Description

Technical Field

[0001] The utility model belongs to the technical field of construction equipment, and specifically relates to an integrated membrane laying device for large single volume density testing using a watering method, which has the advantages of simple structure, high laying efficiency, strong adaptability, convenient transportation and recycling, and economy and environmental protection. Background Art

[0002] In the construction of tailings dams, embankment filling, airport construction and other projects, broken stones, sand and gravel are often used as filling materials. However, due to the large particle size, unevenness, porosity angle and other reasons of the aforementioned filling materials, the conventional ring knife method, sand filling method, nuclear ray method and other methods are not applicable to the in-situ large single density test. The water filling method has the advantages of simple principle, ease of use and accurate results, especially for filling materials such as coarse-grained soil. Therefore, it is currently the appropriate and more commonly used method for in-situ large single density test in geotechnical investigation.

[0003] When conducting a large single density test using the water-filling method, it is necessary to lay the film on the excavated test pit. At this time, generally multiple people will flatten the spare film, then lay it on the test pit, and then find stones or soil blocks to fix the edge of the film. After the test, the stones or soil blocks need to be removed and the film needs to be gathered. Traditionally, the test pit of the water-filling method uses manual laying and gathering of the film, which requires multiple test personnel to cooperate in flattening. Not only is the laying and gathering process of the film cumbersome, which makes the test efficiency low, but the manual laying and gathering of multiple people can easily cause film damage. At the same time, there are construction safety hazards, which affect the progress of the test. After the test, the gathered film has no suitable protective device, which causes the storage of the film to be generally very random. Improper storage or long storage time can also easily cause film damage. If the film is damaged and leaking during the next test, if it is not detected, the film will be replaced and the test will be repeated, which will affect the test efficiency and increase the test cost.
