塑料盲溝

產品介紹

塑料盲溝是由塑料芯體外包裹濾布組式。塑料芯體是以熱可塑性合成樹脂為主要原料,經過改性,在熱熔狀態下,通過噴咀擠壓出細的塑料絲條,通過成型裝置擠出的塑料絲在結點上熔接,形成三維立體網狀結構。塑料芯體有矩形、中空矩陣、圓形中空圓形等多種結構形势。該原料战胜了傳統盲溝的缺點,具有表面開孔率高,集水性好,空闲率大,排水性好,抗壓性強,耐壓性好,柔性好,適應土體變形,耐久性好,重量輕,施工便当,工人勞動強度大大下降,施工效率高,是以受到工程局的普遍歡迎,并得到廣泛的應用。

產品用途

公路、鐵路路基路肩的加固排水;隧道、地鐵地下通道、地下貨場的排水;山坡地、邊坡開發的水土保持;各種擋土墻垂直及程度排水;蹦滑地、火力電廠灰堆、垃圾填埋工程排水;運動場、高爾夫球場、棒球場、足球場、公園、屋頂花園、花臺等安息綠地的排水;建筑基礎工程施工排水;農業、園藝地下灌溉、低洼潮濕的的排水系統;整地工程的排水。

Plastic Blind Ditch

Product Introduction

Plastic blind ditch is a type of filter cloth wrapped by a plastic core. The plastic core is made of thermoplastic synthetic resin as the main raw material. After being modified, in the hot-melt state, a thin plastic wire is extruded through a nozzle, and the extruded plastic wire is welded at the node by a molding device to form a three-dimensional three-dimensional network structure. The plastic core has various structural forms such as a rectangle, a hollow matrix, and a circular hollow circle. This material overcomes the shortcomings of traditional blind trenches, has high surface open porosity, good water collection, large porosity, good drainage, strong pressure resistance, good pressure resistance, good flexibility, adapt to soil deformation, good durability , Light weight, convenient construction, workers' labor intensity is greatly reduced, and construction efficiency is high, so it is generally welcomed by the Engineering Bureau and has been widely used.


Product Application

The products are mainly used for the drainage reinforcement of highway and railway subgrade shoulders; drainage for tunnels, subway underground passages and underground freight yards; soil and water conservation for hillside and slope development; vertical and horizontal drainage along various retaining walls; slippery ground and firepower Drainage of power plant ash piles and waste landfill projects; drainage of resting green spaces such as sports fields, golf courses, baseball fields, football fields, parks, roof gardens, flower terraces and etc; drainage of construction works for infrastructure projects; drainage of agricultural, horticultural underground irrigation, and low-lying wetlands System; drainage of site preparation works.

盲溝指的是在路基或地基內設置的充填碎、礫石等粗粒质料并鋪以倒濾層(有的其中埋設 透水管 )的排水、截水暗溝。盲溝叫暗溝,是一種地下排水渠道,用以排除地下水,降低地下水位。

盲溝設計

當頂進橋涵及部分引道位于地下水位以下,且引道為分離式結構時,地下水會從接縫中滲出,故需采用經常性的排水步骤,如頂進橋涵的底板埋入大地以下不深時,需降低的地下水位幅度小,且多為淺層水,出水量一般不大,采用盲溝排水的想法,滿足要求,這種办法因具有結構簡單,施工便利,降水均勻等優點而被廣泛选取。盲溝設計一般不作計算,選用Φ=30cm滲水管,埋設于濾水層。在出格情況下,如遇含水量較豐富的地層,滲透系數很大時,需進行現場抽水試驗,以確定其涌水量,或根據水文地質資料,用井點降水法計算地下水量,根據盲溝的坡度與管內流速來選擇管徑。
