Characteristics of drilling tools: Cone and straight tubes are selected according to the working conditions as appropriate; The selection of straight guide plate or no guide plate depends on the working conditions; Scope of application: Cleaning sediment at the bottom of the hole, flow plastic soft soil strata;
Characteristics of drilling tools: Large soil inlet design, open cylinder structure, efficient slag discharge, and improved drilling efficiency; The cylinder, guide plate, and reinforced ribs are designed to enhance the service life of the drilling bucket; Arrange guide bars around the cylinder to prevent drilling suction; Applicable strata: clay layer, silt layer, strongly weathered rock layer;
Characteristics of drilling tools: Center cone guidance, cone drilling, rock fragmentation; The double headed spiral is subjected to uniform force and should not deviate from the hole; Double helix has strong slag carrying capacity, viscous formation, and single helix is easy to unload slag; Applicable strata: pebble layer, mudstone, sandstone layer, strongly and moderately weathered hard rock layer;
Characteristics of drilling tools: Straight spiral design, convenient for carrying slag; The double headed spiral is subjected to uniform force and should not deviate from the hole; Double helix has strong slag carrying capacity, viscous formation, and single helix is easy to unload slag; Applicable strata: clay layer, strongly weathered layer, gravel layer;
Characteristics of drilling tools: The cylinder ring is cut to release the rock confining pressure, and the trident follows suit to break; Strata with rich fissure development, trident enhances slag carrying capacity; Applicable strata: gravel soil layer, strongly weathered rock layer, moderately weathered rock layer;
Characteristics of drilling tools: Cylinder ring cutting releases rock confining pressure; Cutting tooth step crushing and grinding drilling; Small drilling tools have a high core extraction rate, while large drilling tools are graded and broken together; Applicable strata: backfill layer, moderately weathered rock layer, bedrock layer;
Characteristics of drilling tools: The small cylinder is cut in first, and the large cylinder drill follows the ring cutting to release the rock confining pressure; Cutting tooth step crushing and grinding drilling; Small drilling tools have a high core extraction rate, while large drilling tools are graded and broken together; Applicable strata: gravel soil, pebble layer, moderately weathered rock layer;
Characteristics of drilling tools: Cylinder ring cutting releases rock confining pressure; Roller drill teeth are used for rolling and grinding drilling, resulting in minimal wear and tear on the drill teeth; Small drilling tools have a high core extraction rate, while large drilling tools are graded and broken together; Applicable strata: medium and light wind layers, hard rock layers, and ultra hard foundation rock layers;
Characteristics of drilling tools: Optional elongated straight cylinder design to prevent slanted holes during drilling; Built in anti suction drilling water hole, add skirt edge according to working conditions; Applicable strata: silt layer, gravel layer, silt (clay) layer, strongly weathered rock layer, etc;
