Furthermore, the terms "first", "second", etc. are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first," "second," etc. may explicitly or implicitly include one or more of that feature. In the description of the invention, the meaning of "a plurality" is two or more unless otherwise specified.

In the description of the invention, it is to be noted that, unless otherwise explicitly specified or limited, the terms "mounted", "connected" and "connected" are to be construed broadly, e.g. as being fixed or detachable or integrally connected; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meaning of the above terms in the creation of the present invention can be understood by those of ordinary skill in the art through specific situations.

The invention will be described in detail with reference to the following embodiments with reference to the attached drawings.

A high-stability assembled prefabricated well chamber structure is shown in figures 1 to 8 and comprises a well bottom plate 1 and a well wall 2 arranged on the well bottom plate; the well bottom plate is provided with a fixed ring groove 3, the upper ends of the side walls at the two sides of the fixed ring groove are respectively provided with a step 4, the well bottom plate is provided with a plurality of water-blocking sealing holes 5 corresponding to the two sides of the fixed ring groove, and each water-blocking sealing hole is communicated with the fixed ring groove; still be equipped with a plurality of preformed holes 6 on the bottom plate of a well, can be with the help of preformed holes downward slip casting, also can wear to establish the anchor assembly (like reinforcing bar, stock etc.) that is used for the anchor in the anchor hole, carry out structural stability's enhancement to the bottom plate of a well.

In an optional embodiment, the water-blocking sealing hole comprises a vertical injection section 10, and an upper acting section 11 and a lower acting section 12 which are communicated with the injection section, wherein the upper acting section is communicated with the side wall of the fixed ring groove, and the lower acting section is communicated with the bottom of the fixed ring groove, so that the stability and the sealing property of the connection between the well wall and the well bottom plate are effectively improved.

Normally, a waterproof packing 13 is provided in the prepared hole to ensure waterproofness when the well bottom plate is used. When grouting or anchoring is needed, the waterproof filler is directly extruded downwards.

It should be noted that the waterproof packing is destroyed only under the working condition that the underground soil is soft and the well chamber is easy to be unstable, and then the anchor is grouted downwards or placed by the aid of the reserved hole. Thus, during grouting pressure or driving into the anchor, the waterproof plug is more easily crushed until it penetrates the soil below the floor of the well (because of the softer geology in this case).

In addition, during grouting, the general slurry is poured to the upper edge of the reserved hole, and at the moment, waterproof treatment is not needed; when the anchoring piece is put down, waterproof materials or mortar can be filled in the reserved hole to ensure the waterproofness of the reserved hole.

When this prefabricated well room structure of construction under the softer operating mode of soil property, can put into anchor assembly (can be 1 pair, also can be a plurality of to anchor assembly) in the preformed hole of symmetric position on the bottom plate of the well, then pour into the mortar in other preformed holes, the anchor combines with the slip casting, improves the firmness of bottom plate of the well greatly, ensures its application that also can be fine under the softer geological conditions of soil property.

The cross-section of the well wall may be circular or rectangular. Generally, water-blocking materials are injected into the water-blocking sealing holes and between the step and the well wall. The waterproof packing includes tar sand. And reserving 300-500 mm of transverse and longitudinal spacing between pouring holes.

According to actual need, when the wall of a well structure is fit for whole prefabrication, can support integral type structure with the wall of a well, and when the wall of a well structure is great, can adopt the formal design of assembling, as long as guarantee each assemble partial leakproofness and stability can. In an alternative embodiment, as shown in fig. 9, the well wall is formed by splicing a plurality of side wall plates 7 inserted into the fixing ring grooves, and mortar is injected into the fixing ring grooves during insertion, so that the stability of the side wall plates is improved, and the sealing performance between the side wall plates and the well bottom plate is also improved. In yet another alternative embodiment, as shown in fig. 10, the shaft wall may also be formed by splicing a plurality of shaft wall segments 8, and the bottom of the lowermost shaft wall segment is inserted into the fixed ring groove, i.e. embedded into the fixed ring groove, so as to improve stability and sealing performance.

In an alternative embodiment, in order to avoid air lock in the water-blocking sealing hole, as shown in fig. 5, a vertical vent hole 9 may be provided on the step corresponding to the water-blocking sealing hole, the vent hole is communicated with the water-blocking sealing hole, and when the water-blocking material is injected, the air can be exhausted through the vent hole, so as to ensure that the water-blocking material is compact and does not become empty. By way of example, the water-blocking material is waterproof dry-mixed mortar comprising cement mortar to which waterproof powder is added. Of course, those skilled in the art can also adopt other water-blocking materials according to actual needs. After the water-blocking material is filled, cement mortar is poured to the step, so that the upper part of the fixed ring groove is ensured to have good water resistance, and the well wall and the well bottom plate are more firmly fixed.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and should not be taken as limiting the invention, so that any modifications, equivalents, improvements and the like, which are within the spirit and principle of the present invention, should be included in the scope of the present invention.
