Description

Technical Field

[0001] The utility model belongs to the technical field of municipal engineering environmental protection, and in particular relates to a household inspection well structure used for drainage diversion transformation in narrow lanes. Background Art

[0002] At present, in order to implement various environmental protection policies promulgated and implemented by the state and realize full coverage, collection and treatment of sewage pipes, various types of projects such as rainwater and sewage diversion and source rectification have been implemented across the country. The purpose is to rectify the source drainage households with wrong connections and disorderly discharges, improve the diversion system, ensure that sewage does not enter the rainwater pipes, and rainwater does not enter the sewage pipes as much as possible, thereby improving the urban water environment.

[0003] The most critical part of rainwater and sewage separation is the transformation of the wrong mixed connection of the source drainage users. Generally, during the transformation, the source sewage is collected into the household well, and then the household well is connected in series through the household pipe and connected to the sewage main collection system around the building. Therefore, setting up the household well to divert the water from the source is very important for the realization of rainwater and sewage separation.

[0004] Source drainage users in cities mainly include residential areas, urban villages, public buildings, etc. The drainage conditions of each user are different, and the difficulty of transformation is also quite different. In particular, due to historical and personal land reasons, the reserved passages between buildings in urban villages are narrow, and the drainage outlets are limited. They can only be discharged through small drainage ditches or combined pipes reserved during construction. In addition, urban villages are mainly residential buildings for villagers, lacking unified planning, with concentrated and dense buildings and narrow alleys. When renovating the existing underground combined drainage system, there is not enough space to add new drainage pipes for source misconnection transformation, which makes it difficult to achieve true rainwater and sewage separation.

[0028] It should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected" and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integrally formed structure. For ordinary technicians in this field, the specific meanings of such terms in this patent can be understood according to specific circumstances.

[0029] like Figure 1-3As shown, this embodiment provides a household inspection well structure for drainage diversion reconstruction in narrow lanes, including a bottom plate 8, a well shaft, a lower sealing cover plate 3, two side walls 4, and an upper grille cover plate 1;

[0030] The wellbore is installed on the bottom plate 8, and a water inlet hole and a water outlet hole are arranged on the side wall of the wellbore, and the sealing cover of the lower sealing cover plate 3 is arranged at the top opening of the wellbore. The water inlet hole and the water outlet hole are used to connect with the household pipe, and a connection hole is reserved on the side wall of the wellbore for the access of the sewage outlet pipe, so that the user sewage can be connected to the household well through the building sewage riser or branch pipe, so that the user sewage can be discharged through the household pipe after entering the wellbore through the sewage riser or branch pipe.

[0031] The shaft has a rectangular cross-section. The shaft is composed of two first side walls and two second side walls. The first side wall is parallel to the side wall of the drainage ditch 10, and the second side wall is perpendicular to the first side wall. The two side walls 4 are respectively installed at the top of the two first side walls, and the side walls 4 are parallel to the first side walls. The upper grille cover plate 1 is covered on the top of the side wall 4 through the cover plate support 2. The upper grille cover plate 1, the side wall 4, and the lower sealing cover plate 3 together form a cover plate ditch connected to the drainage ditch 10 to form an upper rainwater discharge channel. For example, Figure 1 As shown, the left and right ends of the side wall 4 are respectively connected to the side walls of the drainage ditch 10 on both sides, and the left and right ends of the lower sealing cover plate 3 are respectively connected to the inner bottom surface of the drainage ditch 10 on both sides, so that the cover plate ditch can form a continuous drainage small square ditch together with the drainage ditch 10 on both sides. In addition, the setting of the upper grille cover plate 1 can meet the needs of pedestrians or vehicles.

[0032] Therefore, the household inspection well structure provided in this embodiment can restore the upper part of the household inspection well to a small square drainage ditch to discharge rainwater on both sides of the alley, and the lower part to a sewage household inspection well structure, forming a double-layer drainage channel, achieving the effect of rainwater and sewage diversion, so that all sewage is collected and rainwater is prevented from entering the sewage system as much as possible, effectively solving the problem of diversion and reconstruction of narrow alleys.

An inverted L-shaped groove is provided at the junction of the inner bottom surface of the drainage ditch 10 and the cover plate groove, and the lower sealing cover plate 3 is fixed with a lap plate 13 adapted to the groove, and the lap plate 13 is embedded in the groove. A sealing strip is provided between the lap plate 13 and the groove. On the one hand, the stability of the lower sealing cover plate 3 can be enhanced, and on the other hand, the sealing of the junction between the lower sealing cover plate 3 and the drainage ditch 10 on both sides can be improved.

[0035] In this embodiment, a heel plate is fixed on the outer side of the side wall 4. The heel plate can ensure the stability of the upper cover plate groove.

[0036] In this embodiment, the wellbore includes a bottom wellbore 7, a wellbore adjusting block 6 installed on the bottom wellbore 7, and an upper wellbore 5 installed on the wellbore adjusting block 6. A first limit block is fixed circumferentially at the top end of the bottom wellbore 7, a first limit groove matched with the first limit block is provided at the bottom of the wellbore adjusting block 6, and the first limit block is embedded in the first limit groove.

[0037] The height of the shaft adjustment block can be adjusted according to the buried depth of the household well to meet the requirements of different designed buried depths of the household well. At the same time, the shaft adjustment block has reserved connection holes for the access of sewage outlet pipes on both sides, and different adjustment shaft blocks can be prefabricated to meet the requirements. The cooperation between the first limit block and the first limit groove, and the cooperation between the second limit block and the second limit groove can improve the stability and convenience of the shaft assembly.

[0038] In addition, a third stopper adapted to the shaft is fixed to the top of the bottom plate 8 along the circumferential direction. The third stopper can improve the stability and convenience of the bottom shaft 7 during installation.

[0039] A fourth limiting groove is provided at the bottom of the side wall 4, and a fourth limiting block adapted to the fourth limiting groove is fixed at the top of the shaft. The cooperation between the fourth limiting block and the fourth limiting groove can improve the stability and convenience of the side wall 4 during installation.
