Abstract

The utility model discloses a sand layer pipe jacking shield machine which structurally comprises a shield machine unit and a shield steel pipe of a jacking pipe; the key improvement includes that: the shield machine unit is a steel plate vertically arranged in a steel cylinder to form grid structure; a hydraulic jacking pick for adjusting the direction of the machine unit is arranged on the periphery of the connection end of the shield machine unit and the protective shield steel pipe. The utility model has the advantages that: as the shield machine unit adopts the grid structure, the small volume barriers can be cleaned manually, and only the sand in the shield steel pipe needs to be cleaned by workers during the jacking process, therefore the overbreak and collapse situations are effectively prevented, the pipe jacking construction speed is improved and the construction safety is also ensured.

Description

Layer of sand push pipe shield machine
Technical field
The utility model relates to a kind of tunneling equipment, particularly a kind of layer of sand push pipe shield machine.
Background technology
Along with expanding economy, various underground pipelines as: petroleum pipeline, natural gas line, storm sewer, sewage conduct demand increase day by day, some existing railways, building have become the only way which must be passed of these pipelines, particularly when passing through sand bed geology, for guaranteeing the safety of superstructure thing, general unit in charge of construction all needs to adopt the push pipe shield machine or adopts the mode of artificial shoveling jacking to construct.Existing push-bench has closed, open and semi open model, includes shield machine head and shield structure steel pipe in the structure, and key difference is the connected mode between shield machine head and the shield structure steel pipe.These two kinds of forms of construction work all have unsurmountable shortcoming: push pipe shield machine construction cost is high and can not handle the obstruction (diameter just may cause shield machine to shut down greater than the piece stone of 150mm) in jacking the place ahead, be unsuitable for below the railway bed this have under the assorted geological condition of filling out thing such as piece stone, rail, sleeper construct; The hand excavation is simple relatively, and expense is lower, but is not suitable for for the layer of sand soil property, because of the upright poor stability of layer of sand, and landslide easily in the jack-in process, the subgrade settlement that may cause that situation is serious influences rail track or road safety.
The utility model content
The utility model provides a kind of layer of sand push pipe shield machine, and with the easy clamping stagnation of conventional push pipe shield machine in the solution layer of sand jacking construction, and the problem that the hand excavation is caved in easily improves sand bed jacking construction speed, guarantees construction safety.
The technical scheme that is adopted is for achieving the above object: layer of sand push pipe shield machine, the shield structure steel pipe that comprises shield machine head, connection shield machine head and jacking pipe in its structure, its key improvements is: the shield machine head is that steel plate vertically is arranged on the lattice structure in the steel cylinder, and shield machine head and shield structure protection steel pipe link push up pick by the hydraulic pressure that is used to adjust shield machine head direction and be connected.
Above-mentioned shield machine head is a lattice structure, in its structure, fixedly installs plane, the place horizontal and vertical steel plate parallel with the steel cylinder axis on the steel cylinder inwall.
Above-mentioned hydraulic pressure top pick is evenly distributed on the inner peripheral wall of shield machine head and shield structure protection steel pipe link, and an end and shield machine head are hinged, and an other end is connected with shield structure protection steel pipe.
Above-mentioned shield machine head is identical with shield structure protection diameter of steel tube, dead in line.
Adopt the beneficial effect that technique scheme produced to be: the shield machine head adopts lattice structure, can when running into the small size obstruction, carry out the labor cleaning, and in jack-in process, only enter sand in the shield structure steel pipe with the labor cleaning, effectively prevent to backbreak, avoid the danger of caving in, improve jacking construction speed, guarantee construction safety.

The specific embodiment
For making above-mentioned purpose of the present utility model, feature and beneficial effect can become apparent more, below in conjunction with the utility model specific embodiment, the technical solution of the utility model are clearly and completely described.
Layer of sand push pipe shield machine, the shield structure steel pipe that comprises shield machine head, connection shield machine head and jacking pipe in its structure, its key improvements is: shield machine head 1 vertically is arranged on the interior lattice structure of steel cylinder for steel plate, and shield machine head and shield structure protection steel pipe 3 link peripheries are provided for adjusting the hydraulic pressure top pick 2 of heading.And consistent, the dead in line of diameter of the diameter of shield machine head 1 and shield structure protection steel pipe 3
Above-mentioned shield machine head 1 is a lattice structure, in its structure, and welding grid steel plate on the steel cylinder inwall, the steel plate plane is parallel with the steel cylinder axis, and the steel plate that is welded divides horizontal and vertical both direction to constitute lattice structure jointly.
Above-mentioned hydraulic pressure top pick 2 is evenly distributed on the inner peripheral wall of shield machine head 1 and shield structure protection steel pipe 3 links, and the top board that is provided with on an end and the shield machine head 1 is connected, and an other end and shield structure protect the annular backup pad that is provided with on the steel pipe inwall and weld.
In the concrete application process, because the shield machine head is identical with shield structure protection diameter of steel tube, so the external diameter of the concrete pipe of institute's jacking should be consistent with the external diameter of shield machine head, and the external diameter of standard concrete relay pipe link is less than the internal diameter of shield structure protection steel pipe 3, at first the shield machine that assembles is hung in operating pit during construction, the open end of shield structure protection steel pipe 3 is docked with the concrete relay pipe, at the concrete pipe afterbody of jacking big top pick is set and carries out jacking, in jack-in process, flow into the sand of shield machine protection steel pipe from the grid of shield machine head 1 by the labor cleaning, the grid that is arranged on the shield machine head 1 can slow down the speed that sand flows to shield structure protection steel pipe, the earth pressure balance that keeps the jacking end face to a great extent, and many jacking constructions all carry out at railway business line, though the track to the operation railway line before jacking supports, can not produce too big pressure at train through out-of-date, but layer of sand poor stability, the large tracts of land landslide will appear in case occur backbreaking, the layer of sand push pipe shield machine that the utility model is designed, be the sand of getting into shield structure protection steel pipe with the labor cleaning in jack-in process, can not cause landslide because of backbreaking.
