Problems solved by technology

During the peak time period of filling, the workload of compaction detection is very large. Traditional detection methods require a lot of manual input and high cost.
Moreover, the traditional subgrade compaction test is divided into several steps: digging holes, filling sand, and testing moisture content. Both digging holes and filling sand need to be done manually, and the on-site moisture content test needs to use the alcohol burning method to perform a dry test, which is costly. The time is very long, the detection cycle is long, the detection speed is slow, and the detection efficiency of compaction degree is very low, which cannot meet the needs of rapid and accurate detection of roadbed compaction degree in the current construction process.
[0004] In the prior art, CN202110631975 discloses a road engineering compaction detection equipment, which includes a drilling assembly and a traveling wheel assembly. Although the drilling stability has been greatly improved, the rapid on-site testing of sand filling and moisture content still remains a problem. Unresolved, the compaction test data cannot be issued on site, and it is still difficult to achieve high sampling accuracy, fast detection speed, high detection efficiency, and high detection accuracy

[0091] The sand filling system 1 includes a sand filling bucket 101 and a knife valve 102 arranged at the bottom of the sand filling bucket 101. The knife valve 102 is controlled to open and close by a first telescopic push rod 103, and the first telescopic push rod 103 is electrically connected to the control system 3. connected. Both sides of the sand filling bucket 101 are respec...

Embodiment 2

[0097] The using method of a kind of subgrade compaction quick detection equipment described in embodiment 1 is as follows:

[0098] Step 1: Random sampling

[0099] Open the touch screen 301 of the control system 3, enter the basic information of the project in the software control system, the basic information includes the project name, mileage, road width, etc., then enter the random sampling interface and click, the computer will automatically give the point stake and distance to be detected. Road width centerline distance and other information.

[0100] Step 2: Dig the Holes

[0101] Find the actual position of the point according to the point determined by random sampling, and perform mechanical digging or manual digging at this point to obtain the test hole 5, and the taken soil sample is sealed and stored in a film bag.

[0102] Step 3: Preparations

[0103] (1) Prepare a 220V, 50Hz external power supply or a 220V, 50Hz generator with a power of not less than 5kW on...

Embodiment 3

[0127] The subgrade compaction degree quick detection equipment described in Example 1 was used to test the subgrade compaction degree of a new high-speed filling section in a province in accordance with the "On-site Test Regulations for Highway Subgrade and Pavement" JTG E60-2008. Three sampling piles were used to calculate the average value. The traditional manual test method is used for synchronous comparison, and the test results are shown in Table 1.

[0128] Table 1

[0129]

[0130] It can be seen from the above that compared with the traditional method, the detection equipment described in this application has the same detection accuracy, but the soil sample moisture content detection efficiency is increased by 3 times, the comprehensive detection efficiency is increased by 5 times, and the field compaction degree detection efficiency is greatly improved. .

Description

technical field [0001] The invention relates to the technical field of road construction and construction detection, in particular to a rapid detection device for roadbed compaction and a method for using the same. Background technique [0002] In large-scale construction projects such as highways, railways, lake filling, sea reclamation, bridge erection, municipal construction, etc., there is a large area of ​​filling construction, and then other structural layers are built on the filling layer. Before the construction of the structural layer building, the fill soil needs to be compacted, and the compaction quality of the fill soil is usually evaluated by the index of the fill soil compaction degree. [0003] Usually, the filling of the construction site needs to be carried out on a sunny day to prevent the water content of the filling from being too large and difficult to be compacted. Therefore, the filling is often completed in a period of time. During the filling period...
