Product Description

Conventional down-the-hole hammer operations generally use a single hammer, mainly for geological prospecting, water wells, anchoring and other hard rock constructions with small diameters. Conventional drilling diameters range from Φ90mm to Φ1200mm. In the process of large-diameter pile hole construction, single down-the-hole hammer is used for operation, and the size of the down-the-hole hammer is relatively large. During use, there are defects such as excessive air pressure, low impact frequency, and high manufacturing cost.

Combine multiple small medium and high pressure DTH hammers to form a clustered DTH hammer with a drilling diameter of Φ600mm～Φ3000mm. In the process of use, each small hammer uses a lower air pressure, all ranging from 1.0 to 1.8 MPa, and the impact frequency is high. Each small hammer can be disassembled separately, without affecting or connecting other small hammers, which is convenient for maintenance, repair and replacement, and greatly reduces the subsequent cost.

In the process of large-diameter pile hole construction, if the single DTH hammer is used for operation, the size of the required DTH hammer is relatively large. During the use of the large single DTH hammer, the air pressure is too high, the impact frequency is low, and the impact frequency is too high. Defects such as high manufacturing cost. Therefore, in actual use, it is usually used to combine a plurality of small down-the-hole hammers to form a cluster type down-the-hole hammer for operation.
