Description
Technical Field
[0001] The utility model belongs to the technical field of waterproof construction of underground pipe corridors, and in particular relates to a waterproof structure for a deformation joint connection part of an underground pipe corridor. Background Art
[0002] Integrated utility corridors, with their unique advantages, are becoming a trend in modern urban infrastructure construction. However, as underground structures with long spans and complex geological conditions, waterproofing them remains a significant challenge, and the treatment of expansion joints plays a crucial role in overall waterproofing. Currently, various methods exist for connecting and waterproofing expansion joints in integrated utility corridors in my country. However, as cities develop, the space and scale of integrated utility corridors increase, and the geological environment becomes more complex, more stable and reliable construction techniques are needed for connecting and waterproofing expansion joints.
[0003] In the existing technology, when it comes to waterproofing construction at expansion joints, it is necessary to use a centrally embedded steel-edge rubber waterstop. However, when it comes to the installation of the centrally embedded steel-edge rubber waterstop, since the centrally embedded steel-edge rubber waterstop is usually pre-fixed to the steel skeleton by wire tying or the like, this fixing method makes it difficult to accurately limit the steel-edge rubber waterstop to a predetermined position during the fixing stage. At the same time, during the concrete pouring process, since the degree of fixation of the steel-edge rubber waterstop is limited, the steel-edge rubber waterstop is very likely to be offset up and down or left and right due to the pouring of concrete, vibration or other external forces. This not only easily causes the steel-edge rubber waterstop to be damaged and reworked, but also makes it difficult to achieve the expected waterproofing effect. Utility Model Content
[0004] In order to solve the above problems, the utility model provides a waterproof structure for the connection part of the deformation joint of the underground pipeline corridor, and fixed steel bar sleeves fixedly connected and combined with the steel bar skeleton body are preset at both sides of the embedded rubber waterstop body. At the same time, the end faces of the fixed steel bar sleeves at both sides are combined with positioning assemblies. Then, the embedded rubber waterstop body can be stably constrained and fixed in a predetermined position by fixing the steel edges at both sides of the embedded rubber waterstop body with the positioning assemblies respectively. The fixing method of the embedded rubber waterstop body is reliable and easy to implement, as described below for details.
[0005] To achieve the above objectives, the present invention provides the following technical solutions:
[0006] The utility model provides a waterproof structure for the connection part of the deformation joint of the underground pipe gallery, which includes a buried rubber waterstop body and a steel frame body. The steel frame bodies are arranged at the outer positions of the two side corners of the buried rubber waterstop body, and the steel frame bodies at the two side positions are fixed with multiple vertically stacked fixed steel frame frames;
[0007] The steel edges on both sides of the embedded rubber waterstop body are located between the fixed steel bars on both sides, and the opposite end faces of the fixed steel bars on both sides are combined with positioning assemblies, and the steel edges are fixedly connected with the positioning assemblies on the corresponding sides, so as to stably constrain and fix the embedded rubber waterstop body in a predetermined position by limiting and fixing the steel edges with the positioning assemblies corresponding to the same side.
[0008] Preferably, the positioning assemblies include limiting clamps and matching slots, the opposite end faces of the fixed steel bar sleeves at both sides are vertically extended with limiting clamps, and the fixed steel bar sleeves at the same side are fixedly connected to the outer end faces of the limiting clamps, the opposite end faces of the limiting clamps at both sides are vertically opened with matching slots, and the matching slots are vertically through slots.
[0009] Preferably, the front and rear end faces of the steel edge are fixed with multiple positioning protrusions extending longitudinally, and the multiple positioning protrusions on the same side are located in the same vertical direction. The front and rear end faces of the limiting clamp are vertically provided with positioning guide grooves, and the positioning guide grooves are vertically connected with the corresponding matching clamping grooves. At the same time, the positioning protrusions are vertically slidably matched with the corresponding positioning guide grooves.
[0010] Preferably, the positioning guide grooves are all vertically arranged waist-shaped long grooves with open tops, the positioning protrusions are all circular flanges, and the outer bottom of the positioning protrusion at the lowest position is in contact with the inner bottom of the corresponding positioning guide groove.
[0011] Preferably, the horizontal cross-section of the matching slots is rectangular, and the outer end surfaces of the steel edges at both sides, which are away from each other, are in contact with the inner end surfaces of the corresponding matching slots.
[0012] Preferably, the limiting clamps are all upright U-shaped clamps, and the limiting clamps and all the corresponding fixed steel bar sleeves on the same side are fixedly connected by welding.
[0013] Preferably, the joining positions of the front and rear end faces of the steel edge and the outer end face of the limiting clamp are connecting welds, so that the joining positions of the front and rear end faces of the steel edge and the outer end face of the limiting clamp are fixed together by whole-seam welding.
[0014] The above-mentioned waterproof structure of the deformation joint connection part of the underground pipe gallery is adopted. Specifically, in the construction and use of the embedded rubber waterstop body, since the fixed steel bar sleeves fixedly connected and combined with the steel bar skeleton body are preset at both sides of the embedded rubber waterstop body, and the end faces of the fixed steel bar sleeves at both sides are combined with the positioning assembly, the embedded rubber waterstop body can be stably constrained and fixed in a predetermined position by the steel edges at both sides of the embedded rubber waterstop body being fixedly connected to the positioning assembly respectively. The fixing method of the embedded rubber waterstop body is reliable and easy to implement, which avoids the situation where the embedded rubber waterstop body is damaged and needs to be reworked during the concrete pouring process, and is conducive to ensuring the waterproof effect of the embedded rubber waterstop body. Specifically, the positioning assembly is vertically slidably matched with the matching slots at both sides by the steel edges of the embedded rubber waterstop body and vertically along the positioning guide groove by the positioning protrusion. The sliding guide method can make the embedded rubber waterstop body slide vertically to the predetermined position. The positioning and limiting method of the embedded rubber waterstop body is reliable and easy to implement, which is convenient for quickly limiting and guiding the embedded rubber waterstop body to the predetermined position, which is beneficial to improving the installation efficiency of the embedded rubber waterstop body. At the same time, after the embedded rubber waterstop body is guided and limited to the predetermined position, the positioning protrusion is clamped in the positioning guide groove to prevent the steel edge from being laterally displaced. Then, by applying the connecting weld at the joint position between the steel edge and the limiting clamp, the steel edge can be firmly and securely fixed. The whole seam welding method is used instead of the point local welding method to ensure the formation of a firm connecting seam on the steel edge and strengthen the fixation of the steel edge. It not only improves the deformation resistance and durability of the embedded rubber waterstop body, but also effectively avoids the displacement of the embedded rubber waterstop body during the concrete pouring construction process.
[0015] The beneficial effects are as follows: 1. The utility model is provided with fixed steel bar sleeves fixedly connected and assembled with the steel bar skeleton body at both sides of the embedded rubber waterstop body, and at the same time, the end faces of the fixed steel bar sleeves at both sides facing each other are combined with positioning assemblies, and then the embedded rubber waterstop body can be stably constrained and fixed in a predetermined position by respectively fixing the steel edges at both sides of the embedded rubber waterstop body with the positioning assemblies. The fixing method of the embedded rubber waterstop body is reliable and easy to implement, which avoids the situation where the embedded rubber waterstop body is damaged and needs to be reworked during the concrete pouring process, and is conducive to ensuring the waterproof effect of the embedded rubber waterstop body.
[0016] 2. The embedded rubber waterstop body can be vertically slid and moved to a predetermined position by means of the vertical sliding cooperation between the steel edge of the embedded rubber waterstop body and the matching slots at both sides and the vertical sliding guidance of the positioning protrusion along the positioning guide groove. The positioning restriction method for the embedded rubber waterstop body is reliable and easy to implement, which facilitates the rapid guidance of the embedded rubber waterstop body to the predetermined position, thereby improving the installation efficiency of the embedded rubber waterstop body.
[0017] 3. After the embedded rubber waterstop body is guided and limited to the predetermined position, the positioning protrusion is stuck in the positioning guide groove to prevent the steel edge from shifting laterally. Then, by applying connecting welds at the joint position of the steel edge and the limiting clamp, the steel edge can be firmly and securely fixed. The whole seam welding method is used instead of the point-to-point local welding method to ensure the formation of a firm connecting seam on the steel edge and strengthen the fixation of the steel edge. It not only improves the deformation resistance and durability of the embedded rubber waterstop body, but also effectively avoids the displacement of the embedded rubber waterstop body during the concrete pouring construction process.

[0025] To make the purpose, technical solution, and advantages of the present invention more clear, the technical solution of the present invention will be described in detail below. Obviously, the embodiments described are only some of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other implementation methods obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.
[0026] See also Figure 1-Figure 4 As shown, the utility model provides a waterproof structure for the connection part of the deformation joint of the underground pipe gallery, including a buried rubber waterstop body 1 and a steel frame body 3. The outer positions of the corners on both sides of the buried rubber waterstop body 1 are provided with steel frame bodies 3, and the steel frame bodies 3 on both sides are fixed with multiple vertically stacked fixed steel frames 2. The steel edges 101 on both sides of the buried rubber waterstop body 1 are located between the fixed steel frames 2 on both sides, and the end faces of the fixed steel frames 2 on both sides facing each other are combined with positioning assemblies 4, and the steel edges 101 are fixedly connected with the positioning assemblies 4 on the corresponding sides, so as to stably constrain and fix the buried rubber waterstop body 1 in a predetermined position by fixing the steel edges 101 with the corresponding positioning assemblies 4 on the same side. Specifically, the positioning assemblies 4 include limiting clamps 4. 02 and matching slots 401, the fixed steel bar sleeves 2 at both sides are vertically extended with limit card plates 402 at the opposite end faces, and the fixed steel bar sleeves 2 at the same side are fixedly connected to the outer end faces of the limit card plates 402, the limit card plates 402 at both sides are vertically opened with matching slots 401 at the opposite end faces, and the matching slots 401 are all through slots in the vertical direction, the front and rear end faces of the steel edge 101 are fixed with multiple positioning protrusions 404 along the longitudinal extension, and multiple positioning protrusions at the same side are fixed. 404 are all located in the same vertical direction, and the front and rear end surfaces of the limiting card plate 402 are vertically provided with positioning guide grooves 403, and the positioning guide grooves 403 are vertically connected to the corresponding matching card grooves 401, and the positioning protrusions 404 are vertically slidably matched with the corresponding positioning guide grooves 403. The purpose of this arrangement is to make the buried rubber water stop belt body 1 slide vertically through the steel edge 101 of the buried rubber water stop belt body 1 and the matching card grooves 401 at both sides and to guide the positioning protrusions 404 along the positioning guide grooves 403 vertically. The rubber waterstop body 1 slides vertically to a predetermined position, and the positioning and limiting method of the embedded rubber waterstop body 1 is reliable and easy to implement. More specifically, the steel edge 101 of the embedded rubber waterstop body 1 slides vertically with the matching slots 401 on both sides and the positioning protrusion 404 slides vertically along the positioning guide groove 403 to enable the embedded rubber waterstop body 1 to slide vertically to a predetermined position. The positioning and limiting method of the embedded rubber waterstop body 1 is reliable and easy to implement.
[0027] See also Figure 1-Figure 2 As shown, the positioning assembly 4 is optimized as follows. Specifically, the positioning guide grooves 403 are all vertically arranged waist-shaped long grooves with open tops, the positioning protrusions 404 are all circular flanges, and the outer bottom of the positioning protrusion 404 at the lowest position is in contact with the inner bottom of the corresponding positioning guide groove 403. If it is arranged in this way, first, after the embedded rubber waterstop body 1 is guided and limited to the predetermined position, the positioning protrusion 404 is stuck in the positioning guide groove 403 to prevent the steel edge 101 from lateral displacement. At the same time, the positioning flange at the lowest position is in contact with the lowest position of the positioning groove, which can also clearly indicate that the embedded rubber waterstop body 1 is lowered into place. Optionally, the horizontal cross-section of the mating slots 401 is rectangular, and the outer end faces of the steel edges 101 at both sides that are away from each other are in contact with the inner end faces of the corresponding mating slots 401, so that the steel edges 101 have a good positioning and guiding design when sliding vertically along the mating slots 401, and it also facilitates the mating slots 401 at both sides to limit and constrain the steel edges 101 laterally.
[0028] See also Figure 1-Figure 4 As shown, further, the limiting clips 402 are all upright U-shaped clips, and the limiting clips 402 are fixedly connected to all the corresponding fixed steel bar sleeves 2 on the same side by welding, so that the design style of the limiting clips 402 meets the use requirements and is easy to process and manufacture, and at the same time, the limiting clips 402 can be firmly fixed to all the fixed steel bar sleeves 2. Furthermore, the front and rear end faces of the steel edge 101 and the outer end face of the limiting clip 402 are connected at the joint position of the connecting weld 405, so that the front and rear end faces of the steel edge 101 and the outer end face of the limiting clip 402 are fixedly connected together by the whole seam welding method. Since the whole seam welding method is used instead of the point local welding method, it is ensured that a strong connection seam is formed on the steel edge 101, thereby strengthening the fixation of the steel edge 101.
[0029] The above structure is adopted, specifically in the construction and use of the embedded rubber waterstop body 1, since fixed steel bar sleeves 2 fixedly connected and combined with the steel bar skeleton body 3 are preset at both sides of the embedded rubber waterstop body 1, and the end faces of the fixed steel bar sleeves 2 at both sides are combined with positioning assemblies 4, then the embedded rubber waterstop body 1 can be stably constrained and fixed in a predetermined position by the steel edge portions 101 at both sides of the embedded rubber waterstop body 1 respectively fixedly connected with the positioning assemblies 4. The fixing method of the embedded rubber waterstop body 1 is reliable and easy to implement, avoiding the situation where the embedded rubber waterstop body 1 is damaged and reworked during the concrete pouring process, which is conducive to ensuring the waterproof effect of the embedded rubber waterstop body 1. Specifically, with respect to the positioning assembly 4, the embedded rubber waterstop body 1 can be made waterproof by vertically sliding the steel edge portions 101 of the embedded rubber waterstop body 1 with the matching slots 401 at both sides and vertically sliding along the positioning guide grooves 403 through the positioning protrusions 404. The embedded rubber waterstop body 1 slides vertically to the predetermined position, and the positioning and limiting method of the embedded rubber waterstop body 1 is reliable and easy to implement, which is convenient for quickly limiting and guiding the embedded rubber waterstop body 1 to the predetermined position, and is beneficial to improving the installation efficiency of the embedded rubber waterstop body 1. At the same time, after the embedded rubber waterstop body 1 is guided and limited to the predetermined position, the positioning protrusion 404 is stuck in the positioning guide groove 403 to prevent the steel edge 101 from being horizontally shifted, and then by The method of applying connecting welds 405 at the joints between the steel edge 101 and the limiting clamp 402 can ensure that the steel edge 101 is firmly and securely fixed. The whole seam welding method is used instead of the local welding method, which ensures the formation of a firm connecting seam on the steel edge 101 and strengthens the fixation of the steel edge 101. It not only improves the deformation resistance and durability of the embedded rubber waterstop body 1, but also effectively avoids the displacement of the embedded rubber waterstop body 1 during the concrete pouring construction process.
