Description

The technical solution relates to devices for carrying out work in hydraulic engineering construction and can be used for the construction of pile bridge foundations, overpasses, transshipment complexes and berthing facilities in water areas.

The traditional technology and design of devices [10-13] for the construction of hydraulic structures, as a rule, includes watercraft for transporting piles and grillage elements to the mounting place, for example, platforms or pontoons equipped with special equipment. Moreover, such devices have lifting means (winches, cranes, jacks) located on the boats, as well as means for installing piles, including devices for drilling wells under piles. The erected hydraulic structure traditionally includes [13] pile supports with a grillage installed on them.

The main disadvantage of the known devices [10-13] is the significant complexity and cost of work due to the use of watercraft.

Modern technology [1-9] for the construction of hydraulic structures is based on the use of a remote (exposed) conductor of a special design for installation (driving into the ground) of pile supports and subsequent sequential installation of spans. Currently, technological complexes are known that are patented and efficiently used (see, for example: www.specfundament.ru) in hydraulic engineering: during the construction of pile bridge foundations in water areas [4, 7, 9], during the construction of bollards (RU42232U1, 27.11 .2004, RU42545U1, 12/10/2004) and coastal recreational complexes [6, 8], during the construction of flyovers [2, 3, 5].

Known technologies and complexes [2 - 9] are based on the pioneering technical solution according to patent RU41032U1, 10.10.2004 [1], which is taken as a prototype.

The technological complex [1] for the construction of a hydraulic structure (GTS) contains a working platform, a set of funds for the construction of a hydraulic structure, including pile supports with a grill of slabs installed on them, and the working platform is made in the form of a longitudinal horizontal slipway equipped with equipment and prefabricated elements for installation GTS, and the aggregate of funds for the construction of the GTS includes a lifting device, an installation for the installation of pile supports of the base of the GTS with sectional increase in spans of the GTS grillage and fashion s final assembly work. In this case, the lifting device is made in the form of a heavy crane, the installation for mounting pile supports includes a conductor frame set horizontally on the design axis along the span along the length and width of the span, with a conductor frame mounted on it, one end of which is mounted on the transverse metal crossbar of the span already mounted GTS, and the second remote end is installed on two pairs of support posts equipped with hydraulic drives, the first pair of which is mounted vertically on the bottom soil, and the second s installed obliquely at an angle of 15-25 ° to the vertical uprights. The conductor is equipped with openings made in the form of glasses for placing the pile supports at the design position by means of a crane and then immersing them in the bottom soil with a driven projectile to the required depth and fixing the stops located in the conductor openings. A transverse metal crossbar mounted by a crane and secured by a welded joint is mounted on the upper ends of the pile supports, and metal orthotropic plates are installed and fixed by a welded joint on the transverse crossbars of the hydraulic structures.

The complex [1] (and its subsequent modifications in [2-9]) is an effective technical tool for the construction of pile foundations of various hydraulic structures and is widely used in the practice of hydraulic engineering.

However, like other known devices [2–9], the technological complex [1] does not allow performing hydraulic structures with a variable span when using one (not replaceable by another) conductor frame.

The essence of the proposed technical solution is to create a technological complex for the construction of a hydraulic structure using a remote (exposed) conductor, the conductor frame of which can be used without replacement for the construction of hydraulic structures with a variable span.

The main technical result of the proposed technological complex for the construction of hydraulic structures is the expansion of the functionality and arsenal of devices for this purpose by using one universal conductor frame, which is used without replacement for the construction of hydraulic structures with different span lengths (from 3 to 24 m). The complex implements uninterrupted operation when changing the span length, reduces construction time and reduces the complexity and cost of work.

The technical result is achieved as follows.

The technological complex for the construction of a hydraulic structure (GTS) contains a working platform, a set of funds for the construction of hydraulic structures, including pile supports with a grill of slabs installed on them, and the working platform is made in the form of a longitudinal horizontal slipway, equipped with equipment and prefabricated elements for the installation of hydraulic structures, and the totality of means for erecting a hydraulic structure includes a lifting device, an installation for installing pile supports for the foundation of a hydraulic structure with section-wise extension of spans of a hydraulic structure and a module final installation work. In this case, the lifting device is made in the form of a heavy crane, the installation for mounting pile supports includes a conductor frame set horizontally on the design axis along the span along the length and width of the span, with a conductor frame mounted on it, one end of which is mounted on the transverse metal crossbar of the span already mounted GTS, and the second remote end is installed on two pairs of support posts equipped with hydraulic drives, the first pair of which is mounted vertically on the bottom soil, and the second s installed obliquely at an angle of 15-25 ° to the vertical uprights. The conductor is equipped with openings made in the form of glasses for placing the pile supports at the design position by means of a crane and then immersing them in the bottom soil with a driven projectile to the required depth and fixing the stops located in the conductor openings. A transverse metal crossbar mounted by a crane and secured by a welded joint is mounted on the upper ends of the pile supports, and metal orthotropic plates are installed and fixed by a welded joint on the transverse crossbars of the hydraulic structures.

The main difference of the complex lies in the fact that at the ends of the transverse metal crossbar of the GTS span already mounted, a pair of temporary support sockets is mounted that is welded together to support additional support pairs of struts made integrally with the conductor frame and placed in pairs on the lower side of the conductor frame along its longitudinal beams with step according to the expression

$$\text{l}=\text{L / (n}+\text{l), (1)}$$

where 1 is the distance between the pairs of additional support posts;

L is the length of the conductor frame;

n is the number of pairs of additional support legs.

In the specific case of performing hydraulic structures with a conductor frame length L = 24 m, the number n of pairs of additional support columns is from 1 to 7, depending on the specified length of mounted hydraulic structures spans with the possibility of erecting spans from 3 to 24 m long.

The complex is also distinguished by the fact that the crane and the installation for the installation of hydraulic structures are made with the possibility of sequential sectional growth of spans of the grillage by moving the crane to the installed slabs of the next span to expose the conductor frame with the conductor to the design position of the subsequent span of a given length straight or performed with branches of the hydraulic structure .

The drawing shows a General diagram of the design of the complex for the construction of hydraulic structures.

The GTS construction complex contains a working platform 1, pile supports 2, grillage 3, orthotropic plates 4, a crane 5, a conductor frame 6, a conductor 7, crossbars 8 with temporary support sockets, vertical support racks 9, inclined support racks 10, openings 11 conductor, longitudinal beams of the conductor frame 12, additional support racks 13.

The operation of the complex for the construction of hydraulic structures is illustrated by the following example (see drawing).

On the working platform 1, the grillage 3 contains the crane 5 and the prefabricated elements used in the construction of the GTS: pile supports 2 made in the form of large diameter metal pipes, metal transverse crossbars 8 and orthotropic (direct-directed) plates 4, as well as other equipment (not shown shown), including a driven-in projectile for driving pile supports to the required depth. The crane 5 exposes the conductor frame 6 with the remote conductor mounted on it 7. The conductor frame 6 and the conductor 7 are aligned horizontally on the design axes along the length and span of the mortar 3, while one end of the conductor frame 6 is mounted on a transverse metal crossbar 8 mounted span of the GTS, and the second remote end of the frame 6 is mounted on two pairs of support columns 9 and 10 equipped with hydraulic actuators. In the particular case for the crane 5 to expose the conductor frame 6 with the remote conduit 7 torus can be used traverse. A pair of support posts 9 is mounted vertically on the bottom soil, and the support posts 10 are mounted obliquely at an angle of 15-25 ° to the vertical posts 9 to prevent lateral wave and wind effects on the frame 6 and the conductor 7.

Pile supports 2 are fed into the openings 11 of the conductor 7 by the crane 5, which are installed at the design position and then immersed in the bottom soil to the desired depth with a driven projectile, followed by fixing by the stops placed in the openings 11 of the conductor 7. As a driven projectile for driving the pile supports 2 a hydraulic hammer, or a vibratory driver, or another driving device, moved from one pile support 2 to another by means of a crane 5, can be used.

Then, with the help of a crane 5, a crossbar 8 is started on the piles 2 with local adjustment and welding of the crossbar 8 with temporary support sockets and piles 2.

Then, on the transverse crossbars 8 of the already mounted and newly mounted sections, the GTS grillage 3 are installed and welded with orthotropic plates 4. After the installation of the next section (span) is completed, the grill 3 of the crane 5 is moved to the installed plates 4 to rearrange the frame 6 with the conductor 7 to the new design position, thereby realizing a sequential section-by-stage escalation of spans of the grillage 3 of a straight-line or performed with branches of the hydraulic structures.

When changing the span length (for example, when performing hydraulic structures with branches), the same universal conductor frame 6 is used, which is equipped with additional support pairs of racks 13, made integral with the conductor frame 6 and placed in pairs on the underside of the conductor frame 6 along its longitudinal beams 12 s step in accordance with the expression (1). The supporting pairs of uprights 13 are installed and fixed in temporary support sockets mounted on the transverse crossbar 8, for the implementation of a given length of the span of the GTS. For example, with a given span length of 24 m, the conductor frame 6 with a length of L = 24 m is set to full length, with shorter span lengths, by installing additional support posts 13 in the crossbar sockets 8, the conductor frame 6 is set to the corresponding length. The number n of pairs of additional support columns 13 from 1 to 7 allows you to expose the conductor frame 6 at a distance of 3 to 24 m (3, 4, 6, 8, 12, ... m) and build hydraulic structures with the corresponding span lengths that correspond to standard plate sizes grillage 3.

Thus, by using one universal conductor frame, which is used without replacement for the construction of hydraulic structures with different span lengths (from 3 to 24 m), the purpose of the complex with the specified technical result is achieved (expanding the functionality and arsenal of devices for this purpose, uninterrupted construction process, reduction of its terms, reduction of labor intensity and cost of work), which is in a causal relationship with a combination of essential features.
