Abstract
The invention discloses a construction method for clearing away waste soil nails and anchor rods in soil by utilizing an electrolytic corrosion technology. The construction method adopts an electrolytic principle and comprises the steps of: connecting a direct-current power supply between two of the soil nails or the anchor rods which need to be cleared away; and energizing by utilizing the moisture or the ground water contained in the soil as an electrolyte solution to ensure that the metal atoms on the soil nails or the anchor rods which are connected with the positive pole of the direct-current power supply lose electrons and are oxidized and corroded till the soil nails or the anchor rods which need to be cleared away disappear. The method not only can be used for effectively and rapidly clearing away the waste soil nails and the anchor rods buried in the soil, but also has the advantages of fewer needed operating personnel, low construction cost, shorter construction period, and has greater dissemination and application value.
Description
Technical field
The present invention relates to a kind of constructional method for building, particularly a kind of constructional method of utilizing the electrolytic corrosion technology to remove discarded soil nailing anchor pole in the soil.
Background technology
In the building foundation pit construction process, sometimes adopt and in the foundation ditch periphery soil body, squeeze into soil nailing or anchor pole is kept the stable of the soil body, it is main bearing member that these soil nailings or anchor pole generally adopt steel, finish, behind the foundation ditch periphery backfilling of earthwork, just no longer need soil nailing or anchor pole to keep the stable of the soil body Deng foundation ditch inside subject structure construction.At this moment, just ineffective at the native intravital soil nailing of periphery, anchor pole, but most of because of darker in the embedding soil, be difficult for to take out, take recyclable technology, often just abandon in soil, generally can not be corroded, become the underground obstacle in underground iron and steel rubbish and later adjacent architectural building site.
Summary of the invention
In order to overcome the deficiencies in the prior art, the invention provides a kind of can accelerate irony objects such as soil nailing, anchor pole in the underground corrosion process to reach the constructional method of removing purpose.
The technical solution used in the present invention can be described as:
A kind of constructional method of utilizing the electrolytic corrosion technology to remove discarded soil nailing anchor pole in the soil, it utilizes electrolysis principle, insert a direct supply between the soil nailing of two needs removings or the anchor pole therein, utilize the moisture or the underground water that contain in the soil to be electrolytic solution, atoms metal loses the oxidized corrosion of electronics on soil nailing that the energising back is connected with described dc power anode or the anchor pole, infiltrate in the soil with the ionic form, until disappearance, variation as negative pole is little, can the chap because of electrolytic action.
The invention has the beneficial effects as follows:
In the present invention, discarded soil nailing in the soil is applied a volts DS utilizes electrolysis principle to accelerate to be embedded in the metal soil nailing in the soil or the oxidation corrosion of anchor pole, to reach the purpose of removing, this electrolysis process can not only be removed discarded soil nailing or the anchor pole of imbedding in the soil effectively apace, and the action required personnel are few, construction cost is low, the duration is short, have bigger application value.
Description of drawings
Fig. 1 is an enforcement synoptic diagram of the present invention.
Embodiment
As shown in Figure 1, a kind of constructional method of utilizing the electrolytic corrosion technology to remove discarded soil nailing anchor pole in the soil, it at first removes the earthing at discarded soil nailing or anchor pole 1 top, connect the top that 2 soil nailings or anchor pole 1 expose the soil body respectively with the anchor clamps 4 of tape insulation handle then, anchor clamps 4 are connected with the positive and negative electrode of external power source 2 respectively by cable 5, this outside power supply 2 adopts low-voltage dc power supply, generally can adopt DC welder or the generator being convenient to move.If adopt AC power, then should be equipped with rectifier, low-voltage transformer, change alternating-current into low-voltage DC output.
The workmen should determine electrical current intensity according to clean-up time, two soil nailings or 1 distance of anchor pole, soil nailing or anchor pole 1 depth of burying.Generally get adjacent two soil nailings or anchor pole 1 as positive and negative electrode, spacing is 1.0～3.0m, and strength of current is controlled at 0～500A; Voltage is unsuitable too high, generally is controlled in the 100V.
After connecting power supply, the intermittence energising.Under the effect of dc voltage and current, by the moisture 3 that contains in the soil as electrolytic solution, atoms metal on anode soil nailing or the anchor pole 1 loses electronics and oxidized corrosion, metal ion infiltrates soil, along with voltage raises, electric current reduces, and anode anchor pole or soil nailing 1 variation in diameter are until disappearance, and electric current is zero.After treating that an anode soil nailing or anchor pole 1 are eliminated, change another root soil nailing or anchor pole 1, be eliminated until all soil nailings that need remove or anchor pole 1 as anode.
