Flexible material filling and pointing machine, and concrete deck joint method

Abstract

The invention relates to an engineering machine and an engineering method, in particular to a flexible filler inlaying machine for inlaying flexible filler into concrete panel seams of concrete face rockfill dams, as well as a concrete panel seaming method. The construction quality of flexible filler water-stopping layers of surface layers of the concrete face rockfill dams relates to dam safety and stability. Low efficiency and low quality of filler inlaying are always difficult problems perplexing engineers and technicians. The design of the invention seeks to be simple in equipment and concise in process, so as to achieve the effects of easy equipment maintenance and simple operation in practical construction, and to achieve high-speed high-quality construction. The inlaying machine is characterized in that: the inlaying machine has a machine body; a power machine is arranged inside the machine body; the power machine is connected with an extrusion screw of a filler chamber through a speed governor; the filler chamber is provided with a feed port; the machine body is provided with a traveling device; and an outlet of the filler chamber is provided with a die head and / or a mouth piece for controlling the shape of an filler extruding cross section. The concrete panel seaming method is characterized in that: filler in the filler chamber of the filler inlaying machine is heated through the extruding effect of the extrusion screw and / or through a heater; and the heated filler passes through the die head and / or the mouth piece which is arranged in the outlet of the filler chamber to control the shape of the filler extruding cross section, and then the extruded and shaped filler enters into concrete panel seams through inlaying.

Description

technical field [0001] The invention relates to engineering machinery and an engineering method, in particular to a flexible filler embedding machine for embedding flexible filler in concrete face joints of face rockfill dams and a concrete face joint method. Background technique [0002] The concrete face rockfill dam is a dam form widely used in the construction of hydropower stations at home and abroad. It uses the rockfill body as the main force-bearing structure to bear the reservoir water pressure, and the reinforcement poured from bottom to top on the facing surface of the rockfill body Concrete panels are anti-seepage structures. Due to factors such as the settlement and deformation of the dam body, the concrete panels need to be poured in blocks, so that dozens of joints are formed between the panel blocks, the plinth and the panel blocks that are integrated with the surrounding mountains. Seepage, the seepage will take away the small particles in the rockfill body...

AI Technical Summary

Problems solved by technology

At present, the embedded filling method widely used at home and abroad is artificial embedded filling. Since most of the flexible packing products sold in the domestic and foreign markets are plates or columns with rectangular cross-sections, and the packing itself has certain elastic-plastic properties, it is placed on the slope of the dam. It is very difficult to manually embed the V-shaped groove densely. When the external temperature is low and the hardness of the filler increases, the problem of embedding and filling will be more serious.

Therefore, the efficiency of artificial embedding is low and the quality of embedding is not very ideal

[0005] The patent No. ZL03266644.6 for the flexible filler extruder patent proposes a flexible filler extrusion equipment for on-site embedded filling construction, which can ensure good embedded filling compactness and interface bonding effect, and the construction efficiency is higher than that of manual embedded filling. Filling has been improved, but there are also some defects that limit its practical application in engineering. These defects are as follows:

[0006] 1. The process is cumbersome

It is necessary to drill holes on the concrete panel to install expansion bolts, and then use expansion bolts and pressure plates to fix the outer formwork; the length of the outer formwork is limited, and after one or two meters of embedding, the outer formwork and expansion bolts must be removed, moved forward and then re-fixed; Simultaneous drilling can damage the concrete surface

[0007] 2. The operation is difficult

[0008] 3. Low efficiency

Due to the need to continuously remove the mold and fix the mold, the process of inserting and filling is intermittent. The extruder will stop when it starts to fill a section of the V-shaped groove, and wait for the outer mold to be fixed again, causing the machine and operators to be idle.

[0009] To sum up, in order to solve the problems of low efficiency and poor quality of artificial embedding and at the same time eliminate the deficiencies of the prior art, the present invention proposes a flexible filler embedding machine and concrete face joint method for face rockfill dams
