The local directional drilling is just staring in terrane , the equipments and the technologies ca n ' t satisfy far and far the spot construction needs , according to current circumstance and considing the existed equipments , the author put forward drilling by air hammer in terrane , having designed compounded - drilling tools , and recommended technology parameters . producing experiments have obtained good achievements in economic and in techniques 國內定向鉆進鋪管技術在巖層只是剛剛起步,設備、工藝遠遠不能滿足現場施工需要,本文針對國內、外巖層定向鉆進非開挖設備及工藝現狀,結合國內大多施工單位的已有設備,提出巖層空氣潛孔錘導向鉆進工法,設計了適合巖層鉆進的實用鉆具,并提出具有針對性的工藝參數,生產性試驗取得了良好的經濟技術指標。

In our company we have forging , costing and heat treatment workshops with advanced producing equipments . all the tasks which refused by the other companies will be done well here . there are many large - size air hammers , blast furnaces and costing equipment including all sorts of heats treatment equipment , costing equipment including all sorts of heat treatment equipments 我公司下屬鍛造鑄造熱處理加工廠各一座,有先進的生產設備,可以接收其它部門不愿承攬,甚至不敢承攬的艱巨任務,我們有大型的空氣錘和高爐冶煉鑄造設施和場地,有淬火退火回火各種熱處理設備。

Refer to the damage problem to the motor of c41 - 400 air hammer caused by driving system fault , an acknowledged improvement that is adding a v - belt driving into the system has been promoted with failure situations occasionally because of irrational supporting structures 摘要針對c41 - 400型空氣錘由于傳動系統故障而導致電動機損壞的問題,通常的改進方案是增加一級v帶傳動,但由于對改造中的支承設計不合理而失敗的情況也時有發生。

There are many large - size air hammers , blast furnaces and costing equipment including all sorts of heat treatment equipment , costing equipment including all sorts of heat treatment equipments 我們有大型空氣錘多臺,有足夠的冶煉高爐鑄造設施有淬火退火回火各種熱處理設備。
