Description

A kind of foam cement and the method for building methane-generating pit with this cement thereof
Technical field
The present invention relates to the material of construction and the method for construction thereof of methane-generating pit.
Background technology
At present, at Heilongjiang Province rural 8～100m 3Its main raw of using of construction of small-sized methane pond be cement and common brick, adopt the processing method that cement waters or common brick is built by laying bricks or stones to build.Along with the variation of the Northeast's temperature in four seasons, the crack appears in the pond body of methane-generating pit easily, causes the biogas in the methane-generating pit to leak, and the serious methane-generating pit that causes is scrapped, working life short (can use more than 5 years household small-size methane-generating pit seldom); It is material of construction that existing methane pool adopts high cement, the common brick of thermal conductivity, make the methane-generating pit heat-insulating property poor, temperature in the winter methane-generating pit is below 10 ℃, bacterial classification can't be survived, methane-generating pit can not aerogenesis, adopt the outer cost height that replenishes heat energy, waste energy, cause the utilization ratio of methane-generating pit low.
Summary of the invention
The present invention is in order to solve existing methane-generating pit along with temperature in four seasons changes, and the pond body is prone to the crack, and the methane-generating pit life-span is short; The existing methane pool heat-insulating property is poor, the interior temperature of methane-generating pit in winter is lower than 10 ℃, bacterial classification can't be survived, methane-generating pit can not aerogenesis, cause the low problem of utilization ratio of methane-generating pit, the method that a kind of foam cement is provided and has built methane-generating pit with this cement, the concrete technical scheme that addresses the above problem is as follows:
Every cubic metre of foam cement of the present invention is by weight being that 9.6～128kg, water 200～350kg are formulated by cement 320～640kg, splash card F-500 cement blowing agent or HF-30 synthetic water cement foaming agent 0.5～2.35kg, UEA cement expansive material or CSA cement expansive material.
The step of the method for construction of foam cement methane-generating pit of the present invention is as follows:
Every cubic metre of step 1, foam cement are by weight being that 9.6～128kg, water 200～350kg prepare by cement 320～640kg, splash card F-500 cement blowing agent or HF-30 synthetic water cement foaming agent 0.5～2.35kg, UEA cement expansive material or CSA cement expansive material;
Step 2, will be set by step the foam cement that stirs of a preparation be filled in the mould of pond body;
5～10cm in the upper surface of pond body is inserted in step 3, the bottom that will tie up top, the pond Framework Of Steel Reinforcement finished of system;
Step 4, the foam cement that secondary pouring step 1 preparation stirs in the backform tool of pond are again removed mould after health, and are coated with one deck water-proof material get final product on pond body and top, pond inwall.
The foam cement that the present invention adopts can effectively solve 8～100m 3Body crack, small-sized methane pond, the problem that biogas leaks and methane-generating pit work-ing life is short.The minimum use of foam cement methane-generating pit of the present invention 30 years (having improved 5 times work-ing life) than existing methane-generating pit.The inner small pore of sealing uniformly that forms of foam cement methane-generating pit pond body, not only blocked water but also damp proof insulation, but also insulation, the thermal conductivity of foam cement methane-generating pit is 0.087w/mk, and the thermal conductivity of cement casting methane-generating pit is 2.87w/mk, the thermal conductivity of common brick methane-generating pit is that (thermal conductivity of the methane-generating pit of common brick building is 9 times of foam cement methane-generating pit thermal conductivity to 0.81w/mk, the thermal conductivity of the methane-generating pit of cement works is 32 times of foam cement methane-generating pit thermal conductivity), the foam cement methane-generating pit has improved the insulation degree in the methane-generating pit, be beneficial to growth, not only improved the factor of created gase of methane-generating pit, saved the energy again, and can guarantee that methane-generating pit can normally move throughout the year, has improved the utilization ratio of methane-generating pit.
