Embodiment Construction

[0017] refer to figure 1 , the present invention is a kind of concrete pouring construction method, is characterized in that, comprises the following steps:

[0018] 1) Pour a section of underwater concrete in the concrete pouring slot;

[0019] 2) Detecting the excess of the mud index on the rising surface of the underwater concrete;

[0020] 3) Use the slag extraction pipe to extract the slag at a distance of 1-2m from the underwater concrete surface, and at the same time replenish the grout, and then continue to pour the underwater concrete;

[0021] 4) Lift the slag extraction pipe so that the slag extraction pipe is always located at 1-2m above the gradually rising underwater concrete surface until the concrete is poured.

[0022] The concrete pouring construction device implementing the above method includes a plurality of concrete conduits 1 that extend into the underwater concrete at one end of the pouring slot, the top of each concrete conduit 1 is provided with a f...

Abstract

The invention discloses a concrete grouting construction method and a device for implementing the same. The device comprise a plurality of tremies of which one ends extend into underwater concrete in a grouting slot; a blanking hopper is arranged at the top end of each tremie; a slag pumping pipe is arranged in the grouting slot; and the bottom end of the slag pumping pipe is positioned at a position which is 1-2 meters away from the surface of the underwater concrete. According to the concrete grouting construction method and the construction device, slurry above the surface of the underwater concrete is pumped through the slag pumping pipe in a concrete pouring process, and concrete is poured in the pumping process, so that the quality of underwater concrete is prevented from being damaged by the slurry above the surface of the underwater concrete, and the piling quality of the underwater concrete is effectively ensured; and the method and the device can be applied to the field of building construction.

Description

technical field [0001] The invention relates to the field of building construction, in particular to a concrete pouring construction method and a device for implementing the method. Background technique [0002] Generally, after the hole is formed in the pile body or the underground diaphragm wall, the underwater concrete will be poured after clearing the hole. Pile quality defects. Contents of the invention [0003] In order to solve the above problems, the present invention provides a concrete pouring construction method that can effectively guarantee the quality of pile formation and a device for implementing the method. [0004] The technical solution adopted by the present invention to solve its technical problems is: [0005] Concrete pouring construction method, is characterized in that, comprises the following steps: [0006] 1) Pour a section of underwater concrete in the concrete pouring slot; [0007] 2) Detecting the excess of the mud index on the rising su...
