Examples
As shown in fig. 1 to 4, this embodiment provides a concrete prefabricated well with a hoop locking structure, including: the well seat 1 is provided with a plurality of interfaces 11 in a protruding mode in the circumferential direction, a positioning step 12 is arranged in the interfaces 11, and a sealing element 21 is arranged in the positioning step 12; a branch pipe 2 installed in the interface 11, wherein the branch pipe 2 is sleeved with the sealing element 21; and the anchor ear 3 is in sealing connection with the corresponding interface 11 through a fastener 31.
In this embodiment, the positioning step 12 extends inward from the outer edge of the interface 11, and has a width dimension D, so that the positioning step 12 has a limiting effect on the sealing element 21, thereby enhancing the sealing effect of the sealing element 21.
At the same time, the dimensions of the sealing element 21 are adapted to the dimensions of the positioning step 12, i.e. the width dimension of the sealing element 21 is preferably smaller than the width dimension of the positioning step 12, so that the remaining space can accommodate the edge portion of the anchor ear 3, so that it can press the sealing element 21.
Moreover, a plurality of mounting holes 13 are uniformly distributed on the circumferential edge of the connector 11, nuts or expansion screws are pre-buried in the mounting holes 13, so that the fastening of the fastening piece 31 is facilitated, the reliability of connection and fixation is improved, and the problem of soil pollution caused by sewage leakage due to sinking of the branch pipe 2 caused by soil settlement is solved.
In this embodiment, the anchor ear 3 includes two symmetrically disposed arc-shaped unit elements 32, two ends of the two arc-shaped unit elements 32 are fixedly connected through a locking member 33, the arc-shaped unit elements 32 include an arc-shaped hoop body 321, two ends of the arc-shaped hoop body 321 are respectively provided with a first connecting portion 322 parallel to the axis thereof, the outer side wall of the arc-shaped hoop body is provided with at least one second connecting portion 323 fixedly connected with the corresponding edge of the interface 11, when a plurality of second connecting portions 323 are present, preferably, a plurality of second connecting portions 323 are uniformly distributed on the outer side wall of the arc-shaped hoop body 321, a space L is reserved between the second connecting portions 323 and the inner side edge of the arc-shaped hoop body 321, the space L is smaller than the width dimension D of the positioning step 12, enough installation space is reserved for the sealing member 21, so that the sealing member 21 can be squeezed conveniently, and when the anchor ear 3 is locked by the fastener 31, the anchor ear 3 has a squeezing effect on the sealing member 21, and the sealing member 21 is further improved.
In addition, in this embodiment, the outer diameter of the anchor ear 3 is adapted to the inner diameter of the interface 11, so as to avoid the problem that the sealing effect of the sealing element 21 is poor due to the fact that the anchor ear 3 cannot press the sealing element 21 well due to the mismatching of the sizes of the anchor ear 3 and the interface 11.
The installation process of the embodiment is as follows: firstly, the sealing element 21 and the anchor ear 3 are respectively sleeved on the branch pipe 2 in sequence and are received in the insertion interface 11 together, so that the sealing element 21 is just clamped inside the positioning step 12, then the anchor ear 3 is fixedly connected with the well seat 1 by screwing the fastener 31 into the mounting hole 13, and at the moment, the edge part of the anchor ear 3 can continuously squeeze the sealing element 21 until the fastener 31 is completely fixed.
The foregoing description of the preferred embodiments of the utility model is not intended to be limiting, but rather is intended to cover all modifications, equivalents, and alternatives falling within the spirit and principles of the utility model.
