Embodiment Construction

[0032] Next, the rigid sleeve valve tube assembly of the present invention and its usage method will be described in detail with reference to the accompanying drawings.

[0033] First, please refer to Figure 1A ~ Figure 1C , the rigid cuff tube assembly of the present invention includes a first-type cuff tube body 100 , a second-type cuff tube body 200 , and a third-type cuff tube body 300 . The first type sleeve valve body 100, the second type sleeve valve body 200, and the third type sleeve valve body 300 have the same pipe diameter size, and they are made of hot-rolled seamless steel tubes with a diameter of 42 mm and a wall thickness of 8 mm. Made of steel pipe.

[0034] Such as Figure 1A As shown, the length of the first type sleeve valve body 100 is 5 meters, the front end of the first type sleeve valve body 100 is closed, the length of the tip 110 is set to 10 cm, and the first type sleeve valve body 100 is far away from the tip One end of 110 is provided with inter...

Abstract

The invention discloses a rigid sleeve valve pipe assembly and a using method thereof. The rigid sleeve valve pipe assembly comprises a first type sleeve valve pipe body, a second type sleeve valve pipe body and a third type sleeve valve pipe body which are connected in sequence, wherein the first type sleeve valve pipe body, the second type sleeve valve pipe body and the third type sleeve valve pipe body have the same pipe diameter size, a plurality of groups of plum blossom type grout vent holes are separately formed in the first type sleeve valve pipe body and the second type sleeve valve pipe body along the pipe walls of the first type sleeve valve pipe body and the second type sleeve valve pipe body, longitudinal intervals of the every two adjacent groups of grout vent holes are set as 20-40cm, and each group of grout vent holes comprises four grout vent hole bodies with the cross sections in a cross shape formed surrounding the pipe walls. The rigid sleeve valve pipe assembly adapts depth and high-pressure grouting, the grout vent holes are formed in a sleeve valve pipe in a plum blossom mode, grout can be diffused in multiple directions, the stratum is effectively filled, anelastic connecting piece can ensure that under the condition of without slip casting, a rubber blanket can firmly cover the grout vent holes, and the rubber blanket is prevented from falling in the transportation process or in the mounting process.

Description

technical field [0001] The invention relates to the technical field of tunnel engineering, in particular to a construction component for reinforcing tunnel surrounding rock and a use method thereof. Background technique [0002] With the increasing scale of railway construction, there are more and more high-speed railway tunnels. During the tunnel construction process, the surrounding rock undergoes large deformation, the stability becomes poor, and landslide disasters occur frequently. When the tunnel construction reaches the fault fracture zone, due to the sudden drop in the grade of surrounding rock and the fact that the fault fracture zone is often rich in groundwater, the original initial support design is difficult to maintain the stability of the surrounding rock, and large-scale landslides occur. In addition, the shallow buried section of the tunnel has a thin covering layer and poor stability of the surrounding rock, and engineering accidents such as landslides are...
