Take geotechnological tubular bag of inner core

Technical Field

The utility model relates to a geotechnique's pipe bag among the geotextile, in particular to geotechnique's pipe bag of taking inner core.

Background

In recent years, projects such as national infrastructure and environmental improvement are developed rapidly. A large amount of sludge or slurry is generated in the projects of river channel dredging, ditch and pond dredging, pile foundation hole excavation and the like. The sludge and the slurry are suspension liquid containing a certain amount of fine soil particles, have certain viscosity and can be settled in a layering way only by standing for a long time. The existing mud treatment methods mainly comprise a mud pool sedimentation air drying method, a tank car external transport to a specified place stacking method, a mechanical squeezing method and the like, and the methods have the defects of high mud treatment cost, low efficiency, easy leakage, pollution to the urban environment and the like, and bring potential safety hazards or the problems of post-land treatment and recovery and the like. The traditional slurry treatment method can not meet the requirements of modern engineering construction and environmental protection, and a high-efficiency, low-consumption and environment-friendly treatment method is urgently needed to be found. The flocculating agent is matched with the geotechnical pipe bag for filtration and dehydration, which is the development direction of rapid dehydration, solidification and decrement of sludge and slurry. However, in the process of actually using the geotextile tube bag, the dewatering effect of the geotextile tube bag is increasingly poor, so that a certain amount of slurry which has high water content and is in a flowing state (determined by the capacity of the geotextile tube bag) exists in the geotextile tube bag, the phenomenon of 'sugar core' occurs, and the slurry is difficult to dewater and solidify.

SUMMERY OF THE UTILITY MODEL

In order to solve the technical problem, the utility model provides a simple structure, economy, construction are simple and convenient, the efficient geotechnique's pipe bag of taking the inner core of dehydration.

The utility model provides a technical scheme of above-mentioned problem is: the geotextile tube bag with the inner core comprises top cloth and base cloth, wherein the top cloth and the base cloth are polygonal and have the same size and shape, the top cloth and the base cloth are sewn to form a closed tube bag, a grouting port is formed in the top cloth, and a plurality of inner cores of tubular structures or sleeve structures are arranged between the top cloth and the base cloth.

In the geotechnical pipe bag with the inner core, the inner core of the tubular structure or the sleeve structure is filled with medium coarse sand.

In the geotechnical tube bag with the inner core, the filter tube is inserted into the inner core of the tubular structure or the sleeve structure, and the filter tube is a circular tube with drain holes drilled at the periphery.

In the geotechnical tube bag with the inner core, coarse sand is filled in the inner core of the tubular structure or the sleeve-shaped structure, and the filter tubes are inserted into other inner cores and are round tubes with drain holes drilled at the peripheries.

The beneficial effects of the utility model reside in that:

1. the utility model creatively arranges a plurality of inner cores between the top cloth and the base cloth, and fills sand in part of the inner cores to form a horizontal drainage sand well; the filter pipes are inserted into part of the inner cores to form a drainage channel, so that the drainage way during slurry dehydration is increased, the drainage distance is reduced, the simultaneous drainage inside and outside the geotechnical pipe bag is realized, the slurry dehydration efficiency can be effectively improved, and the sugar core phenomenon is avoided.

2. The utility model discloses when the drainage is no longer gone out to the geotechnological tube bag, the accessible vacuum pump utilizes atmospheric pressure to pressurize the geotechnological tube bag to the filter tube evacuation, makes water discharge from the filter tube for drainage speed improves mud dehydration solidification effect.

Detailed Description

The present invention will be further described with reference to the accompanying drawings and examples.

As shown in fig. 1-6, the utility model comprises a top cloth 1, a bottom cloth 2, a plurality of inner cores 3, a filter tube 4 and medium sand or coarse sand 5. The top cloth 1 is polygonal, and a grouting connector 101 is arranged on the top cloth. The base cloth 2 is polygonal, and the size and the shape of the base cloth 2 are the same as those of the top cloth 1. The geotextile tube bag is internally provided with a plurality of inner cores 3, the inner cores 3 are arranged between the top cloth 1 and the base cloth 2, and the inner cores 3 are processed into a tubular or sleeve-shaped structure by adopting geotextile with the same top cloth base cloth.
