[0002] At present, the problem of waterproofing membrane leakage at the inner corners of multi-warehouse structures such as integrated pipe corridors often occurs during urban road construction. The traditional waterproofing membrane protection measures are: build a waterproofing protection brick wall before pouring the pipe corridor bottom plate, turn the outer waterproofing membrane up to the top of the waterproofing protection brick wall, and when supporting the outer template of the pipe corridor side wall, the steel pipe back ribs on the back of the template are generally directly pressed on the waterproofing membrane above the waterproofing protection brick wall, which is easy to damage the waterproofing membrane, thereby increasing the probability of water leakage in the structure. In addition to the above, when the outer waterproofing membrane is turned up to the top of the waterproofing protection brick wall, it needs to be folded 90°, and the folding part is prone to wrinkle damage, difficult to fit, and easy to deviate.

Therefore, the inner width of the L-shaped fixing frame 4 is equal to the width of the waterproofing protection brick wall 2, and the inner height of the L-shaped fixing frame 4 is equal to the height of the waterproofing protection brick wall 2. The L-shaped fixing frame 4 can just be stuck on the waterproofing protection brick wall 2. The inner width is the horizontal distance between the inner vertical plate 6 close to the side of the waterproofing protection brick wall 2 and the end of the lower horizontal plate 8 close to the pipe gallery 1. The inner height is the vertical distance between the bottom surface of the lower horizontal plate 8 and the bottom end of the inner vertical plate 6 or the outer vertical plate 5. In order to fix the entire L-shaped fixing frame 4, a number of corresponding drill holes 12 are provided on the upper wood 9 and the lower wood 10. The drill holes 12 are distributed along the length direction of the L-shaped fixing frame 4. The drill holes 12 pass through the L-shaped fixing frame 4. Steel chisels 13 are inserted into the corresponding drill holes 12 above and below the upper wood 9 and the lower wood 10. The steel chisels 13 are inserted into the ground to fix the L-shaped fixing frame 4 to prevent it from shifting.

[0016] An upper positive angle 15 is provided at the upper inner part of the waterproof protective brick wall 2 of the present invention, and a lower negative angle 16 is provided at the bottom inner part of the waterproof protective brick wall 2. The inner side mentioned here refers to the side close to the pipe gallery 1. A positive angle control strip 14 is fixed downwardly at one end of the bottom surface of the lower horizontal plate 8 close to the pipe gallery 1. The positive angle control strip 14 is made of PVC material, and the length of the positive angle control strip 14 is equal to the length of the L-shaped fixing frame 4. The curvature of the inner side surface of the positive angle control strip 14 matches the curvature of the upper positive angle 15 at the upper inner part of the waterproof protective brick wall 2.

It is preferred to provide an oil-proof sticker on the bottom surface of the lower horizontal plate 8 to further protect the waterproof membrane 3.

[0017] According to the above-mentioned internal corner waterproofing membrane protection device under the pipe gallery, a corresponding internal corner waterproofing membrane protection construction method under the pipe gallery includes the following steps: Step 1: Pour the bottom slab cushion of the tunnel 1 and use a trowel to control the flatness of the cushion.

[0018] Step 2: Build a waterproof protective brick wall 2, set an upper positive corner 15 on the upper inner side of the waterproof protective brick wall 2, and set a lower negative corner 16 on the inner bottom of the waterproof protective brick wall 2. Both the upper positive corner 15 and the lower negative corner 16 are treated with mortar. The upper and lower inner sides are rounded with mortar to obtain the upper positive corner 15 and the lower negative corner 16.

[0019] Step three: construct the waterproof membrane 3 at the bottom of the pipe gallery 1, and make the waterproof membrane 3 fit the waterproof protection brick wall 2 without hollows. Fold the waterproof membrane 3 to the top surface of the waterproof protection brick wall 2 at the upper positive corner 15, and make the waterproof membrane 3 fit the upper positive corner 15.

[0020] Step 4: Install the L-shaped fixing frame 4, let the external corner control strip 14 fit with the waterproof membrane 3 at the upper external corner 15, the external corner control strip 14 is pressed on the waterproof membrane 3 at the external corner, the lower horizontal plate 8 is pressed on the waterproof membrane 3 on the top surface of the waterproof protection brick wall 2, and the upper horizontal plate 7 and the lower horizontal plate 8 are tightly against the side wall of the bottom plate of the pipe gallery 1, and the inner vertical plate 6 is close to the outer side of the waterproof protection brick wall 2. Finally, insert the steel chisel 13 into the drill hole 12 to fix the L-shaped fixing frame 4, and protect the waterproof membrane 3 under the L-shaped fixing frame 4.

[0021] Step 5: Tie up the steel bars of the bottom plate and side wall of the pipe gallery 1, and support the outer side wall formwork of the pipe gallery 1. At this time, the steel pipe back ribs of the outer side wall formwork of the pipe gallery 1 are just above the supporting square wood 11, and the steel pipe back ribs of the outer side wall formwork of the pipe gallery 1 are pressed on the upper cross plate 7. The pressure of the steel pipe back ribs is shared by the upper cross plate 7, the supporting square wood 11, the lower cross plate 8 and the external angle control strip 14, so as to avoid the steel pipe back ribs directly pressing on the waterproofing membrane 3 and causing the waterproofing membrane 3 to be damaged. After the waterproofing membrane 3 is temporarily protected, the construction of the bottom plate and side wall of the pipe gallery 1 can be continued.

[0022] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them.
