The brand of Rapid Impact Compaction is Hangshen, and the manufacturer is Tai'an Hengda machinery. It is located in Tai'an City, Shandong Province. It was founded in 2008. The price of the commonly used hc36 hydraulic tamping machine is generally about 130000 ~ 150000 yuan. There is no middleman to make a price difference, the price is cheap, and the cost performance is high. The Rapid Impact Compaction can be used for various landforms and various working methods, especially suitable for the compaction of highway foundation backfill. The Rapid Impact Compaction is applicable to the ribbed and immediate compaction of qualified foundation in the process of highway construction, so as to reduce the post construction foundation settlement of the foundation. The key application positions are the backfill at the back of slab culvert, the junction of filling and excavation, high fill foundation, the junction and widening of new and old foundation, chicken claw irrigation channel, stamping blind spot, inconvenient or unsuitable for the application of dynamic compaction foundation, etc, And other positions that must be ribbed or compacted immediately.

The model of Hangshen brand Rapid Impact Compaction is HC series. The impact energy is divided into 4~150kj, the weight of the hammer is 0.5`10t, and the working frequency is 30-80 times per minute. It has mastered a number of core patented technologies. It has updated the Rapid Impact Compaction to the sixth generation, with higher efficiency, longer service life, and no heating after long-time work. Refer to the following figure for specific model parameters:

Among the numerous models of tamp God brand, hc36 and hc42 are widely used in highway and railway treatment. These two models can meet the needs of subgrade treatment, and the price is relatively appropriate. Hc84 and hc150 hydraulic compactors in the table are mostly used in subgrade and foundation treatment for special needs such as airports. The maximum effective depth can reach 10m, and the effect is remarkable.

High speed hydraulic rammer, in which high speed means to quickly arrive at the compaction site and carry out high-speed and effective compaction, so how can the hydraulic rammer work quickly? Hydraulic compactors must be equipped with loaders and excavators for loading, walking and driving. High speed hydraulic compactors have the characteristics of convenient conversion, high compaction efficiency and strong influence depth. In some special cases and requirements, they can replace the dynamic compaction machine for compaction.

At present, the tamping machines on the market are mainly small electric, diesel and gasoline. These small rammers can only increase the impact on the soil, and the vibration wave transmission is lack of continuity. In addition, due to the lack of sufficient kinetic energy and contact area with soil, the compaction effect is poor and the impact is deep. In addition, diesel gasoline tamper still has the defects of high noise, high energy consumption and low overall efficiency. Therefore, in many formal large-scale projects, this small rammer is no longer used, but hydraulic vibratory rammer and hydraulic rammer.

The key of Rapid Impact Compaction is composed of compaction frame, compaction hammer, compaction plate, buffer device, hydraulic system, electronic control system, etc. among domestic hydraulic compactor manufacturers, independent research and development, production mode and key technology have independent invention patents, and foreign imported methods are no longer used to make up for the domestic hydraulic compactor market.
