Description

Technical Field

[0001] The invention belongs to the field of drilling well wall production, and in particular relates to a drilling well wall integrated test piece production device and method. Background Art

[0002] The western region has very high requirements for the performance of concrete for drilling well walls, which makes it particularly important to make a drilling well wall model during relevant tests. The concrete drilling well wall model uses the similarity theory to reduce the various dimensional indicators of the drilling well wall to be studied according to a certain proportion, and then add the required concrete with the mix ratio obtained based on the test to make a proportional model, conduct corresponding tests, and find the best mix ratio.

[0003] At present, concrete drilling well wall models are often made in a step-by-step manner. For example, various raw materials of concrete are first mixed in a mixer, and then manually poured into the mold in batches and vibrated to obtain various types of well wall models. In indoor geotechnical tests, this production method not only causes a waste of concrete, but also affects the production efficiency of the well wall model. In addition, since most models are generally made with only one or two vibrating rods, the concrete in the mold cannot be fully vibrated when pouring concrete, which affects the vibration compaction effect and causes the model to fail to correctly reflect the various properties of the concrete drilling well wall. Furthermore, many devices do not take into account the treatment of concrete residues after the specimens are made, which will cause the residues to mix into the next group of concrete and even cause the device to wear, resulting in the subsequent specimens failing to meet the standards required for the test.

[0004] Based on this, there is an urgent need for a device and method for making a concrete drilling well wall model, which can integrate all process flows and effectively improve the quality of the model, thereby making the test results more accurate. Summary of the invention
