Study On Ballastless Track Construction Technique

The paper set rightness shui-yu railroad have no residue orbit comprehensive experiment the segment carried on a following topic a research: Have no residue orbit construction technique; Have no the construction technique of residue orbit transition segment. Have no residue orbit reinforcing bar to mix a net construction technique. Have no residue orbit to mix a plank construction technique;Have no residue orbit to sink to decline to prognosticate a technique. Had no residue orbit to apply the method of"three stages, four blocks, eight processes" to carry on extensively in the process of being started construction of start constructio The key technique in which includes:The layering presses solid; The space grid establishes. The impact presses solid a mechanical choice etc.Have no the residue orbit transition segment construction technique is for solving different construct an of thing just a degree is even to assign with made the orbit degree just change gradually, and the biggest limit let up dissimilarity structure the thing transformed bad, attained assurance railroad train safety, steady and comfortable movement of purpose. Its key technique: How to mix to make the transition segment class to go together with crushed stones; How choose to press solid a machine tool; Information-based construction management. The construction process also adopted "three stages, four blockses, eight processeses".The technique of foundation's reinforcing using stake plank structure is to applied for the very first time in the no residue orbit railroad engineering by the domestic. The roadbed using Stake plank structure makes use of plank-stake-soil well, making the common function of the three come to contented railroad train carrying a camp astability and the characteristics of transforming.The key technique with structural net of the reinforced concrete stake: The dry method becomes a stake bore; The method of judging the depth which drills a hole into rock. The construction method of the prevention bore falling and reducing the crud of bore bottom..The construction craft of anti- to putting stake body reinforcing bar the cage in stake body. By the method of drilling a hole to infuse the concrete make it becoming a stake to have already filled of the five meters in height above railroad roadbed carryied on reinforcing. Making each single stake consociation become 1 to accept dint structure wholely, and undertaking the filling soil which are upper part of a net structure and railroad train lotus together.Rationality and technical adaptability of other foundation reinforcing technical, this engineering carried on succeeding of groping.
