Description

Prefabricated mould of water conservancy diversion mound

Technical Field

The utility model relates to the technical field of prefabricated assembly, in particular to a prefabricated die for a flow guide pier.

Background

When the water delivery flow is increased in large-scale diversion and water diversion engineering, obvious karman vortex street phenomenon can appear at the downstream of the buildings such as partial bridge pier, aqueduct, inverted siphon and the like, thereby causing turbulence and restricting water diversion capability. Therefore, the structure of the building needs to be optimized and modified, and the karman vortex street phenomenon is eliminated by adding a diversion structure and the like at the upstream of the building, so that the water delivery capacity is improved. In addition, because the diversion and water regulation engineering has larger scale, wide involvement area, high investment cost for water cut-off reconstruction and large economic loss, the diversion construction reconstruction can only be carried out under the condition of normal water delivery. However, the newly added diversion building has large volume and weight, and in order to reduce the construction difficulty, shorten the construction period, save the construction cost and ensure the construction safety, the proposal of splicing and sinking into place can be adopted by adopting factory prefabricated components on the water surface.

The inventor knows a modularized flow guiding pier (CN 216920189U), which is a modularized flow guiding pier structure formed by a precast concrete empty box structure, wherein the flow guiding pier structure is divided into a plurality of sections along the water flow direction and a plurality of layers along the height, the sections are connected through high-strength bolts, and the top view of the flow guiding pier structure is in an acute isosceles triangle structure; the lowest precast concrete empty box structure of each section comprises a bottom plate, a surrounding side plate and a middle cavity, grouting holes are formed in the bottom plate, and secondary grouting holes are formed in the side plates along the vertical direction; each layer of precast concrete empty box structure above the lowest layer in each section comprises a vertical through hollow box body structure formed by surrounding side plates, and secondary grouting holes are also formed in the side plates on each layer of precast concrete empty box structure above the lowest layer in each section, and the secondary grouting holes of each section vertically correspond to and are communicated with each other.

However, in the process of realizing the technical scheme in the embodiment of the utility model, the inventor finds that when the diversion pier is prefabricated and poured, because the interlayer rabbet is an inclined ladder opening and a corresponding ladder seat, when the interlayer bolt connecting hole is reserved by adopting the embedded sleeve, the embedded sleeve needs to extend out of the ladder opening or the ladder seat for a certain length in order to ensure the smooth insertion of the connecting bolt in the later period, and after the prefabrication is finished, the embedded sleeve which is protruded at the position corresponding to the ladder opening and the ladder seat of the prefabricated block needs to be removed by adopting equipment such as lifting, cutting and the like, so that the interlayer splicing is avoided, wherein when the rabbet of the embedded sleeve is removed along the ladder opening or the inclined plane of the ladder seat, the cutting equipment is easy to mistakenly damage the pier body, and when the cutting is incomplete, the interlayer tight alignment is easy to be blocked, so that the interlayer gap is caused.

In order to realize accurate positioning of the side die 5 and the inner die 6 and avoid influencing the molding quality of the guide pier, in the example, referring to fig. 2, reinforcing die supports 9 are welded on the outer surfaces of the side die 5 and the inner die 6 along the vertical direction, wherein the side die and the reinforcing die supports 9 of the inner die are arranged in pairs, screw slots are respectively formed in two ends of the reinforcing die supports 9 and used for placing screws 10 therein, positioning between the reinforcing die supports 9 is realized through nuts screwed on the screws 10, in the example, the nuts are respectively arranged on two sides of the reinforcing die supports 9, and the nuts at two ends of the reinforcing die supports 9 are used for clamping and fastening the nuts at two ends of the reinforcing die supports, so that the distance between the side die 5 and the inner die 6 can be reliably adjusted and limited and fixed. In addition, since the two ends of the fixed die support 9 extend out of the corresponding side die or side die by a certain length respectively, thereby interfering with the bottom die, in this embodiment, in order to ensure the stability of pouring the die, the bottom of the bottom die 7 is provided with a base, and the position of the base corresponding to the fixed die support 9 is provided with a through hole for penetrating the screw 10, thereby eliminating interference between the reinforced die support 9 and the bottom die 7.

In addition, the prefabricated partition block of the bottom layer of the flow guide pier is provided with a bottom plate relative to other prefabricated partition blocks, because the bottom plate is poured, the reinforcing die supports 9 of the inner die 6 cannot extend out of the bottom of the prefabricated partition block of the flow guide pier and are connected with the reinforcing die supports 9 corresponding to the side dies 5 through screws, and therefore, when the prefabricated block of the bottom layer of the flow guide pier is poured, inner dies of different structures need to be replaced, the end parts of the reinforcing supporting rods 9 of the inner dies positioned at the bottom layer of the prefabricated partition block do not extend out of inner die side lines, and a plurality of hydraulic rods are distributed among the inner dies at the cavity of the flow guide pier in a crossing mode, and the bottom of the inner dies is supported and limited through the hydraulic rods.
