[0002] A sump is a temporary drainage facility used in construction projects to remove water accumulated in a foundation pit. It achieves groundwater drainage by combining a sump and a drainage ditch set at the bottom of the pit.

[0003] The existing technology includes a water storage mechanism with a filter mechanism installed inside. The opening of the water storage mechanism is covered with a sealing cap. The water storage mechanism includes a water collection well body. Two support parts are fixedly connected inside the water collection well body. The soil will enter the bottom of the water collection well body through the bottom filter element, while the clean water will be drawn out between the bottom filter element and the upper filter element, thereby improving the filtration rate of the water collection well.

[0004] The existing technology also has the following drawbacks: When carrying out the prefabrication of the water collection well, the silt soil usually has strong plasticity during the foundation construction. When constructing deep water collection wells or elevator shafts, the foundation pit support requires a huge investment and the construction period is particularly long. Utility Model Content

[0027] Example 1

[0028] Reference Figure 1 and Figure 2 This is the first embodiment of the present utility model. This embodiment provides a prefabricated device suitable for constructing water collection wells in silty soil layers, which can realize the industrialized mode of "immediate use after hoisting", transforming uncontrollable on-site operations into the effect of standardized factory prefabrication. It includes a main unit 100 and a prefabricated unit 200.

[0029] The main unit 100 includes a well body 101, and a stainless steel sleeve 102 is fixedly installed on the inner wall of the front end of the well body 101.

[0030] The prefabricated unit 200, which is provided on the side of the main unit 100, includes a prefabrication part 201 and an installation part 202 located on its side. The prefabrication unit 200 is used for prefabricating the water collection well.

[0031] When in use, by integrating and prefabricating the main structure and waterproofing of the water collection well, the construction time of the well structure and the waiting time for the connection between various processes are reduced. The well can be hoisted after the foundation pit is excavated, which reduces the exposure time of the foundation pit structure and safety risks, and further improves the construction period.

[0032] Example 2

[0033] Reference Figure 1 and Figure 2 This is the second embodiment of the present invention. Unlike the previous embodiment, the prefabricated part 201 includes a geotextile 201a fixedly connected to the bottom surface of the well body 101. A waterproof roll 201b is fixedly provided on the bottom surface of the geotextile 201a, and multiple wooden base plates 201c are stacked and fixedly provided on the bottom surface of the waterproof roll 201b.

[0034] Specifically, the installation part 202 includes an annular lifting channel steel 202a sleeved on the top surface of the well body 101, with four lifting rings 202b fixedly installed on the bottom surfaces of the four ends of the annular lifting channel steel 202a, and four bottom blocks 202c fixedly installed on the four ends of the well body 101.

[0035] In addition, four conical positioning piles 202d are fixedly installed on the bottom surface of the four bottom blocks 202c, and multiple prefabricated frames 202e are fixedly installed on the inner side and top surface of the four bottom blocks 202c.

[0036] When using it, the first step is to select a flat site near the main body 101 of the well for easy hoisting, and lay a wooden base plate 201c as the base layer for waterproofing the bottom of the main body 101 of the well. After laying a waterproof roll cloth 201b on the top of the template, lay a layer of protective waterproof geotextile 201a.

[0037] The waterproof roll fabric 201b has a 300mm wide waterproof flange at the edge. The flange and the self-adhesive waterproof membrane on the side wall are joined by hot melt to form a continuous sealing surface. The conical positioning pile 202d is an inverted conical steel component with a cone angle of 15°-30°. The surface of the pile body is provided with a rust-proof galvanized layer. The top of the pile is welded to the steel plate embedded in the bottom plate, and the pile tip is a detachable alloy steel head.

[0038] In addition, a pump pipe slot is provided on the inner side wall of the main body 101 of the well. A DN100 stainless steel sleeve 102 is pre-embedded in the slot. The axis of the sleeve is at a 5° angle to the horizontal plane. The surface of the self-adhesive waterproof membrane is laminated with a geotextile protective layer. The geotextile 201a has a weight of ≥400g / m². 2 .

[0039] In the second step of the process, the scope of this prefabrication is the well structure below -1.5m. The pre-made steel bars are tied together, and lifting rings and additional bars are pre-embedded at the top. A water-stop steel plate is welded to the top center of the wall. Then, the formwork is constructed according to the structural dimensions. After the formwork is reinforced, concrete is poured. After the structure is demolded, the outside of the well wall is treated, and the waterproof flange that was originally placed at the bottom is moved to the side wall. The structural concrete is cured to the design strength and awaits hoisting.

[0040] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
