Self-adaptive high-water-level change reservoir area bridge concrete pumping device and construction method

Abstract

The invention provides a self-adaptive high-water-level change reservoir area bridge concrete pumping device and a construction method.The self-adaptive high-water-level change reservoir area bridge concrete pumping device comprises a pump pipe assembly arranged on a buoy unit, the pump pipe assembly comprises a first pipe body, the upper portion of the first pipe body is fixedly arranged on a pier column, a horn mouth is formed in the lower portion of the first pipe body, and the first pipe body is sleeved with a second pipe body; the bottom of the second pipe body is connected with a fourth pipe body through a third pipe body, a fixing unit is arranged at the top of the second pipe body, the first pipe body is arranged in the fixing unit in a penetrating mode, a rolling device is fixedly arranged on the inner side of the second pipe body, a self-adjusting locking mechanism is arranged on the lower side of the rolling device, and the fixing unit is used for fixing the second pipe body. The rolling device and the self-adjusting locking mechanism are respectively used for limiting and locking the second pipe body. The structure is ingenious, the construction efficiency can be greatly improved, the pump pipe can adapt to water level changes and be adjusted, it is guaranteed that the self-state is stable and locked, operation is easy, and use is safe and convenient.

Description

technical field [0001] The invention relates to the technical field of pontoon concrete pumping, in particular to a bridge concrete pumping device and a construction method for self-adaptive high water level fluctuation reservoir area. Background technique [0002] For the concrete construction of bridges in reservoir areas with high water level fluctuations, steel trestle bridges are generally built on existing fixed platforms, and the construction needs to be designed and constructed according to the highest water level. The erection process of fixed platforms is cumbersome, the construction period is long, and the investment in labor, materials and equipment is relatively high. The longer the free length of the pile in the deep water area, the worse the stability, and the fixed platform is easily unstable when subjected to external force loads. In the construction of bridge piers, concrete is usually transported to the pouring position by a concrete pump through a pump pi...

Problems solved by technology

[0003] The invention provides a bridge concrete pumping device and construction method for self-adaptive high water level variable reservoir area, which solves the problem that the pump pipe cannot adapt to the water level change and cannot be adjusted in time, resulting in uneven stress and damage, long construction period, low efficiency, and poor construction efficiency. The cost is high, and it cannot guarantee the stability and locking of its own state during the change of water level
