Description
本考案は、施工防護の技術分野に属し、より具体的には、特に掘削工事における溢れ出し泥の汚染率を低減する漏れ防止装置に関する。 TECHNICAL FIELD The present invention belongs to the technical field of construction protection, and more specifically relates to a leak prevention device for reducing the contamination rate of spilled mud, especially in excavation construction.
地下工事の囲い構造は、孔形成中に泥擁壁を使用する必要があり、施工中、地下水の浸入、掘削スラグの混入及び建設機械の影響、及びコンクリート打設中のコンクリートのリフトアップ作用により、孔中の擁壁泥が非常に簡単に孔から溢れ出して、施工現場の汚染を引き起こして、その汚染面積が大きくて、清掃が困難であり、施工現場の文明施工レベルを大幅に下げると同時に、大量の人力で清掃する必要がある。大量の人力と物資を浪費し、現場の工事に大きな影響を与え、研究によると、掘削杭１本あたりの泥が流れる範囲の平均値は１９．５ｍ２で、掘削面積の１２．６８倍で、汚染面積が大きく、泥の流出問題を処理するために、１本の引き抜き抵抗杭を施工するごとに平均１６．０時間をかけて清掃する必要があり、清掃に時間がかかり、このことから、孔形成の泥の流出汚染の特徴は主に「汚染面積が大きい」と「清掃に時間がかかる」であることがわかる。 The fencing structure of underground construction requires the use of mud retaining walls during hole formation. , the retaining wall mud in the hole is very easy to spill out of the hole, causing pollution of the construction site. At the same time, it is necessary to clean with a large amount of human power. It wastes a large amount of manpower and materials, and has a great impact on the site construction. According to research, the average mud flow area per excavation pile is 19.5m2 , which is 12.68 times the excavation area. , the polluted area is large, and it takes an average of 16.0 hours to clean each pull-out resistance pile construction to deal with the problem of mud runoff, which takes a long time to clean. , it can be seen that the characteristics of pore-forming mud runoff pollution are mainly ``large contaminated area'' and ``long cleaning''.
そのため、孔形成溝形成中の泥の流出を減らし、孔形成溝形成中の施工現場の文明施工レベルを高め、文明施工資源の消費を減らし、施工コストを節約するための新しい装置を研究する必要がある。 Therefore, it is necessary to research new equipment to reduce the outflow of mud during the formation of trenches, improve the civilized construction level of the construction site during trench formation, reduce the consumption of civilized construction resources, and save construction costs.
