Device and method for water insulating test of horizontal sealing bottom of foundation pit

Abstract

The invention discloses a device and a method for the water insulating test of a horizontal sealing bottom of a foundation pit. The device comprises a test box arranged at the upper side of a base, wherein the test box is an internally hollow cuboid, a plurality of feet are fixedly connected between the lower side wall of the test box and the upper side wall of the base, a plurality of rollers aremounted on the lower side wall of the base, the middle of the test box is provided with a bottom sealing plate, a clamping mechanism is arranged between the bottom sealing plate and the inner wall ofthe test box, the top of the test box is provided with a sealing top, the inner top of the test box is provided with a fixing mechanism, a partition board is fixedly connected to the inner wall of the inner bottom of the test box, and a mounting opening is formed in the middle of the partition board. The device and the method have the advantages that water pressure is changed through a water pressure test pump, the position of a water outlet is changed through an electric telescopic rod, joint analysis is carried out on the water insulating performance of the bottom sealing plate by combiningthe variation of various variables, and the test of the water insulating properties of the bottom sealing plate is more accurate.

Description

Technical field [0001] The invention relates to the technical field of horizontal bottom sealing of foundation pits, in particular to a water-proof test device and method for horizontal bottom sealing of foundation pits. Background technique [0002] The measures to seal the bottom of the independent foundation pit is to use the specified concrete cushion to avoid long-term exposure of the bearing layer to the atmosphere and muddy water pollution before the foundation is poured, and to facilitate cleaning. At the same time, the pile foundation is protected to prevent the bearing layer from being exposed to the atmosphere for a long time before the pile foundation is poured. , The rock formation is weathered, and it is easy to remove flooding. [0003] Therefore, at present, the horizontal back cover water resistance test device is generally used to test the water pressure resistance of the back cover to ensure the pressure resistance performance of the back cover. The current test ...
