錘擊打樁 的英文怎麼說
中文拼音 [chuíjīdǎzhuāng]
錘擊打樁
英文
impact pile driving-
Hydraulic pile hammer is one of the pile driving machines that drive prefabricated piles into the ground in the construction of pile foundation such as construction, bridge, dock, etc. with the development of science and technology, the prefabricated pile driving machines evolve from block hammer, steam - hammer, diesel hammer to hydraulic hammer. hydraulic pile hammer is one of ideal prefabricated pile driving machines because it can adjust stress waveform, decrease stress peak value, prolong effectual action when it drives piles. hydraulic pile hammer is used widely and formed series in developed countries now
液壓打樁錘是用於建築、橋梁、碼頭等樁基礎施工中打入預制樁的樁工機械。隨著科學技術的進步，預制樁施工機械由落錘、汽錘、柴油錘，發展到了液壓打樁錘。用液壓打樁錘打樁，可以調整撞擊應力波波形，減小應力峰值，延長有效作用時間，是一種比較理想的預制樁施工機械，目前在發達國家已被廣泛使用，並形成了系列化。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。Using high - strain dynamic tentative piling technique ， one can obtain the pile endpoint resistance at each hit in the process of hammering, which is the bearing capacity of the pile endpoint soil against the pile
運用高應變動力試樁法，可以獲得樁在打入過程中的每一錘擊下的樁端阻力，即樁端土對樁的端承力。Analytical solution for model of pile hammer impact
打樁錘擊模型的解析演算法The engineering practice proved that installation of caz combined steel sheet piles by driving with hammers is rational and feasible and the cost of driving is also effectively controlled
實踐證明錘擊法施工caz組合樁，其施工工藝是合理可行的，其打樁成本也得到了有效控制。Plc has small cubage, strong function, high reliability, ability to adapt abominable field environment of construct machine to face. in order to improve adaptive ability of hydraulic pile hammer to various soil, various finial velocity and dropping length must be obtained by adjusting time of lifting, dropping and keeping pressure that is accurately selected by the control system of plc
Plc體積小、功能強、可靠性高、能適應建築施工機械惡劣的野外環境。通過plc電控系統可以準確選擇不同的上升、下降和保壓時間，使得液壓打樁錘具有不同的下打高度，從而獲得不同的打擊末速度，提高了液壓打樁錘對不同土壤的適應能力。As the result of the development of technology of integration of mechanics, electron and hydraulic pressure, hydraulic pile hammer has been researched and manufactured since 1970 ' s because it could save energy sources and benefit environment. compared to such conventional hammer as falling hammer and pile hammer using diesel oil, it owned some advantage like high transmission efficiency, low noise, high piling energy and easy controling
液壓打樁錘從20世紀70年代中期開始研製，是世界各國對節能和環保問題重視以及機電液一體化技術發展的結果，與目前較常用的落錘、柴油錘相比，它具有能量傳遞效率高、噪音低、打擊能量高且易於控制等優點。Under the ordinance, construction activities are grouped into two categories and are controlled by means of a system of construction noise permits : general construction work for example, excavation, renovation, road work ; and
條例將建築工程分為兩類，並透過簽發建築噪音許可證的制度來管制a一般建築工程例如挖土裝修及道路工程及b撞擊式打樁工程例如使用油壓錘或吊錘。分享友人
