Abstract
Description
Technical Field
[0001] The present application belongs to the technical field of water supply and drainage, and more specifically, to a construction structure for a drainage pipe without a pump-out or drainage connection. Background Art
[0002] In the process of drainage pipeline relocation, traditional construction methods such as earthbag cofferdam steel pipe diversion, pumping and drainage joint construction, and temporary pipeline blocking using airbags and brickwork are feasible in conventional construction environments. However, these traditional methods have gradually become limited in the face of complex and changing construction conditions. In particular, traditional methods are often difficult to adapt to complex working conditions such as limited working surface, deep pipeline burial, and large pipeline water flow.
[0003] First, when the construction work surface is limited, methods such as earthbag cofferdams and steel pipe diversions require a large space, which not only affects construction efficiency, but may also cause unnecessary interference to the surrounding environment. Secondly, for pipelines with greater burial depths, traditional plugging methods such as air bags and brickwork are difficult to deliver to the designated location, and it is difficult to ensure the plugging effect, which brings great inconvenience to the construction. Finally, when the water flow in the pipeline is large, traditional methods are difficult to effectively block the water flow, resulting in poor pumping and drainage effects, or even failure to complete the plugging. In addition, water-related operations also have safety hazards such as water scouring, release of toxic and harmful gases, and working in confined spaces, which pose a serious threat to construction personnel.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.
[0047] like Figure 1 , Figure 2 and Figure 4 As shown, the present application provides a drainage pipe non-pumping and drainage joint construction structure, including an existing drainage pipe 1, a diverted drainage pipe 2 and a joint structure 3.
[0048] The existing drainage pipe 1 refers to the existing drainage system, and the relocation section 11 is the part that needs to be relocated in this project. Due to the continuous updating of urban infrastructure, some old or non-conforming pipes need to be replaced or re-arranged.
[0049] The diverted drainage pipe 2 is a pipe laid according to the new drainage plan, and its function is to replace the relocation section 11 for drainage. When the diverted drainage pipe 2 is successfully connected to the existing drainage pipe 1, the drainage will no longer flow through the relocation section 11, thereby realizing the relocation of the drainage pipe.
[0050] The contact structure 3 is a structure located at the connection between the existing drainage pipe 1 and the diverted drainage pipe 2, and serves to connect the existing drainage pipe 1 and the diverted drainage pipe 2. The contact structure 3 is arranged at the end of the relocation section 11 and also at the end of the diverted drainage pipe 2. The contact structure 3 includes a contact well 31 constructed on the existing drainage pipe 1, and the contact well 31 is constructed by the reverse construction method, also known as a reverse well. This well construction method involves excavating and constructing the structure from top to bottom in sequence without erecting temporary supports, so that the structure itself acts as a retaining wall and support at the same time. In the construction of the working well, earth excavation and reinforced concrete construction are carried out in layers. The excavation depth of each layer needs to be controlled within the safe depth, and then the steel bar binding, formwork erection, concrete pouring and maintenance are carried out. After the concrete reaches a certain strength, the formwork is removed and the construction of the next layer section continues until the well bottom cushion and bottom plate required by the design are completed. The contact well 31 is provided with a diversion groove 32, a partition wall 33 and a plugging groove 34. One end of the guide groove 32 is arranged at the end of the relocation section 11, and the other end of the guide groove 32 is connected to the diverted drainage pipe 2; the guide groove 32 guides the water flow originally flowing to the relocation section 11 to the diverted drainage pipe 2, ensuring smooth drainage. The partition wall 33 is arranged on the outside of the guide groove 32 and on the side close to the relocation section 11, and the existing drainage pipe 1 runs through the partition wall 33; the outer wall of the guide groove 32, the partition wall 33 and the inner wall of the collision well 31 enclose to form a plugging groove 34; the partition wall 33 and the collision well 31 are key structures for realizing water flow diversion without pumping out water. When the existing drainage pipe 1 is broken, the water flows from one side of the partition wall 33, that is, the inner side of the guide groove 32, into the diverted drainage pipe 2; on the other side of the partition wall 33, that is, the inner side of the plugging groove 34, plugging materials 35 are filled to block the water flow from entering the relocation section 11, thereby realizing the diversion of the water flow to the diverted drainage pipe 2.
[0051] When constructing the drainage pipe without pumping and drainage collision construction structure of this application, there is no need for a large area of excavation site, which is suitable for the construction of pipelines with a large burial depth. Before breaking the existing drainage pipe 1, the masonry of the partition wall 33 can be carried out in a dry working environment, which greatly improves the construction efficiency. After breaking the existing drainage pipe 1, the remaining operations can be completed on the ground with the help of construction equipment, ensuring the safety of the operation and the safety of the personnel. In addition, during the construction process, the existing drainage pipe 1 can flow water normally, ensuring the normal operation of the drainage system.
[0052] To ensure the dryness of the indoor working environment of the collision well 31 and to prevent water from overflowing the plugging groove 34, Figure 3 ,and Figure 5As shown, in one embodiment of the present application, the top surface of the partition wall 33 needs to be higher than the top surface of the existing drainage pipe 1. After the existing drainage pipe 1 is broken, the water level overflowing from the existing drainage pipe 1 can never exceed the top surface of the partition wall 33. The top surface masonry height of the partition wall 33 is not fixed, but is flexibly adjusted according to the actual situation at the construction site. Specifically, its height needs to be calculated and adjusted based on key factors such as the pipe diameter, water flow size, and water pressure. The present application is also applicable to situations where the pipe is full of water or the downstream pipe has water pressure due to full water upstream. In this case, it is only necessary to further raise the height of the partition wall 33 to achieve a higher blocking water level. After breaking the existing drainage pipe 1, the water flow in the pipe will not overflow, and the dry working environment in the well chamber is always maintained, reducing the safety risks of construction workers.
[0053] In one embodiment of the present application, in order to ensure that the plugging groove 34 and the plugging material 35 can effectively stop the water flow and prevent leakage, the axial length L of the plugging groove 34 along the existing drainage pipe 1 needs to be greater than 0.5m, so as to ensure that the plugging groove 34 and the plugging material 35 have sufficient plugging thickness to ensure their ability to block the water flow. In other embodiments, the axial length L of the plugging groove 34 along the existing drainage pipe 1 can also be less than 0.5m. For example, if the plugging groove is technically feasible, the gate plate can be directly inserted into the plugging groove for plugging, so the size of the axial length L can be adjusted. The size of the axial length L depends on the actual plugging method used.
[0054] like Figure 6 As shown, in one embodiment of the present application, the existing drainage pipe 1 has a first breaking position and a second breaking position, and the first breaking position and the second breaking position are respectively arranged on both sides of the partition wall 33. Among them, the first breaking position is located on the side of the partition wall 33 facing the guide groove 32. At the first breaking position, it is only necessary to partially break the pipe wall of the existing drainage pipe 1 to create a suitable opening so that the water flow can smoothly flow into the guide groove 32 and then be guided to the diverted drainage pipe 2. The second breaking position is located on the side of the partition wall 33 facing the plugging groove 34. At the second breaking position, the existing drainage pipe 1 needs to be completely cut off. The purpose is to ensure that the existing drainage pipe 1 can be completely blocked from the broken position when the plugging material 35 is filled, so as to ensure that the plugging material 35 can be smoothly filled into the plugging groove 34, and the plugging effect of the plugging groove 34 and the plugging material 35 is ensured.
[0055] In one embodiment of the present application, the first end of the relocation section 11 is the water inlet end, and the second end of the relocation section 11 is the water outlet end. The first contact structure is provided at the water inlet end of the relocation section 11, and the second contact structure is provided at the water outlet end of the relocation section 11. The first contact structure and the second contact structure are relatively mirror-symmetrical in space, specifically, the guide groove of the first contact structure is connected to the existing drainage pipe 1 upstream, the guide groove of the second contact structure is connected to the existing drainage pipe 1 downstream, and the plugging groove of the first contact structure and the plugging groove of the second contact structure are clamped at both ends of the relocation section 11.
[0056] In one embodiment of the present application, the plugging material 35 includes a grille 351, a sandbag 352 and concrete 353. The grille 351 is inserted into the broken existing drainage pipe 1. The function of the grille 351 is to provide a support structure to ensure that the subsequent filled materials can be stably accumulated at the second broken position of the existing drainage pipe 1 and prevent the materials from being lost due to the impact of water flow. The sandbag 352 is filled into the plugging groove 34 and the broken existing drainage pipe 1. The sandbag 352 has good plasticity and density, and can effectively fill the gap and prevent water from passing through. In addition, the sandbag 352 can also withstand a certain water pressure to ensure the durability of the plugging effect. Finally, the concrete 353 is poured on the sandbag 352 in the plugging groove 34. The concrete 353 can not only further enhance the plugging effect, but also its hard and durable characteristics enable the plugging to withstand long-term water flow scouring and erosion.
[0057] The present application provides a method for constructing a drainage pipe without pumping and draining, comprising the following steps:
[0058] First, the diverted drainage pipe 2 is laid according to the preset drainage pipe relocation route to ensure that it can be smoothly connected with the existing drainage pipe 1.
[0059] Next, a collision well 31 is constructed at the end of the relocated section 11 of the existing drainage pipe 1. The construction of the collision well 31 must not only meet the engineering standards, but also consider its structural strength and stability to ensure the safety of subsequent construction. The construction method of the collision well 31 can specifically be caisson reverse construction or open excavation masonry, and the present application does not specifically limit the construction method of the collision well 31. Inside the collision well 31, a diversion groove 32 is further built. One end of the diversion groove 32 is set at the first breaking position of the existing drainage pipe 1, and the other end is connected to the diverted drainage pipe 2. In addition, a partition wall 33 is built between the first breaking position and the second breaking position of the existing drainage pipe 1 to separate the plugging groove 34. The plugging groove 34 is enclosed by the outer wall of the diversion groove 32, the partition wall 33 and the inner wall of the collision well 31, providing an operating space for subsequent plugging work.
[0060] Subsequently, a wire saw is used to perform pipe wall breaking operations at the first breaking position and the second breaking position of the existing drainage pipe 1. During the breaking process, the breaking size and position need to be strictly controlled to ensure that no unnecessary damage is caused to the drainage system.
[0061] Finally, the plugging material 35 is filled into the plugging groove 34 to block the incoming and outgoing water of the relocation section 11, ensuring that the water flow is completely diverted to the diverted drainage pipe 2. Then, the bumping well 31 is backfilled and compacted to complete the construction of the drainage pipe without pumping the bumping mouth.
[0062] In one embodiment of the present application, when filling the plugging material 35, in order to enhance the plugging effect and prevent material loss: a grid 351 is inserted at the first break position and the second break position respectively, and the grid 351 can play a role in blocking large particles in the pipeline, preventing the sandbags 352 and concrete 353 filled subsequently from being lost or shifted under the scouring of water flow. After inserting the two grids 351, the sandbags 352 are filled in the area between the two grids 351. As an intermediate filling layer, the sandbags 352 can not only effectively fill the gap, but also because of its compressibility, it can adapt to plugging grooves 34 of different shapes and sizes to ensure the tightness of the plugging. Finally, when the sandbags 352 are filled, concrete 353 is poured into the entire plugging groove 34. As the final solidification layer, the concrete 353 tightly combines the sandbags 352 and the grid 351 to form a solid and stable plugging structure. This structure can effectively block the incoming and outgoing water of the relocation section 11 for a long time, ensuring the safety and stability of the drainage system.
[0063] It should also be noted that when plugging, the grille 351 is against the pipe opening of the downstream diversion drainage pipe 2 in the plugging groove 34, and after the sandbag 352 is thrown in for simple plugging, the water flow in the plugging groove 34 becomes gentle, and at this time, concrete 353 is poured into the remaining space in the plugging groove 34 to form a better seal. If the entire plugging groove 34 is filled with sandbags 352 or other non-hydraulic materials, and finally the upper part of these filling materials is covered with concrete 353, although the plugging effect of this method is not good, the concrete mud 353 can be applied from the outside of the plugging groove 34 to the plugging end surface to ensure the plugging effect.
[0064] In one embodiment of the present application, when the partition wall 33 is built between the first breaking position and the second breaking position, the top surface of the partition wall 33 is higher than the top surface of the existing drainage pipe 1 to prevent water from overflowing.
[0065] In one embodiment of the present application, when constructing the guide groove 32 , in order to prevent water from overflowing the guide groove 32 , the construction height of the guide groove 32 needs to be greater than the height of the existing drainage pipe 1 and the diverted drainage pipe 2 .
[0066] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
