Embodiment Construction

[0016] The technical solution of the present invention will now be described in further detail in conjunction with the drawings and embodiments of the description.

[0017] The bagged plastic drainage device of the present invention comprises a plastic drainage pipe 1, a base 2 and a cloth bag 3, the outer wall of the plastic drainage pipe 1 is provided with an axial drainage groove 4, and the plastic drainage pipe 1 is provided with a connecting pipe and a drainage ditch. The drainage hole 5 of the groove, the water-permeable material 7 is filled in the drainage groove 4. The plastic drainage pipe 1 can be rolled into a tubular shape by the plastic drainage board at the construction site, and the joints can be bonded with superglue and reinforced with large staples, or can be directly molded in the factory. The base 2 is provided with a groove for snapping the plastic drain pipe 1 into it, and the function of the groove is to prevent the plastic drain pipe 1 from rotating and...

Abstract

The invention discloses a plastic drainage device which is used in soft foundation processing and composed of a plastic drainage pipe, a base and a cloth bag. The base sleeves the bottom of the plastic drainage pipe in the integral form. With the base, flatness and verticality of the plastic drainage pipe is guaranteed, and the bottom of the plastic drainage pipe is out of extrusion and damage. The cloth bag closely covers the whole device to filter soil particles. The plastic drainage pipe is used for draining for a surface channel. Pore water enters the surface channel from the surrounding and then is drained. The method that the water is drained from the inside of the plastic pipe is replaced. More importantly, the plastic drainage pipe is in the axisymmetric structure, the pressure dissipation rule of the pore water is met, allowing the pore water to enter the plastic pipe from the surrounding and achieving good drainage effect. The plastic drainage device has the advantages such as simple structure, low cost and good effect.

Description

technical field [0001] The invention belongs to the field of foundation treatment and relates to a plastic drainage device. Background technique [0002] Drainage consolidation method has been widely used as a basic theory of foundation treatment, and its representative engineering applications include vacuum preloading method and surcharge preloading method. Among them, there are two main types of vertical drainage bodies, one is sand well or bagged sand well, and the other is plastic drainage board. These two kinds of drainage bodies have their own advantages and disadvantages. The drainage around the sand well is axisymmetric drainage. The drainage is reasonable and the speed is fast, but the construction is more complicated, the construction speed is slow, and the cost is high. The plastic drainage board is simple and convenient, the construction period is short, and the cost is low. However, the plastic drainage board is a flat structure, which can only drain in one d...
