[0033] Embodiment

[0034] Reference Figs. 1-3 For one embodiment of the present application, a manhole base capable of preventing stress cracking is provided, comprising: a whole unit 100, a sinking prevention unit 200, a supporting unit 300 and a prevention detection mechanism 400;

[0035] The whole unit 100 comprises a base body 101 and two cylinders 102 fixedly connected to the side wall of the base body 101.

[0036] The sinking prevention unit 200 comprises a plurality of fixing bases 201 fixedly connected to the side wall of the base body 101, and each fixing base 201 is provided with a horizontal plate 202 fixed by bolts on one side.

[0037] The supporting unit 300 comprises two groups of supporting assemblies 301 arranged in the base body 101, and each group of supporting assemblies 301 is used for horizontally supporting the inner cavity of the base body 101.

[0038] The prevention detection mechanism 400 is arranged in the base body 101 and is used for detecting the inclination degree of the base body 101.

[0039] Specifically, the top of each horizontal plate 202 is fixedly connected with a compression-resistant plate 203, the top of each compression-resistant plate 203 is semicircularly protruded, the supporting assembly 301 comprises a pair of concave plates 3011 fixed to the inner wall of the base body 101, and the concave surfaces of adjacent two concave plates 3011 are jointly and slidably provided with an I-beam 3012, and the two sides of each I-beam 3012 are attached to the inner wall of the base body 101.

[0040] The well seat body 101 is buried underground, and the opening at the top of the well seat body 101 can be equipped with a well cover. The horizontal plate 202 is T-shaped, and is used to laterally support the inner cavity of the side wall of the well seat body 101. When the well seat body 101 settles, the well seat body 101 is limited by the horizontal plate 202, so that it is difficult to settle greatly. The horizontal plate 202 reduces the settlement displacement of the well seat body 101. The compression plate 203 can uniformly disperse the pressure of the earth on the horizontal plate 202 through the semicircular protrusion, so as to improve the bearing and compression resistance of the top of the horizontal plate 202 through the compression plate 203. The horizontal plate 202 can be disassembled and replaced by bolts after being damaged.

[0041] The number of support assemblies 301 can be increased or decreased according to the height of the well seat body 101. The I-beam 3012 can be removed from the concave plate 3011 so that workers can enter the well seat body 101 for inspection. Adjacent two I-beams 3012 are cross-distributed. The I-beam 3012 is used to provide lateral support force to the well seat body 101. When the pressure of the ground acts on the side wall of the well seat body 101, the side wall of the well seat body 101 can be supported by the I-beam 3012 to prevent the well seat body 101 from cracking due to excessive pressure. The inclination degree of the well seat body 101 can be detected by the prevention and detection mechanism 400, so that the inclined well seat body 101 can be corrected in time to prevent the well seat body 101 from cracking due to uneven stress.

[0042] In addition, a space is left between the two I-beams 3012. The top of each I-beam 3012 is fixedly connected with a inverted U-shaped rod 302. The interiors of the two cylinders 102 are provided with three-pronged plates 303. The ends of each three-pronged plate 303 are fixedly connected with a support plate 304. Each support plate 304 is fixed to the inner wall of the corresponding cylinder 102.

[0043] The inverted U-shaped rod 302 facilitates workers to lift the I-beam 3012 upward, so that the I-beam 3012 can be taken out of the well seat body 101, so that workers can pass through the well seat body 101 and perform inspection. The support plate 304 is used to increase the contact surface of the three-pronged plate 303 and the cylinder 102. When the fillers such as soil and concrete are filled above the cylinder 102, the three-pronged plate 303 can support the cylinder 102 to avoid cracking of the top of the cylinder 102 due to excessive pressure.

[0044] Further, the prevention and detection mechanism 400 comprises a protection box 401 fixedly connected to the inner wall of the well seat body 101. The bottom of the inner cavity of the protection box 401 is fixedly connected with an inclination sensor 402.

[0045] The protection box 401 is used to prevent rain and soil from affecting the operation of the tilt sensor 402, which is a sensor for measuring the inclination angle of an object relative to the horizontal plane. It calculates the inclination angle by measuring the component of gravitational acceleration on the sensor sensitive axis and outputs it to the network or display screen through the communication unit. When the well seat body 101 is tilted, the tilt sensor 402 can detect the change in the tilt of the well seat body 101 and transmit the tilt information to the worker through the internal communication unit, so that the worker can correct the well seat body 101 in time. The use of the tilt sensor 402 can prevent the well seat body 101 from cracking due to stress caused by tilting.

[0046] Further, the inner wall of the well seat body 101 is fixedly connected with a plurality of lifting rings 103, which are located in the same plane and are equally distributed in a ring shape. The top and bottom of the well seat body 101 are fixedly sleeved with reinforcing rings 104, and the ends of the two cylinders 102 are fixedly sleeved with reinforcing rings 105.

[0047] The lifting ring 103 is used to lift the well seat body 101 to move the well seat body 101. The reinforcing ring 104 is used to reinforce the top and bottom of the well seat body 101 to increase the strength of the top and bottom of the well seat body 101. The reinforcing ring 105 is used to strengthen the strength of the end of the cylinder 102 to prevent cracking due to excessive stress.

[0048] During use, the well seat body 101 can be lifted by the lifting ring 103 to be buried under the ground. The horizontal plate 202 can support the inner cavity of the side wall of the well seat body 101 horizontally. The well seat body 101 is difficult to settle greatly through the horizontal plate 202. The horizontal plate 202 can be disassembled and replaced after being damaged. The I-beam 3012 can support the side wall of the inner cavity of the well seat body 101 to prevent cracking of the well seat body 101 due to excessive pressure. The inverted U-shaped rod 302 can take out the I-beam 3012 from the concave plate 3011 to facilitate the worker to pass through the well seat body 101 and check;

[0049] When the fillers such as soil and concrete are filled above the cylinder 102, the three-pronged plate 303 can support the cylinder 102 to avoid cracking of the top of the cylinder 102 due to excessive pressure. When the well seat body 101 is tilted, the tilt sensor 402 can detect the change in the tilt of the well seat body 101 and transmit the tilt information to the worker through the internal communication unit, so that the worker can correct the well seat body 101 in time. The use of the tilt sensor 402 can prevent the well seat body 101 from cracking due to stress caused by tilting.

[0050] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present application and are not limiting. Although the present application has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the technical solutions of the present application can be modified or replaced equivalently without departing from the spirit and scope of the technical solutions of the present application, and they should be covered in the scope of the claims of the present application.
