[0001] The utility model relates to the technical field of integrated prefabricated pumping stations, in particular to an anti-floating and anti-pulling support for an integrated prefabricated pumping station. Background Art
[0002] As a lifting device for lifting sewage, rainwater, drinking water, wastewater, etc., the integrated prefabricated pumping station has the advantages of convenient installation, high integration, unattended operation and low maintenance cost, and has a broad market prospect. Generally, it is prefabricated and assembled in a factory and then transported to the site for buried installation; however, for an integrated pumping station with a large diameter and a large burial depth, the anti-floating property is poor, and when affected by the buoyancy of groundwater, the buried pumping station is prone to overall floating due to insecure bottom fixation or damage of anti-floating components; secondary embedded repair is required, which increases the labor cost and maintenance cost.
[0003] Therefore, how to provide an anti-floating and anti-pulling support for an integrated prefabricated pumping station, which can improve the overall anti-floating ability of the pumping station and increase the bottom stability of the pumping station, is an urgent problem to be solved by those skilled in the art. Summary of the Utility Model
[0004] In view of this, the utility model provides an anti-floating and anti-pulling support for an integrated prefabricated pumping station, aiming to solve the technical problems of insecure bottom connection and poor overall anti-floating ability of the traditional integrated pumping station with a large diameter and a large burial depth.
[0005] In order to achieve the above object, the utility model adopts the following technical scheme:
[0006] The utility model provides an anti-floating and anti-pulling support for an integrated prefabricated pumping station, and the bottom end of the pumping station barrel has a groove; including:
[0007] A concrete foundation, which is arranged at the lower end of the pumping station barrel, and its upper end face covers the notch of the groove to form a casting cavity for filling concrete inside the groove; a casting through hole communicating with the casting cavity is arranged on the outer peripheral wall of the bottom of the pumping station barrel;
[0008] An anchor rod, the lower end of which is embedded in the concrete foundation, and the upper end of which is located above the concrete foundation;
[0009] An anti-floating and anti-pulling support; the anti-floating and anti-pulling support is fixedly installed on the outer peripheral wall of the bottom of the pumping station barrel and is fixedly connected with the upper end of the anchor rod;
[0010] Wherein, a concrete layer is cast and formed at the upper end of the concrete foundation corresponding to the outer periphery of the pumping station barrel; the filling concrete in the casting cavity and the casting through hole is integrally formed with the concrete layer.
[0011] When the integrated precast pump station anti - floating and anti - pulling support of the present utility model is in use, the anti - floating and anti - pulling support is pre - fixed on the pump station barrel body. A concrete foundation is cast at the installation position of the precast pump station, and anchor bolts are embedded during the casting of the concrete foundation. After the concrete foundation is cured, the pump station barrel body is placed on the upper end of the concrete foundation, and the anti - floating and anti - pulling support is fixedly connected to the upper end of the anchor bolt, so that the pump station barrel body is stably installed on the concrete foundation.

[0014] As a further improvement of the above - mentioned technical solution, the anti - floating and anti - pulling support is a triangular connecting piece.
[0015] The beneficial effect of the above - mentioned technical solution is that the triangular anti - floating and anti - pulling support can further improve the anti - floating and anti - pulling ability.
[0016] As a further improvement of the above - mentioned technical solution, the concrete foundation is a reinforced concrete foundation slab.
[0017] The beneficial effect of the above - mentioned technical solution is that the concrete foundation adopts a reinforced concrete foundation slab, and the structure is more stable.
[0018] As a further improvement of the above - mentioned technical solution, the pouring through - hole corresponds to the upper part of the pouring cavity; the upper surface of the concrete layer is located above the pouring through - hole.
[0019] The beneficial effect of the above - mentioned technical solution is that the pouring through - hole corresponds to the upper part of the pouring cavity, which is more conducive to grouting. The upper surface of the concrete layer is located above the pouring through - hole, that is, the thickness of the concrete layer covers the pouring through - hole, so that the filling concrete poured in the pouring through - hole can be better connected with the concrete layer.
[0020] As a further improvement of the above technical solution, it further includes reinforcing bars inserted through, the inserted reinforcing bars penetrate through the pouring through holes, and one end thereof is fixedly inserted in the concrete layer, and the other end is fixedly inserted in the filled concrete in the pouring cavity.
[0021] The beneficial effect of the above technical solution is that by inserting reinforcing bars through the pouring through holes, the connection strength between the filled concrete in the pouring cavity and the concrete layer can be further enhanced.
[0022] As can be seen from the above technical solution, compared with the prior art, the integrated precast pump station anti-floating and anti-pulling support disclosed by the present utility model has the following advantages and beneficial effects:
[0023] 1.

[0033] A concrete foundation 1, the concrete foundation 1 is arranged at the lower end of the pumping station barrel 4, and its upper end face covers the notch of the groove 41 to form a casting cavity for filling concrete inside the groove 41; a casting through - hole 42 communicating with the casting cavity is opened on the outer peripheral wall at the bottom of the pumping station barrel 4;
[0034] An anchor rod 2, the lower end of the anchor rod 2 is embedded in the concrete foundation 1, and its upper end is located above the concrete foundation 1;
[0035] An anti - floating and anti - pulling support 3; the anti - floating and anti - pulling support 3 is fixedly installed on the outer peripheral wall at the bottom of the pumping station barrel 4 and is fixedly connected to the upper end of the anchor rod 2;
[0036] Wherein, a concrete layer 11 is formed by casting at the upper end of the concrete foundation 1 corresponding to the outer periphery of the pumping station barrel 4; the filling concrete 5 in the casting cavity and the casting through - hole 42 is integrally formed with the concrete layer 11.
[0037] When the integrated precast pump station anti - floating and anti - pulling support of this embodiment is in use, the anti - floating and anti - pulling support 3 is pre - fixed on the pump station barrel 4. The concrete foundation 1 is cast at the installation position of the precast pump station, and the anchor bolts 2 are embedded during the casting of the concrete foundation 1. After the concrete foundation 1 is cured, the pump station barrel 4 is placed on the upper end of the concrete foundation 1, and the anti - floating and anti - pulling support 3 is fixedly connected to the upper end of the anchor bolt 2, so that the pump station barrel 4 is stably installed on the concrete foundation 1. Concrete is poured into the pouring cavity through the pouring through - hole 42, and a concrete layer 11 is cast secondarily on the upper end of the concrete foundation 1 corresponding to the outer peripheral side of the pump station barrel 4, so that the concrete layer 11 completely covers the anti - floating and anti - pulling support 3, and the concrete layer 11 is fixedly connected as a whole with the filling concrete 5 in the pouring cavity and the pouring through - hole 42. The concrete structure integrally penetrated through the pouring through - hole 42 inside and outside the bottom of the pump station barrel 4 makes it more firmly connected to the concrete foundation 1, which can greatly improve the overall anti - floating ability of the pump station and increase the stability of the bottom of the pump station.
[0038] Specifically, the diameter of the pump station barrel 4 is from 1 m to 8 m.
[0039] In some embodiments, both the anti - floating and anti - pulling support 3 and the anchor bolt 2 are multiple. The multiple anti - floating and anti - pulling supports 3 are evenly distributed along the circumferential direction of the pump station barrel 4; the multiple anchor bolts 2 are fixedly connected to the multiple anti - floating and anti - pulling supports 3 one by one.
[0040] The multiple anti - floating and anti - pulling supports 3 being evenly distributed along the circumferential direction of the pump station barrel 4 further improves the stability and anti - floating ability of the bottom of the pump station.
[0041] Specifically, when form - working and casting the concrete foundation 1, the multiple anchor bolts 2 are pre - buried and installed in place, and the installation positions of the multiple anchor bolts 2 are determined according to the outer contour structure and size of the bottom of the pump station barrel 4.

The anti - floating and anti - pulling support 3 includes a horizontal bottom plate 31, a vertical plate 32 vertically fixed on one side of the top end of the horizontal bottom plate 31, and a reinforcing plate 33 vertically fixed on the top end of the horizontal bottom plate 31 and vertically fixed on the side of the vertical plate 32; the vertical plate 32 of the anti - floating and anti - pulling support 3 is fixedly connected to the peripheral wall of the pump station barrel 4 through a connecting bolt 34; the anchor bolt 2 is a pre - embedded anchor bolt, its lower end is hook - shaped and pre - embedded in the concrete foundation 1, and its upper end is a screw end and is fastened through a nut after passing through the through - hole of the horizontal bottom plate 31 of the anti - floating and anti - pulling support 3, so as to press - fix the horizontal bottom plate on the upper end of the concrete foundation 1. The triangular anti - floating and anti - pulling support 3 can further improve the anti - floating and anti - pulling ability.
[0043] In some embodiments, the concrete foundation 1 is a reinforced concrete foundation slab, which is made with reference to the existing technology. Using a reinforced concrete foundation slab for the concrete foundation 1 makes the structure more stable.
[0044] In some embodiments, the pouring through-hole 42 corresponds to the upper part of the pouring cavity; the upper surface of the concrete layer 11 is located above the pouring through-hole 42.
[0045] The pouring through-hole 42 corresponding to the upper part of the pouring cavity is more conducive to grouting. The upper surface of the concrete layer 11 is located above the pouring through-hole 42, that is, the thickness of the concrete layer 11 covers the pouring through-hole 42, so that the filling concrete poured in the pouring through-hole 42 can be better connected with the concrete layer 11.
[0046] In some embodiments, it further includes a reinforcing bar (not shown in the figure) passing through. The reinforcing bar passes through the pouring through-hole 42, and one end of it is fixedly inserted into the concrete layer 11, and the other end is fixedly inserted into the filling concrete 5 in the pouring cavity.
[0047] Inserting a reinforcing bar through the pouring through-hole 42 can further strengthen the connection strength between the filling concrete 5 in the pouring cavity and the concrete layer 11.
