Description

TECHNICAL FIELD

[0001] The present application relates to the field of drainage engineering, in particular to a drainage maintenance structure. BACKGROUND

[0002] Drainage engineering refers to the engineering of collecting and discharging human domestic sewage and various waste water in production, excess surface water and underground water (lowering the underground water level). Drainage pipeline is the most important part of drainage engineering. Drainage pipeline is generally embedded underground to form a pipe network, thereby realizing the function of drainage. Since the pipeline is embedded underground for a long time, it is necessary to set up a maintenance well for maintenance personnel to descend for later maintenance of the pipeline.

[0003] At present, the wellhead of the maintenance well is usually covered by a well cover. When the pipeline needs to be maintained, the maintenance personnel opens the well cover and then descends through the maintenance well to the pipeline embedding position for work. However, the existing well cover is directly buckled on the wellhead, and the well cover is often lost, causing the wellhead to be open and having a large safety hazard. CONTENT OF THE UTILITY MODEL

The maintenance well 1 is made of reinforced concrete, and the bottom of the maintenance well 1 is poured with the concrete cushion 10. The concrete cushion 10 enhances the flatness and structural strength of the bottom foundation of the maintenance well 1, and improves the stability of the structure of the maintenance well 1. The reinforced concrete structure has good seismic resistance, corrosion resistance, bearing capacity and stability, so that the maintenance well 1 has good stability and structural strength.

[0033] With reference to Figure 1 , Figure 2 A climbing ladder 11 is installed on the sidewall of the maintenance well 1 and extends from the well mouth to the well bottom of the maintenance well 1. When the staff go up and down the maintenance well 1, the climbing ladder 11 provides a channel for the staff to go up and down, improving the convenience and safety of the staff going up and down the maintenance well 1.

[0034] With reference to Figure 1 , Figure 2 A U-shaped water flow groove 9 is formed in the maintenance well 1 by pouring concrete, and the drainage pipe 2 is connected and installed on the maintenance well 1, and the connection part of the drainage pipe 2 and the maintenance well 1 is embedded in the water flow groove 9, and the drainage pipe 2 is connected with the water flow groove 9.

[0035] The water flow groove 9 abuts against the outer wall of the drainage pipe 2, thereby positioning the drainage pipe 2 and improving the stability of the drainage pipe 2 in the maintenance well 1. Meanwhile, the water flow groove 9 can also guide the water to be discharged into the drainage pipe 2, improve the flow of water into the drainage pipe 2, reduce the accumulation in the maintenance well 1, and reduce the influence on drainage.

[0036] With reference to Figure 1 , Figure 2 The post-poured beam 8 is embedded on the well mouth of the maintenance well 1, and the well base 3 is embedded on the post-poured beam 8. In this embodiment, the post-poured beam 8 is a reinforced concrete beam. The staff first positions the well base 3 on the steel bars of the post-poured beam 8, and then pours concrete, so as to embed the well base 3 in the post-poured beam 8, improving the stability of the well base 3 at the well mouth.

[0037] With reference to Figure 1 , Figure 3The well lid 4 is buckled on the well base 3, a side wall of the well lid 4 is provided with a containing groove, the anti-dropping block 5 is slidingly inserted into the containing groove of the side wall of the well lid 4, and the well base 3 is provided with a limiting groove 31 on a side close to the well lid 4 in a circumferential direction for clamping the anti-dropping block 5; the control mechanism 6 is installed on the well lid 4, and the control mechanism 6 is used to drive the anti-dropping block 5 to extend out of the containing groove or retract into the containing groove. The control mechanism 6 comprises an anti-dropping spring 61, a cover plate 62, a winding shaft 63 and a pull rope 64. One end of the anti-dropping spring 61 is installed on the side wall of the containing groove, and the other end of the anti-dropping spring 61 is installed on the anti-dropping block 5. The anti-dropping spring 61 always has a tendency to drive the anti-dropping block 5 to slide in a direction away from the well lid 4. In this embodiment, the anti-dropping block 5 is provided with an arc surface on a side away from the anti-dropping spring 61 and close to the drainpipe 2, so that when the staff member moves the well lid 4 to be buckled on the well base 3, the arc surface on the anti-dropping block 5 abuts against the well base 3, and the well base 3 can press the anti-dropping block 5 into the containing groove, thereby improving the convenience of the staff member in buckling the well lid 4 on the well base 3.

[0038] With reference to Figure 1 , Figure 3 An operation groove 41 is formed on the well lid 4, and the cover plate 62 is hingedly installed on the well lid 4 and used to close the operation groove 41. A lock 7 is installed on the cover plate 62 and used to lock the cover plate 62 on the well lid 4. In this embodiment, the lock 7 is a cylindrical lock. After the staff member buckles the cover plate 62 on the well lid 4 to close the operation groove 41, the cover plate 62 can be locked in a state of closing the operation groove 41 by the lock 7, thereby improving the stability of the cover plate 62 on the well lid 4.

[0039] With reference to Figure 1 , Figure 3 The winding shaft 63 is rotatably installed on the bottom wall of the operation groove 41, one end of the pull rope 64 is wound on the winding shaft 63, and the other end of the pull rope 64 extends into the containing groove and is connected with the anti-dropping block 5. The staff member rotates the winding shaft 63, so that the winding shaft 63 drives the pull rope 64 to be wound on the winding shaft 63, and the pull rope 64 can pull the anti-dropping block 5 to slide into the containing groove. The staff member releases the winding shaft 63, and the anti-dropping spring 61 drives the anti-dropping block 5 to slide in a direction away from the well lid 4. During the sliding process, the anti-dropping block 5 pulls the pull rope 64 to make the pull rope 64 be unwound from the winding shaft 63, and the anti-dropping block 5 can extend out of the containing groove to the side wall of the well lid 4.

[0040] The implementation principle of the drainage maintenance structure in the embodiment of the application is as follows: when the drainage pipe 2 needs to be maintained, the worker first opens the lock 7 on the cover plate 62, then opens the cover plate 62, twists the winding shaft 63, and makes the pull rope 64 pull the anti-disengagement block 5 into the accommodating groove, so that the well lid 4 can be opened, then the extended crawling ladder 11 enters the maintenance well 1, after the maintenance is completed, the worker moves the well lid 4 to be buckled to the well seat 3, the anti-disengagement block 5 is accommodated into the accommodating groove under the abutting action of the well seat 3, when the well lid 4 is buckled to the well seat 3, the anti-disengagement block 5 is opposite to the limiting groove 31, the anti-disengagement spring 61 can drive the anti-disengagement block 5 to slide into the limiting groove 31, the anti-disengagement block 5 abuts against the side wall of the limiting groove 31, so that the well lid 4 and the well seat 3 can be separated, then the worker covers the cover plate 62 and locks the cover plate 62, the stability of the well lid 4 on the well seat 3 is effectively improved, and the problem that the well lid 4 of the maintenance well 1 is easy to be lost and has a safety hazard is improved.
