TECHNICAL FIELD

[0001] The present application relates to the technical field of building construction, in particular to a structure and construction method of a pipe gallery water supply pipeline support embedded part. BACKGROUND

[0002] As an important part of the underground urban comprehensive pipe gallery, the water supply pipeline installation is a big difficulty due to its large diameter, limited space of the pipe gallery structure, and the characteristics of long distance, narrow space, and V-shaped structure. The construction of large-diameter water supply pipelines in the gallery will be a big difficulty. The construction of the support embedded part is the first step of pipeline construction. Due to the influence of pipeline installation space, the horizontal and vertical positions of the support embedded part need to be strictly controlled. The construction quality of the embedded part often determines the installation quality of the later support and pipeline.

[0003] The existing support embedded part is controlled by manual elevation line, so at least one person is needed to monitor each pipeline repair, resulting in increased labor costs, and manual control of the elevation line affects the accuracy of the data. Therefore, the existing construction method of the support embedded part has the technical problem of low reliability.

[0004] Therefore, there is an urgent need for a highly reliable support embedded part method in the art. SUMMARY

[0005] In view of the technical problem of low reliability of the existing support embedded part installation method, the purpose of the present application is to provide a structure of a pipe gallery water supply pipeline support embedded part, which can adjust the height, adapt to the height, reduce the cutting amount, and ensure the height and flatness of the embedded part during installation in the pipe gallery. On this basis, the construction method of the embedded part is improved, which can ensure the accuracy of the embedded position on the basis of reducing labor costs, improve the reliability of the support embedded part, and effectively overcome the problems existing in the prior art.

[0006] In order to achieve the above purpose, the present application provides a structure of a pipe gallery water supply pipeline support embedded part, which comprises a steel plate, a hook-shaped anchoring steel bar, and an adjustable screw rod. The steel plate is fixedly connected with a plurality of hook-shaped anchoring steel bars symmetrically distributed at the bottom. A plurality of adjustable screw rods are fixedly connected to the bottom of the steel plate. After the position of the embedded part is determined, the height of the embedded part is adjusted by adjusting the length of the exposed screw rod.

[0007] In order to achieve the above purpose, the present application provides a construction method of a pipe gallery water supply pipeline support embedded part, which comprises the following steps:

[0008] Step 1: Point cloud scanning of the gallery is performed by a robot to obtain the actual structure information of the gallery.

[0009] Step 2: Based on the actual structure information of the gallery obtained in step 1, a BIM model is established, the arrangement of the water conveying pipeline in the gallery and the model data of the support are obtained, and the installation elevation of the support embedded part is determined;

[0010] Step 3: Based on the model data obtained in step 2, the position of the support and the elevation control line of the embedded part are laid out by the laying robot;

[0011] Step 4: The left and right center points of the gallery are determined according to the "vertical diameter theorem", and the installation position of the embedded part is determined;

[0012] Step 5: According to the installation position determined in steps 3 and 4, the embedded part is punched and installed, and the embedded part is adjusted, so that the plane of the embedded part and the embedded part elevation control line are kept in a horizontal plane;

[0013] Step 6: After the embedded part is installed, the steel mesh is placed and the concrete is poured.

[0014] Further, the center point of the caliper is determined according to the "vertical diameter theorem", that is, the center point of the gallery, and the center point of the caliper can be directly projected onto the gallery structure by using a plumb instrument; After the center point of the gallery is determined, the line is laid out directly from the center point to the left and right according to the distance on the drawing to ensure that the embedded part can be arranged along the center point.

[0015] Further, in the process of laying out the line by the laying robot, the laying robot collects line displacement data through the sensor, calculates and processes the collected data, realizes real-time feedback and real-time adjustment of the laying position, and ensures the accuracy and efficiency of the laying.

[0016] Further, the installation hole of the support embedded part is blocked with a plastic bag to prevent the hole from being blocked during the later concrete transportation process.

[0017] Further, before placing the steel mesh and pouring the concrete, the left and right positions and elevations of the installed embedded part need to be reviewed.

[0018] Further, the gallery center point is re-measured by the level and caliper, and the left and right distances of the embedded part from the center point are reviewed; the elevation is controlled by the embedded part elevation control line of the laying robot before, and the front and rear elevations of the embedded part are adjusted to control the slope of the embedded part surface to be consistent with the slope of the gallery structure.

[0019] The pipe gallery water conveying pipeline support pre-embedded part structure and construction method provided by the application first adopts a robot to cooperate with a wire laying robot to obtain a control elevation line of the pre-embedded part, then determines the installation position of the pre-embedded part according to the center point of the gallery at the pre-embedded part position determined according to the "vertical diameter theorem", next adjusts the slope of the pre-embedded part according to the slope of the elevation control line at the pre-embedded part position, so that the slopes of the two positions are consistent, and finally installs the support pre-embedded part in a construction flow mode with concrete construction, which can not only reduce labor costs, but also ensure the accuracy of the pre-embedded position and improve the reliability of the support pre-embedded part.

[0027] In order to make the technical means, creative features, purposes and effects realized by the application easy to understand, the application will be further described below in combination with specific diagrams.

[0028] The pipe gallery water conveying pipeline support pre-embedded part structure provided by the application can realize height adjustment and can self-adapt to the height, so as to reduce the cutting amount and ensure the height and flatness of the installation of the support pre-embedded part in the pipe gallery. Figure 1 The support pre-embedded part structure 100 includes a steel plate 110, hook-shaped anchoring steel bars 120 and adjustable screw rods 130.

[0029] The steel plate 110 is fixedly connected to the symmetrically distributed hook-shaped anchoring steel bars 120 at the bottom, and the steel plate 110 is welded with the adjustable screw rods 130 at the bottom, and the height of the pre-embedded part 100 is adjusted by adjusting the length of the screw rods 130 exposed after the position of the pre-embedded part 100 is determined.

[0030] The existing support embedded part is affected by the pipeline installation space, and the installation position thereof needs to be controlled in height during installation. The installation of the existing support embedded part is controlled in height by manual operation. Therefore, there are technical problems of high labor cost and low control accuracy. In view of the technical problems, the application provides a method of the support embedded part formed by the above structure. The control height line of the embedded part is obtained by using a robot in cooperation with a wire laying robot. The installation position of the embedded part is determined according to the center point of the corridor at the support embedded part determined according to the “vertical diameter theorem”. Next, the slope of the embedded part is adjusted according to the slope of the height control line at the embedded part, so that the slopes are consistent. Finally, the support embedded part is installed in the form of construction flow of concrete construction. Therefore, the problems existing in the prior art can be solved, and the reliability of the support embedded part installation method is improved.

[0031] The method of the pipe gallery water conveying pipeline support embedded part provided by the application, as shown in Figure 2 includes the following steps:

[0032] Step 1: The actual structure information of the corridor is obtained by scanning the point cloud in the corridor by a robot.

[0033] In the scheme, the method of scanning the point cloud in the corridor by the robot is not limited. For example, the depth information can be calculated from the perspective camera to reconstruct the three-dimensional shape of the object, or the depth sensor such as Kinect or LiDAR can be used to directly obtain the scene depth information. In the scheme, the structure light scanning is preferably used, which can calculate the three-dimensional shape of the object surface by projecting a grating pattern and analyzing the deformation, and is suitable for high-precision three-dimensional scanning.

[0034] For example, Trimble TX8 three-dimensional scanner + Software software can be used to obtain data at a speed of 1 million accurate laser points per second. Only 2-3 minutes are needed for scanning at each station to complete the data set from each station.

[0035] The TX8 integrates a built-in camera. After completing data acquisition in the field, Trimble Realworks software can be directly opened. Trimble has a target automatic splicing technology, which automatically completes the registration operation. The coordinates of the target ball arranged on the known point are converted by Trimble Realworks software. The surface in the analysis module of Trimble Realworks software and the detection tool can compare and analyze the design model and the point cloud data, and obtain the three-dimensional model diagram of the corridor structure.

[0036] Step 2: as shown in Figures 3-4Based on the actual structure information of the gallery obtained in step 1, a BIM model is established, the arrangement of the water conveying pipeline in the gallery and the model data of the support are obtained, and the installation elevation of the support embedded part is determined.

[0037] In some embodiments, the collected point cloud information can be modeled by Trimble, the support arrangement of the water conveying pipeline is deepened according to the plan view, and the entity model is drawn in the gallery model; the data including the support pipeline and the like.

[0038] Due to the limited space of the pipe gallery and the dense pipeline, the pipeline needs to be accurately positioned in the up, down, left and right spaces to prevent the distance in one direction from being seriously over wide or the width in one direction from being too narrow. In addition, due to the structural deviation of the gallery, in order to avoid error accumulation and reduce the number of pipeline repair joints as much as possible, the pipeline needs to be finely modeled. The pipeline BIM arrangement of the present scheme can eliminate the construction error of the structure, obtain higher-precision embedded part model data, and has strong applicability.

[0039] Step 3: Based on the model data obtained in step 2, the position of the support and the elevation control line of the embedded part are configured by the line laying robot.

[0040] The line laying robot mainly lays out the control point coordinate information of each support in the actual gallery according to the model built by the point cloud model; the starting point is laid out according to the lowest determined standard section of the gallery; the data of the line laying is obtained according to the deepening of the point cloud model:

[0041] In the process of laying out by the line laying robot, the line displacement data is collected by the sensor, the collected data is scanned and collected by the data collector, enters the data collector, and is converted into digital quantity by A / D conversion. The computer calculates and processes these data, such as converting displacement into deflection, realizes real-time feedback and real-time adjustment of the position of the line laying, and ensures the accuracy and efficiency of the line laying.

[0042] Step 4: Determine the left and right center points of the gallery according to the "vertical diameter theorem", and determine the installation position of the embedded part.

[0043] Specifically, referring to Figure 5 The present scheme uses a caliper and a level, according to the "vertical diameter theorem", the perpendicular bisector of the chord passes through the center of the circle, and divides the arc opposite to the chord, so the center point of the caliper and the center point of the gallery must be on a vertical line.

[0044] Because the gallery is a standard circle and the length of the caliper is uniform, and the level can ensure that the caliper is in a horizontal state, according to the vertical diameter theorem, the center line of the caliper is equivalent to the vertical bisector of the chord of the circle, and the center point of the gallery must be located on the vertical projection of the center point of the caliper. The center point of the gallery can be directly projected onto the gallery structure by using a plumb line; after the center point of the gallery is determined, the layout is performed from the center point to the left and right sides according to the distance on the drawing to ensure that the embedded part can be arranged along the center point.

[0045] Step 5: According to the installation position determined in steps 3 and 4, the embedded part is punched and installed, and the embedded part is adjusted to keep the plane of the embedded part and the embedded part elevation control line in a horizontal plane.

[0046] First, according to the determined position, the hole is punched by using an electric drill, and the hole is blocked by using a plastic bag to prevent the hole from being blocked during the later concrete transportation process. The embedded part is produced in an industrial base and transported to the specified position gallery side wall to avoid blocking the transportation channel of the concrete transport vehicle,

[0047] The production of the support embedded part includes processes such as steel plate cutting, channel steel, and welding. After the steel plate, channel steel, and anchoring steel bar are welded, necessary corrosion protection treatment is performed to prevent corrosion.

[0048] During the production process, the quality of the materials is strictly controlled to ensure that the size, shape, and strength of the embedded part meet the design requirements. After the production is completed, preliminary quality inspection is performed to ensure that the embedded part has no obvious defects or damage.

[0049] Step 6: Referring to Figure 6 , after the embedded part is installed, the steel mesh is placed and the concrete is poured.

[0050] In some embodiments, the embedded part spacing is 6m, two for a section, after the installation of a section of embedded part is completed, the placement of the anti-cracking steel mesh and the pouring of the concrete in this section are performed, and then the next section of embedded part is embedded along the gallery direction.

[0051] Before the steel mesh is placed and the concrete is poured, the left and right positions and the elevation of the installed embedded part need to be reviewed.

[0052] The center point of the gallery is rechecked by using a level and a caliper according to the distance of the embedded part from the center point; the elevation is controlled by using the embedded part elevation control line of the previously laid robot, and the front and rear elevations of the embedded part are adjusted to control the slope of the embedded part surface to be consistent with the slope of the gallery structure.

[0053] The pipe gallery water conveying pipe support pre-embedded part structure and construction method formed by the above scheme, the support pre-embedded part structure formed by the above scheme is a prefabricated structure, which can be produced uniformly in an industrial base, reducing the occupation of the site, and at the same time, the support pre-embedded part structure is an adjustable support pre-embedded part structure, which can realize height adjustment, can be self-adaptive in height, so as to reduce the cutting amount and ensure the height and flatness of the pre-embedded part in the pipe gallery.

[0054] At the same time, based on the construction method formed by the adjustable support pre-embedded part structure, the accuracy of the pre-embedded position can be ensured on the basis of reducing the labor cost, and the reliability of the support pre-embedded part is improved.

[0055] The basic principles, main features and advantages of the present application are shown and described above. It should be understood by those skilled in the art that the present application is not limited by the above examples, and the above examples and descriptions in the specification are only to illustrate the principles of the present application, and various changes and improvements can be made without departing from the spirit and scope of the present application, and these changes and improvements all fall within the scope of the present application. The scope of protection of the present application is defined by the appended claims and their equivalents.
