Description
- This application is a continuation-in-part application of the utility patent application (Ser. No. 11/036,633) filed on Jan. 13, 2005.
- 1. Field of the Invention
- This invention relates to devices that can act as ground cover hold downs or water runoff barriers, and more particularly to such devices that are filled with water and used on flat and sloped surfaces.
- 2. Description of the Related Art
- Recently, wind and water erosion control have become important issues in the construction industry. Many municipalities have promulgated regulations or ordinances that require construction companies to cover excavated dirt placed in a pile more than 72 hours with a sheet-like ground cover. Such ground covers are spread out over the pile and then typically held down by sandbags, stakes and ropes. Many municipalities have also promulgated regulations or ordinance that requires contractors to control the flow of rain water and flooding around and from the construction site. As a result, construction companies spend considerable amount of time filling and placing sand bags at different locations over ground covers and around the construction site to control rain water runoff and flooding. When the dirt pile is removed or when the construction site is being cleaned, considerable amount of time is spent picking up and emptying the sandbags and removing excess sand from the construction site.
- What is needed is a device that can be easily and quickly setup and used as a hold down device for a ground cover or used as a dam or barrier to control runoff rain water at or around a construction site. What is also needed is such a device that can be stored in a compact configuration and then setup by filling the device with water that acts as an expander and as a weight. What is needed is such a device where its shape can be easily manipulated or altered and then fixed in alternative shapes to direct runoff rain water in different desired directions. What is also needed is such a device that enables the water to be easily drained from the device so that the device may be returned to its compact configuration for storage.
- The above stated needs are met by the elongated hold down device and adjustable barrier disclosed herein that comprises a flexible, elongated bladder capable of being rolled or folded into a compact configuration for storage and then unrolled or unfolded into an extended configuration when used. The bladder is made of water tight material intended to be filled with water. Formed on one end of the bladder is at least one filling port with a removable cap or plug attached thereto that allows the user to selectively fill the bladder with the water. Formed on the opposite end of the bladder is a drain port with a cap, plug or two way valve. The bladder is made of a sufficient flexible material so it may be bent to form a straight or curved elongated weight or folded over to shorten and adjust its overall length. Stakes are used to hold the bladder when filled with water in its desired shape and length and in a fixed position over the ground.
- As stated above, the bladder may be used as a hold down device or as a rain water runoff barrier. In some situations, it may be used for both purposes. Initially, the bladder is unfolded and placed in a flat configuration over a surface to be protected with the filling and drain ports facing upward and the eyelets on the opposite longitudinal edges extending laterally. The bladder may be aligned in a straight or a curved configuration. The bladder may also be folded under at any position to shorten its overall length.
- Once the general layout of the bladder is established, the filling port is opened and the drain port is closed and the stakes are then selected and inserted through the eyelets. Normally, the stakes are partially imbedded into the ground to loosely hold the bladder in place as water is added to the bladder. As water is added to the bladder, the bladder slowly expands from a flat configuration into a tubular configuration that is oval in a cross-sectional configuration. Because the stakes are only partially embedded into the ground, the eyelets are able to slide upward over the stakes as the bladder expands. When the bladder has been filled with the desired volume of water, the filling port is closed and the stakes are further driven downward through the eyelets to securely hold the bladder in place.
- To remove the device, the drain plug is opened so that the water may flow through the bladder. When a two way valve is attached to the drain port, an air pressure line may be attached to the valve to deliver air to the bladder to force the water in the bladder back through the filling port and into a storage tank.

FIG. 10 is a sectional side elevational view of two devices longitudinally aligned and connected together with a connection hose. - Referring to the FIGS, there is shown a ground hold down
device 10 herein that comprises a flexibleelongated bladder 12 capable of being rolled into a compact roll for storage and then unrolled into an extended configuration for use. Thedevice 10 is designed to be used as an elongated weight to hold down aground cover 90 or as a dam or barrier for controllingrain water runoff 92. - The
device 10 includes anelongated bladder 12 made of durable, flexible, water-proof material designed to be used outdoors in a wide range of hot and cold climate conditions. In the preferred embodiment, thebladder 12 is rectangular, approximately 10 to 32 feet in length and 6 to 12 inches in width. When thebladder 12 is filled withwater 80, thebladder 12 is cylindrical and oval in cross-section as shown inFIGS. 4 and 6 . In the preferred embodiment, thebladder 12 is made of a single panel 14, which is the twolongitudinal edges end edges bladder 12 and adhesively or radio frequency welded together so that thebladder 12 forms a water-tight structure. - Evenly spaced apart and formed on the two opposite
longitudinal edges bladder 12 are reinforced, lateral extendingeyelets 25. In the preferred embodiment, eacheyelet 25 includes asemi-circular body 26 perpendicularly aligned on aflexible base 27 adhesively or welded to theoutside surface 13A of thebladder 12. Thesemi-circular body 26 is centrally aligned with the bladder'smidline axis 23 and astake hole 30 is formed therein that is perpendicularly aligned with the bladder's lateral,midline axis 23. Theflexible base 27 is sufficiently flexible and rigid so that thebladder 12 when filled withwater 80 expands into an oval cross-section configuration. In the preferred embodiment, theeyelets 25 are spaced apart on the opposite edges 24 to 48 inches. - Located on one end of the
bladder 12 is afilling port 35 with aremovable cap 40. In the preferred embodiment, thefilling port 35 includes aneck 36 withexternal threads 37 formed thereon that interconnect withinternal threads 42 on aremovable cap 40. Thethreads neck 36 is made of PVC and is adhesively or welded to theinside surface 13B of thebladder 12. Theneck 36 has an inside diameter of approximately 1 inch so that when the end of a standard ½ or ⅝ inch garden hose inserted into theneck 36, a gap is created that allows air to escape from thebladder 12 when being filled with water. - Attached to the opposite end of the
bladder 12 is adrain port 50. Thedrain port 50 may be identical to the fillingport 40 as shown inFIG. 4 or it may be a flush mounted structure as shown inFIG. 7 with an inward extendingneck 52 with a central threaded bore 51 as shown inFIG. 7 . Theneck 52 is attached to aflange 54 that is adhesively or welded to theinside surface 13B of thebladder 12. A T-shaped threadedplug 55 with a threadedneck 56 or a two-way ball valve 60 with a threadedneck 62 may be attached to the threaded bore 51. - An
optional tether line 68 may used between the connect and theplug 55 to thedrain port 50. - As mentioned above, the
bladder 12 is designed to be stored in a flat, compact rolled, configuration when not in use. When thebladder 12 is used, it is aligned in a straight or curved configuration over theground cover 90 so that the fillingport 40 and drainport 50 face upward. Thebladder 12 is aligned so that the fillingport 40 is positioned at a higher elevation than thedrain port 50 so thatwater 80 when poured into the fillingport 40 flows downhill and fills thebladder 12. Theeyelets 25 on each side of thebladder 12 extend laterally. -
Stakes 70 are then selected and inserted through eacheyelet 25 and partially forced through theground cover 90 and into theground surface 100. Aswater 80 is added to thebladder 12, theeyelets 25 on each side of thebladder 12 are forced upward as thebladder 12 becomes oval in the cross section. To accommodate this expansion, thestakes 70 are only partially driven into the soil so that theeyelet 25 may slide upward over thestake 70 during the filling process. Once filled, the worker can then force eachstake 70 downward througheyelet 25 to tightly hold thebladder 12 over theground cover 95. On steep slopes,water 80 may be added to thebladder 12 when it is in a partial rolled configuration. Aswater 80 is added to thebladder 12, thebladder 12 automatically unravels itself over the slope as shown inFIG. 8 . The worker then insertsstakes 70 into eacheyelet 25 and drives them through theground cover 95 and into theground surface 100. - As mentioned above, the
device 10 may be used as a dam or barrier. For such use, thebladder 12 is oriented in a flat configuration and then bent or curved in a desired configuration to deflect rain water runoff as shown inFIG. 2 . Thestakes 70 are then selected and then inserted to eacheyelet 25.Water 80 is then dispensed through the fillingport 35. The amount of bending of thebladder 12 must be limited so thatwater 80 may flow through the area that is narrowed and restricted. Thestakes 70 may be forced completely into the ground so thatbladder 12 remains in a bent or curved shape when filled. - On a sloped ground surface where
water 80 from thebladder 12 may be desirable or permitted, theplug 55 may be manually removed from the drain port 45 to allow thewater 80 from thebladder 12 to flow directly onto theground cover 90 or onto the surroundingground surface 100 or drainage system. On a watersensitive ground surface 100, a twoway ball valve 60 as shown inFIG. 7 , may be used that connects to apressurized air line 89 that forces thewater 80 from thebladder 12 through the fillingport 35 to a storage tank (not shown). Also, thedevice 12 may be sold as a kit with ashort connection hose 100 with threaded connectors 102, 102′ at its opposite ends that connects to the fillingport 35 and drainport 40 on adjacent longitudinally alignedbladders - The
bladder 12 is cylindrical in the cross-section and designed to hold approximately 1 gallon ofwater 80 per 12 inches of length. When filled withwater 80, thebladder 12 is approximately 7 inches in width and 6 inches in height. In the preferred embodiment, thebladder 12 is made from a PVC coated polyester woven sheet with a weight between 18 to 42 oz. per square yard. Such material is also U.V. resistant and withstands temperatures between minus 40 degrees F. and plus 180 degrees F. When thebladder 12 is filled withwater 80, thebladder 12 weighs approximately 8 lbs per 12 inches in length which is an optimum amount of tensile force applied to a ground cover on a 20 degree sloped ground surface for holding a 30% grade. It should be understood, that the size of the bladder, number of the eyelets and the spacing on the bladder determines the slope recommended slope grade. - In compliance with the statute, the invention described herein has been described in language more or less specific as to structural features. It should be understood, however, that the invention is not limited to the specific features shown, since the means and construction shown is comprised only of the preferred embodiments for putting the invention into effect. The invention is therefore claimed in any of its forms or modifications within the legitimate and valid scope of the amended claims, appropriately interpreted in accordance with the doctrine of equivalents.
