Abstract
The utility model provides a steel plate alkali prevention floor which has the layered structure, and is provided with a base layer (1), a cushion layer (2), an alkali resistant cement concrete layer (3), an alkali resistant mortar combination layer (4) and a steel plate surface layer (5) from top to bottom in sequence. The steel plate alkali prevention floor has strong intensity, is not easy to crack, and solves the problem of alkali liquor leakage well; the clean is easy, the leaked alkali liquor is enabled to be easy to flow toward an alkali discharge ditch, thereby a worker is easy to clean the leaked alkali liquor, and the service life of the floor is prolonged. At the same time that alkali prevention of the floor in an alumina workshop of alkaline method production is solved, the requirements of environmental protection and alkali liquor recovery of a factory are also satisfied. The steel plate alkali prevention floor has the identical construction method with the ordinary steel plate floor, and has the advantages of rapid construction, small technical difficulty and easy operation.
Description
Technical field
The utility model relates to a kind of anticorrosion terrace, particularly a kind of anti-alkali floor.
Background technology
In aluminum oxide production process, the mill floor of alkaline process production has alkali liquor leakages such as sodium hydroxide solution.For thereby alkali lye infiltration terrace and the crystallization of terrace lower floor that prevents to leak causes volume expansion to destroy whole terrace, existing standard and existing construction measure are high-strength alkali-resistant concrete surface layer monobloc cast.Though this construction measure globality is strong, can effectively prevent the seepage of alkali lye, along with the passing of service time, the high-strength concrete face will form be full of cracks, thereby causes the seepage of alkali lye.
In the prior art, application number is the construction method that 200410155536.7 Chinese patent has been announced anti-alkali floor, though this terrace has good alkali prevention performance within a certain period of time, but the outermost layer of terrace still is an alkali-resistant concrete, passing along with service time, concrete surface will form be full of cracks, then can cause the seepage of alkali lye equally.
The utility model content
Utility model technical problem to be solved provides a kind of steel plate anti-alkali floor, this terrace utilizes the high-strength and alkaline-resisting characteristic of steel to form a kind of new alkali prevention ground structure measure, thereby the globality of ground surface layer is further improved, the disadvantages such as seepage that cause with the ground surface layer cracking that overcomes in the above-mentioned situation.
In order to solve the problems of the technologies described above, the utility model provides a kind of steel plate anti-alkali floor, is followed successively by basic layer, bed course, alkali-resistant concrete layer, alkaline-resisting mortar setting course and steel plate surface layer from bottom to top.
Basic layer is to contact with ground, compaction in layers, and coefficient of consolidation is not less than 0.9.
Bed course is to be formed by C20 concrete pouring, vibration compacting, and thickness is 100～200mm.
The alkali-resistant concrete layer selects for use the cast of I level alkali-resistant concrete to form, and thickness is 50～150mm.
The thickness of alkaline-resisting mortar setting course is 20～50mm.
For economical with materials, the steel plate in the steel plate surface layer utilizes bionics principle to adopt regular hexagon, and utilizes the material die of steel plate own to go out the anchor pin, guarantees that steel plate combines closely with ground.
The length of side of regular hexagon steel plate is 400～600mm, and thickness is 1.5～3mm, and the distance between them is 50～100mm, punches out 3～6 on anchor pin in every block plate.
Wide 40～the 80mm of anchor pin, long 200～300mm, the degree of depth of inserting in the alkaline-resisting mortar setting course is 15～25mm.
Left vacancy alkaline-resisting mortar levelling when punching out the anchor pin on slit between steel plate surface layer light plate and the steel plate.
Compared with prior art, the steel plate anti-alkali floor intensity height that the utility model provides, not easy to crack, solved the alkali lye leakage problems well; Easy cleaning, the alkali lye that makes leakage is the row's of flow direction alkali ditch easily, and the workman clears up the alkali lye of leakage easily, thereby has prolonged the service life of terrace.The utility model has also satisfied factory's environmental protection in the terrace alkali prevention in the alumina workshop that solves alkaline process production and alkali lye reclaims requirement, and identical with the general steel plate method for constructing terrace, and construction is fast, and technical difficulty is little, easily operation.
Description of drawings
Fig. 1 is a section of structure of the present utility model.
Fig. 2 is the schematic diagram of the utility model steel plate surface layer light plate splicing.
The specific embodiment:
Embodiment: in conjunction with Fig. 1 and Fig. 2 present embodiment is described, the steel plate anti-alkali floor is followed successively by basic layer 1, bed course 2, alkali-resistant concrete layer 3, alkaline-resisting mortar setting course 4 and steel plate surface layer 5 from bottom to top.Basic layer 1 is to contact with ground, compaction in layers, and coefficient of consolidation is not less than 0.9; Bed course 2 is to be formed by C20 concrete pouring, vibration compacting, and thickness is 120mm; Alkali-resistant concrete layer 3 selects for use the cast of I level alkali-resistant concrete to form, and thickness is 60mm; The thickness of alkaline-resisting mortar setting course 4 is 30mm; Steel plate in the steel plate surface layer 5 adopts Fig. 2 structure, be that steel plate is a regular hexagon, the length of side is 500mm, and thickness is 1.5mm, and the distance 7 between steel plate is 60mm, the material die of steel plate utilization own goes out 6 anchor pin 6, anchor pin 6 wide 60mm, long 250mm is inserted in the alkaline-resisting mortar setting course 4, the degree of depth of inserting is 25mm, left vacancy alkaline-resisting mortar levelling when punching out anchor pin 6 on slit between steel plate surface layer light plate and the steel plate.
