Description

Technical Field

[0001] The invention relates to the technical field of empty box construction, in particular to an empty box one-time grouting construction device and a method thereof. Background Art

[0002] Empty box is a kind of beam in bridge engineering, which is hollow inside. It is mainly used in the process of waterway regulation construction. On-site construction mainly places the empty box at the predetermined foundation pit position, and then performs concrete grouting operation at the bottom of the empty box, so that the bottom of the empty box is wrapped with concrete, thereby ensuring the subsequent stability of the empty box. However, there are still some problems with the existing empty box grouting construction device, as follows:

[0003] The existing empty box grouting construction device mainly pours concrete on the edges of the foundation pit and the empty box after the empty box is completely placed in the foundation pit position, so that the empty box and the foundation pit are connected and fixed. However, this method of grouting results in concrete pouring only at the joint gap between the empty box and the bottom of the foundation pit. There is no other concrete pouring structure around the empty box to serve as an auxiliary support. The construction and installation of the empty box is completed only by landfilling after the subsequent installation of the empty box. There is no relatively restrictive structure between the empty box and the earth to make the empty box more firmly confined in the earth. Such strength makes it difficult to ensure the installation position strength of the empty box.

Then the external concrete pouring device is started again to pour concrete until the concrete rises to the top of the metal pipe and stops, and then the concrete is solidified.

[0023] The present invention has the following beneficial effects:

[0024] 1. The one-time grouting construction device and method for an empty box are as follows: a bottom shell is placed in a foundation pit, and top blocks are respectively arranged and installed on both sides of the foundation pit. The supporting assembly placed in the bottom shell is combined with the supporting assembly as its supporting part so that the empty box can be spaced apart from the inside of the bottom shell after being placed on the supporting assembly. Then, concrete is poured from the conduit into the inside of the bottom shell through an external grouting device. At the same time, the supporting assembly will slowly shrink so that the empty box gradually moves downward, thereby causing the bottom of the empty box to gradually contact with the concrete poured inside the bottom shell. During the downward movement of the empty box, the concrete poured inside the bottom shell can be compacted and leveled. In addition, in the presence of the supporting assembly, after the empty box is completely and stably placed in the bottom shell, its bottom end is also spaced apart from the inside of the bottom shell. This can greatly increase the contact area of ​​the concrete filled between the empty box and the bottom shell, thereby greatly increasing the subsequent installation stability of the empty box.

[0025] 2. The one-time grouting construction device and method for an empty box are provided with a limiting straight bar with a notch. The limiting straight bar can be used to limit the rotation of the support assembly before it moves to its notch, thereby ensuring the stability of the empty box in the process of the support assembly contracting and driving the empty box to descend. After descending to the notch position, the adjustment assembly can synchronously drive multiple straight rods to rotate, so that the support assembly drives the supporting assembly to slowly descend during the rotation process until the bottom of one end of the supporting assembly contacts and stops with the inside of the bottom shell, and then the driving assembly drives the straight rod to move up and take out the entire support assembly, and after taking out the support assembly, a metal pipe is placed at the original position of the straight rod, the bottom of the metal pipe will contact the inside of the edge block, and then concrete will continue to be poured into the bottom shell. After the concrete inside the bottom shell is filled, it will rise straightly from the side edge block along the metal pipe to form a concrete column located on the side of the empty box, and then after the subsequent backfilling of earth, the connection strength between it and the earth can be strengthened, thereby ensuring the stable installation of the empty box.

DETAILED DESCRIPTION

[0037] The technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the present invention. In addition, the forms of the various structures recorded in the following embodiments are only examples. The empty box one-time grouting construction device and method involved in the present invention are not limited to the various structures recorded in the following embodiments. All other embodiments obtained by ordinary technicians in this field without making creative work belong to the scope of protection of the present invention.

[0038] See also Figure 1 , an empty box one-time grouting construction device, comprising a bottom shell 1 and a top block 2, a side block 3 is installed on the side of the bottom shell 1, the top block 2 is fixedly placed on the side soil, a support assembly 4 is movably installed in the side block 3, limited straight bars 5 are fixedly installed on both sides of the top of the bottom shell 1, a supporting assembly 6 is movably arranged on the support assembly 4, a connecting kit 7 is sleeved on the top of the support assembly 4, a hydraulic pump station 8 is fixedly installed on the top of the top block 2, an adjusting assembly 9 is fixedly installed on one side of the top block 2, a driving assembly 10 is fixedly installed on the bottom end of the adjusting assembly 9, a guide tube 11 is fixedly installed on the side of the bottom shell 1, and the top of the guide tube 11 is fixedly connected to an external concrete pouring device;

[0039] In the present invention, a bottom shell 1 is placed in the foundation pit, and then top blocks 2 are respectively arranged and installed on both sides of the foundation pit. The supporting assembly 6 placed in the bottom shell 1 and the supporting assembly 4 as its supporting part can make the empty box be spaced apart from the inside of the bottom shell 1 after being placed on the supporting assembly 6. Then, concrete is poured into the inside of the bottom shell 1 from the conduit 11 through the external grouting equipment. At the same time, the supporting assembly 4 will also slowly shrink to make the empty box gradually move downward, so that the bottom of the empty box gradually contacts with the concrete poured inside the bottom shell 1. In the process of the downward movement of the empty box, the concrete poured inside the bottom shell 1 can be compacted and flattened. In the presence of the supporting assembly 6, after the empty box is completely and stably placed in the bottom shell 1, its bottom end is also spaced apart from the inside of the bottom shell 1. In this way, the contact area of ​​the concrete filled between the empty box and the bottom shell 1 can be greatly increased, thereby greatly increasing the installation stability of the subsequent empty box. At the same time, a limiting straight bar 5 with a notch is provided. The strip 5 can limit the rotation of the support assembly 4 before it moves to its notch, thereby ensuring the stability of the empty box during the process of the support assembly 4 contracting and driving the empty box to descend. After descending to the notch position, the adjustment assembly 9 can synchronously drive multiple straight rods 45 to rotate, so that the support assembly 4 drives the supporting assembly 6 to slowly descend during the rotation until the bottom of one end of the supporting assembly 6 contacts and stops with the inside of the bottom shell 1, and then the driving assembly 10 drives the straight rod 45 to move up and take out the entire support assembly 4. After the support assembly 4 is taken out, a metal pipe is placed at the original position of the straight rod 45. The bottom of the metal pipe will contact the inside of the edge block 3, and then concrete will continue to be poured into the bottom shell 1. After the concrete inside the bottom shell 1 is filled, it will rise straight from the side edge block 3 along the metal pipe to form a concrete column located on the side of the empty box, and then after the subsequent backfilling of earth, the connection strength between it and the earth can be strengthened, thereby ensuring the stable installation of the empty box.

[0040] See also Figure 1 and Figure 5 , an empty box one-time grouting construction device, comprising a bottom shell 1, an extension plate is arranged at the top edge of the bottom shell 1, the bottom end of the guide tube 11 is connected with the extension plate, the end position of the extension plate can be relatively movable and sealed with the empty box, an empty groove is opened inside the side block 3, and the empty groove is connected with the bottom shell 1, a truncated cone structure is arranged in the empty groove of the side block 3, and a through groove is opened between the side and top surfaces of the truncated cone, and a metal pipe can be placed on the truncated cone inside the side block 3;

[0041] In this embodiment, it should be noted that, through the concrete pouring device, the concrete can be poured into the bottom shell 1 through the conduit 11, and then the thickness between the bottom shell 1 and the empty box gradually increases. In this way, after the metal pipe is placed on the side block 3, the continuously poured concrete will enter the side block 3 from the side, and then enter the metal pipe with the height gradually increasing until it stops after pouring to the top of the metal pipe. In this way, after the internal concrete is completely solidified, a reinforced support auxiliary concrete column can be formed between the periphery of the empty box and the subsequent backfill earthwork, thereby improving the overall installation stability of the empty box.

[0042] See also Figure 7-10 , an empty box one-time grouting construction device, including a support assembly 4, the support assembly 4 includes a hydraulic telescopic rod 41, the hydraulic telescopic rod 41 is connected to a hydraulic pump station 8 through an oil pipe, a turntable 42 is movably installed on the top of the hydraulic telescopic rod 41, a roller 43 is movably installed on the side of the turntable 42, a limit column 44 is fixedly installed on the end of the roller 43, a straight rod 45 is fixedly installed on the top of the turntable 42, and a connecting kit 7 is rotatably sleeved on the outer surface of the straight rod 45;

[0043] In this embodiment, it should be noted that the bottom end of the hydraulic telescopic rod 41 is placed and installed on the round table of the side block 3, the turntable 42 and the top end of the hydraulic telescopic rod 41 are rotatably arranged, the roller 43 is rotatably supported at the bottom of the supporting assembly 6, and the straight rod 45 is provided with a uniform annular groove, and the top end of the straight rod 45 is provided with a non-circular groove. The straight rod 45 can be driven to rotate by the adjusting assembly 9 when the empty box needs to be completely lowered, so that the roller 43 rotates to the corresponding position on the supporting assembly 6, and then the supporting assembly 4 is driven by the adjusting assembly 9 to be pulled upward from the bottom as a whole, so as to ensure that the subsequent metal pipe can be placed normally therein, and to ensure that a concrete column can be formed around the empty box to enhance the installation stability of the empty box.

[0044] See also Figure 4 and Fig. 9 , an empty box one-time grouting construction device, comprising a supporting assembly 6, the supporting assembly 6 comprising a supporting block 61, a bottom end of the supporting block 61 is provided with a bottom groove 62, an extension block 63 is fixedly mounted on the supporting block 61, and a bottom ring 64 is fixedly mounted above the supporting block 61;

The limiting straight bar 5 is movably arranged in the slot, and the U-shaped internal width of the limiting straight bar 5 is equal to the diameter of the limiting column 44 Before the rotation occurs, the limit column 44 is set in a limit position in the area jointly formed by the extension block 63 and the limit straight bar 5. In this way, during the downward movement of the supporting block 61, the limit straight bar 5 will move inside the extension block 63, so that the notch part on the limit straight bar 5 will move relative to the extension block 63. When the notch part moves to the middle of the extension block 63, the limit column 44 will be released from the restriction. At this time, the straight rod 45 can be driven to rotate by the top adjustment component 9, thereby driving the limit column 44 to rotate, so that the roller 43 will roll at the bottom end of the bottom ring 64, and when it reaches the inclined part, it can also make the supporting block 61 further descend while rotating until the bottom end of the supporting block 61 contacts the inside of the bottom shell 1, so that the subsequent concrete pouring can enter the side block 3 from the feed trough on the side of the bottom groove 62, and then form a concrete column upward in the metal pipe, thereby ensuring the stable installation of the empty box.

[0047] The lower bottom plate 91 and the upper top plate 92 are movably connected to each other so as to move up and down. The lower bottom plate 91 and the upper top plate 92 are arranged to slide relative to each other. The position of the driving wheel 94 at the lower end of the upper top plate 92 corresponds to the position of the side block 3, and one of the driving wheels 94 is fixedly connected to the output shaft of the external drive motor 93. The bottom end of the driving wheel 94 is provided with a protrusion adapted to the non-circular groove opened at the top of the straight rod 45. The two ends of the first hydraulic rod 96 are respectively fixedly connected to the lower bottom plate 91 and the upper top plate 92, so that when it is necessary to drive the straight rod 45 to rotate, the driving wheel 94 can be driven to rotate by the external drive motor 93, and the driving wheel 94 can be inserted into the groove set by the straight rod 45 by adjusting the driving assembly 10, thereby driving the straight rod 45 to rotate, so that the supporting assembly 6 is separated from its support and falls into the bottom shell 1 after the roller 43 rotates, and then the supporting assembly 4 can be taken out as a whole, which is convenient for the subsequent insertion of the metal pipe.

[0050] A method for using an empty box one-time grouting construction device is as follows:

[0051] S1, place the bottom shell 1 into the foundation pit, then place the support assembly 4 into the side block 3, then lower the support assembly 6 through the straight rod 45 to the top of the support assembly 4, and then install the top block 2 on the land on the side of the foundation pit;

[0052] S2, hoist the empty box above the foundation pit, and then lower it to the upper end of the supporting block 61, start the hydraulic pump station 8, the hydraulic pump station 8 makes the hydraulic telescopic rod 41 in the foundation pit slowly contract, driving the empty box to slowly descend, and at the same time, the external concrete pouring device pours concrete into the bottom shell 1 through the conduit 11.

[0053] S3, start the first hydraulic rod 96, the first hydraulic rod 96 makes the lower bottom plate 91 move as a whole in the direction of the straight rod 45, start the external drive motor 93, and at the same time start the second hydraulic rod 1003 to extend, so that the two linkage gears 1009 are engaged, and then the adjustment component 9 is driven to move downward on the top block 2 as a whole through the straight rod 45, and at the same time start the second hydraulic rod 1003 to contract, so that the two linkage gears 1009 are separated and opened, and the external drive motor 93 drives the driving wheel 94 to rotate, and then drives the straight rod 45 to rotate, so that the limit column 44 and the roller 43 will rotate accordingly, when the limit column 44 and the roller 43 rotate to the grooves opened on the bottom ring 64 and the support block 61, the support block 61 will directly fall into the bottom shell 1, and its bottom end will contact with the bottom shell 1 to form support for the empty box;

[0054] S4, start the first hydraulic rod 96 again to contract, so that the driving gear 1010 moves to both sides of the straight rod 45, then start the second hydraulic rod 1003 to extend, so that the two driving gears 1010 clamp the straight rod 45, start the side drive motor 1008, the side drive motor 1008 drives the driving gear 1010 to rotate, so that the straight rod 45 moves upward, and finally the support assembly 4 is taken out as a whole.
