The steam acts upon the surface of the water in the receiver, which surface only being heated by the steam, it does not condense, but the steam gravitates or presses with an elastic quality like air, and still increasing its elasticity or spring, until it counterpoises, or rather exceeds, the weight of the column of water in the force pipe, which then it will necessarily drive up that pipe; the steam then takes some time to recover its power, but it will at last discharge the water out at the top of the pipe You may see on the outside of the receiver how the water goes out, as well as if it were transparent; for, so far as the steam is contained within the vessel, it is dry without, and so hot as scarcely to endure the least touch of the hand; but so far as the water is inside the vessel, it will be cold and wet on the outside, where any water has fallen on it; which cold and moisture vanish as fast as the steam takes the place of the water in its descent.

&&蒸汽行为后，水面在接收端，而只是表面被加热水蒸汽，它不浓密，但相互依赖蒸汽或印刷机具有弹性质量一样的空气，并仍在增加其弹性，或春天，直到它网，而超过重量栏水警队管道，然后它一定会推到管；蒸汽则需要一段时间来恢复其权力，但它会在最后排放水出顶管，你可以看到外面的接收机如何当然水，以及如果它的透明度；，目前为止由于蒸汽载船，它是未经干燥，所以作为热几乎要忍受至少触摸的手；但到目前为止，由于水内的船只，将寒冷和潮湿对外面，那里没有水落下；其中寒冷和水分消失快蒸汽需地方水在其后裔。

In the way of prophase preparing, this paper emphasizes the importance of full collecting inhering under pipe using no-dig horizontal directional drilling paving in the busy street and emphasizes the exploration technology being the main mean of inhering under pipe. Thus it can provide the main pledge measure of under pipe security and operator security.

历经十多年艰苦创业，企业拥有固定资产2000多万元，占地面积35000平方米，建筑面积20000平方米，4条双壁波纹管生产流水线，2条加筋管生产流水线，6条PE光缆护套管流水线，2条非开挖PE顶管流水线，年生产能力达万吨规模，年产值突破1亿元。

Therefore, we developed a call "NaMi-863" of thermoplastic pipe (the franchise has been granted, state: ZL200620009651.8) It is mainly iron pipes do not solve the basic acid-fast, short life-corrosion flaws , As long as 50 years of its life, but also a metal pipe to solve the water pollution, never to corrosion, but also solved the general strength of small plastic pipe, the flange-shedding and other shortcomings, and its strength has greatly exceeded its design Requirements, specifications and the same iron pipes, iron pipes is the alternative.

因此我们研制出一种叫&NaMi-863&的热塑钢管(已被国家授予专利权号：ZL200620009651.8)它主要解决了铁管不抗酸碱性，易腐蚀寿命短的缺点，它的寿命长达五十年，同时也解决了金属管子对水的污染。它永不腐蚀，也解决了普通塑料管强度小、法兰盘易脱落等缺点，它的强度大大超过了其设计要求，规格与铁管相同，是铁管的替代品。

Following, a experiment has been carried out, the incident waves with a frequency band of 200kHz-3 50kHz are used to the experiment, and a series of peak value-time curves are drawn each 10kHz, corresponding time are found through fitting peak value, thus the position of the defect is calculated accurately. The application of awl-shaped sensor head in the heat change water pipe experiment indicates that the ultrasonic guided waves may transmit nearly 50 meters in the pipe, which is not influenced by the elbows and makes it possible to test defects in long distance and large-scale. The water-load pipe experiment indicates that the displace and energy maybe leakage at the near-surface, which is significant for the further research.

而后，采用200kHz至350kHz频段的入射波进行了实验验证，并每隔10kHz绘出一条峰值一时间的曲线，通过拟合峰值点，找到对应的时间，从而准确的计算出了缺陷的所在；应用锥形探头的热交换水管的实验表明，超声导波可以在管道中传播了近50米的距离，且不受弯头的影响，从而使得长范围、大规模检测成为可能，水载管实验说明了离面位移和能量可能会发生泄漏的特性，为导波的深入研究和应用作了铺垫。

Pipe heat causes linesr expansion and rurtherresult in tensile stress in the direction of pipe xale to make cracks in direction perpendicular to the axle,in the case ,the stress value is obtained by ormula=E,and if ,it is estimated with 15mm LG PEX-A Pipe as base,the sectional breaking rorce is estimated approx.7.6kg/cm2,being much more little comparing with the concrete bearing force=1,536kg/cm2and its not needed to be anxious to concrete cracking rising.

由于管子的线性热膨而使管子受轴向伸长力，从人在与管轴成直角的方向上产生裂缝，这时的应力接计算，PEX－A按直径15mm标准计算进断面破坏强度约为7.6kg/cm2，比混凝土的支持力1.58kg/cm2小得多，所以不需要考虑管子对混凝土的破坏作用。
