Abstract
The invention discloses an inspection well capable of performing reliable sealing of a branch pipe. The inspection well comprises an inspection well chamber. A well chamber opening for the branch pipe to be inserted and matched is formed in the side wall of the inspection well chamber. An annular umbrella-shaped sealing ring surrounding the inner wall of the well chamber opening by a circle is arranged on the well chamber opening. The end, far away from the inner wall of the well chamber opening, of the annular umbrella-shaped sealing ring is provided with a left sealing lug and a right sealing lug. Due to the fact that the annular umbrella-shaped sealing ring is arranged on the well chamber opening of the inspection well, after the branch pipe is installed, the annular umbrella-shaped sealing ring inclines to one side under extrusion of the branch pipe, the sealing lugs on the two sides of the annular umbrella-shaped sealing ring act on the inner wall of the well chamber opening and the outer wall of the branch pipe respectively, two-way sealing is achieved, a good sealing effect can be achieved from both the inner side and the outer side of the inspection well, and therefore the problem that the joint of the inspection well and the branch pipe is prone to leakage is solved; and meanwhile, plugging operation does not need to be performed on an installing site, on-site fast construction of the inspection well is better facilitated, and sealing quality is guaranteed.
Description
Technical field
The invention belongs to manhole manufacturing technology field, be specifically related to a kind of manhole and production technology thereof of reliably propping up the seal of tube.
Background technology
The fields such as the communications cable, electric power cable, plumbing and other infrastructure constructions, all indispensable equipment of manhole, its maintenance for pipeline and medium thereof is all extremely important.Existing manhole is by well room mostly, pit shaft, closing in circle and adjusting ring are formed, current urban road bottom need bury rainwater underground, sewage, the various pipelines such as water supply, surface course is just provided with corresponding manhole, and connection between manhole and Inlet and outlet water arm whether sealing relationship the safety of circulates, connection between conventional manhole and arm comprises and adopts gluing mode, by direct for arm fill-in well room opening, make to stick with glue and connect, though this kind of mode can firmly connect for the moment, but symmetrical backfill can not can affect glue and come unstuck in backfill process, thus cause seepage leakage phenomenon, also have in addition to adopt and adopt cement mortar or polyurethane cement mortar filleting at well room opening part and arm, one is need extra site operation, both bothered and again reduced installation effectiveness, two is that it very easily to leak at this link position place by site operation ambient influnence, thus causes seepage leakage phenomenon.
Summary of the invention

Detailed description of the invention
Below in conjunction with the accompanying drawings and the specific embodiments the present invention is described in further detail.
As shown in Figure 1, a kind of manhole reliably propping up the seal of tube, comprises manhole room 1, and described manhole room 1 sidewall is provided with the well room opening 2 coordinated for arm 4 grafting.As shown in Fig. 2, Fig. 3, Fig. 4 and Fig. 5, described well room opening 2 is provided with around its inwall ring-type umbrella sealing circle 3 of a week, ring-type umbrella sealing circle 3 is the annular special circle mated with described well room opening 2, and on its pre-buried inwall being arranged on described well room opening 2, ring-type umbrella sealing circle 3 has two, left and right sealing ear 31 away from one end of described well room opening 2 inwall, sealing ear 31 struts shape for both sides, and in beveled structure, its distraction angle is acute angle.
Because the present invention is provided with ring-type umbrella sealing circle 3 in opening 2 position, well room of manhole, after installing arm 4, under arm 4 extrudes, make ring-type umbrella sealing circle 3 to lopsidedness, the sealing ear 31 of such ring-type umbrella sealing circle 3 side opens and touch arm 4 outer wall, form leather cup structure, in self sealss state, (hydraulic pressure effect is larger, seal tighter), sealing is formed to well outdoor underground water and arm 4 wall, underground water is avoided to enter well room, the umbrella point of ring-type umbrella sealing circle 3 also touch arm 4 outer wall at opposite side on the other hand, form leather cup structure, in self sealss state, sealing is formed to the media such as the sewage of well chamber interior and arm 4 tube wall, well room medium is avoided to enter well outdoor soil, achieve two way seal, namely no matter be inside manhole or outside it, all can reach good sealing effectiveness, thus efficiently solve the problem that manhole and arm 4 junction easy to leak leak, simultaneously without the need to carrying out construction plugging operations in erecting bed, be more conducive to the on-the-spot rapid construction of manhole, and guarantee airtight quality.
Ring-type umbrella sealing circle 3 inside is provided with extruded hole 32 around it, is beneficial to the distortion of ring-type umbrella sealing circle 3, prevents sealing ring from dislocating under arm 4 extrudes.
Reliably prop up a production technology for the manhole of the seal of tube, it comprises the following steps:
A, precast inspection well are prepared burden: prepare burden by precast inspection well material requested and proportioning thereof;
B, installation check well mould: arrange working pit, working pit bottom surface arranges shaking platform, this shaking platform fixedly mounts mould assembling inside and outside manhole;
C, sealing ring mould is installed: according to well room opening 2 diameter of manhole and profile design processing ring-type umbrella sealing circle 3 and sealing ring mould, above-mentioned sealing ring mould is made up of matrix in docking and outer matrix, then ring-type umbrella sealing circle 3 is clamped between above-mentioned interior matrix and outer matrix, finally the integral sealing ring mould gripping ring-type umbrella sealing circle 3 is fixed on the outer mold of manhole; The well room opening 2 that namely shaping rear ring-type umbrella sealing circle 3 is inlaid in abnormity is inner, the present invention adopts the method for premounting sealing circle fixed mould, first pre-fix ring-type umbrella sealing circle 3, and then carry out process such as building, solve the problem that the ring-type umbrella sealing circle 3 of abnormity cannot be inlaid in opening 2 inside, well room of abnormity by the later stage well, without the need to later stage installation process, use more convenient;
D, to build: the manhole prepared batching is poured in the mould of manhole by running channel frock, and while building, control shaking platform vibration, and vibration compacting;
E, cure and demold: treat resin mixture curing and demolding;
F, Post RDBMS: the product after the demoulding is carried out Post RDBMS process to Post RDBMS station, Post RDBMS temperature is at 50 DEG C-100 DEG C, and rear curing time is at 2h-6h;
G, cleaning burr shaping: as required reconditioning processing is carried out to the end face of manhole and connecting portion.
The above, be only present pre-ferred embodiments, therefore can not limit scope of the invention process with this, and the equivalence namely done according to the present patent application the scope of the claims and description changes and modifies, and all should still remain within the scope of the patent.
