Water reducing agent injection pile for concrete

Abstract

The invention discloses a water reducing agent injection pile for concrete, and belongs to the field of water reducing agents. The water reducing agent injection pile for the concrete comprises an insertion pipe, the insertion pipe comprises a hollow pipe, the upper end and the lower end of the hollow pipe are connected with a fixing cover and a detection cover respectively, two pairs of stirring plates are fixedly connected to the outer wall of the hollow pipe, and an inner storage pipe is slidably connected into the insertion pipe; and an end cover is fixedly connected to the inner storage pipe, a pair of handles is fixedly connected to the outer wall of the end cover, a shell is fixedly connected to the end cover, an electric push rod is connected between the end cover and the fixing cover, a through hole is formed in the bottom end of the insertion pipe, a detection head is slidably connected into the through hole, and the detection head comprises a conical probe. According to the water reducing agent injection pile for the concrete, a proper dosage of water reducing agent can be injected according to the moisture content of each point of the concrete, and after the water reducing agent is injected into the concrete, the water-deficient part in the concrete can be discharged, so that the utilization rate of the water reducing agent is effectively improved.

Description

technical field [0001] The invention relates to the field of water reducing agents, in particular to a water reducing agent injection pile for concrete. Background technique [0002] With the development of the construction field, there are more and more types of water-reducing agents on the market. Currently, naphthalenesulfonate water-reducers, melamine-based water-reducers, polycarboxylate-based water-reducers, and sulfamate-based water reducers are commonly used. High-efficiency water reducer and so on. [0003] When mixing, the amount of water reducing agent and water consumption should be determined strictly according to the experimental results. When using it, do not increase the amount of water reducing agent or water consumption arbitrarily, so as not to impression the normal construction of concrete. [0004] In the current concrete preparation process, water reducing agent is often added during the mixing process. During the mixing process of concrete, because th...

Problems solved by technology

[0004] In the current concrete preparation process, water reducing agent is often added during the mixing process. During the mixing process of concrete, because the density of concrete raw materials in each part of the concrete is different before the concrete is formed, the moisture content of each part of the concrete is often still different. When reducing After the water agent is mixed into the concrete during the re-mixing process, the dosage of the water-reducing agent required for the concrete area with different water content is different, and the mixing process can only distribute the water-reducing agent evenly into the concrete, and the water-reducing agent takes effect quickly. Existing technology cannot target adding water reducing agent for concrete areas with different moisture content
