Embodiment 1
[0039] like Figure 1-8 , a tunnel lining structure filled with ceramsite, which includes a surrounding rock 1, primary support 3 is anchored on the tunnel rock mass of the surrounding rock 1 through bolts 2, and the inner layer of the primary support 3 is laid There is a waterproof layer 4, on the inner layer of the waterproof layer 4, a ceramsite filler 5 is laid, a steel arch 7 is set inside the ceramsite filler 5, and a secondary lining 8 is poured inside the steel arch 7. By adopting the above-mentioned tunnel lining structure, the initial support 3 is implemented in time after the tunnel is excavated, and the basic form is shotcrete and the anchor rod 2, and then the ceramsite filler 5 is set on the basis of the reserved deformation joints as the filling type. Lining, followed by the laying of the waterproof layer 4, the secondary lining 8 adopts the form of erecting steel arches and pouring integral molded concrete to give full play to the bearing capacity of the surrou...
Embodiment 2
[0050] Any construction method using ceramsite-filled tunnel lining structure is characterized in that it includes the following steps:
[0051] Step1: Before excavating the tunnel, grouting is applied to radially advanced small conduits. The small conduits are seamless steel pipes with a diameter of 30-50mm and a length of 25-40mm. Test confirmed, using high-pressure grouting pump grouting;
[0052] Step2: After the excavation of the tunnel, implement the initial support 3 in time, install the steel mesh, set the anchor rod 2, mix the concrete mixture mixed with the quick-setting agent and water into a slurry, and spray it on the wall of the tunnel to condense;
[0053] Step3: Install the automatic pressure gauge 6 to measure the deformation of the surrounding rock;
[0054] Step4: Lay the waterproof layer 4, adopt the membrane waterproof layer, and lay it on the entire section of the arch and the side wall. The material is geotextile and waterproof board, and set the system...
