Abstract
A process for preparing cast-in-place concrete methane pond of hydraulic type includes digging and forming soil model, depositing concrete to form pond wall and top cover, digging and removing off soil-model soil at material discharging-opening and pond core, depositing pond base concrete, carrying out pond internal sealing treatment with plastic film and erecting not water circulation pipe.
Description
Technical field
The present invention relates to civil works, particularly relate to a kind of concrete marsh-gas pond build process.
Background technology
Biogas utilization is popularized gradually in the rural area, and the construction of biomass pool is similar, so builds and has but shown sizable difference in pond quality, cost input and application life: the brick mix structure of commonplace employing, build a 8m
3Biomass pool, generally cost 1500~1800 yuan, time-consuming taking a lot of work do not say, uses several Nian Houchang corrosion scaling and gas leak phenomenon to occur, has to build again; For the biomass pool building that adopts the whole concrete structure, though the problem of front brick mix structure has solved, but because the difference of construction technology, cost has increased substantially again, by dig pit usually, the traditional handicraft requirement of formwork, pouring, cover and maintenance, pond with top same volume is adjusted, and price cost has surpassed 2000 yuan, and the construction time is long.
Summary of the invention
At the problems referred to above, the present invention makes improvement from building pool process, has proposed some new processes, achieve the goal: ensure the quality of products with long prerequisite of life-span under, cost is descended significantly, and technology is simple, the time is also fast, practice shows, build a biomass pool with top same volume, expense drops to and is no more than 300 yuan, and the time can shift to an earlier date 3~5 days, the technical requirements of construction is low, and everybody can both operate.
Technology of the present invention is still followed the common practices of concrete constructions, include and fetch earth, formwork, water and put operation such as pipe, but mould therefor being native loose tool, is to take the ledge original soil after the fluting cast earlier to the sequence of construction of bay wall body, folder pad plastic sheeting in the groove of cast, cast back one-shot forming.Its concrete technical scheme is as follows:
(1) repair the shoveling loose tool: by the designing requirement unwrapping wire, this line is the surfaces externally and internally size of whole bay wall body, and sweathouse wherein is circular, and discharge room is square or circular; Soil in the sweathouse circle is taken peak position to bay wall downwards along object-line, stop backform and move back platform, dig the bottom, pond more always downwards; With the special-purpose shovel of strip spade, along the internal and external line of discharge room and the inside and outside radial line of sweathouse, do not contain the bonding surface at discharge room and sweathouse top, directly dig at the bottom of the design body of wall of discharge room dark; Repair groove and carry out the pad that native tire bed die is pushed up in the sphere pond, with all die face paving plastic sheetings.
(2) cast bay wall and top cover concrete:, prop up upright good auxiliary template by bay wall thickness at the bonding surface place of sweathouse and discharge room top cover; Wireway is fixed on the peak place of pond top cover,, places feed pipe over against discharge room; By the design proportion requirement, with cement, spun yarn with less than the blinding of 20mm diameter, blunge become reconciled after, closely knitly be poured into the combining in the face wall mould of sealing groove and discharging and sweathouse, then the pond top cover is watered one deck by bay wall thickness shop, note handling well top cover and body of wall bonding surface, repave next day and water one deck, add a cover plastic sheeting afterwards, the earthing maintenance.
(3) take the clay model of the discharging opening and the pond heart: treat that concrete setting can take this part soil on earth in 5~7 days, the fermentation vat bottom can be scraped out lower camber side, at the bottom of the compacting pond, carry out pond subsoil loose tool.
(4) cast pond base concrete: pre-buried three reinforcing bar hooks are poured into a mould the pond base concrete as fixedly adding the hot-water circulation pipe, and will suitably thicken with bay wall bonding surface place at the bottom of the pond.
(5) sealing in the pond: tear the inwall plastic sheeting off, brush several times with being mixed with a certain proportion of ferric trichloride cement paste.
(6) lay and add the hot-water circulation pipe: at the bottom of the plastic conduit dish is put in the pond, fix with the reinforcing bar hook, the two-port of pipe is thrown away by discharge room and connects circulating hot water.
Build process of the present invention, simple, the biomass pool that builds, cost is low, construction is fast, and profile is good, and the life-span is long, biomass pool than brick mix structure, can reduce investment outlay more than 60%, build the pond method than ordinary concrete and reduce investment outlay about 20%, and build pond speed fast 3~5 days, the metope one-shot forming does not have the decortication phenomenon.
Description of drawings
Accompanying drawing 1 is for repairing the signal of shoveling loose tool flow process;
Accompanying drawing 2 is bay wall and the signal of top cover concrete casting injection forming;
Accompanying drawing 3 builds up the back signal for biomass pool.
Among the figure, 1 for pressing the design unwrapping wire, and 2 for having taken Chi Ding and most of pond cubsoil, and 3 is the moulding soil loose tool after shovel digs bay wall soil, and 4 is the moulding bay wall of caping; 5 are the air guide tubule, and 6 is feed pipe, and 7 is the reinforcing bar hook, and 8 is the heat cycles pipe, and 9 is plastic sheeting.
The specific embodiment
The present invention is illustrated as example according to Fig. 3, specifically implements as follows:
The specification of biomass pool: fermentation vat is circular, diameter 240cm, and discharge room selects square, each 100cm of length and width, the total depth in pond is about 250cm, and bay wall thickness selects 8cm, the thick 15cm of top cover, at the bottom of the pond circular arc, suitably thicken with the bay wall junction at the bottom of the pond, the upper edge of bay wall is about 80cm far from ground, about the high 125cm of wall, wireway is contained in the centre of top cover, diameter 10mm, feed pipe be over against charging aperture, diameter 20~30cm, the straight cutting oblique cutting all can, make of sheet iron, the heat cycles pipe selects plastic conduit, and diameter is not limit, the length of spiraling 60~80m draws from discharging opening.
Construction technical requirement: carry out in proper order by foregoing concrete technical scheme requirement.Be filled into from 20cm place, top at the bay wall body, with the used concrete of top cover, need in concrete, to add a certain proportion of ferric trichloride, for guaranteeing the intensity of pond top cover, the top cover cast is carried out at twice, its final grouting needs to carry out after 24 hours in head time pouring, in addition also need be thicker at the charging aperture place, and the levelling press polish, cover one deck plastic foil, water seasoning, backfill after the initial set, the deposition of watering.Need join special-purpose stripe shape shovel spade during shoveling loose tool groove; All die faces are all wanted shaping and are attached plastic sheeting.
