Description

Technical Field

[0001] The utility model relates to the technical field of geotechnical engineering construction, in particular to an anti-fly slag and noise reduction device for the air holes of a rammer. Background Technique

[0002] A rammer is a heavy impact tool used in geotechnical engineering such as soil, roadbed, and foundation. Its working principle is to use the acceleration of gravity to transfer the energy of the head to the soil or other working materials, so that they are closely arranged and the density is increased. This compaction process helps to improve the bearing capacity, stability, and drainage performance of the soil. In construction engineering, the dynamic compaction technique is widely used because of its significant reinforcement effect, wide range of applicable soil layers, simple construction machinery, and material saving.

[0003] At present, during the construction of traditional dynamic compaction projects, when the rammer collides with the ground, the fly slag is randomly thrown into the sky through the air holes, making a huge noise and raising dust. At the same time, the fly slag is easy to hurt people when it lands, which has a great impact on the lives of construction workers and surrounding residents. It can only be used far away from residential areas, and the use area is limited, becoming a drawback in dynamic compaction project construction.

[0004] Therefore, we provide an anti-fly slag and noise reduction device for the air holes of a rammer to solve the above problems. Content of the Utility Model

[0026] Furthermore, the connecting component 31 includes an internal thread 311 of the air hole and an external thread 312 of the blocker. The internal thread 311 of the air hole is arranged inside the air hole 2, and the external thread 312 of the blocker is arranged on one side of the internal thread 311 of the air hole. Through the setting of the connecting component 31, the stable connection between the rammer 1 and the silencing mechanism 3 is ensured, so that the whole device can work effectively and run reliably for a long time.

[0027] Furthermore, the blocking component 32 includes a flying slag blocker 321, a blocking net 322 of the blocker and an internal thread 323 of the blocker. The flying slag blocker 321 is installed at the top end of the external thread 312 of the blocker, the blocking net 322 of the blocker is fixedly connected to the inside of the flying slag blocker 321, and the internal thread 323 of the blocker is arranged at the top end of the blocking net 322 of the blocker. Through the setting of the blocking component 32, the flying slag generated when the rammer 1 works is blocked to prevent it from spraying out of the air hole 2, effectively protecting the surrounding environment and the safety of workers, and improving work efficiency.

[0028] Further, the sound insulation component 33 includes an outer muffler thread 331, a muffler 332, sound insulation elements 333, and an inner muffler thread 334.

A plurality of sound insulation elements 333 are installed inside the muffler 332. The inner muffler thread 334 is installed at the top of the muffler 332. Through the setting of the sound insulation component 33, the noise generated during the operation of the rammer 1 is reduced, the noise level of the working environment is lowered, the comfort of the work site is improved, and at the same time, it helps to protect the hearing health of the workers.

In the third step, during construction, the blocker net 322 inside the slag blocker 321 blocks the slag and dust flying upward through the air hole 2. In the fourth step, when the dynamic compaction noise enters the muffler 332, the noise is reflected and attenuated multiple times after passing through the layers of sound insulation elements 333, and the decibel is reduced, thereby achieving the purpose of sound insulation. In the fifth step, when the sound insulation effect of one muffler 332 is not good enough, the outer muffler thread 331 at the lower part of the muffler 332 and the inner muffler thread 334 at the upper part can be used to install another muffler 332 on the upper part until the sound insulation effect meets the requirements. In this way, the use process of a device for preventing slag flying and sound insulation on the air hole of a rammer is completed.
