Frame type combined dam

Abstract

This is a frame assembly of dikes and dams use to waterpower, navigation, and dredge the waterways in the river of seaport. It contains: The piles are not less than two arrangements of piles, on the pile's top install an interface for to connect with the prefabricated plates. The protective prefabricated plates inlay with successively pile's trough successively, two ends of the beams are connected with the neighboring different range of piles, the best form of the pile's bottom is wedge form, the best form of prefabricated plate on the lowest layer is wedge form too, and the section form of prefabricated plate may be square or T form.

Description

technical field [0001] The invention relates to a dam used in water conservancy and shipping engineering for the treatment of river beds and estuaries, in particular to a frame-type combined dam. Background technique [0002] At present, the traditional dams and dams used in water conservancy and shipping engineering in the treatment of riverbeds and estuaries to the sea are structures with upright or slope embedded stones or concrete face protection and riprap foundation protection. The dam has the following disadvantages: 1) It is large in size and high in cost; 2) It is prone to leakage and piping; 3) It needs to build a cofferdam during construction; 4) It is inconvenient for reinforcement and maintenance; 5) It cannot effectively eliminate temperature expansion , internal stress such as dry and wet expansion of sediment, uneven foundation settlement, and external stress such as effectively resisting earthquake aftermath, the strain capacity is not strong; 6) The full li...

Problems solved by technology

The dam has the following disadvantages: 1) It is large in size and high in cost; 2) It is prone to leakage and piping; 3) It needs to build a cofferdam during construction; 4) It is inconvenient for reinforcement and maintenance; 5) It cannot effectively eliminate temperature expansion , internal stress such as dry and wet expansion of sediment, uneven foundation settlement, and external stress such as effectively resisting earthquake aftermath, the strain capacity is not strong; 6) The full line of deep-water wharves cannot be realized at the side of the dam; 7) The dam cannot withstand river water and sea water for a long time during construction The construction conditions are harsh; 8) Mechanized construction cannot be fully implemented, and only layer-by-layer reinforcement and heightening are possible, with slow construction speed and high labor intensity; The lengthening is limited, especially when the river bed has been washed to a certain depth, it is very difficult to deepen the foundation of the embankment; 10) The climbing height of the tidal surge cannot be effectively forced down, and the tidal level cannot be suppressed

[0003] The combined retaining embankment disclosed in Chinese patent 99219030.4, although it has realized the use of standard components and mechanized construction and assembly, compared with embankments built with soil or woven bags filled with soil, the construction speed has been improved and the labor intensity has been reduced, but its structure is relatively complicated. , and once its height is determined, it is difficult to increase it, so it cannot withstand big tides and waves, but can only be a temporary building used on a small scale
