The present invention relates to the technical field of construction work leak preventing and leak stopping. Particularly a leak preventing and leak stopping method and the leak stopping material thereof. The method carries out the leak stopping for construction work and buildings by using a natural foaming function of kelps. According to weight percentage, the raw material of the leak stopping material comprises (1) 30 to 70 wt% of kelps, (2) 5 to 20 wt% of flyash, (3) 5 to 20 wt% of gypsum powder, (4) 5 to 20 wt% of standard cement and (5) 0 to 20 wt% of other admixture. The present invention mainly solves the technical problems of high producing and processing cost and multiple chemical components of the existing leak stopping material, an original soil layer is damaged after leak stopping, and the groundwater resource is polluted for a long term; in addition, the cost is low.
Description
Technical field:
The present invention relates to construction works antiseep and leakage stopping technology field, particularly a kind of loss circulation material that is used for antiseep and blocking method.
Background technology:
Antiseep in the construction works and leak-stopping technique are very crucial concerning construction and construction quality, and it is related to the application life of construction project and building and the life security of numerous people.The particularly extensive increase that drops into along with China infrastructure, in the infrastructure and architecture construction of coastal, city along the river, antiseep and the leak-stopping technique effect of strengthening construction project and building are very important.
Below be several existing loss circulation materials:
1, Chinese invention patent prospectus (CN1560171A) discloses a kind of high-performance cement-based sealing loss circulation material.By Portland cement, high alumina cement, 0.16-2.5mm quartz sand, cellulose, water reducing agent, gypsum, calcium lime powder are formed, use the present invention can mix the clay of system rapid condensation sclerosis, seepage part to buildings (structure) such as roof, metope, ground, dam, tunnel, ponds carries out sealing leak stopping processing very expeditiously, thereby thoroughly administer seepage, improve the human settlement significantly, prolong concrete structure (structure) application life.The present invention is applicable to works (structure) such as steel concrete, light aggregate concrete, industry and civilian construction, basement, bridge, dam, tunnel.
2, Chinese invention patent prospectus (CN1052351A) discloses a kind of stratum blocking agent with polyurethane foam, and it is that polyurethane foam is processed into agent, sneaks into drilling fluid with 0.2～1% prescription and injects the leak stopping location; Can with the various drilling fluid compatibilities of different densities, have no adverse effects; Not strict to the requirement of prescription height, the compatibility process is simple, and is easy to operate; Good intermiscibility is arranged, can use with other sealing agent compatibility, effect is better, and its source of goods is abundant, and cost is low, be to adopt 1/10th and 1/4th of chemistry and bridging plug leak stopping cost, and be stratum loss circulation material more satisfactory, less expensive.
3, existing in the market water soluble polyurethane leak-stopping agent is a main product.Though the effect of polyurethane is a lot, have many uses too, the cost costliness of its production and processing, chemical analysis is very big, after the leak stopping destruction of former soil layer and the long-term pollution of groundwater resources is well imagined.Soluble polyurethane system carries out the macromolecular compound that polymerisation becomes by toluene di-isocyanate(TDI) (TDI) with water soluble polyether, and its performance indications are:
| Sequence number | Project | Index |
| 1 | Density, g/cm 3 | ?1.03～1.10 |
| 2 | Viscosity, Map | ?100～400 |
| 3 | The rate of rising of splashing, % | ?≥350 |
| 4 | The induced gel time, S | ?10～1200 |
The production and sales price is: 31.50 yuan/kg.Transportation after the packing and storage all have strict safety requirements, so belong to typical chemical industry product.
Summary of the invention:
The object of the present invention is to provide a kind of loss circulation material that is used for antiseep and blocking method, solve the cost costliness of existing loss circulation material production and processing, chemical analysis is very big, after the leak stopping to the technical problem of the long-term pollution of the destruction of former soil layer and groundwater resources.
For solving the problems of the technologies described above, invention is achieved in that
A kind of antiseep and blocking method is characterized in that: utilize the natural frothing function of sea-tangle that construction project and building are carried out leak stopping.
Be processed into Powdered after the natural plants sea-tangle dried.
A kind of loss circulation material mainly utilizes the natural frothing function of sea-tangle that construction project and building are carried out leak stopping, it is characterized in that its raw material comprise according to percentage by weight:
(1) sea-tangle 30-70%;
(2) flyash 5-20%;
(3) land plaster 5-20%;
(4) standard cement 5-20%;
(5) other admixture 0-20%;
Wherein, sea-tangle be processed into after the natural plants sea-tangle is dried Powdered.
Be processed into Powderedly after the natural plants sea-tangle dried, add flyash again and land plaster and standard cement etc. mix.
Various raw-material technical datas are as follows:
(1) sea-tangle expansion rate 〉=500%;
(2) flyash flowability 〉=70%;
(3) land plaster solidification rate 〉=300%;
(4) standard cement intensity rate 〉=100%;
(5) other admixture is brought rate 〉=60% together.
The specific embodiment:
The invention provides a kind of antiseep and blocking method and a kind of foaming loss circulation material, this loss circulation material is to belong to raw material synthesis type product, in the effect not second to polyurethane of the effect of former soil layer leak stopping, and can not pollute original water resource.It is after drying with the natural plants sea-tangle fully, is processed into Powderedly, adds a kind of natural material water-proof material that flyash and land plaster and standard cement etc. mix again.Its effect is:
1, the sea-tangle after drying has the function of natural foaming, and contains a large amount of enzyme elements in plant, can play the effect of expanding naturally in moisture native soil.And play the effect of the anti-leakage that certain flowing water is obstructed.
2, flyash is a kind of electrolytical product, and its is mobile fabulous, finds the main channel of leaking easily, and can constantly spread closely knitly, and its function is can temporary transient closely knit soil layer.
3, land plaster is a kind of CaSO
3-CaCO
3Mixture, the material of solidified water molecule in large quantities, and can temporarily play the flowability of control water, in native soil, can play certain freezing action; And add standard cement when stirring into slurries, and be can cooperate above three kinds of mixtures to flow to the leak stopping position of appointment together, thereby play the effect of raising intensity, guarantee the long-time firm effectiveness after the leak stopping.
Embodiment 1:
Use the natural sea-tangle after drying separately, and be processed into Powdered back as material water-proof material.
Embodiment 2:
A kind of loss circulation material, its raw material comprise according to percentage by weight:
