Practical and simple compaction degree measurement box for construction site

Abstract

A practical and simple compaction degree measurement box for the construction site comprises a traveling case, an upper instrument formwork, a lower instrument formwork and test instrument devices used for measuring the compaction degree and the water content, wherein the upper instrument formwork, the lower instrument formwork and the test instrument devices are arranged in the traveling case. Die sinking is conducted according to the outer contours of all the test instrument devices used for measuring the compaction degree and the water content to form the upper instrument formwork and the lower instrument formwork. Each test instrument device corresponds to a special pit in the upper instrument formwork and a special pit in the lower instrument formwork. The upper instrument formwork is arranged in an opening cover on the upper portion of the traveling case. The lower instrument formwork is placed in a case body on the lower portion of the traveling case. The upper instrument formwork and the lower instrument formwork are connected in a butt joint mode so that all the test instrument devices used for measuring the compaction degree and the water content can be fixed from the top face and the bottom face. All the instruments required by compaction degree measurement achieved according to a cutting ring method can be placed together, the test instruments are prevented from loss and omission, tests can be conducted on site, data can be provided in time, test data providing time can be saved, and compaction degree measurement can be conducted at any time and in any place.

Description

Technical field [0001] The invention relates to a simple measuring device for the moisture content and compaction degree of fine-grained soil used in the field of infrastructure such as highways and municipal roads, in particular to a practical simple compaction degree measuring box on site. Background technique [0002] In the field of infrastructure such as highways and municipal roads, with the rapid economic development in recent years and the increase in overloaded vehicles, the requirements for highway grade and quality are getting higher and higher, and the road reconstruction cycle is gradually accelerating. The requirements of highway construction project management level, quality monitoring system, and supervision methods have also put forward higher requirements. The quality of highway subgrade compaction is mainly evaluated by specific testing methods and testing data. Failure to meet the standards is caused by the road surface. The main reasons for damage, poor u...

AI Technical Summary

Problems solved by technology

[0004] 1. The personnel on the construction site carry out roadbed compaction, and cannot obtain the water content data of the roadbed in time, and cannot construct in time;

[0005] 2. After receiving the on-site sampling, rush to the construction site, and return to the laboratory for testing after sampling, which takes a long time;

[0006] 3. On-site construction personnel and test personnel cannot jointly analyze and study

[0007] 4. The test samples cannot be measured in time, which affects the accuracy of the test data;

[0008] 5. The test data cannot be provided in time, which will affect the construction progress and lead to the extension of the construction period;

[0011] 1. There is a certain distance between the laboratory and the construction site, and the test cannot be carried out in time;

[0012] 2. There are many and miscellaneous test instruments, which are not easy to carry and easy to miss;

[0013] 3. There is a time difference between the test data and the construction site, which affects the smooth progress of the construction
