碎石

The experiment uses 100% city garbage melting slag instead of nature macadam and sand to make concrete specimens, under homoiothermal (20±2)℃ and constant humidity relative humidity (60±5)%, which dry and shrink freely 180d. The results show, comparing with common concrete specimens, whose drying shrinkage length valuable rate and mass loss rate change a little.

试验以100 %城市垃圾熔渣骨料替代天然碎石和砂子制备城市垃圾熔渣混凝土试件，在恒温(20±2)℃，恒湿相对湿度(60±5)%的试验室内使混凝土试件自由干燥收缩180 d，试验结果，城市垃圾熔渣混凝土试件与对比用的普通混凝土试件相比，干燥收缩长度变化率以及质量损失率相差不大。

The skin puncture point had been located in this scope: the 10th or 11th intercostals, inner from postaxillary line and out of infrascapular line. The targeted puncture access is superior posterior calyx under B-ultrasound guidance. The lithotripsy device which we employed was U-100 Frequency-Doubled Double-Pulse Nd:YAG laser.

But the strata with high ground water level are composed of alluvium clays、 silty clay、 gravels and crushed stone soils in Chengdu;And the shield will drive in the interzone with complicated geologic environment, especially in the strata contained more than 50 percent of gravels which diameter is greater than 5cm, also contained big grain size gravels(the maximum diameter is about 1m)、 cement gravels and silty sand with lentoid mass;And on the ground there have many serried buildings in the prosperous zone.

而成都地铁工程将主要穿越由冲积粘性土、粉土、砂砾和碎石类土组成的覆盖层，地下水位高，盾构将通过大量地质条件和环境条件均极为复杂的区间，特别是地层中还夹杂有大漂石、胶结砾石层、粉细砂透镜体，隧道围岩中直径大于5cm的砾石含量一般都在50%以上，最大的漂石直径达1m左右，且地面多为建筑物密集的繁华地区，施工难度大，国内尚无先例，在国外也无完全成熟的经验。

This system adopts unique patent "the integral orbit weighing system",(patent number: 03277805.8) whose steel frame can be placed levelly on the crushed stones way or railroad to weigh various large calculating equipments, and can weigh the size of top dynamic loading, passing microcomputer to figure out data, and data store, statistics, net-connecting and auto printing.

采用独特专利&一体化称量轨&，（专利号：03277805.8），利用剪切应变取代正压应变，衡区采用钢制框架线路，钢制框架平放在碎石道床上，安装在铁路线上，对铁路各种货车进行动态连挂称重的大型计量设备，它能准确地检测到称重轨上动态载荷的大小，通过微机，计算出各种等数据，并可完成数据自动储存显示、统计、联网、打印等多项功能。
