Description
Technical field
The present invention relates to a kind of cast-in-place concrete pile and job practices thereof.
Background technology
Steel work and concrete are that the builing industry personnel research and develop target in the anticorrosion problem of saline soil area always, and steel and concrete are the main bodys of present various important buildings.The structure of exposing on ground can reach anticorrosion by the various anticorrosive methods of regular brushing, and underground construction is anticorrosion just relatively more difficult.Because member directly contacts with bittern with the salinized soil of deep-etching, can't regularly brush anticorrosive, adopt following two kinds of methods to carry out preservative treatment so people are conventional in the actual engineering:
(1), with the cast-in-place concrete pile of thick walled steel tube parcel and protection, wall thickness is general 〉=10 ㎜.General stake is long at tens meters, 0.5～2.0 meter in stake footpath, and the steel material that this method is used is very big, and cost is very high; These steel are also eroded year by year simultaneously;
(2), adopt anti-corrosion concrete or add the cast-in-place concrete pile of anticorrisive agent material, anticorrisive agent material and anti-corrosion concrete price height, simultaneously concrete intensity reduces and does not reach engine request.
Above two kinds of methods have the cost height of cast-in-place concrete pile, concrete intensity may not satisfy shortcomings such as engine request simultaneously.
And northwest China is distributed with the large tracts of land salt lake, composes here and deposits abundant mineral resources and industrial chemicals, and the large tracts of land that also distributes is unfavorable for the brining ground foundation built.The mineral enterprises here, the industry of chemical enterprise and civilian construction, railway and high-grade highway will be built on these brining ground foundations.The salt marsh distribution area that is rich in bittern is wide, and thickness is big, and the mechanical strength of foundation soil is low, compressibilty is high, and all buildings must adopt artificial foundation or pile foundation; Important building and Rail Highway bridge must adopt the deposited reinforced concrete pile basis.Owing to contain in the brining ground foundation soil building materials such as steel, concrete had the sulfate radical of deep-etching and the bittern of chlorion.Seem particularly urgent so work out a kind of etch-proof pile body of high efficiency, low cost.
Summary of the invention
The purpose of this invention is to provide anti-corrosion inclusion bored concrete pile and job practices thereof that a kind of brining ground foundation is used, solve the preservative treatment cost height that has the saline soil area cast-in-place concrete pile now, the technical problem that might reduce concrete strength; And solve the problem of the concrete job practices of anti-corrosion inclusion bored concrete pile.

Step 3: the clear hole of rig; Start grouting pump, the mud in the stake hole is extracted out from the slip casting pump line;
Step 4: discharge pipe is installed; Remove rig, crane gear and slurry pump are installed on the ground around the stake hole, slurry pump is connected with discharge pipe, and discharge pipe is deep into the bottom in a hole;
Step 5: fixed weight, prepare water proof anti-corrosion protection tube down, be connected crane gear and balancing weight are vertical, the bottom of balancing weight with water proof anti-corrosion protection tube is connected;
Step 6: water proof anti-corrosion protection tube is installed; With crane gear balancing weight and water proof anti-corrosion protection tube are slowly put into the stake hole of having bored at the bottom of stake, then the oral area of water proof anti-corrosion protection tube is fixed;
Step 7: water proof anti-corrosion protection tube is expanded in the water filling plasma discharge; On the ground water injecting pump is installed around the stake hole, water injecting pump is connected with water injection pipe, and water injection pipe is deep in the water proof anti-corrosion protection tube in the hole;
Step 8: start water injecting pump, water filling in water proof anti-corrosion protection tube, start slurry pump simultaneously, discharge the outer cement paste that contains bittern of water proof anti-corrosion protection tube, mud has been arranged outside with water proof anti-corrosion protection tube, and the fresh water of filling with in the water proof anti-corrosion protection tube supports water proof anti-corrosion protection tube with till the stake hole wall engages;
Step 9: reinforcing cage is installed; In water proof anti-corrosion protection tube, be lowered to the reinforcing cage of making is installed;
Step 10: tremie is installed, and the fluid concrete pile; In reinforcing cage, put into tremie, concrete perfusion, the concrete that the fresh water in the water proof anti-corrosion protection tube is injected into squeezes;
Step 11: dismantling concrete conduit; After reaching the design elevation on castinplace pile top water proof anti-corrosion protection tube is closed up, wrapped concrete pouring pile head, and the dismantling concrete conduit, anti-corrosion inclusion bored concrete pile just formed after the concrete setting.
Described step 1 king-pile hole is cylindrical, and rig is spiral drilling machine or rotary disk driller.
Described step 2 holing with slurry wall protection technology is that grouting pump is set near rig, grouting pump is connected with rig by the slip casting pump line, along with the rig drill bit pierces ground, grouting pump injects the stake hole by the cement paste that the slip casting pump line will contain bittern, arrives the stake design attitude at the end until the rig drill bit.
In the described step 6, water proof anti-corrosion protection tube fixes on the ground with the oral area fastening devices through the casing upper edge.
