One to four pipeline gully detention grooves are arranged, the side wall of the pipeline gully detention body adopts a half-tenon supporting structure, the middle wall of the gully detention adopts a tenon supporting structure, and the pipeline gully detention is provided with one to four cover boards matched with the gully detention grooves. The utility model has the advantages that the structure is simple, the stress is even and reasonable, the installation is flexible and fast, and the use is convenient; rainwater can not easily infiltrate into the pipeline gully detention, and the cable groove laying construction is facilitated.
Description
Technical field
The utility model relates to a kind of precast concrete pipeline gully detention and cover plate.
Background technology
Cable trough that uses at present and cover plate prefabricated component have and water the cable trough of present situation as U-shaped at the scene; (as Fig. 7); in use there are following problem in this pipeline gully detention and cover plate: 1, between cover plate and the gully detention abutment wall vertical slit is arranged; rainwater is easy to conflux and penetrates into cable trough on the cover plate face; cause humidity and ponding in the pipeline gully detention, be unfavorable for the insulation and the protection of cable.2, between cover plate and the gully detention abutment wall vertical slit is arranged, in use the suffered soil pressure of gully detention body abutment wall can not be born and transmit to the cover plate horizontal direction, the independent soil pressure of all bearing of gully detention, and corresponding gully detention abutment wall and floor generally need thicker size, and need arrangement of reinforcement, material cost is higher.Also have a kind of cable trough and cover plate prefabricated component, (as shown in Figure 7) supporting surface of the left and right cell wall cover plate of conduit and door plate face all are projections, this projection pouring reinforcing bar is not in place or water bad, break projection during installation because of carelessness easily, vibrate big during use or collide and break projection easily, cover plate comes off easily, and lid is less than the cable groove.
The utility model content
The utility model is design in order to solve the problems of the technologies described above a kind of flexible for installation, quick, easy to use, is convenient to the precast concrete pipeline gully detention and the cover plate of quick cable groove laying construction.
The technical scheme that its technical problem that solves the utility model adopts is:
A kind of precast concrete pipeline gully detention and cover plate are made up of pipeline gully detention groove and cover plate; Described pipeline gully detention body abutment wall adopts half tenon type supporting structure, and the gully detention middle walls adopts tenon type supporting structure; Left and right and the middle abutment wall end face in conduit both sides is on same plane, and left and right abutment wall top braces is provided with an inclined-plane towards the conduit direction, gully detention middle walls tenon type supporting structure, and supporting surface is provided with an inclined-plane to both sides conduit direction; Described cover plate left and right is provided with the top support surface contact-making surface with the left and right abutment wall half tenon type of pipeline gully detention, be close to the inclined-plane that is provided with the left and right abutment wall half tenon type top support surface of pipeline gully detention at contact-making surface, left and right, middle contact-making surface of cover plate and inclined-plane and the left and right and middle abutment wall supporting surface of pipeline gully detention, inclined-plane are complementary.
The left and right abutment wall top braces of described pipeline gully detention is provided with an inclined-plane towards the conduit direction, and the angle that this inclined-plane becomes with horizontal plane is: the 20-70 degree; Gully detention middle walls tenon type supporting surface is provided with an inclined-plane to both sides conduit direction, and the angle that this inclined-plane becomes with horizontal plane is: the 20-70 degree.
Described pipeline gully detention can be provided with one to four conduit, and described cover plate is provided with and one to four cover plate that conduit is complementary of pipeline gully detention.
Compared with the prior art the utility model a kind of precast concrete pipeline gully detention and cover plate have following beneficial effect:
1, the slick and sly line style of conic section is adopted on empty surface in gully detention and the cover plate, and cover plate span direction is arch form structure, can make full use of concrete pressurized performance, increases the cover plate span ability simultaneously.The table transition circle is suitable in the gully detention cell body, and no dead angle makes its internal force distribution uniform.
2, in use, (limit) wall adopts tenon type (half tenon type) supporting structure in cover plate and the gully detention, cover plate and gully detention limit (in) the wall interlock is tight, rainwater is difficult to directly conflux by the horizontal gap of cover plate and gully detention body and infiltrates the pipeline gully detention, a spot of water also can flow into by the spilled water hole that the bottom of trench center is reserved in the bottom of trench infiltration sand, can keep dry in the gully detention; Cover plate and gully detention body wall can not produce the skew dislocation, and the cover plate installing and locating is convenient, easy, accurate.
3, when cover plate and gully detention wall bore service load separately, the interaction force that is produced between cover plate and the gully detention wall all improved the stressed of the other side, and corresponding minimizing the other side's internal force makes structure stress even, has prolonged the useful life of member.
4, cover plate and gully detention adopt mould mechanization streamline to produce, its efficient height, and steady quality is saved a large amount of templates and artificial simultaneously, has reduced the prefabricated place that the job site need be taken over for use.
5, because abutment wall and middle wall all have tenon type supporting constraint with cover plate, two and above trench cover when the disconnected row damage of adjacent cover plate, do not influence effective use of adjacent cover plate, adjacent pipeline of striding still can be effectively protected before replacing.
6, spilled water hole is located at the base plate middle part, and is strong from drainability, and outside not being exposed to, having avoided mouse to pierce and bitten pipeline in the gully detention broken.
7, the material of this gully detention and cover plate utility model adopts high strength fibre concrete new technology, has saved the consumption of reinforcing bar, and is all favourable to energy savings and protection environment.
