Cloth bags, also known as geotextile pipes, mortar-type geotextile bags. Mortar-type geotextile bags are large areas of continuous bag-like material composed of two layers of geotextile fabric, bag filling cement mortar, formed concrete slab after solidification as a whole, it can be used as slope protection. With a length of nylon rope to keep it between two layers of bag space, you can control the thickness of the filling. Pouring in the field with a high-pressure pump. Mortar injection mold bag, the excess water can drain away from the fabric pores, therefore reducing the moisture, accelerate the solidification rate, the strength increased. Press molding process can be divided into bags Woven Bag and ease of bag types. Woven Bag Have their point drainage and filling after forming into the shape of a filter point (FP type), thin, non-filtered point (NF type), thick No filter point (CX type), hinged (RB type ), frame type (NB-type) and other species.
Mold bag laying
Mold bag by the manufacturers after processing is good, transported to the installation site patchwork, two adjacent mold bag seams, laid nonwoven geotextile, geotextile and geotextile bags lap length is 50cm. On mold bag, insert the lower edge Guadai steel truss filling spout, move to the slope. While the dike set anchor (steel piles), spacing 1 ~ 1.5m, 0.5t manual hoist hang on each anchor; the upper edge of bag attached to 0.5t manual hoist, and from upstream to downstream slope towards laying down the slope, the lower edge of the same steel pipe pile fixed.
Mortar-type geotextile bagged Slope conservation
After filling mortar After 45 minutes of bag surface leakage pulp washing. After the final setting of mortar began sprinkler maintenance required slope surface in a wet state during curing, curing time of 7 days.
Mortar mold bag filling process and should pay attention to the main problems
(1) In order to prevent clogging of the accident, you should always check the grading and mortar slump; prevent filling failure, requiring maximum aggregate size no larger than 1/3 the diameter of the tube pumping, pumping pressure filling, not less than 200Kpa, pumping distance should not exceed 50m; prevent the pump into the air, causing plugging or gas explosion; filling should be continuous downtime normally exceed 20min.
(2) should feel free to contact between the pump and filling operations staff, in close cooperation. To prevent the emergence of packing thickness at its base portion and the filling spout significantly uneven. It should be noted pouring to filling spout and flush the pump stops 3 ~ 5min, sound of rain water to be pumped again. Promptly shut down after filling in place; the event bulging, should be shut down, find the cause and treatment.
(3) passage of bag between the blocks must be someone responsible for crushes to make cement mortar passed.
(4) Always check whether the top of the hill steel piles securely fastened to avoid the process of filling the mold Bag decline.
Sisiyuan cloth bags Products
Sisiyuan cloth bags are wear-resistant, corrosion-resistant, UV resistant, flame retardant, antistatic properties, its unique high-quality, high efficiency its popularity. Dam cloth bags made film bags as a new building materials, can be widely used in rivers and lakes slope revetment harbor, docks and other protection works.
Sisiyuan cloth bags made of bag Features
(1) construction molding using a sprinkler, the construction is simple and fast.
(2) to adapt to a variety of complex terrain, especially in deep water revetment, cofferdam bottom protection do not require a direct underwater construction, high degree of mechanization, the slope large surface area, strong integrity, good stability, long life.
(3) has a certain permeability, after the concrete or mortar poured into excess water seeping through the fabric gap, can quickly reduce the water-cement ratio, the concrete to accelerate the solidification rate, increase the compressive strength of the concrete.
Sisiyuan Conclusion
Cloth bags through scientific design, in order to effectively control costs, reduce costs and to maximize the economic benefits of the fight. The mortar-type geotextile bagged program saves about 20% of the project cost more than riprap revetment construction program. We believe mortar type geotextile bags embankment slope in its future renovation works has been widely used.
