Bridge pile foundation concrete pouring equipment and process applied to water accumulated area

Abstract

The invention relates to the technical field of bridge crossing construction, in particular to bridge pile foundation concrete pouring equipment and process applied to a water accumulated area. The equipment comprises a material mixing hopper, a grouting pipe and a recycling pipe; the material mixing hopper is fixedly arranged above the water surface of a foundation pit area; a stirring mechanismis arranged in the material mixing hopper; the grouting pipe is a section of vertical pipeline arranged rigidly; the top of the grouting pipe communicates with the bottom of the material mixing hopperthrough a high-pressure hose; the recycling pipe is arranged outside the grouting pipe in an nesting manner; the top of the recycling pipe is connected with the outer wall of the grouting pipe in a sealing manner; and the top of the recycling pipe communicates with the interior of the material mixing hopper through a sucking pump. The bridge pile foundation concrete pouring equipment and processapplied to the water accumulated area aim to grout concrete into a foundation pit with accumulated water from bottom to top by means of the special equipment, and perform targeted treatment on dilutedconcrete, so that the grouting difficulty of the foundation pit of the accumulated area is simplified, and meanwhile, the grouting quality is also ensured.

Description

technical field [0001] The invention relates to the technical field of span bridge construction, in particular to a bridge pile foundation concrete pouring equipment and process applied to water accumulation areas. Background technique [0002] In the traditional substructure construction of bridge pile foundations, the pouring of cast-in-place piles under water is usually done by uninterrupted pumping or floating ball method after the formation of the foundation pit. The procedure is cumbersome and time-consuming. Corresponding auxiliary measures need to be taken for the rapid formation of cast-in-place piles for underwater concrete pouring; in the construction, firstly, the concrete is not easy to be poured quickly, and uninterrupted pumping is required; secondly, when the concrete is poured continuously, it is difficult to ensure the pouring quality of the concrete , the water content of the concrete will change; the third is that the traditional concrete discharge hopper...

AI Technical Summary

Problems solved by technology

[0002]In the traditional construction of the substructure of the bridge pile foundation, the pouring piles are poured underwater. Usually, after the foundation pit is formed, the pile foundation is poured by uninterrupted water pumping or the floating ball method. The pouring of concrete requires cumbersome procedures and time-consuming construction. Corresponding auxiliary measures need to be taken for the rapid formation of concrete pouring of cast-in-place piles underwater; Second, when pouring concrete continuously, it is not easy to guarantee the pouring quality of concrete, and the water content ratio of concrete will change; third, the traditional concrete discharge hopper is a gate valve, and it is laborious to open and close the valve when filling, which is not conducive to concrete The material is discharged instantaneously, and the material discharge resistance is relatively large; and the operation process takes a long time and the work efficiency is low; it is not conducive to the construction of rapid prototyping of the concrete pouring of the substructure of the bridge pile foundation, which is mainly due to the substructure of the bridge pile foundation. The construction technology and method of concrete pouring need to be improved, and the discharge valve of the concrete hopper needs to be improved. The needs of rapid pouring and continuous pouring cannot be realized, and the quality of concrete pouring cannot be guaranteed.
