Description
Technical Field
[0001] The utility model belongs to the technical field of pipe gallery, and in particular relates to an inner lining block used in a comprehensive urban pipe gallery. Background Art
[0002] At present, the construction of tunnel lining in China is mainly based on integral cast-in-place, which has problems such as high construction risk, high environmental pollution, long transportation distance in the well, and low construction efficiency. The use of prefabricated lining blocks can significantly shorten the construction period while ensuring quality, but prefabricated linings require sufficient assembly space, the size of the prepared components requires a certain degree of precision, there are many joints, and waterproofing is difficult. Some prefabricated lining blocks are in the shape of a whole square, which is not only large in size but also heavy, which is not conducive to installation and wastes materials; and when the installation vehicle hoists the prefabricated lining blocks, it usually uses slings to tie the prefabricated lining blocks and install them with the corridor wall. This has poor safety performance during the hoisting process and is also more troublesome to install. In particular, after the prefabricated lining blocks are installed with the corridor wall, it is very troublesome to untie the slings, which is time-consuming and laborious. Summary of the invention
[0003] The purpose of the utility model is to overcome the deficiencies of the prior art and to provide an inner lining block for an urban integrated pipe gallery. Under the premise of ensuring assembly requirements, the inner lining block is compact in size and light in weight, and the lifting is also more convenient and stable.
[0004] The purpose of the utility model is achieved through the following technical scheme. The lining block used in the urban integrated pipe gallery comprises a lining block body, the upper end of the lining block body is integrally cast with an upper lining block, and the upper lining block is a T-shaped structure; the lower end of the lining block body is integrally cast with a lower shelving block, and the lower shelving block is against the side of the transport channel cast at the bottom of the pipe gallery; the lining block body is arc-shaped, and the outer surface of the lining block body and the outer surface of the upper lining block are both arc-shaped, and coincide with the curvature of the side wall of the pipe gallery, the inner surface of the upper lining block is a vertical plane, the inner surface of the lining block body is an arc surface, and a connecting hanger for lifting the lining block is fixed between the inner surface of the upper lining block and the inner surface of the lining block body, and the top and bottom surfaces of the lower shelving block and the side surfaces against the side of the transport channel are all plane.
[0005] The beneficial effects of the present utility model are as follows: Compared with the prior art, through the integral casting and molding of the lining block body, the upper lining block and the lower resting block, and the upper lining block is of a T-shaped structure, adjacent lining blocks in the longitudinal direction of the pipe gallery can be in contact with each other through the upper lining block, so that a large gap will be left between the lining block bodies, which makes the volume of the entire lining block body small and the weight greatly reduced. At the same time, hoisting is more convenient; and a connecting lifting member for hoisting the lining block is fixed between the upper lining block and the lining block body, so that when hoisting the lining block, it is not necessary to use a sling to bind the precast lining block and install it with the pipe gallery wall, which makes hoisting and installation very convenient and has high safety performance.
[0006] Preferably, the connecting lifting member is fixed between the inner surface of the upper lining block and the inner surface of the lining block body by an embedding method, and is located at the center position between the upper lining block and the lining block body, and the connecting end surface of the connecting lifting member is flush with the inner surface of the lining block body; through the setting of the above structure, the setting of the connecting lifting member does not affect the outer surface of the overall structure of the lining block, and the orientation setting of the connecting lifting member makes the force stability more uniform when hoisting the lining block through the connecting lifting member.
[0007] Preferably, the connecting lifting member includes a lifting cylinder and embedding members. There are at least two embedding members, which are distributed at equal intervals in a surrounding manner along the outer circumferential wall of the lifting cylinder. The lifting cylinder and the embedding members are both embedded and cast together during the casting of the lining block body. An internal thread for rotatably connecting and fixing with a lifting member is provided in the lifting cylinder; through the setting of the above structure, the forming of the connecting lifting member is more convenient. At the same time, through the setting of the embedding members, the force of the lifting cylinder on the lining block is better, and an internal thread is provided in the lifting cylinder, which makes the connection with an external hoisting tool more convenient during the connection process.
[0008] Preferably, the bottom of the lifting cylinder is of a closed structure, and the upper end surface of the upper part is flush with the inner surface of the lining block body; the bottom is set to be a closed structure, so that when the lifting cylinder is buried in the lining block and integrally cast, it prevents the concrete slurry from entering the lifting cylinder. Through the upper end surfaces of the two being flush, the outer surface of the lining block is not affected.
[0009] Preferably, the embedding member is a steel bar, and the upper part of the embedding member is fixed to the outer circumferential wall of the lifting cylinder by welding. The lower part of the embedding member is bent and bent along the outer side direction of the lifting cylinder; through the setting of the above structure, the anti-pulling force of the embedding member in the lining block is better, so that the stability of the entire connecting lifting member is better during the lifting process after being connected to an external hoisting tool.
[0010] Preferably, a layer of nitrile cork rubber layer is coated on the outer surface of the lining block body and the outer surface of the upper lining block; in this way, when the inner lining block is installed and fitted with the side wall of the utility tunnel, it will not collide hard and cause the inner lining block to break. By setting the nitrile cork rubber layer, the fitting stability after installation is better. BRIEF DESCRIPTION OF THE DRAWINGS

A lower supporting block 3 is integrally cast at the lower end of the lining block body 1. The lower supporting block 3 abuts against the side of the transportation passage 5 cast at the bottom of the utility tunnel 4. The lining block body 1 is arc-shaped, and the outer surfaces of the lining block body 1 and the upper lining block 2 are both arc-shaped and coincide with the radian of the side wall of the utility tunnel 4. The inner surface of the upper lining block 2 is a vertical plane, the inner surface of the lining block body 1 is arc-shaped, and a connecting suspension member 6 for lifting the inner lining block is fixed between the inner surface of the upper lining block 2 and the inner surface of the lining block body 1. The top surface, bottom surface and the side surface of the lower supporting block 3 abutting against the side of the transportation passage 5 are all planar.
[0017] The connecting suspension member 6 is fixed between the inner surface of the upper lining block 2 and the inner surface of the lining block body 1 in an embedded manner, and is located at the exact center position between the upper lining block 2 and the lining block body 1. The connecting suspension member 6 is installed at this position, so that the weight of the upper lining block 2 is almost equal to the weights of the lining block body 1 and the lower supporting block 3. The stability during hoisting is better, the weight balance is better, and the inertial force is greatly reduced, which greatly reduces the risk of force damage to the overall inner lining block. Moreover, the connecting end face of the connecting suspension member 6 is flush with the inner surface of the lining block body 1.
[0018] The connecting suspension member 6 includes a suspension cylinder 61 and an embedded member 62. There are at least two embedded members 62, which are distributed equidistantly in a surrounding manner along the outer circumferential wall of the suspension cylinder 61. Both the suspension cylinder 61 and the embedded member 62 are embedded and cast integrally when the lining block body 1 is cast. An internal thread 63 for screwing and fixing with a lifting member is provided inside the suspension cylinder 61.
[0019] The bottom of the suspension cylinder 61 is a closed structure, and the upper end face of the upper part is flush with the inner surface of the lining block body 1.
[0020] The embedded member 62 is a steel bar, and the upper part of the embedded member 62 is fixed to the outer circumferential wall of the suspension cylinder 61 by welding. The lower part of the embedded member 62 is bent and bent along the outer side direction of the suspension cylinder 61.
[0021] A layer of nitrile cork rubber layer 7 is attached to the outer surfaces of both the lining block body 1 and the upper lining block 2.
[0022] The forming process of the present utility model is as follows: First, four embedded members 62 are arranged and fixed to the outer circumferential wall of the suspension cylinder 61 by welding at equal intervals, and the lower parts of the embedded members 62 protrude downward from the bottom of the suspension cylinder 61. Then, the connecting suspension member 6 is placed into the casting mold to integrally cast and form the inner lining block. Finally, the cured inner lining block is screwed and fixed with an external lifting tool through the internal thread 63 of the suspension cylinder 61, and is hoisted and installed on the side wall of the pipe gallery 4 by a multi-joint robot.
