Abstract
The present invention relates to a technique for seepage prevention and plugging for various underwater or underground buildings or working surfaces in leak conditions, which is widely applied to the technical fields of seepage prevention and plugging in various underwater buildings, foundations, tunnels, bridge piles, cofferdams, etc. The present invention is characterized in that asphalt is heat, and then a refractory heat resistant pump pumps the heated asphalt to a grouting pipeline with the functions of heat insulation and temperature preservation so that the heated asphalt can be easily conveyed to the position seeping water so as to achieve the purpose of plugging is achieved. The present invention has the advantages of low cost, simple technology, construction condition of underground or underwater buildings, such as hydraulic power stations, bridge piles, tunnels, etc., engineering construction quality improvement and construction period reduction.
Description
The invention belongs under water various or underground structure or, specially refer to the anti-seep plugging technology field in various underwater workss and basis, tunnel, bridge pier, cofferdam at the anti-seep plugging technology of the work plane of seepage condition operation.
At the work progress in various hydraulic architectures, tunnel, bridge pier, cofferdam or after building up, normal because percolating water influences the normal construction of engineering or influences the safe handling of building.Watertight grouting leakage stopping technology commonly used is cementation and chemical grouting, and the chemical reaction that they all are based on grouting agent produces a kind of novel substance, reaches the purpose of the impervious leakage-stopping of building.U.S. Pat-3252290 adopts the mulseal greater than water proportion, and the segregation precipitation by pitch particle enters the slit and stops up penetrating passage.Above-mentioned watertight grouting leakage stopping technology, little processing is effective for leakage.Yet dilute the shortcoming that runs off owing to all having by current behind the above-mentioned grouting agent chance water, so the seepage treatment that they are big to flow, flow velocity is high is difficult to prove effective.
Purpose of the present invention just is to provide a kind of being applicable to handle various hydraulic architectures, tunnel, bridge pier, cofferdam in work progress or build up big seepage and the asphalt grouting impervious leakage-stopping method simple, small investment of flow velocity high flow capacity that the back is run into.
Design of the present invention is to be far more than the asphalt grouting physical action, and it is not afraid of flow, flow velocity is big, has the advantages that do not diluted by current and run off.Utilize the physical property of pitch, become after the heating and be easy to flowing liquid, become solid after the cooling again, thereby reach the impervious leakage-stopping purpose.Earlier pitch is heated to proper temperature for this reason, makes it to have certain degree of mobilization, be transported to seepage place again.Because pitch and water do not dissolve each other, heated bitumen promptly is dispersed into some particles after meeting water, and along with constantly pouring into of pitch, the pitch of dispersion constantly condenses and sprawls and come, and sticks on the slotted wall gradually.Along with the continuous thickening of bitumen layer, constantly being contracted to fully of penetrating passage stopped up, thereby reaches plugging function.Because pitch when contacting with water, has formed the bad film of one deck thermal conductivity on its surface, the pitch that pours into cools off slower in crack and hole, the diffusion of the pitch slurries that are highly advantageous to, so it be particularly useful for the slit aperture greatly, flow and the big seepage of flow velocity.
The slit aperture is big in order to handle effectively, flow and the big seepage of flow velocity, and the technology of the present invention key is: the heating-up temperature of first pitch should easily be carried to be as the criterion easily to flow, and heating-up temperature is 120 ℃～200 ℃; Second pump that uses should be resistant to elevated temperatures heat-resisting pump; The 3rd in order to keep asphalt temperature, makes it successfully to send into the rises, and conveyance conduit should be the grouting pipeline of heat-insulation and heat-preservation.
Detailed technology of the present invention is described below:
Earlier pitch is heated to be and is easy to flowing liquid, with pump the heated bitumen pumping is poured into the grout pipe of heat-insulation and heat-preservation again, heated bitumen enters seepage part by the grout pipe of heat-insulation and heat-preservation, after heated bitumen is met water, be dispersed into some particles, the pitch that disperses is cohesion and drawout constantly, sticks to gradually on the slotted wall, along with the continuous thickening of pitch adsorption layer, penetrating passage constantly dwindles until stopping up fully, after impervious leakage-stopping finishes,, use the cleaning agent scavenging pump by pump housing circulation.
According to the requirement of asphalt grouting, described pitch is the pitch of the various trades mark, the various modified bitumens based on petroleum bitumen that comprise bi tumenf orr oad, building petroleum asphalt and common petroleum pitch and add various additives.When specifically selecting the pitch trade mark, should decide according to concrete engine request and used construction machinery.
The firing equipment of pitch is made up of one or more heating tank, and the volume and the quantity of heating tank are decided according to requirement of engineering, and once Jia Re pitch amount will satisfy the grouting consumption of a hole or a hole section.The pitch mode of heating is coal fire heating or firewood heating, is equipped with the air blast facility simultaneously.The heating-up temperature of pitch is decided on the kind of pitch, and mainly easily flowing in course of conveying with pitch is as the criterion, but the maximum heating temperature of pitch must not surpass the maximum heating temperature that this pitch allowed, so the heating-up temperature of pitch is 120 ℃～200 ℃.
Being used to carry the pump of pitch must be resistant to elevated temperatures heat-resisting pump, comprises the motor machine pump of the various suitable asphalt delivery of gear pump, centrifugal pump and reciprocating pump.The discharge pressure of heated bitumen must guarantee heated bitumen is pressed in the penetrating passage and be advisable, and therefore heat-resisting pump discharge pressure is greater than 0.03MPa.After reaching the design discharge pressure, significantly do not inhale slurry and can end grouting.
In addition, if the reduction of the viscosity with temperature of heated bitumen and increasing is the conveyance conduit insulation improper measures of grout pipe (especially imbedding part in the water) particularly.The detemperature rate of heated bitumen is too fast will to be caused heated bitumen to stop up in pipeline and forces grouting to be interrupted.Consider job site service condition, factor such as economical and practical, heat-insulation and heat-preservation grout pipe of the present invention adopts following insulation measure:
(1) less to ponding in hole more shallow grout hole and the hole, the big again and bigger grout hole of grout absorption of hole adopts heat-preserving hose, comprises rubber tube, plastic pipe or adopts steel pipe;
(2) darker to boring, the more grout hole of ponding adopts in the hole: a. steel pipe puts heat-preserving hose outward, comprises that steel pipe puts rubber tube or plastic pipe outward; B. double-layer pipe, filling heat-insulation and heat-preservation material between the steel pipe, the heat-insulation and heat-preservation material is expanded perlite, float stone, glass fiber, asbestos and rock wool etc.
After grouting stops, should be immediately with heating or the cleaning agent through heating do not clean, cleaning agent is the hot water cleaning agent of diesel oil or kerosene or other organic solvent or admixture emulsifier, and emulsifier is various emulsifier and the auxiliary additive thereof that peregal series, OP series etc. can be emulsified into petroleum bitumen the aqueous solution.
