to learn and teach It is also unrealistic. If students are only taught according to the theoretical content in civil engineering textbooks, it will not satisfy the intuitiveness of classroom teaching, making the whole classroom teaching process more boring and boring, which is not conducive to students' learning. Therefore, it is necessary to design a An experimental teaching device for foundation bearing capacity used in civil engineering classroom teaching. During the teaching process of foundation bearing capacity test, civil engineering teachers rely on the theoretical content in textbooks, and then demonstrate it to students on the spot through the foundation bearing capacity experimental teaching device. The entire test process enables students to better grasp the knowledge points in the classroom teaching of foundation bearing capacity testing. In view of the above, it is necessary to design a foundation bearing capacity experimental device for civil engineering
