回填

About FRP pipe Pressure Test, we hope Timas can cooperate with us, if it can't be backfilled on time, which will affect steam drum hoisting and plate girder entering plant.

关于 F.R.P 管道试压一事，望 Timas 积极配合，如不能及时回填，将会影响汽包，大板梁进厂。

The results show that the concentration of displacement and stress in surrounding rock intensifies with the increase of excavation steps. The maximum compression and tension stress reach 54 MPa and 3.9 MPa, which are close to the peak strength of surrounding rock. When the tailings are backfilled, the magnitude of floor heaves reduces about by 5 mm, and the maximum compressive stress drops to 32 MPa. Distribution of both stress and displacement fields are improved and the stability of stopes can be ensured during the mining process.

研究结果表明：随着开挖逐步推进，围岩位移不断增大，应力集中现象明显，最大压应力达54 MPa，最大拉应力达3.9 MPa，接近围岩的极限强度；在尾砂回填后，底鼓量下降5 mm，最大压应力降至32 MPa，表明应力场和位移场均得到改善，能确保回采期间采场的稳定。

It works by choosing appropriate gravel, scree, talus decries, coarse sand, medium sand, then ram them to be closely knitted. The sand gravel cushion can increase the bearing capacity of weak groundwork.

这种垫层法是用碎石、卵石、角砾、圆砾、砾砂、粗砂、中砂或石屑等坚硬、较粗粒径的回填材料，经合理级配并夯压密实后形成持力垫层，其主要目的是为了提高浅层软弱地基或不均匀地基的承载力。

Based on theoretical analysis, a three dimensional non-linear finite element program is developed to examine the effects of alleviating bridge approach differential settlement by emplacing geogrids in the backfill behind bridge abutment. After analyzing the character of stresses and displacements within backfill behind bridge abutments and the interfacial friction action between geogrids and fillings, mechanism of using geogrids to reduce differential settlement is obtained.

在理论分析的基础上，利用有限单元法编制了土工格栅处理路桥过渡段差异沉降的三维非线性有限元程序，并结合工程实例对台背回填的三维性状进行系统分析，研究了铺设土工格栅对台背填土位移场和应力场的影响，分析了土与格栅界面剪应力的大小和分布，从土与格栅的界面作用阐述了减小沉降差的机理。

Pneumatic hammer is optional to carry out the construction of pilot bore in gravels, rocks and backfills.

可选配气动冲击锤，用于卵砾石、岩石和回填杂土中导向孔的施工

One stage has included filling of 3000 vials and stoppering on line; another stage included filling 3000 vials, transportation to the lyophilizer and then stoppering; a third stage included the filling of 3000 vials, loading in the lyophilizer, and exposure to a portion of the nitrogen flush and then stoppering.

第一部分是灌装3000瓶并且加塞，第二部分是灌装3000瓶，传递到冻干机中再全加塞，第三部分是灌装3000瓶，排放到冻干机内，暴露在氮气流下冻干机的灭菌和用于回填的无菌氮气系统分别进行验证，培养基灌装主要验证灌装、传递和摆放的无菌操作。

Mechanical tampers shall not be used until backfill in place is at least 600 mm over the pipe.

回填高度到管道之上至少600毫米处方才可以使用机械压土机。

Cast box drain, backfill , remove bottom layer of strut , cast the drain wall.......

浇注排水方沟、回填、清理支撑底部土层、浇注排水墙。。。。。。

They weren't aggressive, but I yelled and threw a rock in their direction to get them off the trail and away from me, just in case.

他们没有侵略性，但我大喊，并在他们的方向扔石头让他们过的线索，远离我，以防万一。
