Detailed Description

In order to make the above objects, features and advantages of the present invention more comprehensible, the present invention is described in detail with reference to the accompanying drawings and the detailed description.

As shown in fig. 1, the plastic inspection well of the present embodiment includes a well base 1, a shaft 2 is disposed on the well base 1, at least two branch pipes 3 communicated with the shaft 2 are disposed on the side wall of the shaft 2, wherein: at least one branch pipe 3 is connected with a bent pipe 4.

As shown in fig. 2 to 3, the elbow pipe 4 includes a first pipe portion 41 and a second pipe portion 42, the first pipe portion 41 and the second pipe portion 42 forming an angle of 45 °, the outer diameter of the first pipe portion 41 matching the inner diameter of the branch pipe 3, and the outer diameter of the second pipe portion 42 matching the inner diameter of the first pipe portion 41.

In the embodiment of fig. 1, only one elbow 4 is connected to the branch pipe 3, a first pipe portion 41 of the elbow 4 is inserted into the branch pipe 3, and a second pipe portion 42 of the elbow 4 is a free pipe portion for connecting an external pipeline.

In the first embodiment shown in fig. 1, the second tubular section 42 is angled at 45 ° to the wellbore 2, i.e. in this embodiment the branch 3 is angled at 45 ° to the pipe.

In other embodiments, the drop height between the branch pipe 3 and the pipeline is large, so that a larger number of elbows 4 may need to be arranged. Thus, optionally, at least two elbows 4 are connected to the branch 3 in succession, wherein: the first pipe portion 41 of the elbow pipe 4 at the foremost end connected to the branch pipe 3 is penetrated into the branch pipe 3; the first pipe portions 41 of the remaining bent pipes 4 are fitted over the second pipe portions 42 of the preceding bent pipe 4. The second pipe portion 42 of the endmost elbow 4 is a free pipe section which is used for connecting external pipes.

In a second embodiment, as shown in fig. 4, the wellbore 2 is arranged in a vertical direction with the opening of the wellbore 2 facing upwards. Two elbows 4 are connected to the branch 3 in sequence, and a second pipe section 42 at the end elbow 4 is parallel to the wellbore 2. In this embodiment, the branch pipe 3 can be obliquely inserted at 90 degrees into the pipeline, and the fall between the branch pipe 3 and the pipeline can be compensated.

In a third embodiment, as shown in fig. 5, the wellbore 2 is arranged in a vertical direction with the opening of the wellbore 2 facing upwards. The branch pipe 3 is sequentially connected with three bent pipes 4, and a second pipe part 42 of the bent pipe 4 at the tail end forms an included angle of 45 degrees with the shaft 2. In this embodiment the branch 3 is able to be angled at 45 ° to the pipe and to compensate for the large fall between the branch 3 and the pipe, which is greater than in the second embodiment.

In the fourth embodiment, as shown in fig. 6, the shaft 2 is disposed in a vertical direction with the opening of the shaft 2 upward. Four elbows 4 are connected to the branch 3 in sequence, and the second pipe portion 42 of the elbow 4 at the end is perpendicular to the shaft 2. This embodiment is able to compensate for a larger drop between the branch 3 and the pipe than in the third embodiment.

Of course, through the return bend 4 that sets up other quantity and the angle of installation of adjusting each return bend 4, the utility model discloses can realize being located the not connection of the pipeline of equidirectional, position with other.

Optionally, in order to ensure the supporting performance of the shaft 2, as shown in fig. 1, a grid-shaped supporting rib 5 is arranged on the outer wall of the shaft 2.

In other application scenarios, the pipes to be connected are at the same height as the branches 3 of the plastic manhole (i.e. there is no drop), but there is a certain distance or angle of inclination between the pipes to be connected and the branches 3. As shown in fig. 7 to 8, in the fifth to eighth embodiments, the connection with the pipeline of the present invention can be realized in these situations by adjusting the number and the installation angle of the bent pipes 4 and making each bent pipe 4 and the branch pipe 3 at the same installation height.

Optionally, in order to improve the sealing performance between adjacent bent pipes 4 and between the bent pipe 4 and the branch pipe 3, water leakage at the joint is prevented. As shown in fig. 1, the outer walls of the first pipe portion 41 and the second pipe portion 42 are provided with a plurality of sealing ribs 43. Such as: when the first pipe portion 41 of the elbow 4 is inserted into the branch pipe 3, the sealing ribs 43 on the first pipe portion 41 are abutted against the inner wall of the branch pipe 3 to form a plurality of sealing contact rings.

The invention has been described above with a certain degree of particularity and detail. It will be understood by those of ordinary skill in the art that the description of the embodiments is merely exemplary and that all changes that may be made without departing from the true spirit and scope of the present invention are intended to be within the scope of the present invention.
