Description

Basement ground drainage structure Technical Field The utility model relates to the technical field of constructional engineering, in particular to a basement ground drainage structure. Background In the construction engineering, the underground structures such as basements and the like are often subjected to the risk of water leakage due to the fact that the underground structures are in an underground water environment for a long time or are influenced by other water sources, and the positions such as bottom plates and walls of the underground structures, particularly weak links such as construction joints and post-pouring belts, are frequently exposed to the risk of water leakage. In order to effectively prevent and solve the leakage problem of the underground structure, and ensure the safety and the use function of the structure, a drainage system is usually preset or drainage measures are adopted at the key positions. Currently, underground structures are used in which hydrophobic passages are provided, which collect moisture that may penetrate into the interior of the structure and guide it to a designated location such as a water collection well in an organized manner for drainage. However, in some existing hydrophobic tunnel designs and constructions, it is possible to employ or be adjacent to members comprising metallic materials, such as by using the rebar of the structure itself as a securing support, or the hydrophobic tunnel itself comprises metallic components. Under the underground humid environment, the metal components, whether the original steel bars of the structure or the newly added metal components of the hydrophobic system, are easy to rust. After metal rusting, the volume of the product is usually obviously expanded, and the expansion force can generate extrusion damage to the surrounding concrete structure or the hydrophobic channel, and over time, the structural integrity of the hydrophobic channel can be damaged, deformed and cracked, even the preset hydrophobic function of the hydrophobic channel is completely lost, so that the waterproof effect and durability of the whole underground structure are affected. Disclosure of utility model The utility model aims to provide a basement ground drainage structure which can more effectively prevent and treat the problems of water seepage, moisture regain and the like on the basement ground, further improve the use environment of the basement and improve the overall quality and durability of a building. The utility model is realized by the following technical scheme: a basement ground drainage structure comprising: The basement comprises a basement bottom plate layer, wherein a hydrophobic groove is formed in the upper surface of the basement bottom plate layer; The basement floor layer covers the drainage grooves and the area, on which the drainage grooves are not formed, of the upper surface of the basement floor layer; A hydrophobic channel disposed within the hydrophobic recess, the hydrophobic channel comprising: hydrophobic pipe and And the water guide filling layer is filled in the hydrophobic groove and positioned around the hydrophobic pipe. Optionally, the hydrophobic tube is made of a non-metallic material or made of a corrosion resistant metallic material; the water-permeable pipe is provided with penetrating water-permeable holes. Optionally, the hydrophobic channel further comprises a water permeable filtering layer wrapped on the periphery of the hydrophobic pipe.
