Description

Technical Field

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

[0002] During the construction process, after the foundation pit is excavated, a large amount of water often accumulates in the pit due to groundwater seepage, rainwater accumulation, and other reasons. If it is not drained in time, it will lead to the instability of the pit slope and muddy base, affecting the construction progress and safety. Therefore, pit drainage is a key link in foundation construction.

[0003] Currently, commonly used foundation pit drainage devices mostly employ a single water pump combined with a single drainage pipe. This involves placing one end of the drainage pipe into the waterlogged area and using the pump's suction to remove the water. However, this traditional device presents several problems in practical use: Firstly, because foundation pits are typically large, the water may be scattered across multiple areas. The coverage of a single drainage pipe is limited, requiring frequent repositioning of the device to achieve complete drainage, making operation cumbersome and inefficient. Secondly, a certain thickness of silt often accumulates at the bottom of the foundation pit. Traditional drainage pipe suction heads lack effective height adjustment mechanisms, easily sinking into the silt. This silt can then enter the pipes and pump, causing blockages, which not only affect drainage efficiency but also shorten the equipment's lifespan.

[0004] Therefore, it is necessary to design a foundation pit drainage device for building construction to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a foundation pit drainage device for building construction. This utility model has the advantages of flexible adjustment, efficient drainage, resistance to clogging, and ease of movement and maintenance.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A foundation pit drainage device for building construction includes a movable plate, a vertical plate fixedly connected to the upper end of the movable plate, a water pump installed on the movable plate, a multi-port pipe connected to the inlet end of the water pump, the multi-port pipe consisting of a main pipe and three branch pipes, each of the three branch pipes penetrating the vertical plate, each of the three branch pipes being equipped with a valve, each of the three branch pipes being threadedly connected to a connector, each of the three connectors having a flexible hose connected to its right side, and each of the three flexible hoses having a suction head connected to its lower end.

[0008] Preferably, the suction head includes a connecting sleeve, the lower end of which is fixedly connected to a flow guide, and the lower end of which is connected to a filter screen via a snap fastener.

[0009] Preferably, guide rails are fixedly connected to both the left and right sides of the connecting sleeve, and a movable ring is slidably connected to both guide rails. Multiple support feet are fixedly connected to the outer wall of the movable ring.

[0010] Preferably, the movable ring is threaded with two fixing bolts, and both guide rails are provided with multiple positioning holes.

[0011] Preferably, the lower end of the movable plate is equipped with a plurality of rollers, all of which are self-locking casters.

[0012] Preferably, the connecting sleeve, the flow guide, the moving ring, and the multiple legs are all made of stainless steel, and the legs are composed of an L-shaped rod and a rectangular plate.

[0013] Compared with existing technologies, the advantages of this device are:

[0014] 1. Compared with the existing technology, this device sets up three branch pipes through a multi-port pipe and cooperates with valve control. The number of drainage pipes to be installed can be flexibly selected according to the distribution of water in the foundation pit. When the water is dispersed, multiple drainage pipes can be used to expand the coverage area and improve drainage efficiency. When the water is concentrated, only some drainage pipes can be used to reduce energy waste. This solves the problem of fixed number of drainage pipes and poor adaptability of traditional devices.

[0015] 2. Compared with the existing technology, this device is equipped with a support foot at the suction head that can be adjusted in height by moving ring and fixing bolt. It can flexibly adjust the height of the suction head according to the depth of the silt at the bottom of the pit, effectively preventing the suction head from entering the silt and causing blockage. At the same time, with the protection of the guide hood and filter screen, the probability of impurities entering the pipeline is further reduced, the service life of the equipment is extended, and the situation of traditional devices being prone to blockage due to silt intake is improved.

[0016] 3. Compared with existing technologies, this device can be easily moved by the self-locking casters at the bottom of the moving plate, which can easily adapt to the complex ground environment in the foundation pit and facilitate quick transfer to different water accumulation areas; in addition, the connector adopts threaded connection and the filter screen is connected by snap-fit, which makes the disassembly and installation process simple and facilitates the cleaning and maintenance of components in the later stage, solving the problems of difficult movement and cumbersome maintenance of traditional devices.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figures 1-3 A foundation pit drainage device for building construction includes a movable plate 1. Multiple rollers 2 are installed at the lower end of the movable plate 1; all rollers 2 are self-locking casters. A vertical plate 15 is fixedly connected to the upper end of the movable plate 1. A water pump 3 is installed on the movable plate 1. The inlet end of the water pump 3 is connected to a multi-port pipe 4 via a flange. The multi-port pipe 4 is made of seamless steel pipe of DN50-DN80 welded together. The main pipe length is 300-400mm. The multi-port pipe 4 consists of a main pipe and three branch pipes. All three branch pipes pass through the vertical plate 15. Each of the three branch pipes is equipped with a valve 5, which is a DN50-DN80 ball valve with a cast iron body and a stainless steel stem. The operating handle is 100-150mm long, facilitating quick manual opening and closing and allowing precise control of the on / off state of each branch pipe. Each of the three branch pipes is threaded with a connector 6. A flexible hose 7 is connected to the right side of each of the three connectors 6. A suction head is connected to the lower end of each of the three flexible hoses 7.

[0023] The suction head includes a connecting sleeve 8, with a flow guide shroud 10 fixedly connected to the lower end of the connecting sleeve 8. A filter screen is connected to the lower end of the flow guide shroud 10 via a snap fastener. The flow guide shroud 10 has an inverted conical structure with a height of 150-200mm, a large opening diameter of 100-150mm, and a small opening diameter that matches the outer diameter of the connecting sleeve 8. An annular groove is provided on the lower edge of the flow guide shroud 10. The filter screen is made of stainless steel woven mesh with a pore size of 1-3mm and a wire diameter of 0.5-1mm. The edge is wrapped with stainless steel edging, and the edging has snap fastener protrusions that match the groove for easy disassembly, cleaning, or replacement.

[0024] The connecting sleeve 8 has guide rails 12 fixedly connected to both sides. A moving ring 11 is slidably connected to both guide rails 12. Multiple support feet 9 are fixedly connected to the outer wall of the moving ring 11. Two fixing bolts 14 are threaded through the moving ring 11. Multiple positioning holes 13 are provided on both guide rails 12. When the moving ring 11 slides to a suitable position, the fixing bolts 14 are screwed into the corresponding positioning holes 13 to achieve stable positioning of the moving ring 11.

[0025] Among them, the connector 6, the guide shroud 10, the moving ring 11 and the multiple support legs 9 are all made of stainless steel. The support legs 9 are composed of L-shaped rods and rectangular plates. This material has good corrosion resistance and mechanical strength, and makes the overall weight of the suction head relatively large, so as to prevent the suction head from moving when pumping water. It can adapt to the harsh environment of damp and dusty pits and extend the service life of the device. The support legs 9 are composed of L-shaped rods and rectangular plates, and the overall structure is stable, which can effectively support the suction head and prevent it from sinking into the silt.

[0026] The functional principle of this utility model can be explained through the following operation: First, according to the distribution of water accumulation in the pit, the movable plate 1 is pushed to a suitable position, and the number of drainage pipes installed is flexibly selected through the three branch pipes of the multi-port pipe 4. If the water accumulation is scattered, a flexible hose 7 and a suction head can be installed on the corresponding branch pipe through the connector 6, and the corresponding valve 5 can be opened; if the water accumulation is concentrated, only the required number of drainage pipes are installed and the remaining valves 5 are closed, thereby achieving drainage on demand and avoiding energy waste.

[0027] Secondly, regarding the depth of silt at the bottom of the pit, adjust the height of the support leg 9 at the suction head: loosen the fixing bolt 14 on the moving ring 11, slide the moving ring 11 up and down along the guide rail 12 to keep the suction head supported by the support leg 9 at an appropriate distance from the silt layer, tighten the fixing bolt 14 after adjustment, fix the position of the moving ring 11 through the positioning hole 13 to ensure that the suction head is stably in the clear water layer.

[0028] Finally, the water pump 3 is started, and the accumulated water enters the hose 7 through the suction head, and is then pumped out by the water pump 3 through the multi-port pipe 4. During use, if the filter screen needs to be cleaned, it can be quickly removed using the clips; if the hose 7 needs to be replaced or maintained, it can be easily disassembled and reassembled using the threaded connector 6, ensuring the continuous and efficient operation of the device.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
