Technical Field
The present invention relates to the technical field of trench support, and in
particular relates to a connection structure of a surrounding purlin and steel sheet
piles, a connection member thereof, and a trench support method.
Background Art
Larsen steel sheet pile support is a common form of trench support during
trench excavation. In the construction of Larsen steel sheet piles, comparatively
large gaps exist between a steel surrounding purlin and steel sheet piles, and uneven
force occurs; due to the long-term action of active earth pressure (or water
pressure), severe deformation of steel sheet piles and other phenomena may easily
appear, which may further affect safety of a foundation pit. As a result, a filling
measure using fine aggregate concrete is usually adopted in common design so as
to avoid this problem, but the construction procedure is cumbersome and the
material is unrecyclable. Therefore, based on a comprehensive consideration of
actual necessities at construction sites, a supporting structure, which can facilitate
the construction and make the entire supporting structure evenly forced, is needed
to meet the design requirements of construction.
In order to solve the above-mentioned technical problem, a Chinese Patent
CN205224051U provides a device for strengthening the supporting stability of
Larsen steel sheet piles, wherein the device comprises a steel surrounding purlin
located at an inner side of Larsen steel sheet piles, which are engaged and
connected to each other, and the steel surrounding purlin includes H-shaped steels
which are engaged and connected to each other; plural reinforcing plates are
provided between adjacent H-shaped steels, and parallel reinforcing plates are
provided between H-shaped steels, which are oppositely provided, so as to
strengthen the connection between the steel surrounding purlin and Larsen steel
sheet piles; however, limited by the length of reinforcing plates, the installation
position of reinforcing plates in the above-mentioned solution is fixed during
on-site construction, so the supporting strength of Larsen steel sheet piles depends
on the installation position of reinforcing plates. Specifically, the supporting
strength of steel sheet piles close to the reinforcing plates has been enhanced while
that of the steel sheet piles away from the reinforcing plates has not, so the problem
of uneven force has not been solved yet.

Following are embodiments of the connection member of a surrounding purlin
and steel sheet piles, and the connection structure thereof according to the present
invention. The steel sheet piles specifically are Larsen steel sheet piles 10, which
are connected to a surrounding purlin 20 so as to support the trench. Fig. 1 and Fig.
2 show a connection member (hereinafter referred to as the connection member) for
connecting the Larsen steel sheet piles 10 to the surrounding purlin 20, wherein the
connection member 30 comprises a ring sleeve 31 configured to sleeve the
surrounding purlin 20, and a supporting connector 32, one end of which abuts
against a Larsen steel sheet pile 10 while the other end is detachably connected to
the ring sleeve 31.
By means of the connection member 30, the gaps between the Larsen steel
sheet piles 10 and the surrounding purlin 20 can be supported, and the supporting
performance of the support component can be improved.
Fig. 3 shows a connection structure of the surrounding purlin 20 and the steel
sheet piles, comprising: the Larsen steel sheet piles 10, the surrounding purlin 20 and the connection member 30, wherein Larsen steel sheet piles 10 comprise a number of first steel sheets 11 provided at intervals, a number of second steel sheets
12 which are provided at intervals and are parallel to the first steel sheets 11, and
first connecting plates 13 which successively connect the first steel sheets and the
second steel sheets nose-to-tail; the surrounding purlin 20 is located at one side
close to the second steel sheets and extends along a direction parallel to the first
steel sheets 11 and the second steel sheets 12; in the connection member 30, the
ring sleeve 31 is provided to sleeve the surrounding purlin 20, and the position of
each ring sleeve 31 is in correspondence to that of each first steel sheet 11; one end
of the supporting connector 32 abuts against the first steel sheet 11 while the other
end is detachably connected to the ring sleeve 31.
In the connection member of the surrounding purlin 20 and the steel sheet
piles, one end of the supporting connector 32 of the connection member 30 abuts
against the first steel sheet 11 of the Larsen steel sheet pile 10, while the other end
is connected to the ring sleeve provided to sleeve the surrounding purlin 20, as a
result, the surrounding purlin 20 and the steel sheet piles can be reliably connected
without structure changes of Larsen steel sheet piles 10 and the surrounding purlin
20; moreover, the connection member 30 can be provided at different positions of
the steel sheet piles according to the situations, and can be mounted rather flexibly,
thereby ensuring high force evenness of the steel sheet piles and the surrounding
purlin 20.
Specifically, the second steel sheet 12 and the first connecting plate 13 of
Larsen steel sheet pile 10 are integrally molded, and the entire Larsen steel sheet pile 10 is formed as a number of frame steel sheets with a trapezoidal cross section after the first steel sheet 11, the first connecting plate 13 and the second steel sheet
12 are connected in sequence, wherein the first steel sheet 11 is located at an outer
side and is driven into a trench to be supported, the second steel sheet 12 is located
at an inner side, and the surrounding purlin 20 cooperates with the second steel
sheet 12.
Specifically, the supporting connector 32 comprises a supporting plate 321 and
a screw 322 connected thereto, wherein the screw 322 is in thread connection to the
ring sleeve 31 and makes the supporting plate 321 abut against the first steel sheet
11. More specifically, the screw 322 is perpendicular to and is in welded
connection to the surface of the supporting plate 321.
The afore-mentioned structure of the supporting connector 32 enables the
supporting plate 321 having a large area to abut against the first connecting plate 13,
and solves the problem of local force concentration. At the same time, the screw
322 is in thread connection to the ring sleeve 31, and thus is indirectly connected to
the surrounding purlin 20. Since the ring sleeves 31 are provided to sleeve the
surrounding purlin 20, the force concentration at the surrounding purlin 20 can also
be avoided.
Specifically, the surrounding purlin 20 comprises a third steel sheet 21 and a
fourth steel sheet 22 which are provided to be parallel to each other, and a second
connecting plate 23 between the third steel sheet 21 and the fourth steel sheet 22,
wherein the second connecting plate 23 is perpendicular to the third steel sheet 21
and the fourth steel sheet 22, and is integrated with the third steel sheet 21 and the fourth steel sheet 22, as a result of which the surrounding purlin 20 is formed as a profile steel with an H-shaped cross section.
Specifically, the ring sleeve 31 and the supporting connector 32 can be
connected in many ways. In one embodiment, the ring sleeve 31 is molded with a
thread blind hole at one side close to the first steel sheet 11, and the screw 322 is in
direct thread connection to the ring sleeve 31, as a result, the force at one side of
the ring sleeve 31 is concentrated, and the force of the ring sleeve 31 is uneven,
thereby affecting the support intensity of the surrounding purlin 20.
In another embodiment, as shown in Fig. 1, the ring sleeve 31 comprises a first
side wall 311 and a second side wall 312 respectively abut against an outer side of
the third steel sheet 21 and an outer side of the fourth steel sheet 22, and a third side
wall 313 and a fourth side wall 314 which are oppositely provide, thereby forming
the rectangular ring sleeve 31; the first side wall 311 and the second side wall 312
are provided with connecting holes at a region located at the outer side of the third
steel sheet 21 and a region located at the outer side of the fourth steel sheet 22, and
the screw 322 is provided to pass through the connecting holes so that the screw is
in thread connection to the ring sleeve 31 by means of a fastener.
More specifically, the first side wall 311 and the second side wall 312 are
respectively provided with two pairs of connecting holes, the two pairs of
connecting holes being symmetrically provided relative to the surrounding purlin
20.
The ring sleeve 31 is provided to be wider than the surrounding purlin 20, so
that the ring sleeve 31 and the supporting connector 32 are located at the outer side of the surrounding purlin 20; at the same time, the screw 322 can be provided to pass through two side walls of the ring sleeve 31, which are oppositely provided, so that the force born by the ring sleeve 31 is even and the support performance of the ring sleeve 31 is improved.
More specifically, a first nut 33 and a second nut 34 are provided to sleeve the
screw 322, wherein the first nut 33 and the second nut 34 are respectively located at
an outer side of the first side wall 311 and an outer side of the second side wall 312;
when the shown connection member 30 is mounted, the screw 322 of the
supporting connector 32 is provided to pass through connecting holes of the ring
sleeve 31, and the first nut 33 located at one side close to the Larsen steel sheet pile
10 is adjusted, so that the supporting plate 321 abuts against the first steel 11, and
the surrounding purlin 20 abuts against the second steel sheet 12; then the second
nut 34 located at one side away from the Larsen steel sheet pile 10 is adjusted so
that the ring sleeve 31 is locked onto the surrounding purlin 20. By means of the
first nut 33 and the second nut 34 located at both sides of the ring sleeve 31, the
screw 322 and the ring sleeve 31 are fastened, and the connection reliability of the
connection structure is further enhanced.
A trench support by using the connection member 30 of the surrounding purlin
20 and the steel sheet piles and by using the connection structure thereof, including:
driving Larsen steel sheet piles 10 into the trench, specifically, fixing and
connecting first steel sheets 11 of the Larsen steel sheet piles 10 to a trench wall of
the trench;
providing ring sleeves 31 to sleeve a surrounding purlin 20, wherein the number of the ring sleeves 31 is equal to that of the first steel sheets 11 so that the force on the Larsen steel sheet piles 10 and that on the surrounding purlin 20 are even, and providing the ring sleeves 31 at positions in correspondence to the first steel sheets 11; connecting the supporting connectors 32 to the ring sleeves 31 after construction of a support of the surrounding purlin 20, specifically, providing two of the first nuts 33 to respectively sleeve two of the screws 322, providing the screw 322 part of the supporting connector 32 to respectively pass through two connecting holes on the first side wall 311 and the second side wall 312 of the ring sleeve 31, adjusting the first nut 33 so that the supporting plate 321 of the supporting connector 32 abuts against the first steel sheet 11 of the Larsen steel sheet pile 10 and the surrounding purlin 20 abuts against the second steel sheet 12; and providing a second nut 34 at an end of the screw 322, and adjusting the second nut 34 to abut against a second side wall 312 of the ring sleeve 31 so that the ring sleeves 31 are locked onto the surrounding purlin 20.
Obviously, the above-mentioned embodiments are merely explanation of the
present invention rather than limits thereto. Ordinary technicians in this field can
make various modifications or changes based on the afore-mentioned explanation.
It is unnecessary and impossible to list all of the embodiments, and obvious
modifications and changes derived herefrom still fall within the scope of protection
