A limiting ring for anti-settlement manhole covers

Abstract

This utility model discloses a limiting manhole ring for anti-settlement manhole covers, including a base layer, a ground layer, and a limiting mechanism. The ground layer is laid on top of the base layer, and the limiting mechanism is set inside the base layer and the ground layer. The limiting mechanism includes a well hole, an insertion hole, a support ring, a reinforcing bar, a concrete manhole ring, and a ring-shaped reinforcing bar. The well hole is opened inside the base layer, and the top of the well hole penetrates the ground layer. The insertion hole is opened vertically on the outer periphery of the well hole inside the ground layer, and the bottom of the insertion hole extends into the base layer. When the manhole ring and the manhole cover are under pressure, the pressure at the pressure point can be dispersed and transmitted to the interior of the base layer because the position of the support ring is fixed. At the same time, because the reinforcing bar is embedded in the concrete, its position is fixed, and the support ring will not tilt or settle, thereby improving the stability of the concrete manhole ring. It can still avoid settlement problems after long-term pressure and maintain the smoothness of the road surface.

Description

Technical Field

[0001] This utility model relates to the field of manhole cover assembly technology, and in particular to a limiting manhole ring for anti-settlement manhole covers. Background Technology

[0002] Manhole covers are covers placed over various manholes to seal them. They are usually installed in conjunction with manhole rings and inside the rings. Manhole rings are ring-shaped components used to protect the manhole and support the manhole. They are usually made of reinforced concrete or precast steel and are widely used.

[0003] Existing manhole ring structures have the following drawbacks in use: manhole rings are usually installed in conjunction with manhole covers, and the manhole rings are usually cast directly from reinforced concrete at the top of the manhole opening. During long-term use, the continuous compression from the road surface can cause deformation of the manhole ring installation position, which in turn leads to the settlement of the manhole ring and the manhole cover, affecting the smoothness of the road surface. To address this, we propose a limiting manhole ring for anti-settlement manhole covers. Utility Model Content

[0004] The main purpose of this utility model is to provide a limiting well ring for anti-settlement manhole covers. Through the limiting mechanism, new components are used to further limit and fix the well ring structure, thereby preventing its settlement and effectively solving the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A limiting ring for anti-settlement manhole covers includes a base layer, a ground layer, and a limiting mechanism. The ground layer is laid on top of the base layer, and the limiting mechanism is installed inside the base layer and the ground layer. The limiting mechanism includes a well hole, an insertion hole, a support ring, a reinforcing bar, a concrete well ring, and a ring-shaped reinforcing bar. The well hole is opened inside the base layer, and the top of the well hole penetrates the ground layer. The insertion hole is opened vertically on the outer periphery of the well hole inside the ground layer, and the bottom of the insertion hole extends into the base layer. The support ring is installed at the top of the well hole inside the ground layer, and a reinforcing bar is welded to the bottom of the support ring. The concrete well ring is installed at the top of the well hole inside the ground layer, and a ring-shaped reinforcing bar is embedded inside the concrete well ring.

[0007] Furthermore, it also includes an auxiliary mechanism. An auxiliary mechanism is provided inside the ground layer. The auxiliary mechanism includes slots and limiting ribs. Slots are horizontally opened at the top of the well in the ground layer, and limiting ribs are inserted into each slot. Slots extending into the ground layer are opened laterally at the opening of the well, and then limiting ribs are inserted into the slots. The ends of the limiting ribs extend to the outside of the slots. When the ring support structure is installed in place, its outer periphery fits exactly with the end of the limiting rib, and the connection is welded and fixed together. Through the cooperation of the limiting rib structure and the slot structure, the force on the well ring and the well cover can be distributed to different positions inside the ground layer, further improving the stability of the well ring position.

[0008] Furthermore, the insertion rod is aligned with the insertion hole and inserted into the insertion hole; when the support ring is laid, the insertion rod structure at its bottom end is aligned with the insertion hole and inserted to fix the insertion rod to the ground layer.

[0009] Furthermore, a connecting rib is welded to the top of the support ring, and the top of the connecting rib is welded to the surface of the annular reinforcing bar. After the support ring is fixed, the annular reinforcing bar is constructed. After the construction is completed, the annular reinforcing bar and the connecting rib are welded together to improve the connection stability.

[0010] Furthermore, the limiting rib is welded to the surface of the support ring at the end facing the well hole; by welding and fixing the end of the limiting rib to the support ring, the structural strength and stability of the connection are improved.

[0011] Compared with the prior art, this utility model has the following beneficial effects: After the well hole construction is completed, an insertion hole is opened at the top of the well hole at the outer perimeter of the well hole. The insertion hole is opened vertically and extends into the foundation. A connecting component is made, and connecting bars and insertion bars are welded to the upper and lower ends of the support ring to form a connector. During construction, concrete is first poured into the insertion hole, and then the insertion bars are inserted into the insertion hole. The overflowing concrete is cleaned up. After the concrete solidifies, the position of the support ring is fixed. Then, the ring steel bar is tied at the top of the support ring and welded to the connection with the connecting bar. After welding, concrete is poured to form a complete concrete well ring structure. The support ring is used as a connector to connect the concrete well ring and the installation surface, improving its stability. The well cover is installed inside the concrete well ring. When the manhole ring and cover are under pressure, the fixed position of the support ring can disperse and transfer the pressure to the ground layer. Simultaneously, because the reinforcing bars are embedded in the concrete and their positions are fixed, the support ring will not tilt or settle, thus improving the stability of the concrete manhole ring. Even after long-term pressure, it can still avoid settlement and maintain road surface smoothness. A slot extending into the ground layer is laterally opened at the manhole opening, and a limiting bar is inserted into the slot, with its end extending outside the slot. When the support ring structure is installed, its outer circumference fits perfectly with the end of the limiting bar, and the connection is welded together. Through the cooperation of the limiting bar structure and the slot structure, the force on the manhole ring and cover can be dispersed to different locations within the ground layer, further improving the stability of the manhole ring position.

[0017] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0018] like Figure 1-4 As shown, a limiting ring for an anti-settlement manhole cover includes a base layer 1, a ground layer 2, and a limiting mechanism 3. The ground layer 2 is laid on top of the base layer 1, and the limiting mechanism 3 is installed inside the base layer 1 and the ground layer 2. The limiting mechanism 3 includes a well hole 301, an insertion hole 302, a support ring 303, a reinforcing bar 304, a concrete well ring 306, and a ring-shaped reinforcing bar 307. The well hole 301 is opened inside the base layer 1, and the top of the well hole 301 penetrates the ground layer 2. The insertion hole 302 is opened vertically on the outer periphery of the well hole 301 inside the ground layer 2, and the bottom of the insertion hole 302 extends into the base layer 1. The support ring 303 is installed on the top of the well hole 301 inside the ground layer 2, and the reinforcing bar 304 is welded to the bottom of the support ring 303. The concrete well ring 306 is installed on the top of the well hole 301 inside the ground layer 2, and the ring-shaped reinforcing bar 307 is embedded inside the concrete well ring 306.

[0019] The system also includes an auxiliary mechanism 4, which is installed inside the ground layer 2. The auxiliary mechanism 4 includes a slot 401 and a limiting rib 402. A slot 401 is horizontally opened at the top of the well 301 inside the ground layer 2, and a limiting rib 402 is inserted into each slot 401. A slot 401 extending into the ground layer 2 is opened laterally at the opening of the well 301, and then a limiting rib 402 is inserted into the slot 401. The end of the limiting rib 402 extends to the outside of the slot 401. When the support ring 303 structure is installed in place, its outer periphery fits exactly with the end of the limiting rib 402, and the connection is welded and fixed together. Through the cooperation of the limiting rib 402 structure and the slot 401 structure, the force on the well ring and the well cover can be distributed to different positions inside the ground layer 2, further improving the stability of the well ring position.

[0020] The insert 304 is aligned with the insertion hole 302 and inserted into the insertion hole 302. The top of the support ring 303 is welded with a connecting rib 305, and the top of the connecting rib 305 is welded to the surface of the annular steel bar 307. When the support ring 303 is laid, the structure of the insert rib 304 at its bottom end is aligned with the insertion hole 302 and inserted to fix the insert rib 304 to the base layer 1. After the support ring 303 is fixed, the annular steel bar 307 is constructed. After the construction is completed, the annular steel bar 307 and the connecting rib 305 are welded together to improve the connection stability.

[0021] The limiting rib 402 is welded to the surface of the support ring 303 at one end facing the well 301; by welding and fixing the end of the limiting rib 402 to the support ring 303, the structural strength and stability of the connection are improved.

[0022] It should be noted that this utility model is a limiting well ring for anti-settlement manhole covers. During construction, after the well hole 301 is constructed, an insertion hole 302 is opened at the top of the well hole 301 on its outer periphery. The insertion hole 302 is opened vertically and extends into the base layer 1. A connecting component is made. Connecting ribs 305 and insertion ribs 304 are welded to the upper and lower ends of the support ring 303 to form a connecting component. During construction, concrete is first poured into the insertion hole 302, and then the insertion ribs 304 are inserted into the insertion hole 302. The overflowing concrete is cleaned up. After the concrete solidifies, the position of the support ring 303 is fixed. Subsequently, a ring-shaped steel bar 307 is tied to the top of the support ring 303 and welded to the connection point between it and the connecting rib 305. After welding, concrete is poured to form a complete concrete well ring 306 structure. The support ring 303 is used as a connecting component to connect the concrete well ring 306 to the mounting surface to improve its stability. The manhole cover is installed on the concrete well ring 306. Inside the earthen well ring 306, when the well ring and well cover are under pressure, the pressure at the pressure point can be dispersed and transmitted to the interior of the ground layer 1 because the position of the supporting ring 303 is fixed. At the same time, because the reinforcing bar 304 is embedded in the concrete and its position is fixed, the supporting ring 303 will not tilt or settle, thereby improving the stability of the concrete well ring 306. It can still avoid settlement problems after long-term pressure and maintain the flatness of the road surface. A slot 401 extending into the ground layer 2 is opened laterally at the opening of the well hole 301. Then, a limiting bar 402 is inserted into the slot 401. The end of the limiting bar 402 extends to the outside of the slot 401. When the supporting ring 303 structure is installed in place, its outer periphery fits exactly with the end of the limiting bar 402, and the connection is welded and fixed together. Through the cooperation of the limiting bar 402 structure and the slot 401 structure, the force on the well ring and well cover can be dispersed to different positions inside the ground layer 2, further improving the stability of the well ring position.
