Therefore,<a href="http://www.mulberrytaskeroutlet.com" target="_blank" class="postlink">mulberry taske</a>, pre-drilling site requirements should be lower than the venue for the elevation of the road 50cm, and a reliable collection of mud, drainage system and to ensure sufficient smoothness, strength in order to ensure the smooth progress of drilling work. 4_2 most difficult hole is drilled through the gravel layer, gravel layer will determine the size and thickness of the hole, into the progress and quality of larvae L, the current method is often used with vacuum pumps or eccentric drilling through thick gravel layer . Therefore should be fully informed before drilling geological conditions, prepared to deal with the difficulties of preparation. Construction technology exchange will bring great difficulties bottom,<a href="http://www.edhardymexicos.com" target="_blank" class="postlink">imagenes ed hardy</a>, bottom water layer is also almost impossible to affect the structure of construction project quality and progress, the party must supervise the construction side management in strict accordance with the program called for the implementation recharge. 4.5 As the level of horizontal pipe laying pipe joints should not stay set, so the level of civil cushion pipe construction will have a major impact the construction schedule,<a href="http://www.edhardysuomessafi.com" target="_blank" class="postlink">ed hardy vaatteet</a>, so the arrangements for civil construction should take full account of the level of pipe construction. Horizontal pipe trench construction is usually not standardized, mainly in the groove depth, which affects the slope can not meet the requirements of cushion thickness, and spread the bottom material, cover often can not meet the regulatory requirements affecting the level of protection and regulation of tube, so Management shall strengthen the cushion cover pre-construction inspection. 4.6 product protection when digging the earth excavation machinery may be pulled hard enough to the U-tube U-tube damage caused by basement cushion construction, insulation board construction, concrete support break, outside the basement backfilled and so may be u- pipe damage, so the construction process should be established to ensure reliable protection of the finished product U-tube protection. And outdoor buried pipe should also be strictly good anti-corrosion, insulation and other special protection to ensure that the U-tube product quality. 4.3U-tube u-tube producing 5 Conclusion The main issues include the production of u-tube the bottom of the protective measures in place, u-tube no reliable measures to separate the two tubes, so the next pipe is not in place, such as hot-melt joint appearance of poor quality issues, which need to be managed prior to its acceptance criteria established to strictly control production quality. 4.4 Although the recharge recharge underground pipe system to the entire impact of the final result is very large,<a href="http://www.franklinandmarshalluk.com" target="_blank" class="postlink">franklin and marshall clothing</a>, but the practical operation of view, the implementation of this work were very irregular. Construction side of the system are often not required with the filler, and no mechanical compaction grouting to ensure the filling, puree filling is often used, but also makes the recharge non-existent, recharge is poor, the rich underground water strata encountered in this paper on the ground source Heat Pump U-tube pipe systems and pipe laying work in the level of quality control points and easy problems are briefly summarized. As the feature differences between the project and therefore can not generalize, but as a new ground-source heat pump technology, the management should be combined with engineering and quality control points in accordance with specifications set to ensure maximum end-use results.
