Description

Technical Field

[0001] The utility model relates to the technical field of underground floor plate pile head waterproofing, in particular to an underground floor plate pile head waterproofing structure. Background Art

[0002] The current construction process of underground waterproofing in construction projects is: first drive each pile into the soil, and then dig the soil down to a predetermined depth. At this time, most of the pile is still buried in the soil. After digging, cut off the excess part on the top of the pile, and then tamp the bottom base soil layer. The base soil layer has groundwater that surges upward, and then lay a concrete cushion layer on the base soil layer. This concrete cushion layer is usually five centimeters thick. The concrete cushion layer is above the underground floor. Laying the concrete cushion layer is convenient for construction workers to construct and avoid construction workers directly stepping on the loose base soil layer. Then, lay a waterproof layer above the concrete cushion layer. The material of this waterproof layer is plastic or rubber. Then apply waterproof mortar or waterproof glue to the gap between the waterproof layer and the outer wall of the pile body, and finally make the reinforced concrete foundation required for the basement on the waterproof layer.

[0003] Regarding the construction process of the above-mentioned waterproof structure, the inventors found in actual operation that water seepage is prone to occur at the junction between the waterproof layer and the pile head. Therefore, we proposed an underground floor pile head waterproof structure. Utility Model Content
