液压顶管机规定说明

发布时间:2020-10-25人气:

液压顶管机组主要结构由四大部分组成,主体部分:主要由两个双作用液压油缸组成。液压泵站:分别配有柴油机泵站和电动机泵站。支撑板:作用是固定机器和支撑坑壁。顶杆与拉头:作用是顶进和回拖扩孔。该系列产品型号主要有:60T/3、80T/3、100T/3、120T/3,扩孔直径≤φ850mm,施工距离≤120米。该机操作简单,使用寿命较长,维修方便是中小型非开挖工程施工单位的必备工具。

液压顶管机规定说明

随着我国现代化进程的(de)脚(jiao)步,液(ye)压(ya)(ya)(ya)(ya)顶(ding)(ding)(ding)管(guan)(guan)机(ji)(ji)已成为非开挖觉工(gong)程中(zhong)的(de)主(zhu)角,具有工(gong)程速(su)度快,并(bing)且不破(po)坏路面的(de)优势,与传统的(de)顶(ding)(ding)(ding)管(guan)(guan)机(ji)(ji)相比(bi),液(ye)压(ya)(ya)(ya)(ya)顶(ding)(ding)(ding)管(guan)(guan)机(ji)(ji)无疑优势巨大,工(gong)作效(xiao)率是传统顶(ding)(ding)(ding)管(guan)(guan)速(su)度的(de)十几倍,并(bing)且液(ye)压(ya)(ya)(ya)(ya)顶(ding)(ding)(ding)管(guan)(guan)机(ji)(ji)的(de)顶(ding)(ding)(ding)杆采(cai)用注(zhu)水顶(ding)(ding)(ding)杆,通(tong)过注(zhu)水的(de)方式将工(gong)程中(zhong)残留的(de)昵图变成泥浆排(pai)出,减小了摩擦保(bao)护设(she)备的(de)使用寿命(ming)以及改变土地(di)的(de)韧性,提高了工(gong)程的(de)方便,液(ye)压(ya)(ya)(ya)(ya)顶(ding)(ding)(ding)管(guan)(guan)机(ji)(ji)可自行(xing)设(she)计行(xing)进进程,拥有自动回托功能(neng),实现主(zhu)机(ji)(ji)和变速(su)箱一体的(de)特点,让液(ye)压(ya)(ya)(ya)(ya)顶(ding)(ding)(ding)管(guan)(guan)机(ji)(ji)更为灵活,液(ye)压(ya)(ya)(ya)(ya)顶(ding)(ding)(ding)管(guan)(guan)机(ji)(ji)发展前景广阔,市场空间巨大。

顶(ding)管施工技(ji)术始于1896年美国的太平洋铁路铺设工程的施工中。1948年日本(ben)第一(yi)(yi)次采用(yong)(yong)顶(ding)管施工的方法(fa),在尼崎市的铁路下顶(ding)进了(le)一(yi)(yi)根内(nei)径600mm的铸铁管,顶(ding)距(ju)只有6m。欧洲发达国家(jia)最早开发应(ying)用(yong)(yong)顶(ding)管法(fa),1950年后,英(ying)德日等国家(jia)相(xiang)机采用(yong)(yong)。

液(ye)压顶(ding)(ding)管(guan)机(ji)作为非(fei)开挖(wa)工(gong)(gong)具被广泛(fan)应用的(de)顶(ding)(ding)管(guan)施工(gong)(gong)领(ling)域后(hou),极(ji)大的(de)改善了原有(you)施工(gong)(gong)工(gong)(gong)艺(yi)中(zhong)对路面挖(wa)掘(jue)的(de)种(zhong)种(zhong)困难(nan),顶(ding)(ding)管(guan)施工(gong)(gong)法是先(xian)在工(gong)(gong)作井(jing)内设(she)置支座和安装主(zhu)千斤(jin)顶(ding)(ding),所需铺设(she)的(de)管(guan)道紧跟在工(gong)(gong)具管(guan)后(hou),在主(zhu)千斤(jin)顶(ding)(ding)推力的(de)作用下工(gong)(gong)具管(guan)向土层内挖(wa)进,这样就绕开了对路面的(de)破坏,可(ke)以说是创(chuang)新性(xing)的(de)尝(chang)试。这其中(zhong)液(ye)压机(ji)构起到(dao)了不可(ke)替(ti)代的(de)作用。
