Description

Technical area

[0001] The present utility model relates to the technical field of pile foundation construction and, in particular, to a sludge collection structure for pile foundation construction. State of the art

[0002] Mud is an important tool when drilling pile foundation holes. Its main functions include the following: Cooling and lubrication: During the drilling process, the mud can dissipate the heat generated by the hole wall and cuttings, providing a cooling effect. It can also lubricate the drill bit and hole wall, reducing friction and extending the life of the drill bit.

[0003] Crushing and suspending cuttings: The sand-bearing particles in the mud help to crush the surrounding rock, suspend and remove the cuttings generated during drilling, and prevent the cuttings from clogging the borehole.

[0004] Maintaining the stability of the borehole wall: The mud can withstand the pressure of the formation, maintain the stability of the borehole wall, and prevent borehole collapse and difficulty in excavation.

[0005] In certain cases, it can be used to seal the borehole and improve the stability of the borehole wall.

[0006] It transports the rock created during drilling, maintains the mud flow and keeps the borehole bottom clean, etc.

[0007] Therefore, pumping out the sludge is often necessary during construction. However, the current technology does not provide a special sludge collection structure, so the bottom surface of the pile foundation borehole is often flooded with sludge, polluting the construction site and deteriorating the construction environment. Summary of the utility model

[0008] The purpose of the present utility model is to provide a mud collection structure for the pile foundation hole construction method, which enables convenient mud collection and prevents the ground surface of the construction site from becoming slippery.

[0009] The embodiments of the present utility model are realized by the following technical solutions.

[0010] A sludge collection structure for the pile foundation hole construction includes a collection basin, the collection basin being adapted to the pile foundation hole and disposed at one side of the pile foundation hole; and a connecting channel communicating with the collection basin is disposed at the upper end of the pile foundation hole.

[0011] Furthermore, a bottom plate is arranged on the top of the collecting basin; and the bottom plate has a drain hole corresponding to the upper opening of the collecting basin, so that the drain hole is directly opposite the upper opening of the collecting basin when the bottom plate on the collecting basin is covered.

[0012] Furthermore, the base plate also covers the top of the pile foundation hole; and the base plate has a through hole corresponding to the pile foundation hole, so that when the base plate is covered on top of the pile foundation hole, the through hole is directly opposite the top opening of the pile foundation hole.

[0013] Furthermore, the hole diameter of the drain hole is smaller than the upper opening of the collecting basin; and the hole diameter of the drain hole is 300 mm.

[0014] Furthermore, the hole diameter of the drain hole is larger than the upper opening of the collecting basin.

[0015] Furthermore, a waterproof film is arranged in the collecting basin.

[0016] Furthermore, an inner insert is provided in the collecting basin; the inner insert is designed in the shape of a barrel; and a cutout corresponding to the connecting channel is arranged on the side surface of the inner insert.

[0017] The technical solution of the embodiment of the present utility model has at least the following advantages and useful effects.

[0018] When the sludge trap structure is used for the pile foundation hole construction of the present utility model, the sludge in the pile foundation hole overflows into the catch basin via the connecting channel once the sludge reaches the connecting channel. The sludge can be pumped out of the catch basin using a sludge pump. Because the connecting channel is positioned deeper than the ground surface, the sludge from the pile foundation hole can flow into the catch basin without reaching the ground surface, effectively preventing the sludge from overflowing the pile foundation hole and making the ground slippery.

[0021] To more clearly illustrate the objectives, technical solutions, and advantages of the embodiments of the present utility model, the technical solutions of the embodiments of the present utility model will be described clearly and completely below with reference to the accompanying drawings. It should be understood that the described embodiments represent some, but not all, embodiments of the present utility model. The components described and illustrated in the figures may be arranged and configured in various configurations. Examples

[0022] As in the Fig. 1-3, the present utility model provides a slurry trapping structure for the pile foundation hole construction method, comprising a trap basin 1. The trap basin 1 is fitted to the pile foundation hole 2 and arranged laterally adjacent to the pile foundation hole 2. The pile foundation hole 2 is gradually drilled from the surface to the depth. The trap basin 1 is also gradually excavated from the surface to the depth. The trap basin 1 can be arranged at any location around the pile foundation hole 2. However, the distance between the two should not be too large; ideally, the net distance is a maximum of one meter. At the top of the pile foundation hole 2, a connecting channel 3 is arranged, which communicates with the trap basin 1. The connecting channel 3 is actually a trench formed on the ground, the purpose of which is to connect the pile foundation hole 2 and the trap basin 1.The depth of the collection basin 1 is preferably 1.5 m.

[0023] When the sludge trap structure is used for the pile foundation hole construction method of the present utility model, the sludge in the pile foundation hole 2 overflows into the catch basin 1 via the connecting channel 3 once the sludge reaches the connecting channel 3. The sludge can be pumped out of the catch basin 1 by a sludge pump. Since the connecting channel 3 is located below the ground surface, the sludge from the pile foundation hole 2 can flow into the catch basin 1 without reaching the ground surface, effectively preventing the sludge from leaking out of the pile foundation hole 2 and polluting the construction site.

[0024] In practice, the retention basin 1 and the pile foundation hole 2 can be excavated first. The excavation of retention basin 1 can be done by drilling or manually.

[0025] In this embodiment, a base plate 4 is arranged on the collecting basin 1. As in Fig. 1, the bottom plate 4 is arranged with a drain hole 5 corresponding to the upper opening of the collecting basin 1, so that the drain hole 5 is directly opposite the upper opening of the collecting basin 1 when the bottom plate 4 is covered on top of the collecting basin 1.

[0026] The base plate 4 can be a thick steel plate or something else. After the base plate 4 is laid, it covers the ground area around the catch basin 1. Without the base plate 4, the area between the pile foundation hole 2 and the catch basin 1 could collapse due to repeated movements by workers. At the same time, this area is usually muddy ground, which can wet the ground if mud spills. The installation of the base plate 4 makes the ground between the pile foundation hole 2 and the catch basin 1 more stable. At the same time, the mud spilled on the reinforced base plate 4 is not particularly slippery, which increases safety. In addition, the base plate 4 covers the edge of the catch basin 1, leaving only the drain hole 5 for mud drainage, which better isolates the mud from the ground.

[0027] In this embodiment, the base plate 4 is further covered above the pile foundation hole 2. The base plate 4 is provided with a through hole 6 corresponding to the pile foundation hole 2, so that the through hole 6 is directly opposite the upper opening of the pile foundation hole 2 when the base plate 4 is placed on the pile foundation hole 2. This allows the base plate 4 to also cover the edge of the pile foundation hole 2, thus ensuring better protection of the soil area.

[0028] In this embodiment, the hole diameter of the drain hole 5 is smaller than the upper opening of the collecting basin 1. The hole diameter of the drain hole 5 is 300 mm. As in Fig. 3, most of the upper surface of the catch basin 1 is covered by the base plate 4, creating a larger working surface that is more advantageous for construction.

[0029] In this embodiment, the hole diameter of the drain hole 5 can also be larger than the upper opening of the catch basin 1. This is more suitable for open-air construction sites. The completely open upper surface of the catch basin 1 makes it easier for personnel to observe the sludge and thus pump it out in a timely manner.

[0030] In this embodiment, a waterproof film is arranged in the collection basin 1. The waterproof film isolates the sludge from the collection basin 1 and prevents the bottom of the collection basin 1 from mixing with the sludge and impairing its quality.

[0031] In this embodiment, an inner liner 7 is provided in the collection basin 1. The inner liner 7 is designed in the shape of a barrel. A recess 8 is arranged on the side surface of the inner liner 7, which corresponds to the position of the connecting channel 3. The inner liner 7 can be welded from steel plates, so that the inner liner 7 can be reusable. The inner liner 7 also isolates the sludge from the collection basin 1 and prevents the soil from mixing with the sludge and impairing the quality of the sludge.

[0032] The foregoing merely represents a preferred embodiment of the present utility model and is not intended to limit the utility model. Various modifications and alterations to the present utility model may be made by those skilled in the art. Any modifications, adaptations, and improvements within the spirit and basic principles of this utility model are intended to be included within the scope of the utility model.

[0033] The present utility model relates to the technical field of pile foundation hole construction and provides a sludge collection structure for the pile foundation hole construction, which includes a collection basin. The collection basin is adapted to the pile foundation hole and is arranged on one side of the pile foundation hole. A connecting channel is arranged at the upper end of the pile foundation hole and communicates with the collection basin. When the sludge collection structure for the pile foundation hole construction of the present utility model is used, the sludge in the pile foundation hole overflows into the collection basin via the connecting channel once the sludge reaches the connecting channel. The sludge can be pumped out of the collection basin using a sludge pump.Since the connecting channel is below the ground surface, the sludge from the pile foundation hole can flow into the catch basin without reaching the ground surface, which effectively prevents the sludge from flowing over the pile foundation hole and polluting the construction site.
