南通建设机械厂，18252825588，章建，有机械加工车间、组装焊接车间，技术力量雄厚、设备齐全，研制生产出最先进的冲击式岩石基础工程钻机。该钻机技术成熟、噪音小、效率高、投资成本低、使用寿命长等优点。主要用于水利工程、建筑基础、铁路公路桥梁桩基建设、地质勘探及深水井钻孔，该钻机对泥沙层、粘土层、卵石层、岩层都有很好的钻进效果。在我国重大项目建设中起了很大作用，如三峡水电站防水坝，葛洲坝工程、江阴长江大桥、南京二桥、河南小浪底水利枢纽工程、东海大桥、南京三桥等基础建设，青藏铁路大桥、京沈高速桥、京沪高铁、沪昆高铁等桩基建设。
冲击式钻机是灌注桩基础施工的一种重要钻孔机械，它能适应各种不同地质情况，特别是卵石层和岩层中钻孔，冲击式钻机较之其他型式钻机适应性强。同时，用冲击式钻机造孔，成孔后，孔壁四周形成一层密实的土层，对稳定孔壁，提高桩基承载能力，均有一定作用。 18252825588 章建 目前常用的冲击钻机有CK系列，所有配套件安装使用简单，包括卷扬机、桩架、冲击锤、导管、料斗、泥浆泵、胶管、电缆、钢丝绳等。冲击钻机是通过冲击锤头自由下落的冲击作用，将土沙、卵石或岩石破碎，钻渣随泥浆泵或捞渣筒排出。
管式冲击锤有各种大小，根据成孔孔径决定冲击钻锤头的大小重量，此冲击钻锤头在土沙、河卵和硬度低于1000KP的岩石层施工钻进速度较快。
实心冲击钻锤头有各种形状，但他们的冲刃大多是十字和一字型的，有各种大小，根据成孔孔径决定冲击锤的大小重量，此冲击钻锤头在硬度高于1000KP的岩层施工钻进不易损坏。
冲击钻机的钻进是将岩石破碎成粉粒状钻渣，钻进技术简单，但其他所不能施工的地层此钻机可以，这是无法取代的，可以说此钻机没有钻不了的地层（软硬通吃），是随地层的软硬来决定钻进速度的。南通建设机械厂，18252825588，章建 专业生产南通打桩机冲孔桩机 卷扬机，冲击钻，锤头，手拉冲击钻，锤击打桩机，各种手控·自动卷扬机，手拉锤桩机，桥梁打桩机，桩架以及桩机配件，技术力量雄厚、设备精良，工艺完善，符合取得国家级工业产品生产许可证。18252825588 章建
Nantong construction machinery factory, 18252825588, chapter construction, machinery processing workshop, assembly welding workshop, strong technical force, well-equipped, development and production of the most advanced percussive rock foundation engineering drilling rig. The drilling technology is mature, low noise, high efficiency, low investment cost, the advantages of long life. Mainly used in hydraulic engineering, building foundation, railway highway bridge pile foundation construction, geological exploration and deep well drilling, the drilling rig mud sand, clay, gravel layer, strata are well drilling effect. In China the construction of major projects plays a big role, such as the Three Gorges Hydropower Station Dam of Gezhouba Dam project, waterproof, Jiangyin Yangtze River bridge, Nanjing bridge, Henan Xiaolangdi Dam water control project, the East China Sea Bridge, Nanjing bridge and other infrastructure construction, railway bridge, the Beijing-Shenyang high-speed Beijing-Shanghai high-speed rail bridge, Shanghai Kun, Gao Tie pile construction.
Impact drill perfusion pile foundation construction is an important mechanical drilling, it can adapt to the different geological conditions, especially the gravel layer and rock drill, impact drill rig than other types of adaptability. At the same time, with the percussion drill hole, hole, around a hole wall to form a layer of dense soil, on the stability of hole wall, improve pile bearing capacity, have a certain role. 18252825588 Zhang Jian current impact drilling machine CK series, all supporting a simple to install and use, comprises a windlass, pile frame, hammer, catheter, hopper, mud pump, hose, cable, wire rope. Impact drill through the impact hammer free-falling impact, the soil sand, pebbles or broken rock, drilling waste slag or slag with mud pump cylinder exhaust.
Tube type hammer has a variety of sizes, according to the hole diameter of percussion drill hammer decided the size and the weight of the hammer, impact drill in gravel soil, river eggs and is lower than the hardness of 1000KP layer of rock drilling speed.
Solid impact drill hammer in a variety of shapes, but their edge punching mostly cross and a font, a variety of sizes, according to the aperture size and weight determination of impact hammer, the impact drill hammer in hardness is higher than that of 1000KP rock drilling is not easy to damage.
