On-site casting method for bottom peg burying in preformed grille under seaside levee

Abstract

An on-site casting method for bottom peg burying in a preformed grille under a seaside levee includes the steps of burying pegs until the tide is out in the daytime, hurrying to select a proper area in a foundation of a riprap slope 3 at the bottom of a wave-resistant grille (2) when a construction part inside a retaining wall (1) is completely under a water level (5), and ditching foundation ditches used for peg burying through manual work. The on-site casting method for the bottom peg burying in the preformed grille under the seaside levee has the advantages that stone riprap under a seaside preformed unit is taken as a foundation, a plastic film-covering sand-pressing method is utilized on a seaside and a riverside, a concrete cast-in-place mode is adopted to bury survey marks, the method completely utilizes on-site natural conditions to ingeniously achieve under-water concrete cast-in-place successfully on a windy and wave-surfing slope of the seaside and the riverside under the conditions that the wave releasing measures of dewatering, well sinking and the like are not utilized, and the construction technology is money-saving, time-saving, successful at the first time, capable of being applied to peg burying projections of deformation monitoring along a river wall and a sea wall, and wide in application prospect.

Description

technical field [0001] The present invention relates to the field of making measurement markers on the seaside using prefabricated grids to hold down a large number of riprap rocks to make slopes for wave-proof slopes, in particular to a method for on-site watering of measurement markers buried in the bottom of prefabricated grids under seaside flood control embankments . Background technique [0002] Measuring marker stones are moved and buried in plains or mountains, etc. In the mud ponds by the river, especially at the seaside, the breakwaters are washed and submerged by waves without damaging the prefabricated grille, which is rarely done in the past. If you want to bury the measuring marker stones at the bottom of the prefabricated net, firstly, you must lift the grid or damage the grid to bury it. If you do that, you need to use a crane, which will damage the foundation due to the high cost. Second, add water reducing agent, Early strength agent and other measures to ...

AI Technical Summary

Problems solved by technology

[0003] The pouring of concrete marker stones cannot be combined with prefabricated grids. The time for burying markers is very tight every day. The newly buried marker stones will be washed and submerged by the waves of high tide at any time. When the poured concrete marker stones do not reach the strength after initial setting, If the marker stone is washed and submerged, the water-cement ratio of the concrete will change, the cement slurry will be lost, and the concrete will even be washed away, which will seriously affect the quality of the concrete marker stone foundation, and even cause the marker stone to be scrapped.
