Description
Technical Field
The invention relates to the field of soil sampling equipment, in particular to measuring equipment convenient for soil sampling.
Background
Pile foundations are one of the basic forms widely used in urban construction. The pile sinking action can cause shearing deformation and stress damage of the soil body around the pile, so that the original structure of the soil body is damaged and destroyed to generate soil body remodeling, and the process inevitably leads to rapid reduction of the physical and mechanical properties of the soil body around the pile. The method for accurately predicting the bearing capacity of the pile foundation and evaluating the adverse effect of pile sinking construction on surrounding strata and adjacent structure facilities has important scientific theory and engineering practice values. To achieve this, the characteristics of the pile-soil interface must be truly known, as it determines the development of stresses, strains in the soil surrounding the pile.
In general, when the pile body is displaced in the soil, the stress state of the contact surface of the pile body and the soil body is complex due to the large difference between the material characteristics of the pile body and the material characteristics of the soil body, and soil particles near the contact surface are displaced. And the displacement of the soil particles at the contact surface causes the soil particles to generate dislocation with other soil particles, and finally the displacement field and the stress field in the surrounding soil are changed. The mechanical properties of the materials on the pile-soil interface can be said to have very important influence on load transmission and shear damage development of soil around the pile, and the interface property description and research are helpful for accurately grasping the pile foundation bearing capacity development mechanism and the influence mechanism of pile sinking activities on surrounding stratum from a mesoscopic level, so that the reliable design of the pile foundation bearing capacity is truly realized, and the adverse influence of pile sinking construction on the surrounding environment is reduced.
In the current construction, the collection of the soil with general texture is simple and convenient, and the soil sample of the target point can be obtained only by drilling with the measuring pile, so that the method is widely applied in the current construction and the technology is mature. However, because the soil has various forms, in some soil in which groundwater is permeated, the soil at the bottom often becomes mud-like, and in actual construction, it is very difficult to collect and sample by adopting a general measuring pile, because the moisture in the soil is too much, the pneumatic hydraulic pressure under the soil layer is large, and is very difficult to go deep, and after sampling, because the pneumatic hydraulic pressure, the measuring pile is difficult to retrieve, the general construction operation steps are mechanical excavation or heating columns are selected to go deep, the mechanical excavation mode is adopted, the damage area is large, the later repair is difficult, and a large amount of manpower and material resources are consumed for operation, the energy consumption required by the later is relatively large, the heating time is long, the construction time is short, and otherwise the moisture can permeate.

The measuring pile body 2 is of a hollow structure, and the measuring pile body 2 comprises a broken soil end which is used for extending into a soil layer; the broken soil end is provided with an opening. The end opposite to the broken soil end is a connecting end, and the side surface of the connecting end is provided with a pressure guiding hole 3, so that after the broken soil end enters a soil body, the gas in the measuring pile body 2 can be discharged through the pressure guiding hole 3. The pressure guide hole 3 is not arranged, when soil samples are collected in wet mud, the inside of the measuring pile body 2 is isolated by the wet soil to form an independent airtight space, so that the measuring pile body 2 is not easy to advance during drilling, and the measuring pile body 2 is difficult to extract after sampling. The pressure guide holes 3 are arranged, so that the pressure inside the measuring pile body 2 can be relieved at any time, and the situation is avoided.
In this embodiment, two pressure guiding holes 3 are arranged side by side, and the first half cylinder and the second half cylinder are respectively arranged, so that the exhaust efficiency is improved, and meanwhile, the device is also arranged for adapting to the follow-up soil dividing claw 5.
In this embodiment, the connection end is further provided with a connection frame 1 for connection with the mechanical arm, and the connection frame 1 may be designed and replaced according to an actual connection structure of the mechanical arm.
Be provided with branch soil block 4 in the side of measuring pile body 2, divide soil block 4 to be rectangular shape stereoplasm piece, can use stainless steel to make, and then weld the side of measuring pile body 2, divide soil block 4 can improve the sectional area of measuring pile body 2 when the sample of breaking earth to break out for measuring pile body 2 bigger hole body, reduce the frictional force of soil to measuring pile body 2.
Referring to fig. 1 and 2, a soil dividing claw 5 for breaking the soil is provided at the broken end of the measuring pile body 2, and when soil sampling is performed, the soil sample is put into the measuring pile body 2 while drilling through the soil dividing claw 5.

The connection plate 51 and the measuring pile body 2 form such an inclined relationship, so that the connection plate 51 can also provide an acute angle soil separating claw 5, thereby improving drilling efficiency and reducing energy consumption.
In this embodiment, the included angle between the connecting plates 51 and the central axis of the measuring pile body 2 is 15 °, so that an included angle of 30 ° is formed between the two connecting plates 51, and practice proves that the included angle can ensure that the soil separating fingers 53 on the two connecting plates 51 can effectively discharge separated soil during drilling, thereby improving drilling efficiency.
The inner wall of the measuring pile body 2 is fixedly provided with a plurality of anti-blocking blocks 22, and the surfaces of the anti-blocking blocks 22 are provided with a plurality of protruding points. Soil is inside measuring pile body 2 if too much, can agglomerate and glue and be glutinous, and is very inconvenient when taking out like this, prevents the bump that sets up on the block 22 through inside structure, can form a lot of clearances, after measuring pile body 2 takes out, shakes, can be very easy with inside soil glues and glues the glutinous destruction, can be relaxed carry out soil sampling.
The measuring equipment convenient for soil sampling provided by the invention has the following beneficial effects:
1. the pressure is relieved through the pressure guide hole 3, so that the force is applied to advance when the measuring pile body 2 is drilled, and the measuring pile body 2 is conveniently pulled out after sampling. So that the measuring apparatus facilitating soil sampling can be applied to various types of soil.
2. The measuring pile body 2 is arranged into the first half cylinder and the second half cylinder, so that the manufacturing cost is reduced.
3. Through the setting of dividing the soil block 4, reduced the resistance of measuring pile body 2 when boring, convenient construction's going on.
