中文拼音 [liángdūnshēndù]
量噸深度
英文
tonnage depth-
Mechanical impact dynamics is used to analyse the production and spread of stress wave when hydraulic pile hammer hammerblows piles, the stress wave influence the course of driving pile. slender hammer that is equal to wave resistance of the pile can bring ideal stress waveform. when the hammer weight is constant, efficiency of driving pile can be increased by means of selecting drive cap and cushion pad of different rigidity to match the hammer according to various geological condition and the pile. the structure and principium of hydraulic system of double - acting hydraulic pile hammer with double cylinders is studied in detail in the paper, the hydraulic system and electric control system of six - ton - double - actin hydraulic pile hammer with double cylinder is designed on the basis of it
本文應用沖擊機械繫統動力學分析打樁過程中錘體與樁撞擊時應力波的產生、傳播以及該波對沉樁過程的影響。認為與樁等波阻的細長狀錘體能夠產生理想的應力波波形；在樁錘重量一定的情況下，可針對不同的地質情況和樁，通過選擇不同剛度的樁帽和樁墊與其匹配來提高打樁效率。本文對雙缸雙作用液壓打樁錘液壓系統的結構和工作原理進行了深入的研究，並在此基礎上設計出六噸雙缸雙作用液壓打樁錘的液壓系統和電控系統。But during long time, it is very difficult for the exploration and development of sandstone oil layers on the upper part of the fouth member of shahejie formation. it is mainly represented as it ca n ' t be got the optimum production test effect and ca n ' t keep long term rate - maintenance
該區深層沙四上段砂巖油層的勘探開發一直存在較大的難度，集中體現于不能有效獲得最佳試采效果並長期穩產，產量有時在短短幾天內可由數十噸降至工業品級之下。
