Description
Technical field
The utility model belongs to room and builds water supply and sewage work technical field, is specifically related to a kind of direct-burried gutter that carries main equipment or dynamic load ground.
Background technology
Lanzhou heavy ion medical research center magnet power supply test and debugging central steel structure belongs to industrial premises, because equipment in use can be at land drainage, again because the heavy ion experimental facilities of 30 tons (ground design is 300kpa/m) left and right is installed on ground, and its be as dynamic loading on ground, do draining trench and will increase high cost, consider that in addition dynamic load also should not arrange draining trench to the impact of structure, and open drain more there is considerable influence to equipment Foundations.In the building " specification of the buried cast iron pipe pipeline configuration of Water and Waste Water Engineering " that China Engineering Construction Standardization Association formulates, clearly state buried iron drain-pipe construction method and be not suitable for the ground that has large load in industrial enterprise, therefore can only be by gutter direct-burried.Due to direct-burried, cast iron pipe is clamp connection on the one hand, once leak, maintenance will be very difficult; In addition dynamic load, the stronger weakness of its fragility of cast iron pipe will be more outstanding.Because at present also not relevant construction technology can be for reference, therefore the selection of pipe and construction technology are large technical barriers.
Summary of the invention
The technical problems to be solved in the utility model is to provide carrying main equipment that a kind of simple in structure, long service life, cost are low or the direct-burried gutter on dynamic load ground.
It is as follows that the utility model solves the problems of the technologies described above the technical scheme of taking: a kind of direct-burried gutter that carries main equipment or dynamic load ground, comprise floor drain, gutter and threeway, it is characterized in that: gutter comprises iron drain-pipe and steel pipe iron drain-pipe outside suit steel pipe; Steel pipe inner wall is provided with interior anticorrosive coat, and outer wall of steel pipe is provided with external anti-corrosion layer, and iron drain-pipe inwall is provided with anticorrosive coat in cast iron pipe.
Threeway comprises cast iron tee piece, and cast iron tee piece outside is set with steel tee piece, is provided with doughnut-shaped steel plate with the steel tee piece interface upper surface of floor drain butt end; Steel tee piece inwall is provided with interior anticorrosive coat, and steel tee piece outer wall is provided with external anti-corrosion layer; Cast iron tee piece inwall is provided with anticorrosive coat in cast iron pipe.
The utility model carries the direct-burried gutter on main equipment or dynamic load ground, from run into technical barrier analysis, adopts single cast iron pipe or steel pipe obviously all cannot solve this difficulty, if adopt special material cost too high again; So inventor of the present utility model is from using the prerequisite of conventional material, use two kinds of tubing by stack, adopt steel pipe and cast iron pipe simultaneously, at cast iron pipe outside suit steel pipe, Guan Zhongyou pipe, a small amount of draining of holding concurrently of the main pressure-bearing of steel pipe, cast iron pipe arterial drainage, give full play to the advantage of two kinds of tubing, realize advantage and weakness complementation.
Application the utility model is compared with common pipe, and innovation has proposed to roll the way of compacting of adding water in compacting, i.e. " watertight method ", and basis, ground is sand horsestone, layering flattens and tamps, and due to intrinsic spacing between the grains of sand, follow-uply may cause foundation settlement.By pouring water, drive on the one hand the tiny grains of sand to fill space, during on the other hand for follow-up vibrating, lubrication is played in grains of sand motion, has reduced greatly the existence in space, has then avoided foundation settlement.
Application the utility model, effectively avoid the adverse effect that direct-buried pipe is leaked and material corrosion phenomenon causes, solve the severe phenomenon that pipeline that ground dynamic load easily causes crushes, with by the method comparison of reinforcing pipes measure, greatly reduce financial cost, and sand head has also obtained the application of maximum function as waste material.Making has the present situation of the gutter way on the ground of dynamic load to be improved without industrial premises.As calculated, with respect to the construction method that strengthens trench arrangement of reinforcement and reduce the impact that dynamic load causes, the construction of application the utility model is reduced expenses more than 30,000 yuan; Save construction cost more than 50%.
