[0023] The present utility model provides a precast prestressed concrete underground pipe gallery, which includes a pipe gallery body 101 and a connecting mechanism. The connecting mechanism includes a frame body 104, two groups of splicing components, multiple groups of reinforcing components and a hoisting component. Each group of the splicing components includes an installation box 105, two groups of abutting members and a plugging member. Each group of the abutting members includes a sliding rod 106, a spring 107, an abutting block 108 and a disc 109. The plugging member includes a vertical plate 110, a connecting plate 111 and a tapered plate 112. Each group of the reinforcing components includes a T-shaped plate 113, a bottom plate 114 and multiple pins 115. The hoisting component includes a hanging rod 116 and two groups of fixing members. Each group of the fixing members includes a mounting plate 117 and a bolt 118. The foregoing solution solves the problems in the prior art that it is not convenient to splice the pipe gallery and water leakage easily occurs at the joints.

[0024] For this specific embodiment, the frame body 104 is fixedly connected to the pipe gallery body 101 and is located at one end of the pipe gallery body 101. The end of the pipe gallery body 101 away from the frame body 104 has a groove 102. Two sets of the splicing components are symmetrically arranged on both sides of the pipe gallery body 101. The installation box 105 is fixedly connected to the pipe gallery body 101 and is located on one side of the pipe gallery body 101. Two sets of the abutting members are symmetrically arranged at both ends of the installation box 105. The sliding rod 106 penetrates through the installation box 105 and is slidably connected to the installation box 105. One end of the sliding rod 106 is fixedly connected to the disc 109, and the other end of the sliding rod 106 is fixedly connected to the abutting block 108. The spring 107 is sleeved outside the sliding rod 106. One end of the spring 107 is fixedly connected to the abutting block 108, and the other end of the spring 107 is fixedly connected to the installation box 105. The plug-in member is arranged outside the pipe gallery body 101. Multiple sets of the reinforcement components are all arranged on the lower surface of the pipe gallery body 101. The hoisting component is arranged on the upper surface of the pipe gallery body 101. When specifically in use, insert the frame body 104 on the pipe gallery body 101 into the groove 102 on another pipe gallery body 101, so as to connect the two pipe gallery bodies 101 end to end, thereby effectively preventing water seepage between the two pipe gallery bodies 101. At the same time, insert the plug-in member on the pipe gallery body 101 into the installation box 105 on another pipe gallery body 101. Under the action of the spring 107, the abutting block 108 abuts the plug-in member, so that the plug-in member is fixed to the installation box 105, thereby fixing the two pipe gallery bodies 101.

[0025] Wherein, the vertical plate 110 is fixedly connected to the pipe gallery body 101. One end of the connecting plate 111 is fixedly connected to the vertical plate 110, and the other end of the connecting plate 111 is fixedly connected to the conical plate 112. When specifically in use, when connecting the two pipe gallery bodies 101 end to end, the vertical plate 110 will be attached to the installation box 105. The vertical plate 110 drives the conical plate 112 to insert into the installation box 105 through the connecting plate 111. During the process of the conical plate 112 inserting into the installation box 105, it will abut the abutting block 108 to move. The abutting block 108 drives the disc 109 to move through the sliding rod 106, and the spring 107 contracts. When the vertical plate 110 is attached to the installation box 105, the spring 107 rebounds, so that the abutting block 108 abuts the conical plate 112 in the installation box 105, thereby splicing and fixing the two pipe gallery bodies 101.

[0026] Secondly, the utility tunnel body 101 has a T-shaped groove 103. The T-shaped plate 113 is arranged in the T-shaped groove 103. The bottom plate 114 is fixedly connected to the T-shaped plate 113 and fits with the lower surface of the utility tunnel body 101. A plurality of the pins 115 are fixedly connected to the lower surface of the bottom plate 114. During specific use, the T-shaped plate 113 is inserted into the T-shaped groove 103, thereby fixing the bottom plate 114 to the utility tunnel body 101. By inserting the plurality of pins 115 into the soil, the stability of the utility tunnel body 101 is enhanced.

[0027] Meanwhile, two sets of the fixing members are arranged on the upper surface of the utility tunnel body 101. Two ends of the hanging rod 116 are respectively fixedly connected to the two sets of the fixing members. During specific use, the hanging rod 116 is fixed to the utility tunnel body 101 by the two sets of the fixing members. The hanging rod 116 facilitates the use of a crane to hoist the utility tunnel body 101.

[0028] In addition, the mounting plate 117 fits with the upper surface of the utility tunnel body 101. The bolt 118 penetrates through the mounting plate 117 and is threadedly connected to the utility tunnel body 101. During specific use, the mounting plate 117 is fixed to the utility tunnel body 101 by using the bolt 118.

[0029] When using a precast prestressed concrete underground utility tunnel of this embodiment, during specific use, the frame 104 on the utility tunnel body 101 is inserted into the groove 102 on another utility tunnel body 101, thereby connecting the two utility tunnel bodies 101 end to end, effectively preventing water seepage between the two utility tunnel bodies 101. Meanwhile, during the process of connecting the two utility tunnel bodies 101 end to end, the vertical plate 110 drives the tapered plate 112 to insert into the installation box 105 through the connecting plate 111. During the process of the tapered plate 112 inserting into the installation box 105, it will abut against the abutting block 108 to move. The abutting block 108 drives the disc 109 to move through the sliding rod 106 and makes the spring 107 contract. When the vertical plate 110 fits with the installation box 105, the spring 107 rebounds, so that the abutting block 108 abuts the tapered plate 112 in the installation box 105, thereby splicing and fixing the two utility tunnel bodies 101. This method can effectively solve the problems in the prior art that it is not convenient to splice the utility tunnels and the joints are prone to water seepage.

[0030] The second embodiment of this application is:

[0031] On the basis of the first embodiment, please refer to Figure 5 , Figure 5It is a schematic structural diagram of the second embodiment of the present utility model.

[0032] The present utility model provides a precast prestressed concrete underground pipe gallery, which further includes a filter plate 201, two clamping plates 202 and multiple partition plates 203.

[0033] For this specific embodiment, the filter plate 201 is arranged inside the pipe gallery body 101. One ends of the two clamping plates 202 are respectively fixedly connected to the filter plate 201, and the other ends of the two clamping plates 202 respectively penetrate through the pipe gallery body 101. The multiple partition plates 203 are all arranged on the upper surface of the filter plate 201. When in specific use, the filter plate 201 is installed inside the pipe gallery body 101 through the two clamping plates 202, and the filter plate 201 is divided by the multiple partition plates 203, so as to facilitate the placement of pipelines for different projects.

[0034] When using a precast prestressed concrete underground pipe gallery of this embodiment, when in specific use, pipelines for different projects are placed on the filter plate 201 and separated by the multiple partition plates 203. The filter plate 201 enables the pipelines to be away from the bottom surface of the pipe gallery body 101, thereby reducing the moisture received by the pipelines and prolonging the service life of the pipelines.
