Grouting soil retaining steel plate for steel pipe pile retaining wall
The groutable soil retaining steel plate comprises a steel soil retaining plate, a water outlet valve is arranged above the steel soil retaining plate, a grouting opening is formed in the bottom of the steel soil retaining plate, and a geotechnical cloth fixing steel sheet is arranged on the back face of the steel soil retaining plate. Compared with the prior art, the water outlet valve and the geotechnical cloth on the back of the water outlet valve are arranged, so that part of sandy soil is actively isolated, underground water is led out, the water pressure is reduced, and the steel soil retaining plate is conveniently and rapidly welded and fixed; a grouting opening is reserved in the steel soil retaining plate, chemical grouting behind the soil retaining plate can be actively carried out by connecting a grouting machine, stabilization of sandy soil behind the soil retaining plate is accelerated, and water and soil loss is reduced as much as possible; compared with a common soil retaining plate, in the aspect of cost, only the cost of the water outlet valve, the geotechnical cloth and the geotechnical cloth fixing steel sheet is increased, and the cost is remarkably saved.
本发明公开了一种钢管桩挡土墙用可灌浆挡土钢板，包括钢制挡土板，所述钢制挡土板上方设有出水阀门，所述钢制挡土板底部设有灌浆口，所述钢制挡土板背面设有土工布固定钢片，所述钢制挡土板背面与土工布固定钢片之间穿设有土工布，本发明与现有技术相比的优点在于：本发明通过设置出水阀和背后的土工布，主动隔绝了部分砂土并将地下水引出，降低水压，便于迅速烧焊固定钢制挡土板；钢制挡土板预留了灌浆口，可以通过连接灌浆机，主动进行挡土板后的化学灌浆，加速稳定背后的砂土，尽可能减少水土流失；本发明相较普通挡土板，成本方面仅增加了出水阀门、土工布和土工布固定钢片的成本，成本节约显著。
