The specific embodiment
The total design of the utility model is: a sleeve part is provided; Strengthen the angle between main comb and the outer comb, force outer comb to tilt and arrive sink hole, compare with the mode that the horizontal under the frozen soil layer of outer comb is at present passed through through frozen soil layer; The pipeline current are unobstructed, can not stop up.Introduce two kinds of embodiment below in conjunction with accompanying drawing:
The house (1) that first kind of embodiment: Fig. 1 gives an example is the five floor rooms that are divided into by five layers of floor (2), and the sewer pipe in the building comprises a main comb (3) and a comb (4).Main comb (3) is erect and is installed, and runs through five floors.Comb (4) is connected between water consumption device (5) such as urinal or wash basin and the main comb (3).Lower end in main comb (3) connects an outer comb (9) through external threeway (8), and outer comb (9) is from underground the passing through of outside, house; Insert sink hole (10); Sink hole (10) is located at the building outside, and sink hole (10) the inside is provided with blow-off line (11), and the position of blow-off line (11) is lower than the frozen soil layer in local winter; Blow-off line (11) connects other sewage disposal facilities, and effluent discharge is gone out.Its special character is: outer comb (9) promptly gets into frozen soil layer (13) after indoor picking out, and downward-sloping frozen soil layer (13) the entering sink hole (10) that passes, and arrives at the top of blow-off pipe (11).Can calculate the axis angle=90 °+α of main comb (3) and outer comb (9) thus, wherein, α is the angle on outer comb (9) and ground (12); If the distance=H on the thickness=blow-off line (11) of frozen soil layer (13) and ground, the horizontal range=L of blow-off line (11) and external wall of house face then has sin α=H: L; Suppose frozen soil layer (13) 1.5m; The distance of sink hole (10) and external walls of building is 5m, and the substitution following formula gets sin α=1.5/5=0.3, checks in α=17.5 °.
Suppose 5m in the outer comb inlet chamber, and still fair with the tie point of main comb (3) with ground, perhaps outer comb (9) is frozen soil layer (13) outside below ground 70-80cm gets into the room, so: sin α=1.5/10=0.15, a=8.7 °.The experiment proof: such angle of inclination also can obtain significant blocking-proof result.
For the space of better utilization frozen soil layer, the section that outer comb (9) is crossed wall face and the distance on ground to be being no more than 10cm, and outer comb (9) to cross blow-off line (11) top that frozen soil layer (13) locates to arrive in the sink hole (10) be preferably.Certainly, this mode must notice that the exterior wall of building is neighbouring inaccurate through weight, in order to avoid damage outer comb (9) by pressure.Observe proof, generally do not have vehicle pass-through near the foot of a wall, result of use is best.
Outer comb (9) is in the frozen soil layer (13), and it is above freezing whether the interior temperature of pipe can remain on, and is the key of dealing with problems.For this reason, since 2002, the inventor has done a large amount of experiment and has observed, test into the Kailu County, Tongliao City, Inner Mongolia Autonomous Region domestic; 43 ° of north latitude, 6 months warming phases, the lowest temperature-30 ℃; Average frozen soil layer reaches 1.45m, adopts the mode of guaranteeing the repair free of charge to select to be tried building 30 families, under the situation of maintaining secrecy, constructs; Employed member is standard sewer pipe PVC accessory, wherein outer comb (9) internal diameter 11cm, and elbow and threeway are all revised with existing standard spare and are formed.Different with the distance of building because of sink hole (10), angle of inclination 2-30 ° of outer comb (9) is many with 4-18 °, and the shortest observation period is 5 years.Experimental result: do not find to freeze stifled phenomenon.Reach 60% and effluxed the pipe plugging rate in 5 years with regional resident's sewer pipeline of building up to 90%, twice above mediation rate, turnover rate reaches 40%.Explain that present technique is practicable.The anti-blocking reason of analyzing present technique is: because the underground temperature in indoor air temperature and the sink hole constantly carries out interchange of heat with the interior air of outer comb (9); Make and formed the microclimate that is higher than freezing point in the pipe; The souring of high-rise in addition water ability ice-formation condition can't occur in the pipe.
State on the implementation on the basis of technical scheme, also part indoor drainage pipeline is improved, the comb (4) that indoor horizontal is installed changes into tilting to install.Like Fig. 1,2, shown in 3, one section vertical comb (4) is arranged below the water consumption device (5), then through an elbow (6) to a lateral buckling, insert main comb (3) again.The angle β of the axis of the import (14) of the elbow here (6) and the axis of outlet (15) can be by 91-95 ° greater than 90 °, and per 1 ° of a kind of product forms serial connector.Because the many external diameters less than main comb (3) of the external diameter of a comb (4), the reducing bend (16) that needs shop drawings 4 to be introduced can better be satisfied the demand.Such pipeline, internal resistance significantly reduces, and the water loss of energy significantly reduces, and the souring of high-rise water ability is particularly outstanding, to the unimpeded certain function that played of whole sewer pipe.
