Abstract
The invention discloses a method for cleaning hardened cement mortar on the inner wall of a tube pile steel die. Diluted hydrochloric acid is chemically reacted with the hardened cement mortar on the inner wall of the tube pile steel die to separate the hardened cement mortar from the inner wall of the tube pile steel die to completely clean the hardened cement mortar on the inner wall of the tube pile steel die. The method has the advantages of low labor intensity, high operation speed, cleaning completeness, high efficiency and the like.
Description
Technical field
The present invention relates to a kind of sweep-out method of pile tube punching block inwall hardened cement mortar.
Background technology
In prior art, pile tube produce time because the steel plate of pile tube punching block inwall is not bright and clean, or releasing agent quality is unstable, or releasing agent coating is inhomogeneous, or concrete strength is on the low side, or ambient air temperature is lower and do not take the quiet reasons such as operation of stopping, often occur in after stripping operation and form at pile tube punching block inwall local location the hard hardened cement screed that thickness is 0.1～2.0mm left and right, there is ixoderm and pitted skin phenomenon in the outer surface of the pile tube product after the demoulding simultaneously; If remove not in time the hard hardened cement screed of pile tube punching block inwall, these hard hardened cement screeds can be combined with the cement mortar in fresh concrete next time, continue to accumulate in centrifugal operation, by ixoderm and the pitted skin of aggravation pile tube product external surfaces.The hard hardened cement screed of pile tube punching block inwall is increased to (more than 2mm) after certain thickness may there is local shedding, but because hard hardened cement screed is in the not yet thoroughly removing of pile tube punching block inwall, hardened cement screed hard after 3-5 days slowly starts again to gather at pile tube punching block inwall.If the hard hardened cement screed of pile tube punching block inwall is removed not in time, by ixoderm and the pitted skin of aggravation pile tube outer surface, thereby have a strong impact on the product quality of pile tube and build the long durability of foundation engineering.
Due to pile tube punching block semicircular in shape, radius of curvature is very large, and more than the strength grade of concrete of pile tube reaches C60, the difficulty of the removing of the hard hardened cement mortar of pile tube punching block inwall is much higher than the processing of the cement mortar of hardening on architectural engineering middle plateform punching block.The hard hardened cement screed of the about 0.1～2.0mm that pile tube punching block inwall forms, adopts the polishing of the mechanical system such as drill rod or steel wire or emery wheel conventionally, and these methods fail thoroughly to remove hard hardened cement mortar and the bonding of punching block.
Summary of the invention
The object of the present invention is to provide a kind of sweep-out method of pile tube punching block inwall hardened cement mortar, with daubers such as mops, certain density watery hydrochloric acid is spread upon to the inwall of the pile tube punching block that is stained with hard hardened cement mortar, watery hydrochloric acid and hard hardened cement mortar are after the chemical reaction of certain hour, hard hardened cement mortar comes off from the inwall of pile tube punching block, so just remove the hard hardened cement mortar of pile tube punching block inwall, thereby can reduce pile tube produce in the formation of ixoderm and pitted skin, improve the presentation quality of pile tube product.
Technical scheme of the present invention is: a kind of sweep-out method of pile tube punching block inwall hardened cement mortar, is characterized in that: described watery hydrochloric acid is that concentrated hydrochloric acid and running water are mixed and joined dilution with certain proportion, to the concentration of watery hydrochloric acid be 0.05～0.75N; The watery hydrochloric acid that is 0.05～0.75N by concentration with daubers such as mops, spread upon the inwall of the pile tube punching block that is stained with hard hardened cement mortar, watery hydrochloric acid and hard hardened cement mortar are after the chemical reaction of 1～30 minute, hardened cement mortar comes off from pile tube punching block inwall, wash away or fabric is cleaned the residue of pile tube punching block inwall with running water, so just removed the hard hardened cement mortar of pile tube punching block inwall.
The present invention compared with prior art has the following advantages: a kind of sweep-out method of pile tube punching block inwall hardened cement mortar, adopt and remove in this way the hard hardened cement mortar of pile tube punching block inwall, because the concentration of watery hydrochloric acid is very little, as long as suitable operation, corrosion to people, thing, punching block is very little, the present invention have labour intensity low, swift to operate, remove the advantages such as thorough, efficient.
Detailed description of the invention
A sweep-out method for pile tube punching block inwall hardened cement mortar, mixes concentrated hydrochloric acid and running water to join dilution with certain proportion, to the concentration of watery hydrochloric acid be 0.05～0.75N; The watery hydrochloric acid that is 0.05～0.75N by concentration with daubers such as mops, spread upon the inwall of the pile tube punching block that is stained with hardened cement mortar, after the chemical reaction of 1～30 minute, hardened cement mortar comes off from pile tube punching block inwall, wash away or fabric is cleaned the residue of pile tube punching block inwall with running water, so just removed the hardened cement mortar of pile tube punching block inwall.
Embodiment 1. is that 35% concentrated hydrochloric acid and running water are mixed and joined with certain proportion by technical pure concentration, is diluted with water to the concentration of 0.2N; With mop by dilution after watery hydrochloric acid, spread upon the inwall of the pile tube punching block that is stained with hard hardened cement mortar, after the chemical reaction of 10 minutes, hardened cement mortar comes off from pile tube punching block inwall very soon, then clean the residue of pile tube punching block inwall with fabric, removed the hardened cement mortar of pile tube punching block inwall.
Claims (1)
1. the sweep-out method of a pile tube punching block inwall hardened cement mortar, it is characterized in that: the described watery hydrochloric acid that is 0.05～0.75N by concentration with daubers such as mops, spread upon the inwall of the pile tube punching block that is stained with hard hardened cement mortar, watery hydrochloric acid and hardened cement mortar are after the chemical reaction of 1～30 minute, hardened cement mortar comes off from pile tube punching block inwall, washes away or fabric is cleaned the residue of pile tube punching block inwall with running water.
