[0021] This utility model provides an inner mold for an airbag in a tunnel center drainage ditch, including a rubber sleeve 101, a structural sleeve 102, and a detachable sealing pressure measuring tube. The detachable sealing pressure measuring tube includes an air inlet pipe 103, a detection pipe 105, a disassembly pipe 109, an installation pipe 110, a sealing pipe 111, a protective ring 104, a pressure pipe 106, a pressure gauge 107, a pointer 108, a return cavity 112, a connecting groove 116, a fixing ring 113, a return ring 114, a vent hole 115, a connecting thread 117, and a disassembly thread 118. This solution solves the problem that current airbag inner molds cannot be unilaterally replaced, and damage to the sealing components leads to overall damage and significant economic losses. It is understood that the aforementioned solution allows for the replacement of the airbag inner mold during tunnel drainage pipe construction. The rubber sleeve 101 is placed in the designated position, and then the inflation device is connected to the connecting groove 116 of the sealing tube 111. The rubber sleeve 101 is then inflated, and the staff observes the pointer 108 in the pressure gauge 107 in real time. When the pointer 108 reaches the target value, the pre-set construction of the tunnel drainage channel is completed. When the components in the sealing tube 111 lose their sealing effect, the installation tube 110 and the sealing tube 111 can be disassembled and replaced through the disassembly tube 109. This effectively solves the problem that the current airbag inner mold cannot be replaced unilaterally, and the damage to the sealing components will lead to the overall damage and cause great economic losses, while retaining the original beneficial effects.

[0022] In this specific embodiment, the structural sleeve 102 is fixedly connected to the rubber sleeve 101 and located inside the rubber sleeve 101; the air inlet pipe 103 is fixedly connected to the rubber sleeve 101 and located above the rubber sleeve 101; the detection pipe 105 is fixedly connected to the air inlet pipe 103 and located above the air inlet pipe 103 away from the rubber sleeve 101; the disassembly pipe 109 is fixedly connected to the detection pipe 105 and located at one end of the detection pipe 105 away from the air inlet pipe 103; the disassembly thread 118 is fixedly connected to the disassembly pipe 109 and located inside the disassembly pipe 109; the mounting pipe 110 is detachably connected to the disassembly pipe 109 and located on the inner side of the disassembly pipe 109 away from the detection pipe 105; and the connecting thread 117 is fixedly connected to the mounting pipe 110. The connecting thread 117 is rotatably connected to the disassembly thread 118 and located inside the disassembly tube 109. The sealing tube 111 is fixedly connected to the mounting tube 110 and located at the end of the mounting tube 110 away from the disassembly tube 109. The main component of the structural sleeve 102 is made of high-strength fiber cloth, which effectively strengthens the overall structural strength in formal use while ensuring the extensibility of the rubber sleeve 101. When the components in the sealing tube 111 lose their sealing effect, the mounting tube 110 and the sealing tube 111 can be disassembled and replaced through the disassembly tube 109. The disassembly thread 118 and the connecting thread 117 cooperate with each other to facilitate the disassembly and connection of the disassembly tube 109 and the mounting tube 110.

[0023] The protective ring 104 is detachably connected to the rubber sleeve 101 and is located above the rubber sleeve 101. The protective ring 104 is disposed on the outer surface of the air intake pipe 103. The pressure pipe 106 is fixedly connected to the detection pipe 105 and is located inside the detection pipe 105. The pressure pipe 106 is perpendicular to the detachable pipe 109. The pressure gauge 107 is detachably connected to the pressure pipe 106 and is located on the side of the pressure pipe 106 away from the detection pipe 105. The pointer 108 is rotatably connected to the pressure gauge 107 and is located inside the pressure gauge 107. The protective ring 104 is an auxiliary functional component that protects the air intake pipe 103, while the pressure pipe 106 is an auxiliary functional component that works with the pressure gauge 107 and the pointer 108 to detect the current air pressure.

[0024] Secondly, the reflux chamber 112 is fixedly connected to the sealing tube 111 and is located inside the sealing tube 111. The connecting groove 116 is fixedly connected to the sealing tube 111 and is located inside the sealing tube 111. The connecting groove 116 is located on the inner side of the sealing tube 111 away from the reflux chamber 112 and on the inner side of the sealing tube 111 away from the disassembly tube 109. The reflux chamber 112 is the place for sealing to prevent backflow.

[0025] Meanwhile, the fixing ring 113 is fixedly connected to the sealing tube 111 and located inside the sealing tube 111. The fixing ring 113 is also located inside the reflux cavity 112. The reflux ring 114 is slidably connected to the sealing tube 111 and located inside the sealing tube 111. The reflux ring 114 is located on the inner side of the reflux cavity 112 away from the fixing ring 113. The vent hole 115 is fixedly connected to the reflux ring 114 and located inside the reflux ring 114. The fixing ring 113 and the reflux ring 114 effectively form a simple anti-backflow structure, thereby achieving a sealing effect.

[0026] When using this invention for tunnel drainage pipeline construction, the rubber sleeve 101 is placed in the designated position, and then the inflation device is connected to the connecting groove 116 of the sealing pipe 111. Inflation of the rubber sleeve 101 is then started, and the staff observes the pointer 108 in the pressure gauge 107 in real time. When the pointer 108 reaches the target value, the pre-set construction of the tunnel drainage channel is completed. When the components in the sealing pipe 111 lose their sealing effect, the installation pipe 110 and the sealing pipe 111 can be disassembled and replaced through the disassembly pipe 109. This effectively solves the problem that the current airbag inner mold cannot be replaced unilaterally, and the damage to the sealing components will lead to the overall damage and cause great economic losses, while retaining the original beneficial effects.
