Detailed Description
The invention is described in detail below with reference to the figures and specific embodiments. The present embodiment is implemented on the premise of the technical solution of the present invention, and a detailed implementation manner and a specific operation process are given, but the scope of the present invention is not limited to the following embodiments.
Fig. 1-fig. 3 show a settlement-preventing type cement pole reinforced foundation under soft geology such as sand or silt, for the assembled foundation, mainly comprise two parts, firstly cement pole sleeve 1, secondly supplementary disc 2, both adopt the assembly mode to realize the settlement-preventing of cement pole 3, cement pole sleeve 1 is hollow cylindrical, the bottom of cement pole sleeve 1 is airtight, the open-top of cement pole sleeve 1, and the open-top of cement pole sleeve 1 turns up there is annular turn-over edge 11, the through-hole 21 with cement pole sleeve 1 matched with is seted up to the center department of supplementary disc 2.
During the use, supplementary disc 2 is located on ground 4, the through-hole 21 embedding ground 4 that supplementary disc 2 was passed to 1 bottom of cement pole sleeve, and 11 cards of annular edge turning are on supplementary disc 2, cement pole 3 inserts and fixes in cement pole sleeve 1, cement pole sleeve 1 and supplementary disc 2 all adopt reinforced concrete structure, when cement pole 3 received external load's effect, cement pole sleeve 1 and supplementary disc 2 combined action resist 3 side direction of cement pole and topple moment and vertical load.
Compared with the conventional sleeve foundation, the cement rod sleeve 1 is additionally provided with an upper protruding part, namely an annular turned edge 11, the main function of the cement rod sleeve is to be in butt joint with the auxiliary disc 2, so that the weight of a rod body is transferred to a part of the auxiliary disc 2 through the protruding part, and the settlement under a soft foundation is reduced.
Meanwhile, according to the practical situation of engineering, different sizes of the cement rod sleeve 1 and the auxiliary disc 2 are selected, and the cement rod sleeve can be widely applied to various rod type foundations. The auxiliary disc 2 is divided into an integral type and an assembled type and is selected according to the actual engineering situation.
