Description
Technical field
The utility model relates to a kind of composite pile, especially relates to a kind of concrete tube core corrosion protection post.
Background technology
In medium, severe corrosive environment, the erosion of prefabricated tubular pile corrosion-vulnerable medium, can there is chemical reaction in the Behavior of Hardened Cement Paste of corrosive medium and prefabricated tubular pile and reinforcing bar, impel Behavior of Hardened Cement Paste acidolysis and corrosion of steel bar, thus affect the durability, pile strength etc. of prefabricated tubular pile.For the problems referred to above, the conventional anti-corrosive measure of current employing have adopt special corrosion-resistant cement make prefabricated tubular pile, prefabricated tubular pile external surface brushing or spray organosilyl protective agents etc., although above-mentioned anticorrosive measure can reach etch-proof object, but exist significantly not enough, such as: adopt special corrosion-resistant cement to make the method cost of prefabricated tubular pile high; Prefabricated tubular pile side friction can be reduced in the external surface brushing of prefabricated tubular pile or the method for injection organosilyl protective agents, thus affect the supporting capacity of prefabricated tubular pile.
Summary of the invention
Technical problem to be solved in the utility model is to provide that a kind of cost is low, anticorrosive property good, and the concrete tube core corrosion protection post that supporting capacity is high.
The utility model solves the problems of the technologies described above adopted technical scheme: a kind of concrete tube core corrosion protection post, it is characterized in that being included in the outer core of the solidified earth formed in soil treating region, the center of the outer core of described solidified earth has set concrete pipe, the degree of depth of the outer core of described solidified earth exceedes the lower limit 1 ~ 2m in the fluctuation of water table district in the soil treating region at its place, and the minimum diameter of the outer core of described solidified earth is that the diameter of described concrete pipe adds 30cm and must not be less than 1m.
The outer core of described solidified earth is formed soil solidification process in soil treating region; At this, solidification processes the corrosive medium in the curing compound meeting passivation soil adopted, and therefore anticorrosion ability is good.
Compared with prior art, the utility model has the advantage of:
1) the outer core of the solidified earth in this concrete tube core corrosion protection post for directly to be formed in soil treating region, and not only cost is low, and can combine well with concrete pipe, and anticorrosive property is good, and can improve the supporting capacity of single pile significantly.
2) owing to corroding usually in tidal zone, therefore make the degree of depth of the outer core of solidified earth exceed the lower limit 1 ~ 2 meter in the fluctuation of water table district in the soil treating region at its place, effectively can prevent the erosion of corrosive medium, make anticorrosive property better.
3) outer for solidified earth core being designed to minimum diameter is that the diameter of concrete pipe adds 30cm and must not be less than 1m, and make the supporting capacity of single pile higher, anticorrosive property is better.
4) this concrete tube core corrosion protection post in the preparation, and form the outer core of solidified earth by being cured process to soil, and solidification processes the corrosive medium in the curing compound meeting passivation soil adopted, therefore anticorrosion ability is good.
Accompanying drawing explanation
Fig. 1 is the schematic cross-section of concrete tube core corrosion protection post of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing embodiment, the utility model is described in further detail.
A kind of concrete tube core corrosion protection post that the present embodiment proposes, as shown in the figure, it is included in soil treating region the outer core 1 of solidified earth that soil solidification process is formed, the center of the outer core 1 of solidified earth has set concrete pipe 2, the degree of depth of the outer core 1 of solidified earth exceedes the lower limit 2 meters in the fluctuation of water table district in the soil treating region at its place, the minimum diameter of the outer core 1 of solidified earth is that the diameter of concrete pipe 2 adds 30cm and must not be less than 1m, such as: suppose that the diameter of concrete pipe is 60cm, the minimum diameter then requiring the outer core 1 of solidified earth is 1m, and namely diameter can be 1m or is greater than 1m as 1.2m; Suppose that the diameter of concrete pipe is 90cm, then require that the minimum diameter of the outer core 1 of solidified earth is 1.2m, namely diameter can be 1.2m or is greater than 1.2m as 1.5m.
At this, the lower limit 1 ~ 2 meter that the degree of depth of the outer core of solidified earth exceedes the fluctuation of water table district in the soil treating region at its place all can play good anticorrosive property, therefore can according to the degree of depth of the outer core of actual conditions determination solidified earth when practice of construction.
The preparation process of this concrete tube core corrosion protection post is:
1. water level exploration is carried out to pending soil treating region, determine the lower limit in the fluctuation of water table district in soil treating region; And geological prospecting is carried out to soil treating region, according to engine request and geological prospecting situation, determine diameter and the length of the concrete pipe that should arrange in soil treating region.
2. soil stabilization is adopted to be cured process to the subregion that should arrange concrete pipe in soil treating region, form the outer core of solidified earth, and make the degree of depth of the outer core of solidified earth exceed the lower limit 2 meters in the fluctuation of water table district in soil treating region, and the diameter that the minimum diameter of the outer core of solidified earth is concrete pipe adds 30cm and must not be less than 1m.
At this, the lower limit 1 ~ 2 meter that the degree of depth of the outer core of solidified earth exceedes the fluctuation of water table district in the soil treating region at its place all can play good anticorrosive property, therefore can according to the degree of depth of the outer core of actual conditions determination solidified earth when practice of construction.
At this, it is patent No. construction mechanical device for fast consolidation of tidal marsh mud disclosed in the Chinese utility model patent of 201020546026.3 that solidification processes the curing adopted, the water/binder ratio of the curing compound slurries adopted is 0.5 ~ 1, if employing water/binder ratio during Specific construction is the curing compound slurries of 0.8, curing compound in curing compound slurries is patent No. quick sea coating mud consolidation agent disclosed in the Chinese invention patent of 201010268432.2, both combine and effectively can improve solidification effect, thus effectively can improve the supporting capacity of anticorrosive property and single pile.Certainly, also other curing and curing compound can be adopted according to execution conditions during Specific construction, as adopted the BMW lorry mounted mixer through repacking.
Determine curing compound blending ratio when carrying out soil test, blending is than between 5% ~ 12%; Again according to the water/binder ratio of project silt moisture content, curing compound construction fed distance determination curing compound slurries, the water/binder ratio of curing compound slurries controls 0.5 ~ 1.
3. before the outer core initial set of solidified earth, set concrete pipe at the center of the outer core of solidified earth, the construction operation process that sets of concrete pipe is: pile-forming machine perching-check stake position-hang a pitching pile-pile body centering straightening-static pressure pile-sinking-pile extension-static pressure pile-sinking-pile follower again-terminations piling-quality of pile to check.
4. after the outer complete consolidation of core of solidified earth, concrete tube core corrosion protection post is formed.Generally, the outer core of maintenance more than 28 days solidified earth can consolidation completely.
