Jul 1, 2010 - KK Introduces Innovative Manhole Covers

In our 25 years experience of making precast concrete manhole covers and frames, we have realized that the current IS code has failed to meet some of the primary functions for which it was designed.

The IS code for Heavy Duty covers provides for 2mm thick mild steel sheet around the periphery of the cover and two mild steel lifting hooks placed about 2 to 3 inches away from the extreme edge of the cover. It also provides for a gap of 5mm around the cover between the cover and the frame besides a test load of 20 MT for failure.

All the above specifications except the test load have miserably failed to provide a cover which can be opened and closed as and when required, due to the following reasons explained. First, rusting and subsequent swelling of the mild steel rim compresses and hardens the dust collected in the 5mm gap between the cover and frame. This makes it practically impossible to remove the cover from the frame. Second, the hooks are so positioned that the workman who is trying to remove the cover by usually available tool, i.e pickaxe, gets no leverage. In this process, sometimes the workman pulls out the hook from the cover. Common sense would dictate that the fulcrum should be obtained from an object away from the object the workman is trying to lift. Third, the m.s. hooks corrode with time and ultimately fail.

Recognizing these issues, we have modified the design of the manhole cover in three areas:
  • The metal strip around the cover has been deleted, since it was not to remain for a long time anyway
  • Position of the lifting hooks has been shifted to the extreme edges of the cover so that when using a pickaxe to move the cover, the frame edge automatically becomes the fulcrum
  • The mild steel hooks have been HOT DIP GALVANISED to prevent rusting of hooks for a long time to come

The ultimate result of these improvements is a product that is user friendly and low maintenance.
 
Dec 1, 2009 - KK launches for the first time in India Precast Reinforced Concrete Light Poles.

KK introduces architectural light poles in precast reinforced concrete meant for gardens, recreational areas, parking lots, and industrial lighting. These light poles are a cost-effective substitute to traditional steel light poles. Moreover, precast concrete light poles have longer life as they are not susceptible to corrosion as steel light poles are. Currently, light poles are available in octagonal cross-section with a mounting height ranging from 11.5 to 15 feet. The light pole can be directly embedded in ground or bolted on to a concrete foundation. The light pole incorporates a conduit running along the length of the light pole and a recessed hand hole for cable entrance and fuse. The light pole also incorporates a steel pipe at the top to which the light fixture can be attached.
 
Nov 1, 2009 - KK launches an innovative solution to urban tree problem

We all love trees for their beauty and their ability to keep the environment clean yet trees are the most neglected entities on the urban Indian roads now days. The urban Indian road infrastructure has not adequately planned for cohabitation of trees, human beings, and vehicles. We are running out of space and the easy solution is to encroach upon the space occupied by the silent spectators, i.e., trees. We are sure that each one of us has witnessed a tree on the road side that just does not have the breathing room to grow because the area around the trees has been concreted to the extent that water cannot reach its roots. This situation is just not sustainable and some things going to give if something is not done.

To address this major problem, KK has developed a precast concrete tree surround that is cost effective, durable, theft-proof, and elegant. This innovative tree-surround incorporates holes to allow water to reach the tree roots and is suitable for trees up to a diameter of 450 mm (18 inches). The tree surround is assembled from 4 identical components. The top surface of the tree surround has been ground to a smooth finish to add to the beauty of the road infrastructure.
