土钉墙与注浆技术
土钉墙与注浆技术1.1. 路堤灌浆技术摘自《中南公路工程》2001.3《灌浆法在高路堤稳定中的应用》由于浆液的扩散能力与灌浆压力的大小有关，而压力主要取决于路基的密实度、强度和初始应力。
钻孔深度、灌浆位置和灌浆液在地下流动的形式是：当灌浆压力较低时，路基填料的渗透性较好，水泥浆在中等浓度的情况下以渗流的方式渗入路基的孔隙。
这种方式可以认为路基原结构未受扰动和破坏，灌浆量及浆液半径常用渗流理论求解。
当压力逐渐加大，其他条件不变时，浆液的流动由层流转变为紊流，在紊流条件下的灌浆量与浆液扩散半径常用紊流理论求解。
上述两种情况称为渗入注浆法，适用于碎石土、沙卵土夯填料的路基。
在拈性土夯填的路基渗透性很小，渗入法灌浆难以达到预期目的，需要采用劈裂性灌浆。
第三种灌浆法是压密灌浆法。
通过钻孔向土中灌入极浓的浆液，使注浆附近土体压密而形成浆泡。
初始灌浆压力沿径向扩散，随着浆泡的扩大，便会产生较大的上抬力。
一般情况下都会使用两种或两种以上的灌浆方法，才能形成渗透-充填-置换-复合防渗补强的地基。
浆液配比大致为：水:料=1:（0.8-1.0）,水泥:粉煤灰=1:1。
浆液的扩散半径按下式计算：)(333r R khr nt -=β 如果R >r ，则: ()3/3n khrt R β=式中：t 为凝固时间，s ；k 为渗透系数，cm/s ；n 为空隙率，%；h 为注浆压力，Pa ；β为水与浆液之间的黏度比；R 为浆液扩散半径，cm ；r 为灌浆孔半径，cm 。
灌浆量计算：1000).1(B Vna Q +=式中：Q 为灌浆量，n 为孔隙率，%；a 为灌入充填率，%；V 为加固土体积，m 3;B 为损失系数，%。
1.2. 灌浆法施工应用施工程序为：布孔-钻机选型-下注浆花管-灌注施工。
灌浆压力和浆液浓度是保证灌浆质量的重要因素。
灌浆结束应以设计的终孔压力和平均单孔注浆量为双重控制标准。
单孔灌浆量=排距×孔距×孔深×填土孔隙率。
电动油泵说明书
一、产品型号、名称二、技术性能ZB4-500D型电动油泵技术性能三、构造简介本油泵为高压电动油泵，由泵体、组合控制阀、车体管路、液压控制回路等五部分组成。
1、泵体该泵系采用自吸式轴向柱塞泵。
电动油泵带动轴旋转，轴在旋转过程中，通过设置于该轴上的推力轴承逐次将柱塞压入油缸，而吸油弹簧靠其弹力时刻使柱塞贴紧在推力轴承端盖上，轴和弹簧的交替作用使柱塞在油缸中往复运动，在进、排两单向球阀同步配合下，便在出油嘴得到连续均匀的出油。
该泵共有6个油缸，圆周等分排列又交错分成两条排油路，每一排油路均由三个相间120°角的油缸组成。
两条排油路单独出油，各不相扰。
本泵头系阀式配流，斜盘式轴向柱塞泵，设有5XΦ10柱塞副，公称流量为2L/min，最高压力为50MPa。
泵头结构示意图如图1。
图1 泵头构造示意图2、控制阀整组控制阀是在原ZB4-500型电动油泵控制阀基础上增加比例溢流阀PMVP4-44/24及球式电磁换向阀VZP1D22-G24而成。
工作时把与P 口(在阀块上打有钢印)连接的原ZB4-500电动油泵一侧控制阀关闭，另一侧控制阀开启，系统的压力由比例溢流阀调定，压力的高低变化与控制电流的变化有关。
千斤顶的伸缩缸通过电磁换向阀的切换来实现。
3、控制回路4、油箱小车车体采用薄板焊接结构，油在下部，主泵直接浸入油中。
泵、阀和电动油泵与翻板系固定联接，高压管采用Φ9x2.5紫铜管及Φ6高压胶管，低压管采用Φ11x0.5透明塑料管和Φ6高压胶管。
油箱采用钢板焊接，容量约为42L。
小车安装固定轮及万向轮，转向灵活，运输轻便。
5、电器开关采用磁力开关，以减少负载时的启动电流。
四、使用与保养（一）灌油本油泵采用优质矿物油，油内不含水、酸及其他杂质混合物，粘度约为2～3，根据环境温度实际情况一般可采用液压油L-HM32（冬用）或L-HM46（夏用）灌油前需经过滤，并应把油箱、泵体管路等处清洗干净，否则泥沙铁屑等脏物带入将可能发生不正常的磨损和刮伤，甚至造成事故。
钢绞线张拉工艺流程
预应力筋张拉施工工艺流程介绍（6）张拉平台的搭设：应在张拉端设置张拉平台，平台平面方向沿预应力束方向至少2.5m，宽度约为1.5m，平台高度应低于预应力束500mm左右，以保证张拉顺利进行。
（7）构件端头清理及钢绞线清理。
（8）动力电源及照明电源的布置：驱动油泵电源为380V，配电盘至少15A，要求电源拉至张拉平台位置。
（9）张拉班组布置及安全技术交底。
（10）工具锚、限位板、顶压器等配套设备及配套工具准备完毕。
二、张拉顺序预应力筋的张拉顺序，应考虑结构的受力特点、施工方便、操作安全等因素确定。
当框架结构的主次梁均施加预应力时，应先张拉次梁，后张拉主梁。
梁中预应力筋的张拉应左右对称进行。
三、预应力筋张拉程序首先从零加载至量测伸长值起点的初拉力（10％δcom），然后分级加载至所需的张拉力。
四、预应力筋张拉1、清理垫板及钢绞线表面的灰浆；2、安装锚板，夹片；3、千斤顶就位，千斤顶上的工具锚孔位与构件端部工作锚的孔位排列要一致，；5、工具锚夹片打紧，将夹片均匀打紧并外露一致；6、油泵供油给千斤顶张拉油缸，并随时检查伸长值与计算值的偏差。
6、张拉到规定油压后，持荷复验伸长值，合格后实施锚固7、千斤顶活塞回程；8、拆除千斤顶；9、切除多余的钢绞线；五、预应力的张拉管理1、预应力筋的张拉管理，采取应力控制，伸长校核。
实际伸长值与计算伸长值的允许偏差＋10％，-5％。
如超过该值，应暂停张拉；采取措施予以调整后，方可继续张拉。
如伸长值偏小，可采取超张拉措施，但张拉力限值不得大于0.8fptk值。
2、锚固阶段张拉端预应力筋的内缩量允许值应不大于5mm。
六、张拉操作要点：1、张拉前安装锚具时必须把梁端埋件清理干净，先装好锚板后装夹片；2、组装张拉设备顺序是先装限位板，后装第二块限位板。
限位板必须和千斤顶相匹配，从而确保张拉力的作用线和预应力筋末端中心线一致；3、张拉时，要严格控制进油速度，要求缓慢、均匀、平稳；4、张拉过程中，应认真测量预应力筋的伸长值和张拉力，进行“双控”并作好记录；双控法张拉注意事项张拉注意事项（1）钢绞线张拉前应全面检查锚具、千斤顶及油泵等张拉设备的性能、型号、数量等是否附合设计和施工要求。

Refer to Repair/ ConversionKit Numbers, page 4.INSTALLATIONMounting Position. Pump may be mounted in any position. When mounting vertically, it is necessary to keep bearings above seals to prevent possible seal leakage into bearings.Pre-Wetting. Prior to connecting pump, wet pump elements and mechanical seal by adding fluid to be pumped into suction and discharge ports. Turn pump over several times in a clockwise direction to work fluid into pump elements.Piping. Piping to pump should be self-supporting to avoid excessive strain on pump housings. See Table 1 for suction and discharge port sizes of each pump model.Use pipe “dope” or tape to facilitate disassembly and to provide seal on pipe connections.Electrical. Follow the wiring diagram on the motor nameplate or inside the terminal box for the proper connections. The wiring should be direct and conform to local electrical codes. Check power connections for proper voltage. Voltage variations must not exceed + 10% of nameplate voltage. Motors do not have overload protection.To prevent damage to pump, pump rotation must be clockwise when facing pump from motor end. OPERATIONSelf-Priming. With wetted pumping elements, the pump is capable of 25 ft. suction lift with pipe size equal to port size. Be sure suction lines are air tight or pump will not self-prime.DO NOT RUN DRY. Unit depends on liquid pumped for lubrication. For proper lubrication, flow rate should be at least 10% of rated capacity.Pressure and Temperature Limits. See Table 1 for maximum discharge pressure of each model. Unit is suitable for service at temperatures shown in Table 2.Storage. Always drain pump for extended storage periods by removing bottom drain plug.

DTYPE KEY AND CURVE SPECIFICATIONS 50Hz PERFORMANCE CURVE SPECIFICATIONS The specifications below qualify the curves shown on the following pages.Tolerances according to ISO 9906 Annex AThe curves refer to effective speed of asynchronous motors at 50 HzMeasurements were carried out with clean water at 20°C of temperature and with a kinematic viscosityof ν = 1 mm 2/s (1 cSt)The NPSH curve is an average curve obtained in the same conditions of performance curves.The continuous curves indicate the recommended working range. The dotted curve is only a guide.In order to avoid the risk of over-heating, the pumps should not be used at a flow rate below 10% of best efficiency point.Symbols explanation:Q =volume flow rateH =total headP 2=pump power input (shaft power)η=pump efficiencyNPSH =net positive suction head required by the pumpMEI =minimum efficiency indexThe minimun efficiency index (MEI) is a measure of the quality of a pump size in respect to its mean efficiency. The minimum efficiency index is based on the hydraulic efficiency and on the head at the best efficiency point.The efficiency of a pump with trimmed impeller is usually lower than that of a pump with the full impeller diameter. The trimming of the impeller will adapt the pump to a fixed duty point, leading to reduced energy consumption. The minimum efficiency index (MEI) is based on the full impeller diameter.The operation of these water pumps with variabile duty points may be more efficient end economic when controlled, for example, by the use of a variable speed drive that matches the pump duty to the system.204Rev.

预应力混凝土施工(先张法、后张法)
2.消除应力钢丝 采用消除应力的矫直回火钢丝，可消除钢丝冷拔中产生的 残余应力，提高钢丝的比例极限、屈服强度和弹性模量， 并改善塑性。消除应力钢丝按外形分为光面、刻痕和螺旋 肋钢丝。直径4 ㎜～9㎜；1570 、 1670和1770MPa；弹 性模量2.05 ×105N/mm2 。
3.热处理钢筋 对某些热轧Ⅳ钢筋（如40Si2Mn、48 Si2Mn、45 Si2Cr 等）经调质处理而形成的高强度无明显流 幅的硬钢。利用热轧钢筋的余热进行淬火，然后 再中温回火等热处理后形成的。 直径6 ㎜、8.2 ㎜ 、10㎜；1470MPa；弹性模量 2.0 ×105N/mm2 。

为什么要使用预应力混凝土？
混凝土的抗拉极限应变值只有0.0001～0.00015㎜, 要保证混凝土不开裂，钢筋的应力只能达到20～ 30N/mm2；即使允许出现裂缝的构件，当裂缝宽度 限制在0.2～0.3㎜时，钢筋应力也只能达到150～ 250N/mm2,使高强钢筋的强度无法充分利用。
2.张拉设备
液压张拉千斤顶和电动油泵 穿心式千斤顶：常用YCW千斤顶 ，1000－4000KN；适用 于张拉FVM夹片群锚、DM型镦头锚等 拉杆式千斤顶：可张拉DM型螺丝端杆锚、JLM精轧螺丝钢 锚具，LZM冷铸锚等。 锥锚式千斤顶:仅用于带钢质锥形锚具的钢丝束。
