Description

Technical Field

[0001] This invention belongs to the field of building construction technology, and in particular relates to a construction method and interface structure for the interface between a construction trench and the side wall of a water tank. Background Technology

[0002] The statements in this section are merely background information related to the present invention and do not necessarily constitute prior art.

[0003] Power plants have numerous channels (such as pipe trenches and water ditches) that frequently intersect with the walls of various water tanks. Wastewater is often discharged into these tanks for purification, especially water that is corrosive to concrete and steel reinforcement. This can easily create seepage channels between the outer wall of the channel and the side wall of the water tank, affecting the durability of the tank's sidewalls. Waterproofing at these interfaces is complex and difficult to implement.

[0004] To address the problem of seepage channels easily forming between the outer wall of the ditch and the side wall of the pool, according to Figure 1 and Figure 2 The existing construction process is as follows: a horizontal interface that can be horizontally connected to the ditch is reserved on the side wall 2 of the pool, and waterproofing is done around the reserved interface. The waterproof joint 3 needs to be separately equipped with a horizontally connected steel bar with a sealing element wrapped with a rubber waterstop. A sealing element 4 (such as a rubber waterstop) is installed on the bottom plate and side wall at the reserved interface. Soil 5 is backfilled around the outside of the pool and compacted. Then, reinforced concrete is poured for the bottom plate and side wall of the ditch.

[0005] However, the above construction techniques have the following problems:

[0006] (1) The waterproof joint plate at the pool wall is relatively thin, and the steel bars need to be anchored into the side wall of the pool, resulting in concentrated steel bars in the pool wall and difficulty in concrete pouring; (2) The waterproof joints at the ditch and the waterproof joints at the pool wall protrude from the side wall, making it difficult to support the formwork in this part and resulting in low construction efficiency; (3) The waterproof joints at the outside of the pool side wall protrude from the pool wall, and the backfill soil under the bottom plate cannot be compacted, resulting in insufficient bearing capacity of the backfill soil here; (4) The waterproof joints at the ditch and the pool wall are poured in batches, which easily leads to water leakage; (5) The labor cost is high, the process is complicated, the performance is poor, and the construction is difficult. Summary of the Invention

[0007] In order to solve the technical problems existing in the background art, the present invention provides a construction method and interface structure for the interface between the construction trench and the side wall of the pool. By constructing the interface separately and independently, the tightness and integrity of the interface with the side wall of the pool can be guaranteed.

[0008] To achieve the above objectives, the present invention adopts the following technical solution:

[0009] The first aspect of the present invention provides a construction method for the interface between a construction trench and the side wall of a water tank.

[0010] A construction method for the interface between a construction trench and a water tank sidewall, comprising:

[0011] During the construction of the water tank, a channel opening of the required dimensions is pre-reserved on the side wall of the tank. A first sealing element is installed on the side wall to which the opening belongs, and a reinforcing bar is pre-reserved on the inside of the side wall to which the opening belongs.

[0012] During the later stages of ditch construction, when the ditch reaches the side wall of the pool, the bottom slab and side wall of the ditch are directly constructed inside the opening in the side wall of the pool.

[0013] A second sealing element is inlaid around the perimeter of the pool sidewall where it contacts the channel;

[0014] Use the pre-reserved reinforcing bars on the inner side wall of the opening to tightly connect the channel and the pool wall;

[0015] The channel is extended into the side wall of the pool and an inclined drip line is made to prevent water in the channel from flowing directly into the pool and flowing through the gap between the channel and the pool wall.

[0016] A waterproof layer is installed at the interface between the ditch and the side wall of the pool to prevent water from seeping into the gap between the pool wall and the ditch when water flows back into the pool.

[0017] A second aspect of the present invention provides an interface structure between a construction trench and the side wall of a water tank.

[0018] An interface structure between a construction trench and a water tank sidewall, comprising:

[0019] First seal, reinforcing rib, second seal, drip line and waterproof layer;

[0020] The first sealing element is installed on the side wall of the pool to which the opening belongs; the opening is pre-reserved on the side wall of the pool;

[0021] The tendon is pre-reserved on the inner side wall of the pool to which the opening belongs;

[0022] The second sealing element is embedded around the perimeter of the pool sidewall that contacts the channel; wherein the channel bottom plate and the pool sidewall are inside the opening in the pool sidewall;

[0023] The drip line is inclined and is set inside the side wall of the pool where the channel extends;

[0024] The waterproof layer is installed at the interface between the ditch and the side wall of the pool.

[0025] The beneficial effects of this invention are:

[0026] In terms of structure, this invention features direct openings in the pool wall, allowing for more direct stress on the pool wall compared to traditional interfaces. This also makes it easier to compact the surrounding soil to meet the bearing capacity requirements of the channel. The channel extends entirely into the side wall opening and is poured in one go, resulting in better waterproofing. Compared to traditional methods, there is no need to set up separate waterproof joints, reducing the need for processing steel bars and formwork support at the joints. The water-swellable waterstop strips and reinforcing bars on the side wall ensure the tightness and integrity of the connection with the pool side wall.

[0027] In terms of construction and economy, this invention can be selected according to the needs of the site; it can be modularized and standardized in processing and production, reducing the workload, reducing the processing of steel bars for the foundation layer and the formwork support, greatly increasing the convenience of construction, reducing the difficulty of construction, and shortening the construction cycle.

Those skilled in the art can determine the specific meaning of these terms in this invention based on the specific circumstances, and they should not be construed as limitations on the invention.

[0040] according to Figure 3 and Figure 4 This invention provides a construction method for the interface between a construction trench and a water tank sidewall, comprising:

[0041] Step 1: During the construction of the water tank 1, a hole with the outer dimensions of the channel is reserved in advance on the side wall 2 of the tank. A first sealing element is installed on the side wall to which the hole belongs, and a reinforcing bar 8 is reserved on the inner side of the side wall to which the hole belongs.

[0042] In specific implementation, the first sealing element is a water-swellable sealing strip or a sealing rubber strip.

[0043] Step 2: When the trench is constructed to the side wall of the pool, the bottom plate and side wall of the trench are directly made inside the opening of the side wall of the pool.

[0044] Step 3: Install a second seal around the perimeter of the pool sidewall 2 where it contacts the channel 9.

[0045] In practice, the second sealing element is a water-swellable sealing strip or a sealing rubber strip.

[0046] Step 4: Use the pre-reserved reinforcing bar 8 on the inner side of the side wall of the opening to tightly connect the channel and the pool wall.

[0047] Step 5: Extend the channel 9 into the side wall of the pool and make an inclined drip line 7 to prevent water in the channel from flowing directly into the pool and flowing through the gap between the channel and the pool wall.

[0048] Preferably, the angle of the drip line is 30 degrees.

[0049] It should be noted that in other embodiments, the angle of the drip line can be set according to the actual situation, which will not be described in detail here.

[0050] Step 6: Install a waterproof layer 6 at the interface between the ditch and the side wall of the pool to prevent water from seeping into the gap between the pool wall and the ditch when water flows back into the pool.

[0051] Furthermore, after the construction of the interface between the construction trench and the side wall of the pool is completed, backfill soil 5 is laid on the outside of the bottom plate 10 of the trench.

[0052] In one or more embodiments, at least one waterproof layer 6 is provided at the interface between the channel and the side wall of the pool.

[0053] This embodiment reduces the construction difficulty at the interface between the ditch and the pool sidewall, the binding of reinforcing bars, and the formwork support, thus improving construction efficiency. The backfill soil around the outer perimeter of the pool wall can be compacted in one go, meeting the bearing capacity requirements of the ditch. At the same time, it reduces the amount of reinforcing bars and concrete used for waterproof joints at the ditch and pool sidewall, saving costs. The integral pouring of the ditch reduces the number of joints and lowers the possibility of leakage. It simplifies the waterproofing process and improves construction efficiency.

[0054] according to Figure 4 This embodiment provides an interface structure between a construction trench and a water tank sidewall, which includes:

[0055] First seal, reinforcing rib, second seal, drip line and waterproof layer;

[0056] The first sealing element is installed on the side wall of the pool to which the opening belongs; the opening is pre-reserved on the side wall of the pool;

[0057] The tendon is pre-reserved on the inner side wall of the pool to which the opening belongs;

[0058] The second sealing element is embedded around the perimeter of the pool sidewall that contacts the channel; wherein the channel bottom plate and the pool sidewall are inside the opening in the pool sidewall;

[0059] The drip line is inclined and is set inside the side wall of the pool where the channel extends;

[0060] The waterproof layer is installed at the interface between the ditch and the side wall of the pool.

[0061] In one or more embodiments, the first sealing element is a water-swellable sealing strip or a sealing rubber strip. The second sealing element is a water-swellable sealing strip or a sealing rubber strip.

[0062] It should be noted that in other embodiments, the first and second seals may also be other existing sealing structures, which will not be described in detail here.

[0063] Preferably, the angle of the drip line is 30 degrees.

[0064] It should be noted that in other embodiments, the angle of the drip line can be set according to the actual situation, which will not be described in detail here.

[0065] To improve the waterproofing effect of the waterproof layer, the waterproof layer is at least one waterproof structure.

[0066] In terms of structure, this embodiment features direct openings in the pool wall, which allows for more direct stress on the pool wall compared to traditional interfaces. This also makes it easier to compact the surrounding soil to meet the bearing capacity requirements of the ditch. The ditch extends entirely into the side wall opening and is poured in one go, resulting in better waterproofing. Compared to traditional methods, there is no need to set up separate waterproof joints, reducing the need for processing reinforcing bars and formwork support at the joints. The water-swellable waterstop strips and reinforcing bars on the side wall ensure the tightness and integrity of the connection with the pool side wall.

[0067] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art.
