Abstract

The invention discloses a transverse groove walling crib provided with a fixed structure and a construction method of the transverse groove walling crib. A fixing structure which can firmly connect a walling crib support and a structure main body is formed at a backwater side of the walling crib support through vertical screw rods, slant auxiliary anchor bars and buckling auxiliary steel bars and combining of a base plate main bar and a structural steel bar and by embedded steel bars, bolted connection and welding and other multipoint connection methods. A slip casting pipe is applied to carry out secondary grouting on the basis of an original pouring concrete fixing walling crib. According to the transverse groove walling crib provided with the fixed structure, firming degree of fixing of the transverse groove walling crib is enabled to be greatly improved, fixing quality and durability of the walling crib are improved, effect on roads and driving due to damage and invalidation of the walling crib fixing structure is reduced, the walling crib can still keep fixed and firm after a transverse groove is put into use, the connection part of the walling crib and a concrete well chamber structure main body is durable, smoothness of road surface of underpasses and a tunnel is improved, and guarantees for safety of driving are provided.

Description

technical field [0001] The invention relates to a water collection and drainage facility, in particular to a cross-cut ditch well circle and a construction method thereof. Background technique [0002] Due to the large longitudinal slopes in tunnels and tunnels, in the event of precipitation, the rainwater will rush down from the top of the slope at a relatively fast speed. Correspondingly, it is necessary to adopt facilities that can quickly collect and drain water on slope roads , in order to collect and discharge the incoming water on the slope in time, the cross-section ditch is a part of the water collection and drainage facilities on the road surface. The characteristic of the cross-cutting ditch is full-section water collection and drainage, so it has the advantage of rapid drainage, but at the same time, an inevitable disadvantage is that each cross-cutting ditch can only collect the incoming water from its upstream, and there is still a small amount of water that wi...
