Abstract

The utility model discloses an anti-corrosion treating device for on-the-spot pouring piles, the purpose is to solve the problem that the piles of finished products in anti-corrosion construction of extra grade for piling of outer anticorrosive coating are easy desquamate. The utility model is that an upper slurry transferring pipe is installed on a pile pipe to convey anti-corrosive paint into an upper fixed slurry discharging ring and a lower fixed slurry discharging ring; anti-corrosion slurry is coated between pouring material and a soil layer by the control of a slip ring.

Description

The cast-in-place peg corrosion protected treatment device

The utility model is a civil engineering field construction equipment, is a kind of cast-in-place peg preservative treatment equipment that is used for particularly.

At present; in place with severe contamination corrosion; need extra protection to handle pile foundation; under using the invalid situation of sulfuric-resisting salt solution liquid finished peg, be coated with the corrosion-inhibiting coating method outside adopt more; but the finished peg of empirical evidence corrosion-inhibiting coating is difficult to protection in the piling process lives coating, so do not reach superfine anticorrosion purpose.

The utility model provides a kind of new corrosion protected treatment device, makes it to finish a top layer preservative treatment job in the process of cast on-site.

The utility model is to realize like this, on the stake pipe of former rapping extractor, vertically connect 2 to 3 and send the slurry pipe, retainer plate and following retainer plate in the welding of stake pipe lower end, upper and lower retainer plate is managed UNICOM with sending slurry, and a corresponding side is established some even plasma discharges hole, establishes one and can and send the slurry pipe slip ring that easy on and off slides along the stake pipe between upper and lower plasma discharge circle.When the stake pipe was descending in the stake hole, impregnating fluid was squeezed into by pump and is sent slurry pipe, and the frictional resistance that relies on slip ring and stake hole wall is controlled plasma discharge hole up and down, makes it to finish the purpose of coating impregnating fluid between stake hole wall and cast-in-place peg.

The utility model is the anticorrosion equipment that carries out simultaneously of cast-in-site; corrosion-inhibiting coating is protected in construction, in the civil engineering that needs extra protection to handle, not only protected corrosion-inhibiting coating also can adopt general cement and the construction of reinforcing bar material like this; save manpower and material, greatly reduced cost.

Fig. 1 is the utility model cast-in-site corrosion protected treatment device schematic diagram.

Fig. 2 is that the A-A of the utility model Fig. 1 is to sectional view

Fig. 3 is that the B-B of the utility model Fig. 1 is to sectional view

Below in conjunction with accompanying drawing the utility model is described in further detail.

When stake pipe on the rapping extractor 71 is descending in the stake hole, the anticorrosion slush pump of breakdown send slurry with anticorrosion slurries by force feed slurry pipe 2 simultaneously, manage 1 when descending when stake this moment, movable slip ring 4 is because of being subjected to a hole wall frictional resistance up, block the plasma discharge hole 8 of retainer plate 3, at this moment slurries squeeze out even anticorrosion slurry by the plasma discharge hole 8 of retainer plate 5 down and are coated on the hole under certain hydraulic pressure, after at the bottom of stake pipe 1 reaches a hole, in stake pipe 1, throw and irritate pile shaft material, after throwing is filled, a pipe of extricating oneself from a predicament and brace oneself up to action is stayed precast pile tip 6 and pile shaft material in the hole, at this moment, slip ring 4 is subjected to a hole wall frictional resistance descending, blocks down the plasma discharge hole 8 of retainer plate 5, at this moment go up the plasma discharge hole 8 unimpeded plasma discharges of retainer plate 3, with anticorrosion slurries extrusion coated on cinclides.

The utility model can up and down reciprocatingly be coated with each once for best in construction, but as required also one way be coated with, or multipass is coated with, and how much how much controls the coating pass with the geological conditions situation and with the slurry amount.

Claims

A kind of cast-in-place peg corrosion protected treatment device of forming by stake machine, stake pipe, it is characterized in that stake pipe (1) is equipped with send slurry pipe (2), stake pipe (1) and send slurry pipe (2) lower end to have to go up fixedly plasma discharge circle (3) and following fixedly plasma discharge circle (5) and manage (2) and communicate with sending to starch, go up fixedly plasma discharge circle (3) and fixedly on plasma discharge circle (5) corresponding surface some plasma discharges hole (8) arranged down, on fixedly plasma discharge circle (3), fixedly have can and send along stake pipe (1) to starch in the middle of the plasma discharge circle (5) and manage the slip ring (4) that (2) slide up and down down.
