A simple and easy water collecting well with turnover on construction site

Abstract

This invention relates to a simple, reusable water collection well for construction sites, belonging to the field of building construction. The technical solution involves using a large-diameter corrugated pipe as the well wall, and prefabricating a grate from scrap steel bars and wooden formwork to cover the well opening. A 1.2m × 1.2m × 1.1m foundation pit is excavated at the location of the water collection well. After excavation, the bottom of the pit is leveled, and a 50mm thick C20 plain concrete subbase is poured. The corrugated pipe is a large-diameter HDPE double-wall corrugated pipe with a diameter of 800mm and a height of 1.05m, installed on the plain concrete subbase, with its upper opening aligned with the height of the temporary road in the site area. After installing the corrugated pipe, the bottom of the pipe and the concrete cushion layer are sealed with waterproof mortar; the horizontal drainage pipe in the site is connected to the side wall of the corrugated pipe in the water collection well; the foundation pit outside the corrugated pipe is backfilled with plain soil, and then concrete is poured outside the pipe, which is poured together with the temporary road in the site; the grate of the water collection well is made of scrap steel bars and formwork, and the grate is surrounded by wire mesh. The water collection well of this invention is easy to construct, standardized, and can be mass-produced to meet standardization requirements; the water collection well can be reused, and the materials used are scrap steel bars, wooden formwork, and leftover pipe ends of corrugated pipes. All structural materials are recycled from leftover materials, which is energy-saving and environmentally friendly, and meets the requirements of green construction and material saving.
