Description

Surface mats for entering equipment for promoting dehydration of dredged soft ground {OUTER LAYER STRENGTHENING MAT DEHYDRATION ADMISSION EQUIPMENT}

The present invention is designed to form a surface strengthening mat layer as a surface layer of dredged soft ground to safely and easily enter various equipment used for construction work as a surface layer of a dredged soft ground for the construction work for the improvement of dredged soft ground. In this case, the surface mat to form the surface reinforced mat layer is installed to be a surface reinforced mat layer is equipped with a reinforcement function and tensile strength to support the ground pressure of the equipment when entering the equipment to resist the behavior of the ground, In particular, the geosynthesis was made by using the most suitable geotextiles for conditions such as to ensure floating stress and proper weight.

In other words, screwed and cradle type eyelets are installed at appropriate positions so as to be maintained at an appropriate face between the upper mat and the lower mat on which the inlet is installed, and to be laid up and down. "The surface mats for equipment entry for the dehydration promotion work of dredged soil soft ground, which is formed by sewing the circumferential part stitched by the structure of the mold bite, and the inside of the upper and lower mats are formed so as to communicate with each other. It was configured to.

In use, the surface layer mat of the present invention is laid on the surface layer of dredged soft ground, and then press-filled with sand or clay, cement mortar or hard concrete through the injection hole formed in the upper mat to strengthen the surface layer. The surface strengthening mat formed as above is laid on the surface of the dredged soft ground to become a surface reinforced mat layer, and the surface layer of the dredged soft ground is strengthened, and equipment entry and construction for the dehydration promotion work of the soft ground of dredged soil is performed. It is designed to make work safe and easy.

In the surface solidification structure that is conventionally used to enter equipment required for construction work for dredged soft ground improvement, the ground is reinforced with bamboo net or civil fiber in the surface layer, and then lightweight By laying sand using equipment, the surface layer of dredged soft ground was strengthened.

In the surface solidification structure of the dredged soft ground, which has been carried out in this way, there is a cumbersome drawback that the construction speed is slow and the additional method must be performed in addition. In the structure, as a special equipment for agitation, the surface layer is solidified by mixing cement, a fastener or a special chemical solution, so that the thickness of the surface layer to be solidified becomes thick, which requires a lot of materials, and the complexity of installation and installation work. Due to the long working period, the installation and installation cost is high, and the construction speed is slowed down according to the solidification of the thickened surface layer, and the construction speed is slowed, and the curing is poor due to the salt contained in the dredged soft ground. Defects with less robustness, especially vertical drainage In the case of the construction of the vertical drain, which is a ash, the drilling of the thick surface layer to be solidified is required, which makes the drilling difficult.

In order to solve the drawbacks of the present invention, the proper face is maintained between the upper mat and the lower mat, which is made of geosynthetic fiber, and the injection hole is installed, so that the threaded eyelet or " "Bite the bite, and then sew the circumference, the surface mat of the structure that combines the upper and lower mats to communicate with each other is formed by the surface layer of the dredged soft ground by sewing the circumferential portion of the upper mat and the lower mat In the installed state, the sand is filled in the communication space portion formed while maintaining a proper space between the upper and lower mats by selecting the filling material, such as the flow of sand, soil, cement mortar or hardened concrete and pressurized and filled through the inlet It is a surface reinforcing mat filled with fillers, etc., and it is a surface reinforcing mat layer installed by laying the surface of dredged soft ground, so that it is safe and easy to enter the equipment necessary for construction work to improve dredged soft ground. Construction by simple and easy production and safe and easy equipment entry The purpose is to increase the economics by simplifying the business.
