Description

Technical Field

[0002] Backfill and tamping construction around the road-attached well chamber is a key link in road construction. Before construction, it is necessary to clean up the debris and loose soil around the well chamber, and select suitable backfill materials, such as lime soil, medium-coarse sand, etc., to ensure that their quality meets the requirements. During construction, according to the principle of layered backfill, the thickness of each layer is controlled within a certain range, generally not exceeding 30 cm. Small compacting machines such as frog-type rammers and impact rammers are used for compaction operations. Manual work is carried out in conjunction with light compaction equipment near the well chamber to prevent damage to the well chamber. During the process, the compaction degree is strictly controlled, and each layer is inspected in time to ensure that the compaction degree meets the standard. Attention should also be paid to the protection of the well chamber cover, well seat, etc. to avoid collision, ultimately ensuring the stability of the overall structure and quality safety of the road.

[0003] When carrying out backfill and tamping around the road-attached well chamber, multiple machines are needed to be used together to perform excavation, shoveling, compaction and humidification functions. Construction tools such as excavators, flat plate compactors and sprinkler trucks are used. The construction is relatively complicated and the construction efficiency is low.

The second embodiment is only a preferred embodiment of the first embodiment, and the implementation of the second embodiment will not affect the independent implementation of the first embodiment.

[0055] Specifically, the second embodiment of the present application provides a multifunctional excavator and rammer that integrates digging, shoveling, tamping and humidification.
