Description
The technical field is as follows:
the utility model belongs to the technical field of the underground works pile foundation construction, concretely relates to steel protects a structure for utility tunnel is applicable to utility tunnel geology complex area construction.
Background art:
in recent years, the underground comprehensive pipe gallery in China has been developed rapidly and becomes an indispensable matched municipal facility in cities. The utility tunnel belongs to typical underground works, and its supporting construction adopts the bored concrete pile mostly. However, when construction is performed in a geological condition complex area and the mud retaining wall cannot meet requirements, all-steel retaining cylinders are required to be used for construction, generally, steel retaining cylinders are connected in a welding mode, but the mode is low in working efficiency, the steel retaining cylinders are prone to being damaged due to gas cutting during steel retaining cylinder recycling, and the turnover utilization rate of the steel retaining cylinders is low.
The utility model has the following contents:
the defect to prior art exists, the utility model provides an a steel protects a section of thick bamboo structure for utility tunnel improves the steel and protects a connection efficiency, reduces the steel and protects a damage, improves steel and protects a section of thick bamboo turnover rate of utilization.
The utility model provides a technical problem's technical scheme as follows:
steel casing structures for underground comprehensive pipe galleries, which comprise an upper steel casing, a lower steel casing and a casing connecting piece, wherein the lower end of the upper steel casing and the upper end of the lower steel casing are both provided with groove threads along the inner wall of the casing, the peripheries of the two ends of the casing connecting piece are symmetrically provided with convex groove threads matched with the groove threads, and the upper steel casing and the lower steel casing are fixedly connected through the casing connecting piece threads.
, the groove thread length corresponds to the tongue thread length of .
, the port size of the upper steel casing and the port size of the lower steel casing are both larger than the port size of the casing connecting piece.
Compared with the prior art, the utility model following beneficial effect has: the steel casing in the utility model has simple structure, the fixation between the steel casings is realized by the thread arranged on the casing connecting piece, the damage of the steel casing caused by the welding mode is avoided, and the resource is saved; in a steel protects a connection process, improve the connection efficiency that a steel protected a section of thick bamboo, easy and simple to handle, dress promptly, can dismantle fast simultaneously, improve a steel and protect a turnover rate of utilization, the practicality is strong.
Drawings
The present invention will be described in further with reference to the following drawings and detailed description:
fig. 1 is a schematic structural view of the middle steel casing of the present invention.
The numbers in the figures are as follows: 1-upper steel casing; 2-a casing connecting piece; 3-lower steel casing; 4-groove thread; 5-tongue and groove threading.
Detailed Description
Example 1
As shown in figure 1, steel pile casings for underground comprehensive pipe galleries comprise an upper steel pile casing 1, a lower steel pile casing 3 and a pile casing connecting piece 2, wherein the length of the upper steel pile casing 1 and the lower steel pile casing 3 is 2m, the thickness of the upper steel pile casing is 10mm, the length of the pile casing connecting piece 2 is 30cm, the thickness of the pile casing connecting piece is 10mm, the size of the port of the upper steel pile casing 1 and the size of the port of the lower steel pile casing 3 are both larger than the size of the port of the pile casing connecting piece 2, the lower end of the upper steel pile casing 1 and the upper end of the lower steel pile casing 3 are both provided with groove threads 4 along the inner wall of the casing, the peripheries of the two ends of the pile casing connecting piece 2 are symmetrically provided with convex groove threads 5 matched with the groove threads 4, the length of the groove threads 4 is corresponding to the length of the convex groove threads 5, and is 15 cm., and the upper steel pile.
The utility model discloses a steel protects a section of thick bamboo structure operation process 1) lay lower part steel protect a section of thick bamboo 3 to make the recess screw thread 4 of its section of thick bamboo inner wall up in the pore-forming, 2) will protect the tongue screw thread 5 of a connecting piece 2 end and aim at the recess screw thread 4 of a lower part steel protect a section of thick bamboo 3, then carry out fixed connection, 3) aim at the tongue screw thread 5 of a connecting piece 2 end with the lower extreme recess screw thread 4 of an upper portion steel protect a section of thick bamboo 1, then carry out fixed connection.
And (3) repeating the steps 1), 2) and 3) according to the depth of the formed hole until the structure of the steel casing reaches the designed elevation.
The utility model discloses a steel protects a simple structure, and is easy and simple to handle, improves the steel and protects a connection efficiency, reduces the steel and protects a damage, improves steel and protects a turnover rate of utilization.
The above is only a preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention should be covered by the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope defined by the claims.
The parts of the present invention not described in detail are the known techniques of those skilled in the art.
