Description

TECHNICAL FIELD

[0001] The application discloses an environment-friendly underground seamless waterproof guide wall structure and belongs to the technical field of basement outer wall waterproofing. BACKGROUND

[0002] Waterproof treatment of the root of an underground outer wall is the core of anti-permeation management of a construction project. Once the basement outer wall seeps, not only the property safety will be threatened, but also the structural quality will be damaged, and a safety hazard will be caused. In the prior art, a waterproof guide wall which is 300-500 mm higher than the raft is poured during construction of the underground structure bottom plate, so as to eliminate the structural weak gap between the outer wall and the raft and reduce the seepage risk. However, although this construction method is effective, the construction joint at the intersection of the outer wall and the waterproof guide wall often has problems of "rotten root" and "misalignment", which affects the engineering appearance and needs to be repaired later. In addition, in the traditional method, in the area with high underground water level, due to uneven quality control of the guide wall, the anti-permeation effect of the waterproof guide wall cannot be guaranteed, and once seepage occurs, the damaged area of the wall and indoor articles will be large, which will cause high maintenance cost and complex maintenance operation. Therefore, it is very important to optimize the waterproof structure and strengthen the construction quality control.

[0003] In order to solve the problems existing in the prior art, in the technical solutions disclosed in the Chinese utility model patents with the application numbers 202322949792.4 and 201320836615.9 and the application dates of November 1, 2023 and December 18, 2013 respectively and the patent names of "underground built-in concrete waterproof guide wall" and "guide wall structure of basement outer wall", a twice-pouring form is adopted, the waterproof guide wall and the raft are formed by first pouring, and then the outer wall is formed by second pouring. The outer wall is arranged outside the waterproof guide wall. The construction joint at the waterproof guide wall of the basement is changed from the original horizontal straight joint into a bent "L-shaped" joint, the waterproof channel in the traditional method is prolonged, and the waterproof performance of the whole waterproof guide wall is improved.

[0004] In order to further improve the anti-seepage performance, in the technical solutions disclosed in the above two utility model patents, a waterproof steel plate is further arranged at the upper portion of the waterproof guide wall, and the waterproof steel plate is poured into the waterproof guide wall when the waterproof guide wall is poured. Since the waterproof steel plate is arranged before the waterproof guide wall, and the waterproof steel plate is vertically arranged, it is found in actual construction that the fixation of the waterproof steel plate is a problem difficult to solve on site. Once the waterproof steel plate is not fixed firmly, the waterproof steel plate is easy to be displaced or tilted during pouring, so that the waterproof performance of the outer wall is affected.

DETAILED DESCRIPTION

[0023] Figures 1-5 It is the best embodiment of the utility model, and the following will be combined with the drawings to further explain the utility model. Figures 1-5 The utility model is further explained.

[0024] For example, Figure 1As shown, the environmentally friendly underground seamless water-stop guide wall structure includes a raft slab 8 and a water-stop guide wall 5. The water-stop guide wall 5 is perpendicular to the surface of the raft slab 8, and the water-stop guide wall 5 and the raft slab 8 are cast in one piece. Before casting, the raft slab reinforcement 7, the outer wall reinforcement 3, and the water-stop steel plate 2 are arranged, with the outer wall reinforcement 3 arranged on the outside of the guide wall formwork 6. After the casting is completed, the raft slab 8 and the water-stop guide wall 5 are formed simultaneously, and the raft slab reinforcement 7, the outer wall reinforcement 3, and the water-stop steel plate 2 are fixed.

[0025] After the water-stop guide wall 5 is poured and the guide wall formwork 6 is removed, the outer wall formwork 4 is placed outside the outer wall reinforcement 3, and then a second pour is carried out to form the outer wall 1 outside the water-stop guide wall 5. After the outer wall formwork 4 is removed, an environmentally friendly underground seamless water-stop guide wall structure is formed. Therefore, in this environmentally friendly underground seamless water-stop guide wall structure, the seepage path of groundwater is increased, the probability of leakage is reduced, and the appearance quality of the outer wall 1 is improved.

[0026] like Figures 2-4 As shown, it is formed by casting. Figure 1 The construction steps for the environmentally friendly seamless underground water-stop guide wall structure shown are as follows:

[0027] (1) Bind the raft slab reinforcement 7 and fix and bind the external wall reinforcement 3 at the water-stop guide wall 5.

[0028] (2) The formwork of the raft slab 8 is erected and reinforced. At the same time, the guide wall formwork 6 is set inside the bottom of the outer wall reinforcement 3 at the water-stop guide wall 5 position, and the outer wall reinforcement 3 and the bottom raft slab reinforcement 7 are used as the initial support.

[0029] (3) Fix the water-stop steel plate 2 by fixing clamp 9. Fixing clamp 9 is clamped on the upper end of the guide wall template 6 on both sides. Fixing clamp 9 is erected above the position of the water-stop guide wall 5. The water-stop steel plate 2 is placed at the lower part of the fixing clamp 9 so that the water-stop steel plate 2 is vertically clamped between the guide wall templates 6 on both sides.

[0030] like Figure 5 As shown, the fixing clamp 9 includes a horizontally arranged fixing angle steel 10, and multiple clamping mechanisms are arranged sequentially at the lower part of the fixing angle steel 10. The clamping mechanisms are arranged along the length direction of the guide wall template 6, and the waterstop steel plate 2 is clamped and fixed by the clamping mechanisms.

[0031] The clamping mechanism includes a fixed chamber 13 fixed at intervals below the horizontal plane of the fixed angle steel 10, an adjusting nut 12 corresponding to the fixed chamber 13 is provided at the upper part of the horizontal plane of the fixed angle steel 10, and an adjusting bolt 11 is provided that passes through the fixed angle steel 10 and the fixed chamber 13. The adjusting bolt 11 passes through the fixed angle steel 10 and the fixed chamber 13 and is threadedly connected to the adjusting nut 12.

[0032] A set of hinged arms 14 is hinged to each side of the fixed chamber 13. Each set of hinged arms 14 consists of two spaced-apart arms, and each hinged arm 14 is composed of two connecting rods rotatably connected by a hinge shaft. The hinge shafts of the two hinged arms 14 in each set are coaxial. The two hinged arms 14 in each set hang naturally, and a fixed foot 17 is provided at the lower end of each hinged arm 14.

[0033] A lifting block 18 is provided at the lower part of the fixed chamber 13. The adjusting bolt 11 extends to the lower part of the fixed chamber 13 and is rotatably connected to the lifting block 18. Since the adjusting bolt 11 is threadedly connected to the adjusting nut 12, the lifting block 18 can be raised and lowered by the adjustment bolt 11 when the adjusting bolt 11 is rotated.

[0034] A traction arm 19 is hinged to each end of the lifting block 18. The other end of the traction arm 19 extends to the hinge shaft of the hinge arm 14 on the same side and is rotatably connected to the hinge shaft on the corresponding side. Under the action of the traction arms 19 on both sides, it can be ensured that the lifting block 18 does not rotate with the adjusting bolt 11 when the adjusting bolt 11 is rotated to raise and lower the lifting block 18. When the lifting block 18 rises, the traction arms 19 on both sides pull the hinge arms 14 on both sides toward the center. When the fixed feet 17 at the bottom of the hinge arms 14 on both sides contact, the water-stop steel plate 2 placed between the fixed feet 17 on both sides is clamped.

[0035] At the lower part of the fixed angle steel 10, multiple positioning frames 15 are arranged at intervals along its length. Positioning slots 16 are installed on both sides of the bottom of each positioning frame 15, with the openings of the positioning slots 16 facing downwards and engaging with the upper edge of the corresponding guide wall template 6. Therefore, the fixed angle steel 10 is fixed to the upper part of the guide wall templates 6 on both sides by the positioning frames 15 and the positioning slots 16. Simultaneously, the clamping mechanism holds and fixes the water-stop steel plate 2 between the guide wall templates 6 on both sides. Before the clamping mechanism fixes the water-stop steel plate 2, the height of the water-stop steel plate 2 is adjusted to ensure that the lower half of the water-stop steel plate 2 enters the subsequently poured water-stop guide wall 5. Figures 2-3 As shown.

[0036] (4) The first pouring is carried out, and the raft 8 and the water-stop guide wall 5 are formed at the same time. After the pouring is completed and the demolding conditions are met, the fixing clamp 9 is contacted to clamp the water-stop steel plate 2, the fixing clamp 9 is removed, and the guide wall template 6 is removed.

[0037] (5) After roughening the top and sides of the water-stop guide wall 5, and after the upper external wall reinforcement 3 is tied, the formwork is closed. External wall formwork 4 is then placed on the outside of the external wall reinforcement 3, and the external wall formwork 4 is reinforced and corrected to ensure the wall is vertical. Figure 4 As shown.

[0038] (6) Pour the outer wall 1 and remove the outer wall formwork 4 after the formwork is ready for demolding.
