Abstract
The invention provides a method for removing hardened cement mortar on the inner walls of pipe pile steel formworks, which is characterized in that a pipe pile centrifuge implements centrifuging by taking granitic cobblestones and gravels or steel balls for the grinding of cement as a grinding material in centrifuging; the hardened cement mortar adhering on the inner walls of the steel formworks is cleanly removed through the turning and tossing of the grinding material and the collision and friction of the grinding material against the inner walls of the steel formworks in centrifuging. By the adoption of the method, the centrifuge of a pipe pile production line can be utilized without other equipment being added; moreover, the removal of the hardened cement mortar is high in efficiency and high in speed.
Description
Technical field
The present invention relates to a kind of method of removing 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 hard hardened cement mortar of pile tube punching block inwall and the adhesion strength of punching block inwall are very high, and the difficulty of removing is much higher than the conventional cement mortar hardening on architectural engineering middle plateform punching block.The hard hardened cement screed of 0.1～2.0mm left and right that pile tube punching block inwall forms, conventionally adopt the mechanical system polishings such as drill rod or steel wire or emery wheel, these methods fail thoroughly to remove hard hardened cement mortar and the bonding of punching block, and efficiency is not high, effect is not remarkable.Through inquiry, adopt centrifugal process to remove pile tube punching block inwall hardened cement mortar, the current report there are no this respect.
Summary of the invention
The object of the present invention is to provide a kind of method of removing pile tube punching block inwall hardened cement mortar, on tubular pile centrifugal machine, cobblestone, rubble that the stone matter that adopts production pile tube to use is granite, or the abrasive material of the steel ball used of pulverizing cement when centrifugal as pile tube punching block, carry out centrifugal operation, utilize the rolling of abrasive material in pile tube punching block and collision and the friction of throwing, material and punching block inwall when centrifugal, the hardened cement mortar that is bonded in punching block inwall is removed clean.
Technical scheme of the present invention is: a kind of method of removing pile tube punching block inwall hardened cement mortar, a certain amount of pile tube is produced to the cobblestone that the stone matter that is 5～25mm with particle diameter is granite, rubble, or the steel ball that the diameter used of pulverizing cement is 5～50mm is as abrasive material, be placed in the female die of pile tube punching block that inwall is stained with hardened cement mortar, upper half pile tube punching block closes, tighten die bolt, then the pile tube punching block after getting togather is placed in and on tubular pile centrifugal machine, carries out centrifugally operated, control centrifugal speed is 50～150r/min, centrifugation time is 5～60min, utilize rolling and the throwing of abrasive material in pile tube punching block when centrifugal, collision and friction that abrasive material and punching block inwall occur, the hardened cement mortar that is bonded in punching block inwall is removed clean, described feature is: the consumption of cobblestone, rubble or steel ball by volume calculates as 5～40% of pile tube punching block cavity volume.
The present invention compared with prior art has the following advantages: a kind of method of removing pile tube punching block inwall hardened cement mortar, while adopting the hardened cement mortar of removing in this way punching block inwall, raw material and the centrifuge instrument that can utilize pile tube to produce, need not increase other equipment, and the effect of removing hardened cement mortar is high, speed is fast.
The specific embodiment
A kind of method of removing pile tube punching block inwall hardened cement mortar, pile tube is produced to the cobblestone that stone matter that the particle diameter of use is 5～25mm is granite, rubble, or the steel ball that the diameter used of pulverizing cement is 5～50mm is as abrasive material, be placed in the female die of pile tube punching block that inwall is stained with hardened cement mortar, upper half pile tube punching block closes, tighten die bolt, then the pile tube punching block after getting togather is placed in and on tubular pile centrifugal machine, carries out centrifugally operated, control centrifugal speed is 50～150r/min, centrifugation time is 5～60min, utilize rolling and the throwing of abrasive material in pile tube punching block when centrifugal, collision and friction that abrasive material and punching block inwall occur, the hardened cement mortar that is bonded in punching block inwall is removed clean.Described feature is: the consumption of cobblestone, rubble or steel ball by volume calculates as 5～40% of pile tube punching block cavity volume.
The steel ball that embodiment 1. is 20mm by the pulverizing cement of 1.0 tons of weights with diameter, being placed on the internal diameter that is stained with hardened cement mortar is 400mm, length is in the female die of pile tube punching block of 11m, upper half pile tube punching block closes, tighten die bolt, then the pile tube punching block after getting togather is placed in and on tubular pile centrifugal machine, carries out centrifugally operated, control centrifugal speed is 80r/min, centrifugation time is 10min, utilize rolling and the throwing of steel ball in pile tube punching block when centrifugal, collision and friction that steel ball and punching block occur, the hardened cement mortar that is bonded in punching block inwall is removed clean.
