Description
Technical Field
[0001] The utility model relates to the technical field of drainage pipeline construction, in particular to a device for caulking construction of large-diameter drainage pipes. Background Art
[0002] Large-diameter drainage pipes mostly refer to pipes made of concrete with a diameter greater than or equal to 1.5m. They are often used for rainwater and sewage discharge on main roads to meet the needs of rapid discharge of large amounts of water.
[0003] Caulking of large-diameter sewer pipes is a sealing treatment technology for the joints of large-diameter sewer pipes or fine cracks in the pipe body, which aims to prevent leakage and ensure the tightness and long-term stability of the pipe system. This construction process is essential to maintain the efficient operation of urban drainage systems, especially in combating rainwater flooding and preventing groundwater pollution. During caulking, manual or mechanical injection equipment is required to evenly and continuously inject the caulking material into the crack until the material overflows from the other side or reaches the predetermined filling volume. For surface joints, it may be necessary to apply a layer of sealing paste or fit waterproof tape to ensure the sealing effect.
[0004] However, since the diameter of the large-diameter drainage pipe is large, a ladder needs to be set up to reach a higher place for construction. Currently, single-sided ladders are mostly used. Therefore, after completing the caulking of one side of a drainage pipe, the single-sided ladder needs to be moved to the other side; after completing the caulking of one drainage pipe, the ladder needs to be moved to another drainage pipe for caulking. However, such construction will result in low work efficiency. Utility Model Content
[0005] The purpose of the utility model is to solve the problem that in the prior art, during the caulking construction of large-diameter drainage pipes, a single-sided ladder is mostly used for up and down construction. After one construction is completed, it needs to be manually carried to the next construction site, resulting in low work efficiency. A device for the caulking construction of large-diameter drainage pipes is provided.
[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is:
[0007] A device for caulking large-diameter drainage pipes, comprising:
[0008] A ladder beam, wherein the ladder beam is used to be arranged outside the drainage pipe, and the legs of the ladder beam are used to be arranged on both sides of the drainage pipe respectively, and the ladder beam can move along the length direction of the drainage pipe;

[0010] The legs of the ladder beam are arranged on both sides of the drainage pipe, and the steps are spaced apart along the length of the ladder beam, so that the workers can directly climb the steps and go from one side of the drainage pipe to the other side along the ladder beam. Compared with the prior art using a single-sided ladder, after completing the construction of one side of a caulking, there is no need to move the ladder beam, and the workers can directly follow the ladder beam to the other side to start construction, which is conducive to improving work efficiency. Moreover, the ladder beam can be moved along the length of the drainage pipe. When the next caulking needs to be constructed, the ladder beam can be directly moved to the predetermined position without manual handling, which is convenient for operation and conducive to improving construction efficiency.
[0011] As a preferred solution of the utility model, the ladder beam is an arc-shaped component, and the shape of the ladder beam is adapted to the drainage pipe.

[0013] As a preferred solution of the utility model, the ladder beam is provided with a plurality of running devices, and the running devices are arranged between the ladder beam and the drainage pipe.
[0014] The walking device is arranged between the drainage pipe and the ladder beam, so when the arc-shaped member is moved, the stability of the arc-shaped member during movement can be ensured as much as possible.

[0016] The traveling device can move along the track, and the track is provided with a limit stopper, so that the traveling device will not deviate away from the track during movement, thereby preventing the ladder beam from rotating around the axis of the drainage pipe.
[0017] As a preferred solution of the utility model, a plurality of the walking devices are arranged at intervals along the length direction of the ladder beam, and the connection positions between the walking devices and the drainage pipe include the lower two sides and the top of the drainage pipe.
[0018] The lower sides and top of the drainage pipe are connected with walking devices, which can prevent the ladder beam from detaching from the drainage pipe as much as possible.
[0019] As a preferred solution of the utility model, both ends of the ladder beam can be removably provided with limiting members, and the limiting members can be respectively connected to the ladder beam and the ground below the drainage pipe, and the limiting members can limit the movement of the arc-shaped component along the circumferential and longitudinal directions of the drainage pipe.
[0020] Because the ladder beam is an arc-shaped component that is fitted onto the drainage pipe, it will rotate around the axis of the drainage pipe. One end of the limiter is connected to the ground, which can limit the rotation of the ladder beam and the movement of the ladder beam along the axis of the drainage pipe. During the construction process, move the ladder beam to the joint that needs to be constructed, install the limiter, and then proceed with the construction.

Compared with the prior art using a single-sided ladder, after completing the construction of one side of a caulking, there is no need to move the ladder beam, and the construction can be directly carried along the ladder beam to the other side, which is conducive to improving work efficiency. The ladder beam can also be moved along the length direction of the drainage pipe. When the next caulking needs to be constructed, the ladder beam is directly moved to a predetermined position without manual transportation, which is easy to operate and conducive to improving construction efficiency. This device solves the problem that in the prior art, during the caulking construction of large-diameter drainage pipes, a single-sided ladder is often used for up and down construction.

[0041] Example 1
[0042] A device for caulking large-diameter drainage pipes, comprising: a ladder beam 1, the ladder beam 1 is used to be arranged on the outside of the drainage pipe 4, the legs of the ladder beam 1 are used to be arranged on both sides of the drainage pipe 4 respectively, and the ladder beam 1 can move along the length direction of the drainage pipe 4; a plurality of pedals 3, the plurality of pedals 3 are arranged at intervals along the length direction of the ladder beam 1.
[0043] The legs of the ladder beam 1 are arranged on both sides of the drainage pipe 4, and the pedals 3 are spaced apart along the length direction of the ladder beam 1. Compared with the prior art using a single-sided ladder, after completing one side of a caulking, there is no need to move the ladder beam 1, and the construction can be directly carried out along the ladder beam 1 to the other side, which is conducive to improving work efficiency. The ladder beam 1 can be moved along the length direction of the drainage pipe 4. When the next caulking needs to be constructed, the ladder beam 1 can be directly moved to a predetermined position without manual handling, which is convenient for operation and conducive to improving construction efficiency.

This form of ladder beam 1 is easy to process.
[0052] Example 3
[0053] like Figure 3 and Figure 4 As shown, a device for caulking construction of large-diameter drainage pipes is different from Example 1 in that the limiter can also be replaced by a track 6. The outer wall of the drainage pipe 4 is provided with a plurality of tracks 6, and the spacing between two adjacent tracks 6 is equal to the spacing between two adjacent sets of running devices 2. The axis of the track 6 is parallel to the axis of the drainage pipe 4, and the running device 2 can move along the length direction of the track 6. The side of the track 6 is provided with a limited stopper. The running device 2 can move along the track 6, and the track 6 is provided with a limited stopper (not shown in the figure), so that the running device 2 will not be offset away from the track 6 during the movement, thereby preventing the ladder beam 1 from rotating around the axis of the drainage pipe 4.
