Description
Technical Field
The invention relates to the technical field of flood control, in particular to a method for installing an embedded part of a flood control device.
Background
In recent years, with the gradual complexity and changeability of climate, most areas of China, especially Yangtze river basin, yellow river basin, Zhujiang river basin and even Songhua river basin, are greatly affected by flood disasters in rainy season, and the life and property safety of people is greatly affected by danger and serious influence.
Therefore, a novel flood protection device which is reliable in disassembly, convenient to use and easy to repeatedly use for many times is very suitable. The flood protection system may generally include an above-ground part exposed to the ground surface and an underground part located below the ground surface, wherein the above-ground part may include a plurality of pillars or piers spaced apart at a certain distance along the circumference of the flood protection area, and one or more water retaining devices such as fenders placed between the pillars. Whereas underground sections may generally include embedments, a typical embedment naturally forms the foundation for the above-ground section of a flood protection device and may generally include: the connecting part is used for being connected with the upright post and fixed together with the upright post, and the embedded component is positioned below the connecting part.
Indeed, the stability of the floor parts, such as the uprights and the skirts, is very important for such flood protection devices to be reliable in disassembly, easy to use and easy to use repeatedly. However, since the stability of the ground part is mainly ensured by the underground part, i.e. for example by embedments, the detachability thereof is mainly achieved by the detachability between the underground part and the underground part. It is common to install embedments and then assemble the aboveground parts.
Therefore, the installation method of the embedded parts of the flood protection device is very critical to the reliability and the flood protection effect of the whole flood protection device. Generally, the area for installing the embedment along the periphery of the flood control area generally includes two cases, one case is that the area is mainly composed of soft soil, so that a hard fixed foundation is formed in the soft soil in a way of concrete pouring in advance, so that the embedment is poured together with the concrete during the pouring process to form a stable underground part of the flood control device, and then the installation of the ground part of the flood control device is performed; another situation is that the area is formed by concrete poured previously, so that for the installation of the embedded parts, on the one hand, no repeated pouring of the concrete foundation is required, and on the other hand, if the existing foundation is completely removed and the concrete foundation is poured again, enormous labor, material and financial costs are incurred. Therefore, for such a regional road surface situation, it is urgently needed to provide an appropriate installation method of the embedded part.
Disclosure of Invention
In view of the above background, the present invention provides a method for installing an embedment member for a detachable flood protection device, which may include: the embedded part, a plurality of stand columns which are fixedly and detachably connected with the embedded part and baffles which are arranged between the stand columns. Wherein the embedment may include: a connecting portion such as a connecting plate for detachably connecting to and fixing with a column and a fastener insert below the connecting portion, the fastener insert may include a plurality of anchors configured to extend substantially in an elongated and straight line, and the installation method may include: firstly, drilling holes on the existing concrete foundation, wherein the depth of each hole is greater than the length of each anchoring piece, the size of each hole is suitable for the insertion of each anchoring piece, and the position of each hole corresponds to the position of each anchoring piece; then, placing the anchoring parts of the embedded parts into the holes; adjusting the position of the embedded part to a proper position; temporarily fixing the embedded part; and permanently fixing the embedded part in the temporary fixing state relative to the concrete foundation. This type of method is particularly suitable when the area to be embedded is itself made of previously cast concrete.
Advantageously, the anchor member may be placed into the drilled hole and then connected to the connecting portion, such as by welding. Naturally, it is also possible to first connect the anchoring element to the connecting part, for example by welding, and subsequently to place the anchoring element, which is formed integrally with the connecting part, into the drilled hole. The construction method has the advantages that constructors can flexibly select the construction steps according to site construction conditions and sizes and dimensions of the anchoring parts and the connecting parts.
Advantageously, the anchor may comprise a threaded sleeve and a threaded rod in threaded connection with the threaded sleeve, wherein the threaded rod may be in threaded connection with the threaded sleeve. Advantageously, the threaded sleeve is divided into an upper part and a lower part with an internal thread, which are separated by a partition wall in the middle, the lower part of which can be screwed with a threaded rod, and the upper part of which can be used for connection with the above-ground part of the flood protection device, i.e. the column, whereby it is achieved that the length of the anchor can be adjusted and, by means of the anchor with the threaded rod, it is also possible, if necessary, to achieve a screw connection or cooperation with other correspondingly threaded mechanisms or devices. Advantageously, the threaded rod may be provided with a thread distributed over its entire length or over a partial area. The partition wall has the effect that the threaded sleeve with the partition wall is stronger than in the case of a through-hole. Naturally, the internal threads of the upper and lower parts may be identical or different.
Advantageously, the step of adjusting the position of the embedment to the proper position may be performed using an adjustment device. First, an adjustment device can be fixed to the concrete or cement ground surrounding the borehole, and then the embedment is temporarily fixed relative to the adjustment device, such as to adjust the height and level of the adjustment device, which in turn adjusts the height and level of the embedment. The adjustment of the adjustment device may include coarse and fine adjustments depending on the construction situation and the requirements of the construction site.
Advantageously, the temporary fixing of the embedment can also be achieved by the adjustment device after the adjustment is completed. Naturally, other temporary fixing approaches or mechanisms are also conceivable. As long as the purpose is to temporarily fix the embedment in the adjusted position after the adjustment is completed. Naturally, in this case, after the embedment of the embedment is completed, the adjustment device must be removed for embedment installation of another embedment.
Advantageously, in the step of permanently fixing the embedment in the temporarily fixed state relative to the concrete foundation, first, the embedment which has been temporarily fixed is fixed at its bottom, that is, at the bottom of the anchor member which is inserted into the hole, for example, by first injecting the rebar planting glue into the air, and after the rebar planting glue is permanently solidified or fixed together with the surrounding concrete foundation and the bottom of the anchor member, the concrete is further poured on the solidified rebar planting glue until the concrete is substantially flush with the bottom of the surrounding concrete foundation. The main advantage of bar planting glue lies in, thereby can effectively realize anchor assembly and the cement foundation's around joint strength increase and ensure the pre-buried steadiness of whole built-in fitting. The further poured concrete has the effects that on one hand, the embedding stability of the embedded part can be realized in an auxiliary mode, and on the other hand, the concrete can be highly compensated or leveled with other ground concrete parts except the drilled hole.
Advantageously, after completion of the setting of the poured concrete, the temporary fixing means are removed, thereby completing the pre-embedding of the pre-embedded parts, so that the installation of the ground part of the flood protection device can then be carried out.
Advantageously, the temporary fixing means can also be retained after the completion of the setting of the poured concrete. This has the advantage that if the temporary fixing means do not hinder subsequent installation and other aspects of the flood protection system and if the fixing means are not re-usable, they can be left in place, so that the stability of the embedment can be further ensured.
Drawings
In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the drawings used in the description of the embodiments or the prior art will be briefly described below. It is to be understood that the drawings in the following description depict only some embodiments of the invention. These drawings are not intended to be limiting, but rather are intended to be exemplary. Wherein:
fig. 1 shows a flow chart of a method for installing an embedded part according to the present invention.
Detailed Description
Fig. 1 shows a schematic flow diagram of a method 200 for installing embedments for a removable flood protection device according to the present invention.
The installation method 200 according to fig. 1 is particularly suitable for the installation of embedments of a removable flood protection device. Such flood protection devices are usually constructed as wall-mounted flood protection devices or flood protection walls. The flood wall may generally include an embedment positioned below ground, a plurality of posts positioned above ground fixedly and removably coupled to the embedment, and a barrier positioned between the posts.
Wherein the embedment may generally include: a connecting part for detachable connection with the upright and fixed together, such as a connecting plate, and a fastener insert located below the connecting part, the fastener insert may include a plurality of anchors configured to extend substantially in an elongated and straight line. The connecting plate may be made of a metal plate, for example a stainless steel metal plate, typically having a thickness of at least 9 mm, thereby ensuring sufficient strength. The plurality of anchors, which are designed to be essentially elongate and extend in a straight line, can likewise be produced from a metal plate of the same material as the connecting plate. Wherein the connecting plate is used for connection with the column, such as by a threaded connection of a bolt. The embedded component is used for being connected with a foundation below the ground, so that the upright post can be kept stable under the condition of bearing flood pressure.
The method according to the invention is particularly suitable for the following cases: i.e. the area for embedding the embedment and thus mounting the studs is not itself constituted by a soft earth foundation but by a previously cast concrete structure.
According to fig. 1, the installation method may comprise: firstly, drilling holes on the existing concrete foundation, wherein the depth of each hole is greater than the length of each anchoring piece, the size of each hole is suitable for inserting the anchoring pieces, and the position of each hole corresponds to the position 201 of each anchoring piece; then, placing the anchors of the embedment into each hole 202; adjusting the position of the embedded part to a proper position 203; temporarily fixing 204 an embedded part; the embedment in the temporarily fixed state is permanently fixed 204 with respect to the concrete foundation.
The method 200 is described below according to a specific embodiment. Generally, the embedment of the detachable flood protection wall comprises a connecting plate and an embedment assembly.
Wherein the connecting plate is a metal plate made of stainless steel as described above, the thickness of which is at least 9 mm, whereby the strength thereof can be secured. A fastener insert is located below the web and in this embodiment includes a threaded sleeve and a threaded rod threadedly connected to the threaded sleeve. In addition, for the purpose of structural stability, a reinforcing plate or a reinforcing rib is also included in the embedded assembly. The threaded sleeve can be fixedly connected to the connecting plate, for example welded. The threaded sleeve is internally threaded, and has one end connected to the connecting plate for fixing the upright to the bolt and the opposite end screwed to the threaded rod. If necessary, a reinforcing plate is also connected to the threaded rod in a threaded manner.
According to the installation method 200 of fig. 1, first of all, a hole is drilled in the concrete foundation at the location to be embedded, wherein the depth of the hole is greater than the length of the anchor, i.e. the overall length of the threaded sleeve and the threaded rod together, and the size of the hole is adapted to the insertion of the threaded sleeve, since the threaded rod wall is thinner than the threaded sleeve, and in the case of a plurality of threaded sleeves and threaded rods, the location of each hole corresponds to the location of the respective threaded sleeve and threaded rod.
The threaded sleeve and threaded rod assembly may then be placed into the drilled hole and the upper end of the threaded sleeve and web may then be joined, such as by welding. It is naturally also an option to connect the upper end of the threaded sleeve to the connection plate, for example by welding, and then to place an insert, which is formed integrally with the connection plate, into the drilled hole. The construction method has the advantages that constructors can flexibly select the construction steps according to site construction conditions and sizes and dimensions of the anchoring parts and the connecting parts.
Furthermore, according to this embodiment, the threaded sleeve is divided into an upper part and a lower part with an internal thread, which are separated by a partition wall in the middle, the lower part of which can be screwed with a threaded rod, and the upper part of which can be used for connection with the above-ground part of the flood protection device, i.e. a column, whereby it is achieved that the length of the anchor can be adjusted, and by means of the anchor with the threaded rod, it is also possible to achieve a screw connection or cooperation with other correspondingly threaded mechanisms or devices, if necessary. Advantageously, the threaded rod may be provided with a thread distributed over its entire length or over a partial area. The partition wall has the effect that the threaded sleeve with the partition wall is stronger than in the case of a through-hole. Naturally, the internal threads of the upper and lower parts may be identical or different.
Then, the position of the embedded part is adjusted to a proper position by using an adjusting device such as an adjusting tool. Specifically, first, the adjusting tool may be fixed on the concrete or cement ground around the drill hole, then the embedded part and the adjusting tool are relatively and temporarily fixed together, and the adjusting device, such as the height and the level, is adjusted, and the height and the level of the embedded part are adjusted. The adjustment of the adjustment device may include coarse and fine adjustments depending on the construction situation and the requirements of the construction site.
And then, temporarily fixing the adjusted embedded part. Here, the temporary fixing of the embedded part is simultaneously realized through the adjusting tool after the adjustment is completed. Therefore, the dual functions of adjustment and fixation can be simultaneously realized through one adjusting tool.
Naturally, other temporary fixing means or mechanisms are also conceivable, such as an overhead or a drop-down temporary metal boom or a metal support. As long as the purpose is to temporarily fix the embedment in the adjusted position after the adjustment is completed. Naturally, under the corresponding circumstances, after the pre-burying of the embedded parts is completed, the adjusting tool needs to be detached for the pre-burying installation of other embedded parts.
And finally, permanently fixing the embedded part in the temporary fixing state relative to the concrete foundation. Specifically, according to this embodiment, first, the embedded part that has been temporarily fixed is fixed at its bottom, that is, at the bottom of the threaded rod that extends into the hole, and then the bar-planting glue is first injected into the hole, and after the bar-planting glue, together with the surrounding concrete foundation and the bottom of the threaded rod, has been permanently set or fixed, concrete is further poured onto the set bar-planting glue until it is substantially flush with the bottom of the surrounding concrete foundation.
The main advantage of bar planting glue lies in, thereby can effectively realize the threaded rod bottom in the hole and the joint strength increase of cement foundation on every side and ensure the pre-buried steadiness of whole built-in fitting. The effect of the concrete poured subsequently is that on one hand, the embedded stability of the embedded part can be realized in an auxiliary mode, and on the other hand, the concrete poured subsequently also can be used for height compensation or leveling with other ground concrete parts except the drilled hole. Naturally, in addition to this type of construction, fixing means that achieve the same effect are also conceivable, as long as the purpose and effect are similar or identical.
According to the present embodiment, after the completion of the solidification of the poured concrete, it is necessary to remove the temporary fixing means, i.e., the adjustment tool, thereby achieving the completion of the embedment, so that the installation of the ground portion of the flood control device can be subsequently performed. Alternatively, for certain fixing means or measures, after the setting of the poured concrete has been completed, temporary measures can also be retained and then made permanent. The flood protection device has the advantages that if the temporary fixing measures do not hinder subsequent installation and other aspects of the flood protection device and the fixing measures are not reusable, the temporary fixing measures can be completely kept, so that the stability of the embedded part can be further ensured, the work of clearing the tool is reduced, and the time and the cost are further saved.
The previous description of the disclosed embodiments is provided to enable any person skilled in the art to make or use the present invention. It should be understood that the features disclosed in the above embodiments may be used alone or in combination, except where specifically noted. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein may be applied to other embodiments without departing from the spirit or scope of the invention.
