自嵌式植生擋土墻砌塊塑料模具，指的是依靠墻身自重抵抗土體側(cè)壓力的擋土墻。重力式擋土墻可用塊石、片石、混凝土預(yù)制塊作為砌體，或采用片石混凝土、混凝土進(jìn)行整體澆筑。半重力式擋土墻可采用混凝土或少筋混凝土澆筑。重力式擋土墻可用石砌或混凝土建成，一般都做成簡(jiǎn)單的梯形。它的優(yōu)點(diǎn)是就地取材，施工方便，經(jīng)濟(jì)效果好。所以，重力式擋土墻在我國(guó)鐵路、公路、水利、港灣、礦山等工程中得到廣泛的應(yīng)用。The block plastic mold of self embedded vegetation retaining wall refers to the retaining wall that relies on the self weight of the wall to resist the lateral pressure of the soil. For gravity retaining wall, block stone, rubble and precast concrete blocks can be used as masonry, or rubble concrete and concrete can be used for overall pouring. Semi gravity retaining wall can be poured with concrete or less reinforced concrete. Gravity retaining walls can be built of stone or concrete, usually made of simple trapezoid. It has the advantages of local materials, convenient construction and good economic effect. Therefore, gravity retaining wall is widely used in railway, highway, water conservancy, harbor, mine and other projects in China.
