[0026] The present invention will now be described in detail with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined with each other.

[0027] like Figure 1-5 As shown, a centralized mud station for use in a plateau wetland reserve includes a mud pit, a mud inlet device, and a mud return device. The mud station is located in the middle of 8-10 pier construction sites. The mud station is connected to each grouting and return platform 7 via multiple mud inlet pipes 4 and return pipes 5. The mud pit is divided into a mud preparation tank 2 and a mud storage tank 1 by a partition 8 in the middle. The mud station has a construction specification of 9.2m*21.3m and is reinforced with C20 cement mortar with a thickness of 20cm. The partition 8 is set at a distance of 5.5m. The partition 8 has a square hole 3 at a distance of 0.3m from the bottom of the mud pit as a flow outlet 3 with a size of 0.8m*0.8m. The partition 8 is constructed of brick and the surface is plastered with C20 cement mortar with a thickness of 25cm.

[0028] The slurry inlet device is installed in the slurry storage tank 1 and extends to the grouting return platform 7 through the slurry inlet pipe 4; the slurry return device is installed in the grouting return platform 7 and extends to the mud tank through the slurry return pipe. Both the slurry inlet pipe 4 and the slurry return pipe are mud hoses with a diameter of 125 mm and a wall thickness of 4 mm.

[0029] The outside of the mud pit is equipped with a sand filter tank 6 that connects to the return slurry pipeline and the slurry storage tank 1. The slurry returned from the injection return slurry platform 7 is filtered and settled. The filtered slurry is then recycled back into the slurry storage tank 1.

[0030] In this embodiment, the slurry feeding device and the slurry return device can be slurry pumps, and the slurry preparation tank 2 is equipped with a mixer for slurry preparation.

[0031] In an optional embodiment, a spiral feed pipe and a water inlet pipe are provided at one end of the mud tank near the pulping tank 2. The spiral feed pipe and the water inlet pipe are automatically controlled by a control system and a controller, so that automatic proportioning can be performed. This pulping equipment and method is a conventional technology and will not be described in detail here.

[0032] The pulping tank 2 is equipped with a mixer, and a flow port 3 connecting the pulping tank 2 and the pulp storage tank 1 is provided in the middle of the partition plate 8, so that the pulp produced can flow into the pulp storage tank 1 through the flow port 3.

[0033] In an optional embodiment, the grouting platform 7 includes a platform frame and a filter grid 701. The grouting platform 7 is a rectangular frame, and the platform frame is provided with a retaining plate 705 to form a collection trough corresponding to the cast-in-place pile. The retaining plate 705 is a metal plate with a bottom plate. Multiple retaining plates 705 are welded to form a trough-shaped body. The grouting platform 7 uses 20a I-beams 704, with a long side dimension of 3.7m and a short side dimension of 1.9m. A 1.7m long I-beam 704 is welded at the middle of the long side of the quadrilateral to form a support frame 702 corresponding to the cast-in-place pile reinforcement cage at one end of the platform frame. The I-beam 704 is cut at 45° bevels at both ends and fully welded to the platform frame to form a quadrilateral. This quadrilateral is used as... For the support frame 702, a filter grid 701 corresponding to the reinforcing cage of the cast-in-place pile is provided in the middle of the platform frame. The filter grid 701 can filter the grout during the grouting process, minimizing the blockage of the return pump by the gravel in the backflow grout. The filter grid 701 is a 16mm threaded steel welded steel mesh. The bottom of the collection tank is a closed end. An interface 703 corresponding to the pile hole of the cast-in-place pile is provided at the bottom of the collection tank. The interface 703 extends downward and into the opening of the pile hole. A sealing structure is provided to seal with the opening. The sealing structure can be a rubber sleeve or an inflatable rubber bladder. The inflatable rubber bladder is sleeved on the outer wall of the interface 703. By supplying air, the interface 703 and the inflatable rubber bladder form a seal, thereby ensuring that the grout overflows into the collection tank.

[0034] In an optional embodiment, the filter sand tank 6 and the slurry storage tank 1 share the same sidewall and are interconnected via an overflow port, which is a square notch. Multiple guide plates 9 are provided on the side of the filter sand tank 6 closest to the slurry storage tank 1. The length of each guide plate 9 is greater than three-fifths of the width of the filter sand tank 6, and the guide plates 9 are staggered on both sides of the filter sand tank 6. The elevation of the overflow port is lower than the elevation of the upper edge of the guide plates 9, thereby guiding the slurry through the guide plates 9 to settle, thus improving sedimentation efficiency and preventing sand and gravel from entering the slurry storage tank 1.

[0035] In an optional embodiment, a sedimentation plate is provided at the bottom of the sand filter tank 6, and a sedimentation trench is provided below the sedimentation plate. The sedimentation trench extends along the guide plate, and the sedimentation plate is correspondingly attached to the lower surface of the guide plate 9. The sedimentation plate can be a metal plate. During the flow process guided by the guide plate 9, the sand and gravel settle down to the bottom of the sedimentation plate. A sludge removal pipe is laid below the sedimentation plate in the sedimentation trench. The sludge removal pipe is a PVC pipe with a strip-shaped opening at the top, which is pre-embedded in the sedimentation trench to discharge the settled sand and gravel in a timely manner.

[0036] The side of the grouting and return platform 7 is equipped with a vertical frame corresponding to the return pump. The vertical frame is welded to the middle of the platform frame near the return platform. The return pump bracket is horizontally mounted and welded to the top of the vertical frame, which is used to install the return pump. Before construction, the mud pit is used for mud preparation, and the mud indicators are tested. When the pile foundation drilling begins on site, the grout pump is turned on, and the grout flows into the return platform of the grouting and return platform 7 along the grout inlet pipe 4. The square hole opened at the casing allows the grout to flow smoothly into the hole. Before the pile foundation grouting on site, the return pump and the filtration and sand removal system are turned on. During the pile foundation grouting on site, the grout flows from the grouting platform into the return platform and into the return pump, and flows into the mud pit storage tank along the return pipe. The grout in the storage tank enters the filtration system, is desanded, and flows into the storage tank. The whole process forms a closed loop, effectively avoiding the leakage of grout during construction and the problem of environmental pollution. At the same time, it effectively controls the performance indicators of the mud, improves the construction quality of the pile foundation, and realizes the recycling of mud, saving grouting materials. Significantly reduces the cost of transporting waste slurry and the expense of slurry preparation. Construction debris is easier to transport and dispose of, reducing environmental pollution.

[0037] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be within the scope of protection of the pending claims of the present utility model.
