A sensor system for a buried waste containment site having a bottom wall barrier and sidewall barriers, for containing hazardous waste. The sensor system includes one or more sensor devices disposed in one or more of the barriers for detecting a physical parameter either of the barrier itself or of the physical condition of the surrounding soils and buried waste, and for producing a signal representing the physical parameter detected. Also included is a signal processor for receiving signals produced by the sensor device and for developing information identifying the physical parameter detected, either for sounding an alarm, displaying a graphic representation of a physical parameter detected on a viewing screen and/or a hard copy printout. The sensor devices may be deployed in or adjacent the barriers at the same time the barriers are deployed and may be adapted to detect strain or cracking in the barriers, leakage of radiation through the barriers, the presence and leaking through the barriers of volatile organic compounds, or similar physical conditions.

A connector for a piece of glass, the connector comprising: a main post having a bottom hole defined in one end of the main post to adapt to a hinge of the piece of glass sheet, a side hole defined in a periphery of the main post, a top hole defined in another end of the main post to threadingly receive therein a bolt; at least one secondary post having a connecting end inserted into and secured in the side hole by the bolt, the at least one secondary post provided with a plan face formed on a periphery of the secondary post to be engaged with the bolt and at least one securing unit secured on the periphery of the secondary post, each securing unit including a first connector attached to the periphery of the secondary post, a second connector and a securing bolt, wherein the securing bolt extends through the second and first connector so as to threadingly engage with a threaded hole in the periphery of the secondary post and the piece of glass is secured between the first and second connector. 2. The connector as claimed in claim 1, wherein the secondary post has two securing units formed on one side of the periphery of the secondary post. 3. The connector as claimed in claim 1, wherein the secondary post has two pairs of securing units each pair formed on one side of the periphery of the secondary post and corresponding to the other pair of securing unit. 4. The connector as claimed in claim 1, wherein the main post has two secondary posts each extending in opposite direction and having at least one securing unit formed on the periphery of the secondary post. 5. The connector as claimed in claim 2, wherein the main post has two secondary posts each extending in opposite direction and having at least one securing unit formed on the periphery of the secondary post. 6. The connector as claimed in claim 3, wherein the main post has two secondary posts each extending in opposite direction and having at least one securing unit formed on the periphery of the secondary post. 7. The connector as claimed in claim 1, wherein the main post has an auxiliary seat received in the top hole and provided with a flange, truncated conical bottom formed on one side of the flange and a channel defined to communicate with the top hole so that the main post is able to be adapted to secure with the hinge of the piece of glass. 8. The connector as claimed in claim 2, wherein the main post has an auxiliary seat received in the top hole and provided with a flange, truncated conical bottom formed on one side of the flange and a channel defined to communicate with the top hole so that the main post is able to be adapted to secure with the hinge of the piece of glass. 9. The connector as claimed in claim 3, wherein the main post has an auxiliary seat received in the top hole and provided with a flange, truncated conical bottom formed on one side of the flange and a channel defined to communicate with the top hole so that the main post is able to be adapted to secure with the hinge of the piece of glass. 10. The connector as claimed in claim 4, wherein the main post has an auxiliary seat received in the top hole and provided with a flange, truncated conical bottom formed on one side of the flange and a channel defined to communicate with the top hole so that the main post is able to be adapted to secure with the hinge of the piece of glass. 11. The connector as claimed in claim 5, wherein the main post has an auxiliary seat received in the top hole and provided with a flange, truncated conical bottom formed on one side of the flange and a channel defined to communicate with the top hole so that the main post is able to be adapted to secure with the hinge of the piece of glass. 12. The connector as claimed in claim 6, wherein the main post has an auxiliary seat received in the top hole and provided with a flange, truncated conical bottom formed on one side of the flange and a channel defined to communicate with the top hole so that the main post is able to be adapted to secure with the hinge of the piece of glass.
