Detailed Description

The utility model is described in further detail below with reference to fig. 1-6. The following is provided to assist those skilled in the art in further understanding the present invention, but not to limit the present invention in any manner, and it should be noted that various changes and modifications can be made by those skilled in the art without departing from the spirit of the present invention, which falls within the scope of the present invention.

The utility model provides a prefabricated assembled ditch, includes cast-in-place bottom surface 1, corresponds to connect in the prefabricated lateral wall 2 of cast-in-place bottom surface 1 both sides, is located the top surface 3 on prefabricated lateral wall 2 to and be located the partition inner wall 4 between two prefabricated lateral walls 2, above-mentioned cast-in-place bottom surface 1, prefabricated lateral wall 2, top surface 3 and partition inner wall 4 all are reinforced concrete structure. In the actual construction process, a cushion layer 5 needs to be prefabricated, and the water channel is placed on the cushion layer 5.

The prefabricated side wall 2 comprises an extension bottom plate 21 positioned at the bottom and used for being connected with the cast-in-place bottom surface 1, a vertical side wall 22 positioned on the extension bottom plate 21, a tuck corner 23 positioned at the upper end of the vertical side wall 22 and between the vertical side wall 22 and the extension bottom plate 21, a limiting wall 24 positioned at the top of the vertical side wall 22 and used for limiting the top surface 3, and a waterproof groove 25 positioned on the extension bottom plate 21 and the limiting wall 24 and used for placing a water stop adhesive tape. In the actual work progress, prefabricated lateral wall 2 when the installation, need earlier accurate marking off on bed course 5, then make the accurate placing in bed course 5 relevant position of prefabricated lateral wall 2 through the mode of hoist and mount, and because prefabricated lateral wall 2's volume and weight are great, consequently at the in-process of hoist and mount, it is comparatively difficult to realize accurate positioning through the manpower, for solving above-mentioned problem, bottom surface at extension bottom plate 21 is equipped with two spacing bodies 26 that are used for injecing prefabricated lateral wall 2 position, specifically be a top for conical cylinder, when cast-in-place bed course 5, be equipped with the location blind hole 51 of an adaptation in the corresponding position of cylinder, when installing, only need with the cylinder place in location blind hole 51 can, greatly improved the efficiency of construction. In the preparation process of the positioning blind hole 51, the precise positioning is realized by adopting a secondary grouting mode, namely, a hole with a large range is reserved at the corresponding position of the cylinder, and then the precise position of the positioning blind hole 51 is determined in the hole. Adopt and extend bottom plate 21, reduce prefabricated lateral wall 2 focus, increased the area of contact between prefabricated lateral wall 2 and the bed course 5, make prefabricated lateral wall 2 when the installation, need not to adopt the support can realize placing steadily of prefabricated lateral wall 2, when preparing cast-in-place bottom surface 1 simultaneously, extend bottom plate 21 and play a template effect.

Longer canals are often subject to turning, and at this point the canals need to be prepared to a structure that accommodates the bend angle, i.e. prefabricated side walls need to be prepared to a structure with a certain curvature.

When preparing cast-in-place bottom surface 1, need set up the framework of steel reinforcement in the bottom, for making things convenient for the building of framework of steel reinforcement, be equipped with the connecting piece 27 that conveniently connects the framework of steel reinforcement on the extension bottom plate 21 of both sides, connecting piece 27 is including being located one or more in grout sleeve or threaded sleeve or the pre-buried short steel bar on the extension bottom plate of one side, and the grout sleeve or the pre-buried short steel bar that are located the opposite side extension bottom plate. The method for constructing the steel bar framework is characterized in that a grouting sleeve is arranged on one side of the threaded sleeve, and the other end of the grouting sleeve is inserted into the steel bar framework. If the form of pre-buried short steel bars is adopted, the connection can be realized by matching with a cold extrusion sleeve or a full grouting sleeve or a welding mode.

The partition inner wall 4 comprises a vertical inner wall 41, fluid corners 42 correspondingly arranged at the upper end and the lower end of the vertical

inner wall

41, and 2 supporting blocks 43 connected to the bottom surface of the vertical inner wall 41, wherein the supporting blocks 43 are provided with a plurality of through holes 44 for the steel bars to pass through, and a plurality of semicircular grooves 45 positioned at the bottom surface of the supporting blocks 43. Through being equipped with supporting shoe 43, make the cast-in-place bottom surface 1 that is located 4 both sides of partition inner wall be a whole, improved the holistic intensity of ditch, practice thrift the labour simultaneously (need not to install the framework of steel reinforcement many times), improved the efficiency of construction. Since the through hole 44 needs to be formed in the supporting block 43, and the supporting block 43 has no reinforcing steel bar structure therein, and is relatively brittle, when the supporting block 43 is relatively high, the supporting block 43 is more likely to be damaged, and therefore, the bottom surface of the supporting block 43 is provided with the plurality of semicircular grooves 45 while the through hole 44 is formed in the supporting block 43. Meanwhile, a pad plate 52 matched with the supporting block 43 is preset at a corresponding position of the cushion layer 5, so that the height of the pad plate 32 and the supporting block 43 does not exceed the height of the extension bottom plate 21.

The top surface 3 comprises laminated slabs 31 and cast-in-place top plates 32 positioned on the laminated slabs 31, wherein the laminated slabs 31 and the limiting walls 24 play a role of templates when the cast-in-place top plates 32 are prepared, and the construction period is greatly shortened.
