CN2549295Y - Horizontal operation of pneumatic hammer through prestressed concrete culvert pipe - Google Patents

Abstract

The utility model relates to a horizontal operation of pneumatic hammer through prestressed concrete culvert pipe. The inside of a concrete pipe(1) forms a rubber sleeve and is penetrated with a steel pipe(3). Such construction technique of horizontal penetration solves the difficulty that the pneumatic concrete culvert pipe hammer cannot enter the concrete pipe, and can enable the GRUNDORAM-pneumatic concrete culvert pipe hammer to enter the concrete pipe so as to achieve multiple functions.

Description

The pneumatic rammer level is passed through prestressed concrete culvert pipe with great

(1) technical field:

The utility model belongs to the culvert pipe of the rivers of highway crossing, railway and narrow runner, particularly relates to the pneumatic rammer level and passes through prestressed concrete culvert pipe with great.

(2) background technique:

Pass through the culvert pipe of the rivers of small-sized narrow runner, culvert pipe is laid in construction after the draining of can damming, the culvert pipe of highway crossing, railway, and the construction of all need stopping transport, long in time limit, the operating expenses height, the construction back influences the quality on roadbed or road surface simultaneously.As adopt the concrete culvert pipe, when passing through, crack even damage after culvert pipe is stressed with the pneumatic rammer level.

(3) model utility content:

Technical problem to be solved in the utility model is at the problem that exists in the background technique, and provides a kind of pneumatic rammer level of utilizing mechanical execution to shorten the cycle to pass through prestressed concrete culvert pipe with great.

The invention for solving the technical problem can reach by following technical solution:: in the concrete pipe, constitute the rubber cushion cover and be installed with steel pipe.

During construction, steel pipe is added in employing in concrete pipe, bear the impulse force of hammer ram by steel pipe, shaking force and radial shear power that hammer ram is produced concrete pipe in the ramming of continuous long distance forward on the steel pipe of center, to reduce crackle, the SOL of the stressed generation of culvert pipe, guarantee that culvert pipe passes through, and reaches design standard.

The utility model is compared with the above-mentioned background technology can have following beneficial effect: the horizontal crossing construction technology of this kind, solve pneumatic punner-pipe hammer and can not ram the into difficult problem of concrete pipe, it can utilize the GRUNDORAM-pneumatic punner-pipe hammer to ram into steel pipe and concrete pipe, reaches the one-machine multifunction purposes.

(4) description of drawings:

Accompanying drawing is this culvert pipe configuration diagram.

(5) embodiment:

Below in conjunction with the drawings and specific embodiments will the utility model is described in further detail:

By shown in Figure 1: in concrete pipe 1, constitute rubber cushion cover 2 and be installed with steel pipe 3.

In such scheme, be convenient and install that the center steel pipe will be made more piece, every joint can intert a plurality of concrete pipe, between the steel pipe of every joint center with the Placement of socket joint.Available rubber plate or fine cordage are done cushion between steel pipe and concrete pipe, do cushion with fine cordage between the concrete pipe plane of structure.The center steel pipe both was connected with pneumatic punner-pipe hammer can carry out horizontal crossing construction.

Claims (1)

1, a kind of pneumatic rammer level that relates to is passed through prestressed concrete culvert pipe with great, contains concrete pipe (1), it is characterized in that: constitute rubber cushion cover (2) and be installed with steel pipe (3) in concrete pipe (1).
