Detailed Description
The present application is described in further detail below with reference to figures 1-4.
An assembled inspection well connecting structure, as shown in fig. 1, comprises a well body 1 and drain pipes 2 arranged on the peripheral surface of the well body 1 and mutually installed with the well body 1.
As shown in fig. 2, the well body 1 is a concrete pipe, the lower end of the well body 1 is arranged for sealing, the well body 1 is vertically arranged underground, three caulking grooves 11 are uniformly formed in the upper end face of the well body 1 by taking the central line of the well body 1 as an axis, a lapping ring 12 is arranged in each caulking groove 11, the lapping ring 12 is welded and fixed with the reinforcing steel bars inside the well body 1, and the lapping ring 12 does not protrude out of the surface of the caulking groove 11, so that workers can fix the lapping ring 12 with each other through a rope, and then hoist the well body 1, thereby improving the convenience of hoisting the well body 1, and the lapping ring 12 does not protrude out of the surface of the caulking groove 11, and the longitudinal building of the well body 1 cannot be influenced.
As shown in fig. 3, a plurality of butt joint pipes 3 are horizontally arranged on the circumferential surface of the well body 1 (the number of butt joint pipes 3 in this embodiment is taken as an example), the axial lines of the butt joint pipes 3 are perpendicular to the axial line of the well body 1, and the butt joint pipes 3 and the well body 1 are prefabricated integrally.
As shown in fig. 3, the drain pipe 2 is a prefabricated pipe fitting made of concrete, the diameter of the outer peripheral surface of the drain pipe 2 is equal to the diameter of the inner wall of the butt joint pipe 3, and when the drain pipe 2 and the butt joint pipe 3 are mutually inserted, one end of the drain pipe 2 is inserted into the butt joint pipe 3, so that the outer wall of the drain pipe 2 is tightly attached to the inner wall of the butt joint pipe 3. The outer peripheral surface of the drain pipe 2 is also provided with an annular sealing plate 21, the plane of the annular sealing plate 21 is perpendicular to the central line of the drain pipe 2, and the annular sealing plate 21 is welded with the steel bars inside the drain pipe 2 when the drain pipe 2 is prefabricated, so that the annular sealing plate 21 protrudes out of the outer peripheral surface of the drain pipe 2 after concrete is poured and solidified. Annular shrouding 21 leaves the distance with drain pipe 2 grafting one end for behind drain pipe 2 and the mutual grafting of butt joint pipe 3, butt joint pipe 3 terminal surface supports and leans on one side at annular shrouding 21. A plurality of bolts 22 are arranged on the annular closing plate 21 in a penetrating way, and the bolts 22 are uniformly distributed along the outline of the annular closing plate 21. And the end surface of the butt joint pipe 3 is provided with a matching pipe 31 at the position corresponding to each bolt 22, the matching pipe 31 is prefabricated in the butt joint pipe 3, and the axis of the matching pipe 31 is parallel to the axis of the butt joint pipe 3. The bolt 22 is matched with the bolt 22 of the matching pipe 31, so that the drainage pipe 2 and the butt joint pipe 3 are fixed with each other more firmly.
As shown in fig. 4, a sleeve 4 is prefabricated on the inner wall of the port of the butt joint pipe 3, the axis of the sleeve 4 is coincident with the axis of the butt joint pipe 3, the diameter of the inner wall of the sleeve 4 is equal to that of the inner wall of the butt joint pipe 3, and one end face of the sleeve 4 is flush with the end face of the butt joint pipe 3. When the drain pipe 2 and the butt joint pipe 3 are inserted into each other, the sleeve 4 is attached to the outer peripheral surface of the drain pipe 2. Three ring grooves 42 are formed in the inner circumferential surface of the sleeve 4 along the axial direction of the sleeve 4, a plurality of partition plates 43 are respectively arranged in each ring groove 42 at intervals along the annular direction of the ring groove 42, and the edge of each partition plate 43 is fixedly connected with the inner wall of the ring groove 42, so that the ring grooves 42 are divided into a plurality of separation chambers 44 with the same size. The peripheral surface of the butt joint pipe 3 is provided with a plurality of glue injection ports 45 which are mutually communicated with the ring grooves 42, and the number of the glue injection ports 45 corresponds to the proper amount of the separation chambers 44 one by one.
After drain pipe 2 and butt joint pipe 3 pegged graft each other, one edge of baffle 43 and drain pipe 2 outer wall are leaned on each other, the staff pours into every compartment 44 sealed glue through every injecting glue mouth 45, because the space of compartment 44 inside is far less than the size of annular 42, make sealed glue can be abundant fill in into compartment 44, sealed glue is the waterproof sealed glue of purchasing now on the market, form the sealing layer in the gap to pipe 3 and drain pipe 2 after sealed glue solidifies, thereby greatly increased the sealing performance between drain pipe 2 and the butt joint pipe 3, the difficult condition of leaking takes place, and then the difficult soil horizon around causing the well body 1 appears collapsing.
As shown in fig. 4, the number of the partition plates 43 in each ring groove 42 is the same, but the fixing positions are different, so that even if liquid enters a gap between the partition plate 43 and the drain pipe 2, the liquid cannot smoothly pass through each ring groove 42 due to the distribution positions of the partition plates 43, and the leakage of the liquid is greatly hindered. And 3 gaps are respectively arranged on the edge of each clapboard 43 facing the drain pipe 2. When the sealant is injected into each compartment 44, the redundant glue flows into the adjacent compartments 44 through the gap, so that the gap between the partition plate 43 and the drain pipe 2 is filled, and the sealing performance between the drain pipe 2 and the butt joint pipe 3 is greatly improved.
