The utility model belongs to the technical field of turn bridge turn system mounting, and particularly relates to a construction device for matching of sand in a temporary sand box of a turn bridge and closed water insulation. The problem that in the mounting and construction process of an existing turn bridge turn system, switching of a turn bridge stress system cannot be completed in time, and consequently, the construction period is delayed, and the turn system is damaged is solved. The construction device comprises an inner sand box sleeve and an outer sand box sleeve which are arranged vertically, the lower portion of the inner sand box sleeve is sleeved with the outer sand box sleeve, No.1 lithium-based grease is adopted as an oil seal in a clearance opening between the inner sand box sleeve and the outer sand box sleeve, a quartz sand filling layer is arranged between the outer bottom of the inner sand box sleeve and the inner bottom of the outer sand box sleeve, and a sand extraction opening is formed in the outer side of the bottom of the outer sand box sleeve, adopts No.1 lithium-based grease as an oil seal, and is plugged by a sand baffle. The influence of the situation that the temporary sand box is uneven in settlement, prone to hardening and hard to remove on construction of the turn bridge is reduced, and the construction procedure and period of the turn bridge and the stability of the turn steel structure in the turning process are guaranteed.
