Technical Field

[0001] This utility model relates to the field of prestressed duct grouting technology, and specifically discloses a prestressed duct grouting structure for small space conditions. Background Technology

[0002] In existing prestressed duct grouting construction, the duct space is relatively spacious, and anchor plates are usually set at the ends for grouting. However, in actual working conditions, the space of the components is narrow, making it impossible to use anchor plates to complete the prestressed duct grouting. This is especially true when constructing scaled-down test components of the formwork cap beam, where the prestressed ducts of the components are densely packed, and it is inconvenient to set grouting holes at the beam ends. Utility Model Content

[0003] The purpose of this invention is to provide a prestressed duct grouting structure for small-space applications, which solves the technical problem of completing prestressed duct grouting when anchor plates cannot be used in small-space applications.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A prestressed duct grouting structure for small-space applications includes a grouting component and a reinforcing cage surrounding the grouting component. The grouting component comprises multiple horizontally arranged corrugated pipes and a grouting component on each corrugated pipe. The corrugated pipes are arranged in a multi-layer structure with uniform spacing between each layer and vertical staggered between adjacent layers. The grouting component is located on the belly of the corrugated pipe and includes a tee joint on the corrugated pipe, a grouting pipe on the tee joint, and a sealing ring between the tee joint and the corrugated pipe. The sealing component includes a T-shaped tee connector with a horizontal and a vertical section. The tee connector has T-shaped through holes along the horizontal and vertical sections. Both ends of the horizontal section of the tee connector are fitted onto and connected to the corrugated pipe. One end of the grouting pipe is connected to the vertical end of the tee connector. The sealing component includes two sealing sleeves respectively located between the two ends of the horizontal section of the tee connector and the corrugated pipe. Each sealing sleeve includes a first sleeve, a reducing sleeve, and a second sleeve connected in sequence. The first sleeve and the second sleeve are respectively fitted onto the horizontal ends of the corrugated pipe and the tee connector.

[0006] Furthermore, the joint between the horizontal part of the tee connector and the corrugated pipe is provided with a sealing material, which is a soft rubber strip.

[0007] Furthermore, the inner diameter of the first socket is smaller than the inner diameter of the second socket, and the first socket and the second socket have the same length.

[0008] Furthermore, the vertical end of the tee fitting is fitted onto the grouting pipe.

[0009] Furthermore, the sealing sleeve is a one-piece molded rubber product.

[0010] Furthermore, the steel cage includes multiple layers of transverse and longitudinal steel bars, which are distributed in a grid pattern around the corrugated pipe.

[0011] Furthermore, the top of the grouting pipe is equipped with a sealing plug.

[0012] Compared with the prior art, this utility model has the following features and beneficial effects:

[0013] This utility model incorporates a grouting component within a small-space working component. The grouting component includes multiple horizontally arranged corrugated pipes and a grouting part on each corrugated pipe.

[0018] The embodiments described herein are specific implementations of this utility model, used to illustrate the concept of this utility model. They are all illustrative and exemplary, and should not be construed as limiting the implementation methods or scope of this utility model.

These technical solutions include those that make any obvious substitutions and modifications to the embodiments described herein.

[0019] This utility model discloses a prestressed duct grouting structure for use in small-space applications, such as... Figure 1 and Figure 2 As shown, the device includes a grouting component located within a small-space working condition component, and a reinforcing cage located around the grouting component. The grouting component includes multiple horizontally arranged corrugated pipes 1, and a grouting component 2 installed on each corrugated pipe 1. The corrugated pipes 1 are arranged in multiple layers, with uniform spacing between each layer and vertically staggered between different layers. The grouting component 2 is located on the belly of the corrugated pipe 1, and the grouting components 2 on adjacent layers of corrugated pipe 1 are respectively located near different ends of the corrugated pipe 1. The grouting component 2 includes a tee joint 201 installed on the corrugated pipe 1. The grouting pipe 202 is mounted on the tee joint 201, and the sealing component 203 is located between the tee joint 201 and the bellows 1. The tee joint 201 has a T-shaped structure, including a horizontal part and a vertical part. The interior of the tee joint 201 has T-shaped through holes along the horizontal and vertical parts, which are connected through each other. Both ends of the horizontal part of the tee joint 201 are fitted onto the bellows 1 and are connected through the bellows 1. The joint between the horizontal part of the tee joint 201 and the bellows 1 is provided with sealing material, which is a soft rubber strip, to increase the sealing between the tee joint 201 and the bellows 1. The sealing of the connection ensures that the vertical part of the tee connector 201 is connected to the bellows 1. The inner diameter of the horizontal part of the tee connector 201 decreases by 1mm near the port. The grouting pipe 202 is a hollow tubular structure. One end of the grouting pipe 202 is connected to the vertical end of the tee connector 201. The vertical end of the tee connector 201 is fitted onto the grouting pipe 202, thus connecting the grouting pipe 202 to the bellows 1. A sealing plug is provided at the top of the grouting pipe 202. The sealing component 203 includes two sealing sleeves respectively located between the two ends of the horizontal part of the tee connector 201 and the bellows 1. The sealing sleeve is made of rubber and is integrally molded. The sealing sleeve includes a sleeve part one, a reducing part and a sleeve part two connected in sequence. In its natural state, the inner diameter of the sleeve part one is smaller than the inner diameter of the sleeve part two. The sleeve part one and the sleeve part two have the same length. The sleeve part one and the sleeve part two are respectively fitted onto the horizontal ends of the corrugated pipe 1 and the tee joint 201, further increasing the sealing between the two ends of the horizontal part of the tee joint 201 and the corrugated pipe 1. The reinforcing cage includes multiple layers of transverse reinforcing bars 3 and longitudinal reinforcing bars 4. The transverse reinforcing bars 3 and the longitudinal reinforcing bars 4 are distributed in a grid pattern around the corrugated pipe 1.

[0020] This utility model achieves prestressed duct grouting in small-space working conditions by setting a grouting component in the working condition. The grouting component includes multiple horizontally arranged corrugated pipes and a grouting component on each corrugated pipe. The grouting component includes a tee joint on the corrugated pipe and a grouting pipe on the tee joint, which leads the grouting hole to the upper surface of the component and completes the grouting from the top of the component. This realizes prestressed duct grouting when the working condition space of the component is small and anchor plates cannot be used. The sealing component between the two ends of the horizontal part of the tee joint and the corrugated pipe is used to further increase the sealing performance between the two ends of the tee joint and the corrugated pipe.
