Scope of application and characteristics of vibrotamping

In any kind of construction work, including the construction of private houses and landscaping, you need a special tool - vibrating rammers for soil compaction. Compact in size motorized apparatus, controlled by man, due to the powerful oscillatory movements in the vertical direction makes the soil particles evenly distributed over the voids. The depth of the seal depends on the characteristics of the particular model.

Scope and design of the tool

Because of the characteristic appearance and “jumping” movements performed during the work, the vibro-rammer is also called "Vibronopod". The tool is used in various types of work:

• laying footpaths;
• the formation of a neat house territory;
• soil compaction in front of the flooring in the construction of single-storey houses and structures;
• when laying pipes, cables and construction of communication wells for sealing backfill;
• the formation of ground pads for the foundations of buildings, tamping pits;
• soil compaction around piles;
• patching roads;
• strengthening of the soil of embankments and ditches.

Arranged device as follows: in the upper hull with a handle for control is the engine. The movement of the motor is transmitted through a crank mechanism to a reciprocating moving piston - this is an internal element of the vibration damper (tamper “leg”). A shock platform is attached to the vibration damper moving up and down, which acts on the ground, causing it to condense.

Types of vibrotampers

It is accepted to subdivide vibrotampers into two large species groups, depending on the intended purpose.

1. For work with loose soil. This is a tool with a small frequency and high amplitude of movement.
2. For handling viscous and mixed substancesAsphalt tampering designed vibroleg with a small amplitude and a high frequency of vibration.

Also, depending on how the motor is equipped with the unit, the following classification of the instrument is generally accepted:

• electric;
• petrol;
• diesel.

Electric vibrotamper - the most affordable tool. It differs from fuel analogs in less noisy work, not poisoning the space with harmful emissions. The advantage of using electrically operated vibro-legs in closed rooms is obvious: the tool is easy to operate and maintain. The main disadvantage is binding to the network power, which significantly affects mobility.

More often, in terms of technical characteristics, electric aggregates for soil tamping are more appropriate for handling bulk materials.

Petrol vibrotamper is the most demanded universal tool, since it is not limited in mobility, robust and productive, it can work in any weather conditions. Petrol fuel is available and its consumption is low. Maintenance is simple, the price is affordable. The main disadvantage is that it is undesirable to use indoors due to exhaust gases.

Diesel vibrotamper It differs from other analogs in high power and, therefore, in performance. Diesel engine models are used in those types of work where a large impact force and the ability to perform a large amount of work are required from the apparatus. Diesel units are worth a lot. The main disadvantage is a large noise level.

It is impossible to say which type of instrument is better. You need to choose the unit according to the main purpose, as well as important technical indicators affecting the performance and price category of the device.

Characteristics determining the effectiveness of the tool

The effectiveness of using vibro-legs with any type of motor depends on several characteristics.

1. Motor power determines the frequency of translational movements and affects performance.
2. Impact area (tamping soles) - the mobility of the device depends on it. The smaller the outsole, the more convenient the tool in the cramped conditions.
3. Vibration frequency - key performance characteristic.The more beats per minute vibrobog makes, the more space can be sealed in a certain time period.
4. Tamping depth (amplitude).
5. Device weight important to target selection. For example, a lightweight and maneuverable design is needed for trenching trenches, a heavier aggregate is important for trenching.
6. Fuel consumption (for models with gasoline or diesel internal combustion engine).
7. The presence of anti-vibration system for the handle (it is not available for all models) to reduce the vibration load on the hands of the operator during operation.

The price of vibrotamper depends on the type of motor and the above characteristics, as well as the popularity of the brand.
