Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of building construction, specifically, a civil engineering grid for municipal building engineering. BACKGROUND

[0002] The key nodes of urban drainage and water conservancy engineering are faced with the problems of water flow entraining sundries, water quality purification and bank slope protection. As for the rainwater inlet, as the first station of surface runoff into the drainage pipe network, sundries such as leaves, branches and plastic garbage are easily accumulated. Once these sundries lack effective interception, they will quickly block the drainage pipeline, reduce the drainage efficiency, and even cause waterlogging during heavy rainfall, seriously affecting urban traffic, residents' life and infrastructure safety. The traditional rainwater inlet design lacks the ability to intercept sundries, and it is difficult to meet the drainage demand. The unique vertical installation of the grid structure and arrangement can vertically intercept large sundries at the rainwater inlet, ensuring smooth drainage.

[0003] Considering that when installing the prefabricated bottom plate, first drill a hole at the bottom of the rainwater inlet, use expansion bolts or chemical anchors to firmly fix the base at the specified position, ensure that the base is tightly fitted with the bottom of the rainwater inlet, and then install the grid at the bottom, but the soil at the bottom of the ditch may become loose due to long-term water flow scouring. If the rain is heavy at this time, a large amount of rainwater forms turbulent flow, which will have a more violent impact on the loose soil at the bottom of the ditch, accelerating soil loss, causing the base under the grid to be further hollowed out, which will not only weaken the stability of the grid, but also may cause displacement, tilting or even collapse. UTILITY MODEL CONTENTS

[0004] The utility model aims at solving the above-mentioned shortcomings and providing a civil engineering grid for municipal building engineering.

[0005] To achieve the above-mentioned purpose, the utility model provides a civil engineering grid for municipal building engineering, which comprises a base body, a plurality of vertical grids are inserted at the top of the base body, a plurality of arc-shaped buffer frames are fixedly connected to the surface of the vertical grid, and a fixing assembly is arranged at the top of the base body.

[0006] The fixing assembly comprises a plurality of positioning grooves opened at the top of the base body, a positioning load-bearing block is inserted into the inner wall of the positioning groove, the inner wall of the positioning groove and the surface of the positioning load-bearing block are connected in an insertion fitting mode, and part of the surface of the positioning load-bearing block extends out of the inner wall of the base body through the positioning groove.

[0007] As a further improvement of the technical solution, a plurality of connection grooves are formed on the surface of the vertical grid, and a connecting rod is fixedly inserted into the inner wall of the connection groove.

[0008] As a further improvement of the technical solution, the connecting rod is fixedly connected with a limiting rod at both ends.

[0009] The limiting rod is located on one side of the vertical grille.

[0010] As a further improvement to this technical solution, a positioning column is fixedly connected to the bottom of the base body, and two positioning columns are arranged as a group, symmetrically distributed with the bottom of the base body as the center.

[0011] As a further improvement to this technical solution, the surfaces of multiple arc-shaped buffer frames are all arc-shaped.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] In this municipal construction project, the vertical grid is inserted into the base body for quick installation and disassembly, adapting to different rainwater inlet sizes. An arc-shaped buffer frame is fixed to the surface of the vertical grid to disperse water pressure and reduce direct impact. Simultaneously, the positioning groove in the fixing component is connected to the positioning load-bearing block via an interlocking mechanism. The positioning load-bearing block, with its significant weight, applies downward vertical pressure to the base body, firmly fixing it to the ground and effectively preventing displacement under external forces such as water flow impact and ground vibration, ensuring the stable operation of the entire drainage system.

[0022] With reference to the drawings of the embodiments of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described, obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative labor are within the protection scope of the present application.

[0023] Embodiment

[0024] Please refer to Figures 1-4 The embodiment provides a civil engineering grid for municipal building engineering, which comprises a base body 1, a plurality of vertical grids 11 are inserted into the top of the base body 1, a plurality of arc-shaped buffer frames 3 are fixedly connected to the surface of the vertical grids 11, and a fixing assembly 2 is arranged on the top of the base body 1.

[0025] The fixing assembly 2 comprises a plurality of positioning grooves 21 arranged on the top of the base body 1, positioning bearing blocks 22 are inserted into the inner walls of the positioning grooves 21, the inner walls of the positioning grooves 21 and the surface of the positioning bearing blocks 22 are connected in a plug-in cooperation mode, and part of the surface of the positioning bearing blocks 22 extends out of the inner wall of the base body 1 through the positioning grooves 21.

[0026] By installing the base body 1 at the rainwater inlet, a plurality of vertical grids 11 are installed on the top of the base body 1, then, the positioning bearing blocks 22 are aligned with the positioning grooves 21, with the help of a specific tool, the positioning bearing blocks 22 are gradually inserted into the positioning grooves 21, so that part of the surface of the positioning bearing blocks 22 extends out of the inner wall of the base body 1 through the positioning grooves 21, until the bottom of the positioning bearing blocks 22 is in contact with the ground, then, a continuous force is applied to make the positioning bearing blocks 22 continue to move downward, until the surface of the positioning bearing blocks 22 is completely in contact with the top of the base body 1, at this time, the positioning bearing blocks 22 exert a vertical downward pressure on the base body 1 by virtue of its large weight, and the base body 1 is firmly fixed on the ground, which effectively prevents the base body 1 from being displaced under the action of external forces such as water flow impact and ground vibration, thereby ensuring that the vertical grid 11 is always in a stable working state.

[0027] The improvement of the embodiment is that:

[0028] Considering that when installing the prefabricated base, first drill a hole at the bottom of the rainwater inlet, use expansion bolts or chemical anchors to firmly fix the base at the designated position, ensure that the base is tightly fitted with the bottom of the rainwater inlet, and then install the bottom grille, but the soil at the bottom of the ditch may become loose due to long-term water flow, and if the rain is heavy at this time, a large amount of rainwater will form a turbulent flow, which will further impact the loose soil at the bottom of the ditch, accelerating soil loss, causing the foundation under the grille to be further hollowed out, which will not only weaken the stability of the grille, but also may cause displacement, tilt or even collapse, therefore, by inserting the vertical grille 11 into the base body 1, it is convenient for quick installation and disassembly, and it is suitable for different rainwater inlets, and the arc-shaped buffer bracket 3 is fixedly installed on the surface of the vertical grille 11, which can disperse the water flow pressure and reduce the direct impact on the vertical grille 11. At the same time, the positioning groove 21 and the positioning load block 22 in the fixing assembly 2 are connected in a plug-in cooperation mode, and the positioning load block 22 exerts a vertical downward pressure on the base body 1 by virtue of its own large weight, firmly fixing the base body 1 on the ground, effectively preventing displacement under the action of external forces such as water flow impact and ground vibration, and ensuring stable operation of the entire drainage facility.

[0029] In order to make the multiple vertical grilles 11 installed on the top of the base body 1 into a whole, and make them more stable when filtering rainwater, therefore, the surface of the multiple vertical grilles 11 is provided with a connecting groove 110, and a connecting rod 12 is fixedly plugged into the inner wall of the connecting groove 110; the connecting rod 12 is inserted into and fixed to the inner wall of the connecting groove 110, and through this connection mode, the connecting rod 12 realizes the connection of the multiple vertical grilles 11 into a whole structure, effectively enhancing the connection strength and cooperative working performance between the multiple vertical grilles 11, so that the vertical grilles 11 can resist external forces as a stable whole when facing water flow impact and other external forces.

[0030] In order to make the pressure borne by the vertical grille 11 when filtering rainwater not all borne by the base body 1, therefore, the connecting rod 12 is fixedly connected with a limiting rod 120 at both ends;

[0031] The limiting rod 120 is located on one side of the vertical grille 11; a groove matching the surface of the limiting rod 120 is formed on the side of the rainwater inlet, and at this time, the limiting rod 120 is inserted into the inner wall of the groove, and at this time, when rainwater passes through the vertical grille 11, the limiting rod 120 will support the vertical grille 11 longitudinally, avoiding that all impact forces are borne by the base body 1.

[0032] In order to make the base body 1 align with the rainwater inlet when installing, therefore, the base body 1 is fixedly connected with a positioning column 23 at the bottom, and the two positioning columns 23 are symmetrically distributed with the bottom of the base body 1 as the center, by forming a positioning groove at the rainwater inlet and aligning the positioning column 23 with the inner wall of the positioning groove, the base body 1 can be accurately installed at the rainwater inlet.

[0033] In consideration of the fact that only the vertical grating 11 is relied on to block rainwater when the rainfall is relatively large, strong rainwater impact will cause the vertical grating 11 to tilt, thus, the surfaces of the plurality of arc-shaped buffer frames 3 are all arc-shaped; when the water flow impacts, the arc-shaped buffer frame 3 can effectively disperse the water flow impact force, reduce the direct action of the water flow on the vertical grating 11, and further enhance the stability and durability of the vertical grating 11.

[0034] The civil engineering grating for municipal construction is used, first, a positioning groove is formed at a rainwater inlet, the positioning column 23 is aligned with the inner wall of the positioning groove, so that the base body 1 is accurately installed at the rainwater inlet, at this time, the plurality of vertical gratings 11 are installed at the top of the base body 1, then, the positioning load-bearing block 22 is aligned with the positioning groove 21, with the help of a specific tool, the positioning load-bearing block 22 is gradually inserted into the positioning groove 21, so that part of the surface of the positioning load-bearing block 22 extends to the outside of the inner wall of the base body 1 through the positioning groove 21, until the bottom of the positioning load-bearing block 22 is in contact with the ground, then, a continuous force is applied to make the positioning load-bearing block 22 continue to move downward, until the surface of the positioning load-bearing block 22 is completely in contact with the top of the base body 1, at this time, the positioning load-bearing block 22 exerts a vertical downward pressure on the base body 1 by virtue of its large weight, and the base body 1 is firmly fixed to the ground, then the connecting rod 12 is inserted and fixed to the inner wall of the connecting groove 110, the plurality of vertical gratings 11 are connected into an integral structure, and the limiting rod 120 is inserted into the groove at the surface of the limiting rod 120 formed at the side of the rainwater inlet, so as to fix the vertical grating 11, at this time, when the rainwater passes through the vertical grating 11, the impact force of the water flow is first dispersed by the arc-shaped buffer frame 3, reducing the direct action on the vertical grating 11, and at the same time, impurities in the rainwater can also be blocked.
