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.

Modern technology [1-7] 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 effectively used (see, for example: www.specfundament.ru) in hydraulic engineering: during the construction of pile bridge foundations in water areas [1, 5], during the construction of bollards (RU 42232 U1, 27.11. 2004; RU 42545 U1, 12/10/2004) and coastal recreational complexes [4, 6], during the construction of flyovers [2, 3].

As the practice of hydraulic engineering construction shows, the disadvantage of the known devices is that when driving the pile supports, some deviation of the pile head from the design position is possible, and this inaccurate driving prevents adequate placement of standard longitudinal and transverse spans on the piles of the crossbars.

The complex [1] was adopted as a prototype, which 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 [7].

The technological complex [1] for the construction of pile bridge foundations in the water area contains a working platform with mounting elements, as well as piling equipment located on the technological platform (TP) for immersing piles into the soil of the bottom of the water area, including a crane, a pile loader and at least one conductor for installation and orientation of pile supports, and TP is made with the possibility of movement in the direction of work. The jig is made in the form of a two-tier remote jig, the lower tier of which is equipped with supporting guides and holes for immersing piles, and the upper tier is made with openings in the form of glasses for placing piles on the design position by means of a crane, followed by immersing them in the ground with a pile loader and cutting them at design level.

However, when using the complex [1], as well as other known devices [2-6], inaccurate driving of piles is possible (deviation of the pile heads from the design position), which complicates the installation of crossbars and beams of standard dimensions on the pile heads. In this case, span mounting technology may be impaired.

The essence of the proposed technical solution is to create a technological complex for the construction of pile bridge foundations by driving piles into the ground, preventing violations of the technology of mounting bridge spans, which may be due to deviation of piles from the design position when driving them.

The main technical result of the proposed complex is the compensation of inaccurate driving of piles when they are immersed in the ground. The complex provides reliable and accurate installation of crossbars and beam spans of hydraulic structures, having standard sizes, on the heads of the piles cut off (clogged) at the design level.

The technical result is achieved as follows.

The technological complex for the construction of pile bridge foundations in the water area contains a working platform with mounting elements, as well as piling equipment located on the technological platform (TP) for immersing piles into the soil of the bottom of the water area, including a crane, pile loader and at least one conductor for installation and orientation of pile supports, and TP is made with the possibility of movement in the direction of work. The jig is made in the form of a two-tier remote jig, the lower tier of which is equipped with supporting guides and holes for immersing piles, and the upper tier is made with openings in the form of glasses for placing piles on the design position by means of a crane, followed by immersing them in the ground with a pile loader and cutting them at design level.

A distinctive feature of the complex is that metal glasses are installed on the heads of the piles submerged in the ground and cut off at the design elevation of the piles, while the condition

where D _article - the inner diameter of the glass;

D _St - the diameter of the piles,

and glasses are put on piles with the possibility of their movement in a horizontal plane.

As pile supports metal pipes of large diameter of 1000-2000 mm were used, as a rule, used in the construction of pile bridge foundations [1-6].

The complex is further characterized in that the inner diameter D _v cup mounted on the end walls are immersed in the ground and trimmed at the design level driving, the diameter D _binding piles 100-150 mm.

The drawing shows a General structural diagram of a technological complex for the construction of pile bridge foundations, where the following notation:

1 - hoisting mounting crane;

2 - technological platform TP;

3 - longitudinal support beam;

4 - transverse beam (crossbar);

5 - a metal cup mounted on the pile head;

6 - two-tier conductor;

7 - conductive nests;

8 - two-tier conductor frame;

9 - submersible piles.

The work of the technological complex for the construction of pile bridge foundations is as follows.

Mounting elements are placed on the working platform: pile supports 9 (which use large-diameter metal pipes of 1000-2000 mm), as well as longitudinal and transverse 3 and 4 support beams, metal glasses 5. A crane is used to immerse the pile supports 9 in the ground 1 and piling equipment (not shown in FIG.). On the heads of the immersed piles 9, equipped with cups 5, longitudinal 3 and transverse 4 beams (crossbars) are installed, on which the technological platform TP 2 with a conductor frame 8 and a two-tier conductor 6 is installed. The construction of the pile bridge base is carried out (similar to [1]) using TP 2 with its successive movement in the direction of work. In this case, by means of a crane 1, piles 9 are installed in the conductive sockets 7, then immersed (clogged) in the ground and cut at the design level.

In order to compensate for the inaccurate driving of piles 9 and the reliable (guaranteed) installation of the support beams 3 and 4 in the design position, metal glasses 5 are installed (put on) on the heads of the piles 9 that are submerged and cut at the design elevation. 1) allows for accurate and reliable installation of crossbars and beam spans of a hydraulic structure, having standard dimensions. Practice [7] shows that the deviation of the pile heads from the design position, as a rule, does not exceed 100-120 mm, so the inner diameter is chosen to be larger than the diameter of the piles by 100-150 mm.

For the implementation of the technological complex, known devices can be used: a conductor frame with conductor sockets, a pile loader (hydraulic hammer or vibro-loader), a technological platform described in [1]. Metal glasses 5, mounted on the heads of piles 9, are made according to the technology described in [7].

The proposed technical solution can be used both for the construction of pile bridge foundations in the water area [1, 2], and in the construction of unearthly flyovers and viaducts [3].

Thus, from the description of the technological complex and its operation, it follows that its purpose is achieved with the specified technical result (compensation for inaccurate driving of piles, guaranteed accurate placement of crossbars and beams in the design position on glasses, worn on the heads of the supporting piles), which is in the cause and effect connection with the set of essential features set forth in the formula of the proposed technical solution.
