Description

Technical Field

[0001] This utility model relates to the field of foundation pit support and water-blocking technology, and in particular to a foundation pit support and water-blocking device for building construction. Background Technology

[0002] In building construction, a foundation pit refers to a temporary or permanent earthwork excavation for the construction of underground structures (such as basements, foundations, underground utility tunnels, etc.). The main purpose of a foundation pit is to create a working surface for underground structures (foundations, pile foundations, basements, etc.), prevent soil collapse through support structures, ensure the safety of surrounding buildings, pipelines, and personnel, and prevent problems such as water seepage and quicksand through water-stopping measures.

[0003] In traditional building construction foundation pit support, methods such as pre-embedded pipes are generally used to divert seepage water. However, this method is relatively complex to construct and is not convenient for diverting and converging water flow. Based on this, a water-blocking device for building construction foundation pit support is proposed to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a water-blocking device for foundation pit support in building construction, which effectively solves the deficiencies of the prior art.

[0005] To achieve the above objectives, one embodiment of the present invention provides a water-blocking device for foundation pit support in building construction, including a support plate, wherein multiple anchor rods that enter the external soil are installed on the side of the support plate, and multiple water-permeable holes are provided on the side of the support plate near the anchor rods, and the multiple water-permeable holes form a group. A water collection box is installed on the side of the support plate near the water permeable hole. A connecting pipe is provided between multiple water collection boxes in the vertical direction. A water collection trough is installed at the bottom of the support plate. A water collection pit is installed on the bottom surface of the water collection trough. Multiple through holes are opened on the bottom wall of the water collection trough near the water collection pit. The inside of the water collection pit is equipped with steel grating, and the top of the water collection pit is equipped with a protective plate. A water pump is installed on one side of the top surface of the protective plate, and a water pipe is installed at the input end of the water pump, which enters the inside of the water collection pit.

[0006] Preferably, in any of the above schemes, multiple reinforcing seats are installed on the side of the support plate near the anchor bolt, and stiffening plates are installed between the edges of the multiple reinforcing seats and the support plate. This scheme can increase the structural strength of the support plate near the anchor bolt, avoid deformation under stress later, and the multiple reinforcing seats can enhance the compressive strength of the support plate. The multiple anchor bolts are stably installed at the edge of the pit to provide stable support for the edge of the pit.

[0007] Preferably, in any of the above solutions, both sides of the multiple water collection boxes are fixedly connected to the support plate by bolts, and a filter screen is provided between the sides of the multiple water collection boxes and the support plate. In this solution, the water collection boxes are preferably made of plastic, which is easy to injection mold, economical, lightweight, easy to transport and assemble on site, and easy to disassemble and clean later. The filter screen is convenient for filtering the leaked water and preventing mud and sand from entering the interior of the water collection pit.

[0008] Preferably, in any of the above solutions, the bottom ends of the multiple connecting pipes are located directly above the water collection tank, and the multiple connecting pipes are fixedly connected to the water collection box by adhesive. This solution facilitates the vertical connection of multiple water collection boxes, allowing water to flow downwards and enter the interior of the water collection tank to collect the water. Corrugated pipes are preferred for the connecting pipes, as they have a certain degree of flexibility, which facilitates on-site installation by operators. They can also be cut to the appropriate length as needed, improving the ease of installation.

[0009] Preferably, in any of the above-mentioned schemes, support blocks are installed at the top of all four sides of the inner wall of the sump. The steel grating is located on the top surface of multiple support blocks. In this scheme, multiple support blocks facilitate the installation of the steel grating. At the same time, the steel grating is an open metal plate made of flat steel and crossbars (usually twisted square steel or round steel) welded or press-locked. It has the characteristics of high strength, lightweight, light transmission and ventilation, anti-slip, good corrosion resistance, and effectively prevents personnel or debris from falling. It also allows operators to easily observe the water level inside the sump through the steel grating. The steel grating has a slot reserved near the water pipe of the water pump input end, which facilitates the water pipe to enter the bottom of the sump through the slot, and then facilitates the operation of the water pump to pump out the water inside the sump.

[0010] Preferably, in any of the above solutions, the top surface of the protective plate near the water pump has a notch, and the top surface of the protective plate is flush with the top surface of the water collection tank. This solution facilitates providing a gap for the water pipe at the water pump input end, avoiding interference between the two. The protective plate can also cover the exposed part of the water collection tank, providing stable support for the operators and facilitating the construction of the foundation pit.

[0011] This utility model has the following advantages: 1. This construction pit support and water-blocking device, by setting up a support plate with multiple water-permeable holes on its side, a water collection box is fixedly connected to the support plate and covers the multiple water-permeable holes. Water around the support plate enters the interior of the water collection box through the water-permeable holes, then enters the interior of the water collection tank through the connecting pipe, and flows into the interior of the water collection pit. By energizing and operating a water pump, the water inside the water collection pit is pumped out, thereby achieving the purpose of water treatment. The overall structure is simple, the design is reasonable, and it effectively solves the problems existing in the prior art.

[0012] 2. This construction pit support and water-blocking device uses a support plate and multiple anchor rods, with the anchor rods extending into the external soil, to facilitate stable support of the pit by the support plate. A water collection box with a filter screen between it and the support plate is installed to filter the outflowing water and prevent mud and sand from entering the water collection pit. The water collection box can be disassembled to facilitate cleaning and replacement of the filter screen and cleaning of the permeable holes, thus avoiding any impact on the outflow of water.

Multiple water-permeable holes 10 are opened on the side of the support plate 1 near the anchor rods 6, and the multiple water-permeable holes 10 form a group. A water collection box 7 is installed on the side of the support plate 1 near the water permeable hole 10. A connecting pipe 8 is provided between multiple water collection boxes 7 in the vertical direction. A water collection trough 5 is installed at the bottom of the support plate 1. A water collection pit 4 is installed on the bottom surface of the water collection trough 5. Multiple through holes 12 are opened on the bottom wall of the water collection trough 5 near the water collection pit 4. The water collection pit 4 is equipped with a steel grating 9 inside, and a protective plate 2 is installed on the top of the water collection pit 4. The water collection pit 4 and the protective plate 2 can be made of stainless steel, which has high corrosion resistance. The protective plate 2 covers the exposed part of the water collection pit 4, making it easy to disassemble the protective plate 2 later to observe the condition inside the water collection pit 4 and clean the fire pile steel grating 9. A water pump 3 is installed on one side of the top surface of the protective plate 2, and a water pipe is installed at the input end of the water pump 3, which enters the interior of the water collection pit 4.

[0017] The material of the support plate 1 is generally steel sheet pile or steel formwork, which has good bending and compressive strength, is simple to process and construct, and can be pulled out and recycled later, making it highly economical.

[0018] Multiple reinforcing seats 11 are installed on the side of the support plate 1 near the anchor rod 6. Stiffeners are installed between the edges of the multiple reinforcing seats 11 and the support plate 1. As an optional technical solution of this utility model, this can increase the structural strength of the support plate 1 near the anchor rod 6 and avoid deformation under stress in the later stage. At the same time, the multiple reinforcing seats 11 can enhance the compressive strength of the support plate 1. The multiple anchor rods 6 are stably installed at the edge of the foundation pit to provide stable support for the edge of the foundation pit.

[0019] Both sides of the multiple water collection boxes 7 are fixedly connected to the support plate 1 by bolts. Filter screens are provided between the sides of the multiple water collection boxes 7 and the support plate 1. As an optional technical solution of this utility model, the material of the water collection boxes 7 should preferably be plastic, which is easy to injection mold, economical, lightweight, easy to transport and assemble on site, and easy to disassemble and clean later. The filter screen can filter the leaked water and prevent mud and sand from entering the interior of the water collection pit 4.

[0020] The bottom ends of multiple connecting pipes 8 are all located directly above the water collection tank 5. The multiple connecting pipes 8 are fixedly connected to the water collection box 7 by adhesive. As an optional technical solution of this utility model, this facilitates the vertical connection of multiple water collection boxes 7, allowing water to flow downwards and enter the interior of the water collection tank 5 to collect the water flow. At the same time, corrugated pipes are preferred for the connecting pipes 8, as they have a certain degree of expansion and contraction performance, which facilitates on-site installation by operators. In addition, the pipes can be cut to the appropriate length as needed to improve the convenience of installation.

[0021] Support blocks 13 are installed at the top of the four sides of the inner wall of the sump 4. The steel grating 9 is located on the top surface of the multiple support blocks 13. As an optional technical solution of this utility model, the multiple support blocks 13 facilitate the installation position of the steel grating 9. At the same time, the steel grating 9 is an open metal plate made of flat steel and crossbars (usually twisted square steel or round steel) welded or pressed and locked. It has the characteristics of high strength, lightweight, light transmission and ventilation, anti-slip, good corrosion resistance, and effectively prevents personnel or debris from falling. It also allows operators to easily observe the water level inside the sump 4 through the steel grating 9. The steel grating 9 has a slot reserved near the water pipe position of the water pump 3 input end, which facilitates the water pipe to enter the bottom position of the sump 4 through it. Then it is easy to control the operation of the water pump 3 to pump out the water inside the sump 4.

[0022] The protective plate 2 has a notch on its top surface near the water pump 3. The top surface of the protective plate 2 is flush with the top surface of the water collection tank 5. As an optional technical solution of this utility model, this makes it easier to provide a gap for the water pipe at the input end of the water pump 3, avoiding interference between the two. The protective plate 2 can cover the exposed part of the water collection tank 4, providing stable support for the operators and facilitating the operators to carry out the foundation pit construction.

[0023] This type of foundation pit support and water-blocking device for building construction requires the following steps when used: 1) During use, the support plate 1 is fixedly connected by multiple anchor bolts 6; 2) Water in the soil enters the interior of the water collection box 7 through multiple permeable holes 10, and then enters the interior of the water collection trough 5 through the connecting pipe 8; 3) The water flows along the water collection trough 5 into the water collection pit 4 for temporary storage; 4) Powering on water pump 3 will pump the water out of the sump 4.

[0024] In summary, during use, a support plate 1 is installed, with multiple permeable holes 10 on its side. A water collection box 7 is fixedly connected to the support plate 1, covering the permeable holes 10. Water around the support plate 1 enters the water collection box 7 through the permeable holes 10, then flows through the connecting pipe 8 into the water collection trough 5, and finally into the water collection pit 4. The water pump 3, powered on, pumps out the water from the water collection pit 4, thus achieving water treatment. The overall structure is simple, rationally designed, and effective. To effectively solve the problems existing in the prior art, the support plate 1 and multiple anchor rods 6 are used to extend into the external soil, thereby facilitating the stable support of the foundation pit by the support plate 1. By setting up a water collection box 7, a filter screen is installed between the water collection box 7 and the support plate 1, which facilitates the filtration of the outflowing water and prevents mud and sand from entering the water collection pit 4. At the same time, disassembling the water collection box 7 facilitates the cleaning and replacement of the filter screen and the cleaning of the water permeable hole 10, thus avoiding any impact on the outflow of water.
