Pipe-laying construction method under road surface for fluid heating road snow melting system

Abstract

The invention provides a pipe-laying construction method under a road surface for a fluid heating road snow melting system. The method includes a straight pipe type pipe-laying construction method anda coil pipe type pipe-laying construction method; the straight pipe type pipe-laying construction method adopts a pipe to cross pipe-laying construction of the road surface, needs to pass through anadjacent concrete construction warehouse, first width is utilized as a construction warehouse and concrete is poured along a traveling direction of a vehicle, and in the case of no need to cross a road, each of construction warehouses are separately and independently constructed by utilizing second width as a unit; in the case of need to cross the road, multiple construction warehouses are simultaneously constructed at an interval, and when steel bars are bound and a formwork is supported, steel sleeves with a larger diameter than a heat exchange tube is pre-buried in the construction warehouses where concrete is poured first, and mortar for strengthening a thermal conductive material is filled in and added between the inner walls of the steel sleeves and the outer walls of heating tubes;and the coil pipe type pipe-laying construction method does not need to pass through the adjacent concrete construction warehouse, and concrete pouring construction of each of the construction warehouses is carried out independently, coil pipes of each of the construction warehouses are an independent system, and a flexible connection is established between the adjacent construction warehouses y employing PE pipes.

Description

technical field [0001] The invention relates to a construction process for laying pipes under the road surface of a fluid heating road snow melting system, in particular to a construction method for laying pipes under the road surface under the condition of jumping warehouse construction. Background technique [0002] Snow on the road surface will greatly reduce the efficiency of transportation, increase the probability of traffic accidents, and cause serious losses, and snow is not allowed to freeze on some special-purpose roads, such as highways, aircraft roads, and aprons. Therefore, people have been studying various scientific and reasonable snow and ice removal technologies on the road surface. At present, the commonly used snow melting and ice melting methods at home and abroad include the clearing method and the melting method. The removal method is divided into two types: manual removal method and mechanical removal method; melting method includes chemical melting m...

Problems solved by technology

[0004] Research has found that for some special-purpose roads that are long and wide, conventional road construction techniques cannot effectively solve the problem of super-large, super-long, and super-wide concrete cracks. Every 5m is a pouring bin, and the jumping bin concrete is poured first, that is, every other span is poured, and when the strength of the jumping bin concrete reaches more than 80% of the design strength, the filling concrete is poured

The "jump warehouse method" construction solves the problem of super large concrete construction joints, and also puts forward high requirements for the construction technology of the pipeline under the pavement
