Abstract

The utility model relates to a forced deviation correction device of a tube push bench, wherein the forced deviation correction device includes a tube push bench. The device is characterized in that: water spraying nozzles, which are inclined outwardly and are arranged on a shell at the back of the head of the tube push bench along the circumference; and water guns are installed at the inner side of the water spraying nozzles and at the head of the tube push bench and are connected with a high pressure water pump by water pipes. Besides, the water spraying nozzles are distributed at the shell at the back of the head of the tube push bench and are in four groups respectively at the right, left, up and down sides of the shell; and each group contains two water spraying nozzles. According to the utility model, advantages of the provided device are as follows: under the circumstances that hydro cylinder deviation correction can not be carried out, forced deviation correction can be carried out on the deviated axis of the tube push bench when there is a stiff-plastic soil layer, a sand layer, soft soils and a mixed soil layer during the construction by the tube push bench, so that the push pipe working can be carried out successfully.

Description

Push-bench is rectifying device by force
Technical field
The utility model relates to a kind of push-bench rectifying device by force.
Background technique
Push-bench is the equipment that is used for the pipeline of provided underground minor diameter; Generally be used for the city non-excavating construction; When push-bench is constructed in more uniform soil layer, than the direction of advance that is easier to control push-bench, and in case be in moulding soil layer, layer of sand, weak soil, mixed soil firmly, to construct; Often run into the different soil phenomenon is arranged on the same section; Make the excessive off-design requirement of push pipe axis, also be difficult to accomplish correction work with the oil cylinder on the push-bench correction this moment, just possibly produce when serious the push pipe operation stop or original push pipe operation is scrapped.Therefore the push-bench that needs to be resolved hurrily runs into the excessive problem of push pipe axis runout when moulding soil layer, layer of sand, weak soil, mixed soil firmly when underground construction.
Summary of the invention
The purpose of the utility model is to solve in the existing technology push-bench when underground construction, to run into when moulding soil layer, layer of sand, weak soil, mixed soil firmly existing push pipe axis runout and cross the problem that large tank is difficult to rectify a deviation, and a kind of push-bench rectifying device by force is provided.The utility model design push-bench is rectifying device by force; Comprise push-bench; It is characterized in that: oblique water orifice outside the housing upper edge circumference of push-bench head back offers, in each water orifice medial roof pipe die portion, hydraulic giant is installed, hydraulic giant connects high-pressure water pump by water pipe.It is characterized in that: water orifice is distributed in four groups up and down of housing of push-bench head back, and every group has two water orifices.The utility model has the advantages that can be under the situation that oil cylinder can't be rectified a deviation, and runs into when moulding soil layer, layer of sand, weak soil, mixed soil firmly at push-bench the push-bench off-axis is forced correction, and the push pipe operation can be carried out smoothly.
Description of drawings
Accompanying drawing 1 is the section of structure of the utility model, and Fig. 2 is the G-G transverse cross-sectional view of Fig. 1.
Embodiment
Comprise push-bench 1 among the figure, it is characterized in that: oblique water orifice 2 outside the housing upper edge circumference of push-bench head back offers, in each water orifice medial roof pipe die portion, hydraulic giant 3 is installed, hydraulic giant connects high-pressure water pump by water pipe.It is characterized in that: water orifice is distributed in four groups up and down of housing of push-bench head back, and every group has two water orifices.
When push-bench was constructed in moulding soil layer, layer of sand, weak soil, mixed soil firmly, running into had the different soil phenomenon on the same section, made the excessive off-design requirement of push pipe axis, also was difficult to accomplish correction work with normal oil cylinder correction.In certain water factory's jacking construction, specialized designs with high pressure water oblique impact structure.
The high pressure one-way valve is used in the outlet of oblique impact hydraulic giant, is made up of parts such as sliding valve core, spring, overcoats.The oblique impact hydraulic giant is in tilted layout to the muddy water storehouse at the push-bench operating room, uses high pressure slurry pump BW-320, and pressure P 10MPA controls through electric ball valve.
The oblique impact hydraulic giant is set around the push-bench, to the hard stratum one side by force override wash away, it is empty that the face that need entangle back is dashed, the push-bench deflection is dashed the face of sky, has reached the purpose of rectifying a deviation by force.

Claims (2)

1. push-bench rectifying device by force comprises push-bench, it is characterized in that: oblique water orifice outside the housing upper edge circumference of push-bench head back offers, in each water orifice medial roof pipe die portion, hydraulic giant is installed, and hydraulic giant connects high-pressure water pump by water pipe.
2. by the described push-bench of claim 1 rectifying device by force, it is characterized in that: water orifice is distributed in four groups up and down of housing of push-bench head back, and every group has two water orifices.
